Background/Objectives: Older women who habitually wear makeup exhibit better cognitive and psychological functioning. However, physical characteristics associated with habitual makeup use in this population remain unclear. We aimed to evaluate physical, cognitive, and psychological characteristics of community-dwelling older women who habitually use makeup. Methods: This health survey included 295 community-dwelling women aged ≥65 years. Weekly makeup use frequency; cosmetic types used; grip strength; sit-and-reach distance; one-leg standing time; maximum walking speed; and scores on timed up-and-go (TUG) test, Mini-Mental State Examination, Geriatric Depression Scale-5 (GDS-5), and EuroQol 5-Dimension 5-Level (EQ-5D-5L, Japanese version) were statistically analyzed and compared between makeup and non-makeup groups. Further, the following four groups, based on lipstick and eyebrow product use, were compared: lipstick users, eyebrow products users, both-users, and neither-users. Results: The make-up group had lower age (p = 0.001), lower TUG scores (p = 0.011), lower fastest walking speed (p = 0.022), and lower GDS-5 scores (p = 0.009) and higher grip strength (p = 0.011), one leg standing time (p = 0.008), and EQ-5D-5L scores (p = 0.049). After adjusting for age, the make-up group showed significantly lower GDS-5 scores (p = 0.008) and higher EQ-5D-5L scores (p = 0.038). Comparison by cosmetic types revealed significantly lower age (p = 0.004) and TUG (p = 0.007), GDS-5 (p = 0.002), and EQ-5D-5L (p = 0.034) scores and higher EQ-5D-5L scores in users than in non-users. Multinomial logistic regression analysis revealed a significant association with TUG (odds ratio [OR], 0.653; 95% confidence interval [CI], 0.448–0.952) and GDS-5 (OR, 0.592; 95% CI, 0.415–0.843) in both-users. Conclusions: Habitual lipstick and eyebrow cosmetic use may be associated with improved mood, quality of life, and dynamic balance in older women. Full article

Sunlight contains a wide spectrum of radiation from ultraviolet (UV) through visible light to infrared (IR). UV radiation plays a crucial role in skin damage, photoaging, and carcinogenesis, necessitating effective photoprotection strategies. The study evaluated the efficacy of protective lipsticks with different sun protection factor (SPF) values (10, 15, and 30) against UVA and infrared (IR) radiation. In this study, the directional-hemispherical reflectance (DHR) was measured across various spectral bands (335–380 nm, 400–540 nm, 700–1100 nm, and 1000–1700 nm) with SOC 410 Reflectometer (San Diego, CA, USA). Since the device used in this study did not cover the UVB range (290–320 nm), this study does not provide a direct assessment of SPF in its conventional sense. The measurements were taken at four time points up to 120 min after lipstick application. Results indicated that lipsticks with higher SPF values significantly altered skin reflectance in UVA and IR ranges, with SPF30 showing the lowest reflectance in the UVA range (335–380 nm), suggesting greater absorption of UVA radiation by the product and significantly higher reflectance in IR ranges compared to lower SPF lipsticks. Reflectance values generally increased over time post-application for key spectral bands. These findings demonstrate that SPF lipsticks provide variable attenuation of UVA and IR radiation, highlighting their role in comprehensive lip photoprotection. The data support the importance of SPF selection for optimized protection, especially against penetrating UVA and IR components of sunlight. Full article

Transparent coatings with superwetting properties (superhydrophilicity or superhydrophobicity) have broad application prospects. Usually, most studies have been carried out separately on superhydrophobic coatings or superhydrophilic coatings. In our work, superhydrophilic transparent coatings were prepared by the four-mercapto and four-polyethylene glycol monomethyl acrylate modified POSS (POSS-(SH)₄-(PEGMA)₄) (designated as I-coating) as well as superhydrophobic transparent coating (designated as O-coating) were prepared with the mercapto and seven-heptyl decafluoroheptyl acrylate modified POSS (POSS-SH-(DFMA)₇). The similarities and differences in anti-fogging, stain resistance, self-cleaning and anti-biological application between superhydrophobic and superhydrophilic coatings were compared systematically. The results show that superhydrophilic coatings performed better at preventing fog and facilitating self-cleaning; nevertheless, superhydrophobic coatings exhibited superior efficacy in the removal of contaminants such as markers and lipsticks. Both superwetting coatings demonstrated proficiency in self-cleaning and in deterring biological adhesion with respect to low-viscosity oil droplets. The relevant research of this paper provided a reference for the subsequent study on the advantages and disadvantages of superhydrophilic and superhydrophobic as well as its specific application.

The cosmetic market is constantly evolving and ever-changing, particularly with the introduction and incorporation of nanotechnology-based processes into cosmetics for the production of unique formulations with both aesthetic and therapeutic benefits. There is no doubt that nanotechnology is an emerging technology for cosmetic formulations. Among the numerous cosmetic items, incorporating nanomaterials has provided a greater scope and is commonly utilized in facial masks, hair products, antiaging creams, sunscreen creams, and lipsticks. In cosmetics, nanosized materials, including lipid crystals, liposomes, lipid NPs, inorganic nanocarriers, polymer nanocarriers, solid lipid nanocarriers (SLNs), nanostructured lipid carriers (NLCs), nanofibers, nanocrystals, and nanoemulsions, have become common ingredients. The implementation of nanotechnology in the formulation of face masks will improve its efficacy. Nanotechnology enhances the penetration of active ingredients used in the preparation of face masks, such as peel-off masks and sheet masks, which results in better effects. The emphasis of this review is mainly on the formulation of cosmetic face masks, in which the impact of nanotechnology has been demonstrated to improve the product performance on the skin.

One of the challenges of the pharmaceutical and cosmetic industries is to deliver biochemical compounds that can be advantageous for the skin. Research on Boraginaceae taxa has confirmed their use in traditional medicine and proved the potential biological importance of various molecules in cosmetology. The main classes of valuable compounds associated with Boraginaceae taxa are fatty acids, including γ-linolenic acid, essential oils, phenolic acids (e.g., rosmarinic acid), flavonoids, anthocyanins, tannins, and saponins. Highly specific are naphthoquinone pigments (including shikonin) and allantoin. Another distinguishing feature is the accumulation of silica (silicon dioxide) in trichomes. Some taxa produce mucilages. However, pyrrolizidine alkaloids (PAs) with toxic properties are also found (mainly in Symphytum spp.); therefore, their applications should be avoided. Extracts or individual compounds of Boraginaceae plants are characterized by antioxidant, anti-inflammatory, antiseptic, anti-irritant, antiaging, and photoprotective activities. Boraginaceae products are widespread in the cosmetic industry as ingredients of creams, balms, lotions, gels, shampoos, lipsticks, perfumes, and deodorants. The most valuable for the cosmetic industry are raw materials obtained from the genera Alcanna Anchusa, Arnebia, Borago, Buglossoides, Cerinthe, Cordia, Echium, Ehretia, Eriodictyon, Glendora, Lappula, Lithospermum, Lycopsis, Macrotomia, Maharanga, Mertensia, Messerschmidia, Myosotis, Omphalodes, Onosma, Pulmonaria, Rindera, Symphytum, Trachystemon, and Trigonotis. Further research should focus on the search for active substances in other plants of the family. Full article

Phthalate esters are commonly included in the formulations of cosmetics and related products in order to retain fragrance, enhance flexibility (i.e., by acting as plasticizers), facilitate the dissolution and dispersion of other ingredients, and improve the overall texture and sensory experience of the products. This study aimed to assess the presence and concentrations of phthalates in cosmetics by analyzing a comprehensive set of samples collected over a period of five years (2016–2020). The concentrations of nine different phthalate esters (BBP, DEHP, DNOP, DPP, DBP, DIPP, DMEP, DMP and PIPP) in 1110 cosmetics samples from France and Spain were determined by gas chromatography–mass spectrometry. The samples were included in five categories: soaps and shampoos; hand and body creams; lip gloss and lipsticks; nail polish; and facial makeup and skincare products. Some of the samples (4.86%) contained at least one phthalate at concentrations above the threshold limit (1 µg mL⁻¹). Variable concentrations of different phthalates were determined in the 54 positive samples identified. DEHP was the most frequently detected phthalate, followed by DBP. The findings revealed different profiles according to the different categories of cosmetics and the phthalates detected in each. The results were critically compared with those obtained in various previous studies. Full article

A new green and highly sensitive method for the determination of rhodamine B (RhB) by deep eutectic solvent-based vortex-assisted liquid–liquid microextraction with fluorescence detection (DES-VALLME-FLD) was developed. The extraction efficiency of conventional solvents and different deep eutectic solvent (DES) systems composed of tetrabutylammonium bromide (TBAB) and an alcohol (hexanol, octanol, or decanol) in different ratios were compared. DFT calculations of intermolecular electrostatic and non-covalent interactions of the most stable RhB forms with DES and water explain the experimental DESs’ extraction efficiency. Semiempirical PM7 computations were used to obtain Hansen solubility parameters, which supported the good solubility of the monocationic RhB form in selected DESs. The dependence of the linear calibration of microextraction into 100 µL DES was observed in the RhB calibration range from 0.2 to 10.0 µg L⁻¹ with a correlation coefficient of R² = 0.9991. The LOD value was calculated to be 0.023 µg L⁻¹. The accuracy and precision of the proposed method were verified over two days with RSD values of 2.9 to 4.1% and recovery of 94.6 to 103.7%. The developed method was applied to the determination of RhB in real samples (tap water, energy drink, and lipstick). Full article

Cosmetics are a staple in daily beauty routines worldwide, embraced for their role in enhancing personal appearance and self-care. However, their direct application exposes the skin to a range of ingredients, including metal(loid)s, and these can have a hazardous impact on human health if they exceed the limits defined by regulatory agencies. As a result, it is important to evaluate metal(loid) levels to ensure the safety of these cosmetic products. This research aimed to analyze several cosmetic products (massage cream, cleaner, mud mask, skin polish, scrub, lipstick, foundation, lotion, face powder, and highlighter) for metalloids (Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, As, Sb, Cd, Pb, Bi, and Hg) by using inductively coupled plasma-optical emission spectrometry (ICP-OES). Multivariate and bivariate statistical approaches were used to interpret the sources and association between the metal(loid)s. The concentration ranges of metals were found to be Al (1.18–4.15 mg/kg), Cr (0.13–2.19 mg/kg), Mn (1.89–28.77 mg/kg), Fe (4.09–126.02 mg/kg), Co (0.19–31.62 mg/kg), Ni (0.11–5.39 mg/kg), Cu (0.08–0.19 mg/kg), Zn (1.99–47.81 mg/kg), Sr (0.99–10.34 mg/kg), Cd (0.16–1.50 mg/kg), Pb (0.29–2.44 mg/kg), Bi (0.23–2.18 mg/kg), and Hg (0.012–0.42 mg/kg), whereas the concentration ranges of metalloids were found to be As (0.011–0.051 mg/kg) and Sb (0.042–1.66 mg/kg). Among the tested cosmetic products for the metal(loid) levels, the estimation of the margin of safety (MOS < 100), hazard quotient (HQ > 1), hazard index (HI > 1), and cumulative cancer risk (LCR ≤ 1 × 10⁻³) indicated non-carcinogenic and carcinogenic health risks associated with the use of few products. Most of the cosmetics products under investigation are safe with respect to non-carcinogenic and carcinogenic health risks. By highlighting the need to limit excessive use and adhering to sustainable safety practices, this study underscores the importance of monitoring and regulating metal(loid) content to ensure consumer safety and mitigate environmental impact.

Titanium dioxide (TiO₂) plays a pivotal role in photocatalytic reactions and holds great promise for the cosmetic and paint industries due to its white color and high refractive index. However, the original color of TiO₂ changes gradually to blue or yellow with UV irradiation, which affects its color realization. We encapsulated TiO₂ with several natural organic dye compounds, including purpurin, curcumin, and safflower, to control its photochromism and realize a range of different colors. The chemical reaction between TiO₂ and dyes based on their functional group was investigated, and the light absorption was tested via FTIR and UV–Vis spectroscopy. The changes in morphology and size distribution additionally supported their successful encapsulation. The discoloration after UV irradiation was evaluated by measuring the color difference (ΔE) of control TiO₂ and dye encapsulated TiO₂. The unique structure utilized natural dyes to preserve photochromism based on the physical barrier and automatically controlled the electronic transition of core TiO₂. In particular, the color difference values of purpurin and curcumin were 4.05 and 3.76, which is lower than the 5.36 of the control TiO₂. Dye encapsulated TiO₂ was manipulated into lipstick to verify its color realization and retention. Full article

Titanium dioxide (TiO₂) is a safe inorganic ultraviolet (UV) filter with activity against UV damage. However, the recombination of the carrier’s charge and the tendency for TiO₂ aggregation are the main disadvantages. Substrate supports, such as mesoporous silica, are biocompatible strategies to incorporate TiO₂, altering its interaction with the skin. Since the lips are sensitive to the adversities of the environment, including UV radiation, the application of lipstick sunscreens is of great importance and expected to provide protection for this particular area against sunburn and photoaging, among other unfavorable responses unprotected UV exposure. We investigated the in vitro photoprotective efficacy and photostability of lipstick formulations containing TiO₂ incorporated into mesoporous silica (SBA-15). The samples were the lipstick base; SBA-15; TiO₂ (free form); and TiO₂ incorporated into SBA-15. The photoprotective efficacy was characterized in vitro using a Labsphere UV2000S. Lipsticks were irradiated in a Suntest CPS+ chamber to evaluate functional photostability. Lipstick base and SBA-15 alone did not display photoprotective efficacy. The sample containing 10.0% TiO₂ incorporated into the mesoporous silica generated greater photostability and sun protection factor (SPF) value compared to the one containing only 10.0% TiO₂ (free state). Our findings suggest that TiO₂ + SBA-15 can be considered a broad-spectrum ingredient for innovative sunscreens, particularly for the photoprotection of the lips. Full article

The recycling of food and agricultural waste, which is released as a result of domestic and agricultural uses, instead of throwing them into the garbage cycle and the environment, is of great importance both for the protection of the environment and the minimization of other environmental pollutants. In recent years, human population growth, pandemic developments (COVID-19), climate change and global warming have increased significantly. These increases endanger environmental health. Therefore, researchers are investigating different alternatives in terms of both human and environmental health. This paper evaluates the possible use of the shell part of the peanut, which is a food with high nutritional value. Peanut (Arachys hypogaea) is a plant from the Fabaceae family. Peanut is a valuable food product with a wide range of uses all over the world. Their shells are an indispensable part of the garbage cycle and have a fibrous and lignocellulosic (cellulose content: 45%, hemicellulose content: 6%, lignin content: 36%) structure. In addition, it has a very slow degradation rate under natural conditions, which is a great advantage for other wastes. Today, most peanut shells are disposed of by incineration and burial, which causes environmental pollution. For this reason, this waste should be used in various sectors with a zero waste approach. Increasing environmental pollution all over the world day by day, unconscious energy consumption and climate change have led countries to seek alternative solutions for environmental issues and to develop environmentally friendly-technological methods. Peanut shell is used intensively in fields such as compost material, energy sector (biofuel, biodiesel, CO₂ emission reduction, etc.), cosmetics (nail polish, lipstick, etc.), soil improvement, drinking water and wastewater treatment (adsorbent, nanomaterial, filter etc.). In this study, the use of peanut shells from Osmaniye province as an environmentally friendly, economical and easily available biosorbent was investigated. Full article

Aeschynanthus pulcher (Blume) G. Don, the “lipstick plant” is a prized ornamental plant with distinctive flowers. Here, we introduce a novel in vitro regeneration method for A. pulcher using leaf explants and an optimized combination of phytohormone plant growth regulators (PGRs). The optimal conditions for shoot regeneration included 1 mg L⁻¹ polyvinyl pyrrolidone (PVP) plus 3 mg L⁻¹ thidiazuron (TDZ), inducing a response rate of 82.4% and a shoot/explant ratio of 38.6. When the Murashige and Skoog (MS) medium contained indole-3-butyric acid (IBA) alone, leaves first differentiated into adventitious roots and then adventitious shoots. Leaves cultured on MS medium containing 1 g L⁻¹ PVP, 3 mg L⁻¹ TDZ, 5 mg L⁻¹ casein, and 0.1 mg L⁻¹ α-naphthaleneacetic acid (NAA) for 30 d exhibited the highest embryogenic callus (EC) induction rate (95.6%). The optimal shoot proliferation coefficient (21.5) was obtained when shoots derived from EC were cultured on the same medium as that used for EC induction for 5 weeks. The most effective medium for rooting of elongated shoots was MS medium containing 1 g L⁻¹ PVP, 5 mg L⁻¹ casein, 3 mg L⁻¹ 6-benzyladenine (BA), and 0.1 mg L⁻¹ NAA, and the number of roots reached 18.8. The regenerated plants grown in a greenhouse had 100% survival following one week of hardening. Overall, our effective and efficient propagation method should result in shortened culture periods and reduced production costs, allowing for the future selective breeding and genetic improvement of A. pulcher.

Aluminum is an element found in nature and in cosmetic products. It can interfere with the metabolism of other cations, thus inducing gastrointestinal disorder. In cosmetics, aluminum is used in antiperspirants, lipsticks, and toothpastes. The aim of this work is to investigate aluminum bioavailability after accidental oral ingestion derived from the use of a toothpaste containing a greater amount of aluminum hydroxide than advised by the Scientific Committee on Consumer Safety (SCCS). To simulate in vitro toothpaste accidental ingestion, the INFOGEST model was employed, and the amount of aluminum was measured through the ICP-AES analysis. Tissue barrier integrity was analyzed by measuring transepithelial electric resistance, and the tissue architecture was checked through light microscopy. The margin of safety was also calculated. Overall, our results indicate that the acute exposure to aluminum accidentally ingested from toothpastes is safe for the final user, even in amounts higher than SCCS indications. Full article

This investigation is dedicated to unlocking the hidden potential of discarded cosmetics towards building green sustainable road pavements in the future. It is particularly aiming at exploring waste lipstick (WLS) as a high-quality functional additive for advanced asphalt mix technologies. To fuel this novel innovation, the effect of various WLS doses (e.g., 5, 10, and 15 wt.%) on the performance of base AP-5 asphalt cement was studied in detail. A wide array of cutting-edge analytical lab techniques was employed to inspect in-depth the physicochemical, microstructural, thermo-morphological, and rheological properties of resultant admixtures including: elemental analysis, Fourier transform-infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thin-layer chromatography-flame ionization detection (TLC-FID), scanning electron microscopy (SEM), atomic force microscopy (AFM), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), needle penetration, ring and ball softening point, Brookfield viscometer, ductility, and dynamic shear rheometer (DSR) tests. Unlike the unstable response of asphaltenes, the additive/artificial aging treatments increased the fraction of resins the most, and decreased that of aromatics; however, asphaltenes did not impair the saturates portion, according to Iatroscan research. FT-IR scan divulged that the WLS-asphalt interaction was physical rather than chemical. XRD diagnosis not only revealed an obvious correlation between the asphaltenes content and the fresh-binder crystallinity but also revealed the presence of fillers in the WLS, which may generate outstanding technical qualities to bituminous mixes. According to AFM/SEM analyses, the stepwise incorporation of WLS grew the magnitude of the “bee-shaped” microstructures and extended the roughness rate of unaged/aged binders. The prolonged consumption of the high thermal-stable additive caused a remarkable drop in the onset degradation and glass transition temperature of mixtures, thus enhancing their workability and low-temperature performance, according to TGA/DTGA/DSC data. The DSR and empirical rheological experiments demonstrated that the WLS could effectively lower the manufacturing and compaction temperatures of asphalt mixes and impart them with valuable anti-aging/fatigue-cracking assets. In a nutshell, the use of waste lipstick as an asphalt modifier is viable and cost-effective and could attenuate the pollution arisen from the beauty sector, while improving the performance of hot/warm asphalt mixes (HAM/WAM) and extending the service life of roadways.
