“…4 shows that after 7 min the system reached its steady-state viscosity. Also our previous research results with bentonite clays [1] confirm that in 10 min acrylate oligomer systems with clays recover its initial viscosity. This characteristic allows us to apply the coating on small surfaces without leakage and also helps to keep the pigments well dispersed in the system, decreasing agglomeration risk.…”

“…Ultraviolet (UV) curable films find increasing applications in coating industries because of their rapid cure, solvent-free characteristics, application versatility, low energy requirements, and low-temperature operation [1]. Depending on the final application, it is desirable to formulate polymer film systems with low shrinkage, high flexibility, decreased viscosity, good adhesion, and low sedimentation, and syneresis risk for pigmented systems [2,3].…”

“…These properties make nanoclay-reinforced polymers attractive in a number of coating applications, as well as in medicines and cosmetics. As coatings in cosmetics for natural nail aesthetic and protective function are mostly pigmented, the main value for nanoclay addition could be decrease in sedimentation and syneresis risk of pigments [1,2].…”

Increased interest in aesthetic, natural nail coatings has encouraged more in-depth studies, and particularly of ultraviolet curable coatings, their formation, processing, characteristics, and removal. This study investigated the impact of various thixotropic agents (organically modified hectorite and bentonite clays) on water-based oligomer system rheology. Ingredients were evaluated to determine their influence on unreacted composite characteristics (viscosity and pigment suspension stability) and reacted film characteristics (modulus of elasticity, elongation at break, and film adhesion force). It is concluded that clay-based thixotropic agents are suitable for use as a suspension agent in nail polish formulations and, depending on the concentration, can decrease the risk of pigment sedimentation and syneresis.

Clays and clay miner.

Clays are used in various cosmetic formulations, such as sunscreens, toothpastes, deodorants, creams, hair cosmetics, makeups, nail polish, facial masks, and shampoos, among others, to improve the organoleptic and physicochemical characteristics, to increase the stability, or to facilitate elaboration. Together with their technological functionalities, clays are cosmetologically active ingredients with cleaning, anti-aging, anti-wrinkling, and sun-care functionalities. Talc, kaolinite, mica, and some smectites are the clay minerals used most frequently in cosmetic products, but several other phyllosilicates as well as modified and synthetic clays are also used. Sometimes, clays are useful in the design of cosmetics just because they are made of rigid, small, and anisometric particles. Kaolinite and mica are made of hard prismatic particles which are lightly abrasive over the skin, teeth, or hair. Electric charges in smectites result in ion-exchange capacities useful in the loading of active cosmetics but also adsorbing and cleaning waste substances. Intermediate net negative charges of smectites result in layer expansion in polar media and specific rheological properties that are very useful in cosmetic formulations. The absence of charged particles in talc and kaolin make them flow easily resulting in lubricant effects. Protection against radiation from the sun by clay particles and decorative effects complete the possibilities of clays in cosmetics. The nomenclature for clays used as ingredients in cosmetics follows historical use and the names of commercial products, rather than following strict compositional principles. In this sense, an effort was made here to correlate the names of the minerals that make up each of the clay-based cosmetic ingredients.

This study provides an in-depth review of bentonite, focusing on its applications in Korea’s biomedical and cosmetic sectors. It delves into bentonite’s chemical properties, which make it a valuable resource in various industries, particularly in the health and beauty industries. We discuss bentonite’s antimicrobial properties, showcasing its effectiveness against a wide range of pathogens and its potential as a biomedicine adjuvant to boost immune responses. Despite its benefits, the review also addresses the need for caution due to its possible side effects when used in human therapy. In the cosmetics industry, bentonite is prized for its ability to absorb impurities, making it a popular ingredient in products from leading brands. The review highlights the ongoing research and development efforts aiming to further explore bentonite’s capabilities and applications, underlining the material’s significant contribution to advancing Korea’s innovation in the biomedical and cosmetic fields. This review suggests that with more research, bentonite’s full potential can be unlocked, offering new opportunities for these industries.
