Health Effects of Dyes, Minerals, and Vitamins Used in Cosmetics

Abstract

The average woman uses 12 different cosmetic products every day, but they can have a negative effect on human health. Therefore, in recent years, consumer preferences have changed towards buying natural or ecological cosmetics free from preservatives or unnecessary dyes. The aim of this work is to discuss the use of dyes, minerals, and vitamins in cosmetics in terms of their safety and impact on human health. These substances are very important in the cosmetics industry. Most of them are of natural origin. Some minerals used in the production of face masks or creams are recommended to work against inflammations such as ulcers and acne. Clay minerals have exceptional qualities, among others, low or no toxicity and high bio-compatibility. However, some of them may be harmful. For example, the safety of using talc has been widely debated in recent years. Cosmetic-grade talc cannot contain detectable fibrous asbestos minerals. Moreover, talc should not be applied to the skin when the epidermal barrier is missing or significantly disrupted. The use of talc in cosmetic products in the European Union is restricted. Vitamins are one of the most commonly used, biologically active, and easily accessible components in cosmetics. For example, provitamin B5 (D-panthenol) is a bioactive substance. In cosmetic preparations, it has a softening, repairing, and anti-inflammatory effect and is responsible for regulating sebum secretion. However, some vitamins may be harmful to human health. For example, the use of skin-whitening cosmetics containing vitamin C causes allergic contact dermatitis, whereas the most common adverse effect of topical use of vitamin A is skin irritation, erythema, and peeling. Dyes, which are used to color cosmetics, do not improve the condition of the skin, hair, or nails. Some of them may be harmful to human health. For example, the dye CI 60730 (Acid Violet 43) is prohibited for use in eye products and cosmetics that have contact with mucous membranes. In conclusion, some of the popular cosmetic ingredients discussed in this paper may exert a negative influence on human health, and many of these harmful effects have been discovered recently. Therefore, there is a need for further studies on the possible negative effects of dyes, minerals, and vitamins used in cosmetic products.

Enhancement of Mechanical Properties in Glass-Fiber Woven Reinforced Hybrid Composites for Aerospace Applications: An Empirical Investigation

“…In the realm of improving the mechanical properties of thermoplastics, e-GF reinforcements are a viable alternative when surface-treated fibers are employed because of their high mechanical qualities and enhanced fiber-PM adhesion [16]. Furthermore, kaolin clay, which is mostly constituted of hydrated aluminium silicate minerals (primarily kaolinite) with trace amounts of other oxides, is an important filler material in composite applications [17][18][19][20]. Another notable innovation is hybrid composites (HCs), which combine various reinforcing types within the same matrix to synergize composite features [21].…”

Optimization of Carboniferous Egyptian Kaolin Treatment for Pharmaceutical Applications

“…In this regard, the present study robustly recommends the further treatment optimization of clay minerals for medicinal use, such as montmorillonite, saponite, vermiculite, halloysite, sepiolite, and palygorskite. Although clay minerals rank as the most adequately studied natural minerals in the healthcare field, they still continue to present a critical challenge in pharmaceutics and biomedicine with regard to their grade and their elemental impurities [1,56]. Undoubtedly, there are several huge clay deposits around the world that are of economic importance.…”

Content and stability of B complex vitamins in commercial cosmetic products

“…Pyridoxine has been recently found to specifically increase filaggrin transcription and production in the skin, making it a candidate for the treatment of atopic dermatitis 5 . Biotin acts as a hair and skin‐conditioning (miscellaneous) agent and is thus commonly found in hair conditioners and masks as well as skincare products 1,6 . Folic acid is an upcoming agent in the treatment of photodamaged and aged skin due to its involvement in cell replication, regulation of gene activity, and skin renewal 7 .…”

“…Thiamin and riboflavin are used in the treatment of rosacea and seborrheic diseases, due to the antipruritic effect of thiamine and the anti‐inflammatory effect of riboflavin. 1 Because of the various beneficial effects on the skin, niacin in the form of nicotinamide is widely used as the (cosmetically) active ingredient in cosmetic and dermatological formulations. Nicotinamide has anti‐microbial, anti‐inflammatory, antipruritic, vasoactive, lightening, barrier‐ and photo‐protective, and sebostatic effects on the skin.…”
