Cosmetic active ingredients are ingredients that are added to cosmetic formulations to provide specific benefits to the skin, hair, or nails. These ingredients are designed to improve the appearance, texture, and overall health of these areas. Some common cosmetic active ingredients and their CAS numbers are listed below:
1. Retinol (CAS no. 68-26-8): Retinol is a form of vitamin A that is used in anti-aging products to improve skin texture, reduce the appearance of fine lines and wrinkles, and promote skin cell turnover.
2. Salicylic acid (CAS no. 69-72-7): Salicylic acid is a beta-hydroxy acid (BHA) that is used to treat acne and exfoliate the skin. It works by unclogging pores and dissolving dead skin cells, which can lead to clearer, smoother skin.
3. Niacinamide (CAS no. 98-92-0): Niacinamide is a form of vitamin B3 that is used to improve skin texture, reduce the appearance of fine lines and wrinkles, and even out skin tone. It is also used to treat acne and rosacea.
4. Hyaluronic acid (CAS no. 9004-61-9): Hyaluronic acid is a natural component of the skin that helps to hydrate and plump the skin. It is used in anti-aging products to improve skin texture, reduce the appearance of fine lines and wrinkles, and promote a more youthful-looking complexion.
5. Alpha hydroxy acids (AHAs) (CAS no. varies): AHAs are a group of acids that are used to exfoliate the skin and promote cell turnover. They can help to reduce the appearance of fine lines and wrinkles, even out skin tone, and improve skin texture. Some common AHAs include glycolic acid, lactic acid, and mandelic acid.
6. Vitamin C (CAS no. 50-81-7): Vitamin C is a powerful antioxidant that is used to brighten the skin, even out skin tone, and promote collagen production. It can help to reduce the appearance of fine lines and wrinkles, and protect the skin from environmental damage.
7. Peptides (CAS no. varies): Peptides are small chains of amino acids that are used in anti-aging products to promote collagen production, improve skin texture, and reduce the appearance of fine lines and wrinkles. Some common peptides used in cosmetics include palmitoyl pentapeptide-4 and acetyl hexapeptide-8. These are just a few examples of the many active ingredients used in cosmetics. The use of these ingredients is regulated by various agencies, including the U.S. Food and Drug Administration (FDA) and the European Union's Cosmetics Regulation. It is important to note that not all cosmetic ingredients are safe or effective, and it is always recommended to consult with a dermatologist or other healthcare professional before using any new cosmetic product.
