Amino acids used in cosmetics can be derived from both animals and plants. You will have to read to read the fine prints, look for vegan stamps, or ask the manufacturer to know if the highlighted ingredient is sources from animal biological parts.

Amino acids can for example be sourced from egg albumen, casein (milk/cheese), urine, or various animal hairs.

The organization People for the Ethical Treatment of Animals (PETA) has included amino acids on their Animal-derived Ingredients List.

Amino acids include for example tyrosine, cystine, glycine, and many more. Polypeptide, which also can be found as an ingredient in cosmetic products, is a string of amino acids that are linked together that may be derived from animal protein.

How is it used?

Amino acids can be found naturally in all kinds of foods, and as nutritional supplements and vitamins.

In cosmetics*, they are known to function as emollients (softens and smoothes skin and hair) and can be found in products such as creams and hair care products.

We use the European Commissions definition of Cosmetics:
“Cosmetics range from everyday hygiene products such as soap, shampoo, deodorant, and toothpaste to luxury beauty items including perfumes and makeup”.
