KERATIN AMINO ACIDS
Keratin Amino Acids is a mixture of amino acids obtained through the complete hydrolysis of keratin. Rather than retaining keratin as a long protein chain, that process breaks it down into smaller units; the name therefore does not mean intact keratin or one single isolated amino acid.
KERATIN AMINO ACIDS: what it is
Keratin Amino Acids is a mixture of amino acids obtained through the complete hydrolysis of keratin. Rather than retaining keratin as a long protein chain, that process breaks it down into smaller units; the name therefore does not mean intact keratin or one single isolated amino acid.
Keratin is a group of structural proteins found in animal materials such as hair, wool, horn, hoof and nails. Cosmetic keratin derivatives can start from different raw materials, and the name Keratin Amino Acids on a label does not identify which one was used. This origin distinguishes the ingredient from plant proteins and from keratin derivatives that retain larger protein fragments.
KERATIN AMINO ACIDS: what it does in cosmetics
In hair products, Keratin Amino Acids is used for hair conditioning. In everyday terms, this function relates to the feel and appearance of the hair during and after use, as part of a formulation intended to make hair more pleasant to touch and manage.
It can also be used for skin conditioning, a cosmetic category concerned with maintaining the look and feel of the skin surface. Seeing the ingredient on a label is not a promise to repair damage, treat hair loss, promote growth or treat a skin condition; such claims would require direct evidence for the finished product and the intended use.
