About HAIR KERATIN AMINO ACIDS
A protein hydrolysate derived from human hair that provides amino acids structurally similar to hair keratin for conditioning and repair benefits.
Detailed Analysis
Hair Keratin Amino Acids are obtained by the hydrolysis of human hair, yielding a mixture of amino acids (primarily cysteine, serine, glutamic acid, and glycine). These amino acids are the building blocks of keratin and can supplement damaged hair's protein structure. The ingredient is not restricted under EU Regulation (EC) No 1223/2009 for cosmetic use. The reference to 'ban substances that deplete the ozone layer' appears to be an erroneous restriction flag in the Cosing database, as keratin amino acids do not contain ozone-depleting substances. No CAS number is available for this specific ingredient.
