Tyrosine ●
TL;DR. This ingredient is used mainly as a skin- and hair-conditioning amino acid. It can also appear in formulas positioned around radiance or tanning support because it participates in the body’s pigment pathway.
What does Tyrosine do in a cosmetic formula?
This ingredient is used mainly as a skin- and hair-conditioning amino acid. It can also appear in formulas positioned around radiance or tanning support because it participates in the body’s pigment pathway.
Is Tyrosine clean?
It is generally well tolerated and does not sit on common clean-beauty restricted lists. The main quality check is source and processing, rather than a major irritation or allergen concern.
Is Tyrosine sustainable?
This material is commonly made by fermentation or protein hydrolysis, with plant-based feedstocks possible. It is biodegradable and not known for environmental persistence in rinse-off or leave-on use.
Is Tyrosine COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic when produced from permitted natural feedstocks or fermentation and processed with allowed methods. Its profile fits Green Chemistry well because it can be bio-based, biodegradable, and functional at low levels.
How does Tyrosine work chemically?
The molecule is an aromatic amino acid with both amine and carboxyl groups plus a phenolic ring, making it a zwitterion around skin-relevant pH. It has limited water solubility at neutral pH, an isoelectric point near 5.7, and a phenolic pKa around 10, so formulators usually add it at low levels or use pH and solubilization strategy to keep it uniform.
