Is Phenoxyethanol. May Contain: Bismuth Oxychloride COSMOS-approved?

Accepted Answer

It is not permitted in COSMOS-natural or COSMOS-organic certified finished products. From a Green Chemistry view, it has useful efficacy at low dose and biodegrades, but its synthetic petrochemical origin and limited certification alignment keep it from a green rating.

Question 5

How does Phenoxyethanol. May Contain: Bismuth Oxychloride work chemically?

Accepted Answer

The molecule is an aromatic ether alcohol with both water and oil compatibility, which helps it partition into microbial membranes while remaining usable in emulsions and gels. Typical use is about 0.5 to 1.0%, with regulatory maximums commonly set at 1.0%, and it is stable across a broad pH range and during normal cosmetic processing temperatures.
