Chlorphenesin ●
TL;DR. This ingredient is used as an antimicrobial preservative in water-containing formulas, with particular value for yeast and mold control. It is often paired with broader preservative systems rather than used as the only protection.
What does Chlorphenesin do in a cosmetic formula?
This ingredient is used as an antimicrobial preservative in water-containing formulas, with particular value for yeast and mold control. It is often paired with broader preservative systems rather than used as the only protection.
Is Chlorphenesin clean?
From a clean-beauty perspective, this ingredient has more friction than common food-grade organic acid preservatives because it is synthetic and halogenated. It can be acceptable in conventional formulas at regulated levels, but some clean standards and retailer lists restrict or exclude it.
Is Chlorphenesin sustainable?
This material is typically made from petrochemical feedstocks rather than renewable plant or mineral sources. Its synthetic halogenated structure creates more environmental scrutiny than readily biodegradable, bio-based preservative options.
Is Chlorphenesin COSMOS-approved?
It is not permitted under COSMOS-organic or COSMOS-natural standards as a cosmetic preservative. Its fit with Green Chemistry is limited because it relies on synthetic petrochemical chemistry and does not have the same renewable-feedstock profile as preferred COSMOS-aligned preservatives.
How does Chlorphenesin work chemically?
The molecule is a small synthetic aromatic ether-diol with a halogen substituent, giving it both water compatibility and antimicrobial membrane activity. Cosmetic use is commonly limited to about 0.3% in finished products, and it is usually co-formulated with other preservatives to broaden protection across bacteria, yeast, and mold.
