CHLORPHENSIN ●
TL;DR. This ingredient functions mainly as an antimicrobial preservative, helping limit microbial growth in water-containing cosmetics and personal care formulas. It is also sometimes used as a preservative booster in systems built around other antimicrobials.
What does CHLORPHENSIN do in a cosmetic formula?
This ingredient functions mainly as an antimicrobial preservative, helping limit microbial growth in water-containing cosmetics and personal care formulas. It is also sometimes used as a preservative booster in systems built around other antimicrobials.
Is CHLORPHENSIN clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic chlorinated preservative and is not widely accepted by stricter natural or organic standards. It is legally used at low levels, but sensitive skin may react to it, especially in leave-on products.
Is CHLORPHENSIN sustainable?
This material is typically petrochemical-derived rather than plant-derived. Its chlorinated aromatic structure is a weaker sustainability fit than readily biodegradable, renewable preservative options, and environmental data are not as reassuring as for simpler food-grade acids and alcohols.
Is CHLORPHENSIN COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards as a cosmetic preservative. Its synthetic origin and halogenated structure place it in poor alignment with Green Chemistry preferences for renewable feedstocks, ready biodegradability, and simpler end-of-life profiles.
How does CHLORPHENSIN work chemically?
The molecule is a small chlorinated aromatic ether with two alcohol groups, which gives it moderate water compatibility and antimicrobial activity in aqueous formulas. Typical cosmetic use is up to about 0.3%, and it is commonly paired with other preservatives to broaden coverage across bacteria, yeast, and mold.
