Question 1

What does Phenoxyethanol. [+/- : CI 77491/77492/77499 do in a cosmetic formula?

Accepted Answer

This ingredient is a broad-spectrum preservative used to protect water-containing formulas from microbial growth. It is especially common in emulsions, serums, cleansers, and wipes, often paired with boosters for broader coverage.

Question 2

Is Phenoxyethanol. [+/- : CI 77491/77492/77499 clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is accepted by many conventional safety frameworks but often restricted or excluded by stricter clean standards. The main friction points are synthetic origin, use-level limits, and occasional irritation or sensitization reports, especially around the eye area or in compromised skin.

Question 3

Is Phenoxyethanol. [+/- : CI 77491/77492/77499 sustainable?

Accepted Answer

This material is usually made from petrochemical feedstocks, which gives it a weaker renewable-sourcing profile. It is considered readily biodegradable and is not known as a major persistence or bioaccumulation concern at cosmetic use levels.

Question 4

Is Phenoxyethanol. [+/- : CI 77491/77492/77499 COSMOS-approved?

Accepted Answer

It is not permitted in COSMOS-natural or COSMOS-organic certified formulas, despite being allowed in many mainstream cosmetic regulations up to defined limits. Its Green Chemistry profile is mixed, with effective low-dose preservation and biodegradability, but nonrenewable feedstocks and conventional synthesis reduce alignment.

Question 5

How does Phenoxyethanol. [+/- : CI 77491/77492/77499 work chemically?

Accepted Answer

The molecule is an aromatic ether alcohol, which gives it enough water compatibility to function in the aqueous phase while retaining affinity for microbial membranes. It is commonly used up to 1.0 percent, performs across a broad pH range, and is frequently combined with organic acids, chelators, or booster molecules to improve preservation robustness.
