Question 1

What does Phenoxyethanol[2] do in a cosmetic formula?

Accepted Answer

This ingredient is a broad-spectrum preservative, used mainly to protect water-containing formulas from bacterial growth. It is often paired with other preservative boosters to cover yeast and mold more completely.

Question 2

Is Phenoxyethanol[2] clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is accepted by many conventional and retailer clean standards but still has some friction because it is synthetic and can irritate sensitive skin at higher levels. In the EU, it is capped at 1% in cosmetics, which is also the common upper use limit globally.

Question 3

Is Phenoxyethanol[2] sustainable?

Accepted Answer

This material is typically made from petrochemical feedstocks, so its sourcing is not renewable in most supply chains. It is considered readily biodegradable and is not known as a highly persistent cosmetic ingredient.

Question 4

Is Phenoxyethanol[2] COSMOS-approved?

Accepted Answer

This ingredient is generally not permitted in COSMOS-natural or COSMOS-organic certified finished products. Its Green Chemistry profile is mixed, with effective low-dose preservation and good biodegradability, but mainly petrochemical sourcing and ethoxylation-linked manufacture.

Question 5

How does Phenoxyethanol[2] work chemically?

Accepted Answer

The molecule is an aromatic ether alcohol, which gives it both oil and water compatibility and helps it partition into microbial membranes. It is typically used at 0.5% to 1.0%, performs across a broad pH range, and is commonly combined with chelators, organic acids, or preservative boosters for broader system coverage.
