What Phenoxyethanol does

Protects formulas from bacteria and mold
Keeps water-based products fresh longer
Works alongside other preservatives

Phenoxyethanol is made by chemical synthesis rather than taken from plants. Formulators add it to products that contain water, because water is where bacteria, yeast and mold can grow. A small amount is enough to keep a jar or bottle stable and safe to use over its shelf life, and it is often combined with other preservatives for broader coverage.

In its pure form it is a colorless liquid that blends smoothly into water-based formulas without making them greasy. It has a faint, mild scent, so it rarely changes how a product smells. It holds up well across many different recipes.

Good for

Suits everyday water-based products such as moisturizers, cleansers, sunscreens, body lotions and shampoos.

Be careful if

Nothing in particular for most skin types.

Frequently asked questions

Is phenoxyethanol safe to use on skin?

It is generally considered well tolerated and is used in many leave-on and rinse-off products. Some people with sensitive skin may notice mild redness or itching. If you are unsure, test a new product on a small patch of skin first, and stop using it if irritation develops.

Why is phenoxyethanol in so many moisturizers?

Moisturizers contain water, which can let bacteria, yeast and mold grow over time. Phenoxyethanol helps keep the product fresh from the first use to the last. Its mild feel and scent make it easy to use in everyday creams, lotions and cleansers.
