Phenoxyethanol

The preservative in most of our water-containing products. Synthetic, used at under 1%, and the reason a bottle of aloe and botanicals does not grow mould on your shelf.

Role

Preservative that keeps water-based formulas safe

Best for

Any product that contains water

What it does

Anything with water in it, including aloe juice, flaxseed gel and most leave-ins, will grow bacteria and mould within days unless it is preserved. Phenoxyethanol is a broad-spectrum preservative that works across a wide pH range and does not release formaldehyde. The European Commission's Scientific Committee on Consumer Safety reviewed it in 2016 and concluded it is safe for all consumers, including children, at the EU maximum of 1%.

We would rather tell you this plainly than hide behind the word "natural". A preservative-free water-based product is not safer; it is a petri dish. Oil-only products (no water) do not need one, and ours do not contain one.

How we use it

At well under 1% in every water-based formula, named on the label. Anhydrous oils and butters are preservative-free.
