About
Ceteareth-20 — an ethoxylated fatty alcohol that emulsifies oil and water in creams. Reliable workhorse with CIR safety review; the only genuine caveat is 1,4-dioxane traces, which reputable suppliers strip to negligible levels.
Skin benefits
- Effective oil-in-water emulsifier for creams and lotions
- Solubilises lipophilic actives for delivery
- Good cosmetic stability and skin feel
Known concerns
- Ethoxylated material can carry residual 1,4-dioxane unless purified
- Mild irritation possible at higher use levels
- Not appropriate for compromised barrier skin
