Question 1

What does Beheneth-30 do in a cosmetic formula?

Accepted Answer

This ingredient is a nonionic emulsifier and solubilizer that helps disperse oils, waxes, and fragrance components in water-based formulas. It can also support cream structure and improve rinse-off texture.

Question 2

Is Beheneth-30 clean?

Accepted Answer

From a clean-beauty perspective, it is flagged mainly because it is made by ethoxylation, a process that can leave trace residues such as 1,4-dioxane if not well purified. Finished cosmetic grades are typically refined and monitored, but many clean standards restrict or disallow this class.

Question 3

Is Beheneth-30 sustainable?

Accepted Answer

It combines a long-chain fatty component that may be plant-derived with ethoxylate units typically from petrochemical feedstocks. This class is generally biodegradable, but manufacturing depends on a high-reactivity gas and residue controls.

Question 4

Is Beheneth-30 COSMOS-approved?

Accepted Answer

It is generally not permitted under COSMOS-natural or COSMOS-organic because ethoxylated materials are outside the standard’s allowed processing chemistry. Its Green Chemistry fit is mixed: effective at low use levels and often biodegradable, but it depends on petrochemical input and a less-preferred reaction route.

Question 5

How does Beheneth-30 work chemically?

Accepted Answer

The molecule is a nonionic surfactant made from a C22 fatty alcohol backbone capped with about 30 ethoxy units, giving it high hydrophilicity and strong oil-in-water emulsifying capacity. It is commonly used at roughly 0.5–5% in emulsions or solubilizing systems, is stable across typical cosmetic pH ranges, and can be paired with fatty alcohols, waxes, and co-emulsifiers to tune viscosity and lamellar gel structure.
