Question 1

What does C12-14 Alketh-12 do in a cosmetic formula?

Accepted Answer

This ingredient is a nonionic surfactant, solubilizer, and emulsifier used to help disperse oils, fragrance components, and other hydrophobic materials in water-based formulas.

Question 2

Is C12-14 Alketh-12 clean?

Accepted Answer

From a clean-beauty perspective, it has friction because it is ethoxylated, a process associated with possible residual ethylene oxide and 1,4-dioxane if purification is not well controlled. It is generally considered functional and low-sensitizing, but many clean standards scrutinize or exclude this ingredient class.

Question 3

Is C12-14 Alketh-12 sustainable?

Accepted Answer

This material is typically made from fatty alcohol feedstocks combined with petrochemical-derived ethylene oxide, so its sourcing profile is mixed. The broader alcohol ethoxylate family is generally biodegradable, but the petrochemical processing step weakens its sustainability profile.

Question 4

Is C12-14 Alketh-12 COSMOS-approved?

Accepted Answer

It is not permitted under COSMOS-natural or COSMOS-organic standards because ethoxylated materials are outside the standard’s allowed chemistry. Its Green Chemistry fit is limited by petrochemical input and potential trace processing residues, despite useful performance at low levels and expected biodegradability.

Question 5

How does C12-14 Alketh-12 work chemically?

Accepted Answer

The molecule is a nonionic ether built from a C12 to C14 hydrophobic alkyl chain and an average of about 12 oxyethylene units, giving it water dispersibility and oil-solubilizing behavior. It is commonly used around 0.5% to 5% depending on whether the goal is solubilization, emulsification, or cleansing support, and it is usually stable across typical cosmetic pH ranges.
