Ceteareth-15 Glyceryl Stearate ●
TL;DR. This ingredient is a nonionic oil-in-water emulsifier and consistency aid, helping blend oils and waxes with water while improving cream stability and texture.
What does Ceteareth-15 Glyceryl Stearate do in a cosmetic formula?
This ingredient is a nonionic oil-in-water emulsifier and consistency aid, helping blend oils and waxes with water while improving cream stability and texture.
Is Ceteareth-15 Glyceryl Stearate clean?
It is usually well tolerated on skin, but clean-beauty frameworks often flag it because it is made through ethoxylation and can carry trace 1,4-dioxane if purification is poor. Stricter programs typically expect supplier documentation and residual testing.
Is Ceteareth-15 Glyceryl Stearate sustainable?
It combines fatty-derived portions, often plant-based, with petrochemical-derived segments. Biodegradability is less favorable than simpler natural emulsifiers, and sourcing quality can depend on the fatty feedstock, including palm-linked supply chains.
Is Ceteareth-15 Glyceryl Stearate COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic because the manufacturing route uses ethoxylation, which sits outside the standard’s allowed chemistry. From a Green Chemistry view, the main friction points are petrochemical input, residual-processing controls, and weaker biodegradability than non-ethoxylated fatty emulsifiers.
How does Ceteareth-15 Glyceryl Stearate work chemically?
The molecule is a blended nonionic emulsifier built from fatty ester chemistry plus water-loving polyoxyethylene segments, giving it amphiphilic behavior for oil-in-water systems. Typical use is about 1; 5% in creams and lotions, often alongside fatty alcohols or waxes, and it generally performs across mildly acidic to neutral skin-care pH.
