Peg-11 Methyl Ether Dimethicone ●
TL;DR. This ingredient is primarily used as a conditioning and slip agent, and it can also act as a co-emulsifier that helps oil-rich systems spread evenly and disperse pigments.
What does Peg-11 Methyl Ether Dimethicone do in a cosmetic formula?
This ingredient is primarily used as a conditioning and slip agent, and it can also act as a co-emulsifier that helps oil-rich systems spread evenly and disperse pigments.
Is Peg-11 Methyl Ether Dimethicone clean?
Clean-beauty frameworks often flag it because it combines a persistent synthetic organosilicon backbone with ethoxylated segments, which require residue controls for 1,4-dioxane and ethylene oxide. It is usually low in direct irritation, but it has more restricted-list friction than simpler fatty alcohols or plant-derived emulsifiers.
Is Peg-11 Methyl Ether Dimethicone sustainable?
This material comes from mineral silicon chemistry combined with petrochemical processing, rather than a renewable agricultural feedstock. It is not readily biodegradable, so persistence in wastewater and sediment is the main environmental concern.
Is Peg-11 Methyl Ether Dimethicone COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic because synthetic organosilicon polymers and ethoxylated materials fall outside the standard’s allowed chemistry. From a Green Chemistry lens, it scores weakly on renewable feedstock and biodegradability, even though it can deliver formulation effects at low use levels.
How does Peg-11 Methyl Ether Dimethicone work chemically?
The molecule is an amphiphilic comb polymer, with a hydrophobic organosiloxane backbone and pendant ethoxylated methyl-it chains that improve compatibility between oil-rich phases and water. Typical use is often about 0.5 to 5% as a co-emulsifier or sensory additive, with good pH stability across normal cosmetic ranges and quality control focused on residual ethoxylation byproducts.
