DIMETHICONE PEG-7 PHOSPHATE ●
TL;DR. This ingredient is primarily a surfactant and emulsifier that helps disperse oils, pigments, and sunscreen filters in water-containing formulas. It can also add slip, reduce tack, and improve wet combing or skin feel.
What does DIMETHICONE PEG-7 PHOSPHATE do in a cosmetic formula?
This ingredient is primarily a surfactant and emulsifier that helps disperse oils, pigments, and sunscreen filters in water-containing formulas. It can also add slip, reduce tack, and improve wet combing or skin feel.
Is DIMETHICONE PEG-7 PHOSPHATE clean?
From a clean-beauty perspective, it carries friction because it combines a synthetic organosiloxane backbone with ethoxylated segments, which many standards scrutinize for persistence and possible trace ethoxylation residues. It is not a common contact allergen, but it is not a simple clean-standard fit.
Is DIMETHICONE PEG-7 PHOSPHATE sustainable?
This material is synthetic and typically relies on mineral-derived silicon chemistry plus petrochemical ethoxylation inputs rather than renewable plant feedstocks. Its organosiloxane portion is expected to biodegrade slowly, so persistence is the main environmental concern.
Is DIMETHICONE PEG-7 PHOSPHATE COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic because silicone-derived and ethoxylated materials sit outside the standard. Its Green Chemistry profile is limited by nonrenewable feedstocks, slow biodegradation, and more complex synthetic processing.
How does DIMETHICONE PEG-7 PHOSPHATE work chemically?
The molecule is an amphiphilic it ester with an organosiloxane segment and about seven oxyethylene units, giving it both oil affinity and water dispersibility. It is generally used at low single-digit percentages, and its anionic it group can be sensitive to high electrolyte loads or strongly cationic co-ingredients.
