Phytosteryl Isostearyl Dimer Dilinoleate ●
TL;DR. This ingredient is a rich lipid emollient and skin-conditioning agent that adds cushion, gloss, adhesion, and water-resistant feel. It is especially useful in balms, lip products, makeup, and creams where a lanolin-like texture is wanted.
What does Phytosteryl Isostearyl Dimer Dilinoleate do in a cosmetic formula?
This ingredient is a rich lipid emollient and skin-conditioning agent that adds cushion, gloss, adhesion, and water-resistant feel. It is especially useful in balms, lip products, makeup, and creams where a lanolin-like texture is wanted.
Is Phytosteryl Isostearyl Dimer Dilinoleate clean?
From a clean-beauty perspective, it is generally well tolerated and has little restricted-list friction. Sensitization is not a common issue, although very rich ester materials can feel heavy for some users in leave-on facial products.
Is Phytosteryl Isostearyl Dimer Dilinoleate sustainable?
This material is usually made from plant-derived lipid feedstocks, including plant sterol fractions and vegetable fatty-acid streams. It is expected to be biodegradable as an ester, though its large, hydrophobic structure means it may break down more slowly than small, water-soluble ingredients.
Is Phytosteryl Isostearyl Dimer Dilinoleate COSMOS-approved?
It can be accepted under COSMOS-natural when supplied as a compliant natural-origin ester made with approved processing. It fits Green Chemistry reasonably well through renewable feedstocks and solvent-light ester chemistry, with the main caveat being its more processed, high-molecular-weight structure.
How does Phytosteryl Isostearyl Dimer Dilinoleate work chemically?
The molecule is a high-molecular-weight mixed ester built from plant sterol alcohols, branched C18 fatty alcohols, and a C36 fatty-acid it, giving it a viscous, adhesive, semi-occlusive skin feel. Typical use is about 1 to 10% in emulsions and anhydrous formulas, with higher levels possible in sticks, balms, and lip products; it is oil-soluble and broadly pH-stable because it sits in the oil phase.
