DILINOLEIC ACID/GLYCOL COPOLYMER.

Valuable CAS 68855-78-7 / FILM FORMING

This polymer functions as a multi-faceted ingredient, enhancing skin's barrier and texture. It delivers significant emollient benefits, forms a continuous, protective film, and improves product consistency, resulting in a smoothed, conditioned, and subtly glossy complexion, particularly beneficial for dry and itchy skin.

Summary

Emollient Film-forming Plasticizer Viscosity controlling

Science

Mechanism of Action

It operates by forming a substantive, continuous film on the skin's surface, effectively softening and smoothing its texture. This film acts as an occlusive barrier, reducing transepidermal water loss and enhancing skin hydration, while also contributing to formulation viscosity and providing a glossy finish. Its unique structure allows it to function as a rich emollient, often likened to a vegetable lanolin alternative.

Key findings

  1. 01 A clinical study demonstrated that topical application of an emollient containing this copolymer at 10% and 20% concentrations significantly improved skin dryness and reduced pruritus in patients with senile xerosis. Both concentrations increased skin conductance compared to an untreated group, with the 20% concentration showing superior improvements in dryness scores and skin conductance even when compared to white petrolatum.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically reviewed Dilinoleic Acid/Glycol Copolymer. However, related ingredients, Dialkyl Dimer Dilinoleates (containing dilinoleic acid), were found safe at concentrations up to 53%. Supplier-conducted Repeated Insult Patch Test (RIPT) results for the copolymer were favorable, indicating a low sensitization potential. Standard usage levels typically range from 1-5% in formulations.
