DIMER DILINOLEATE/ETHYLENEDIAMINE COPOLYMER ACETATE.

Valuable CAS - / FILM FORMING

This ingredient functions as a film-forming agent, creating a protective layer on the skin's surface. This action supports the skin barrier, aids in moisture retention, and contributes to a smoother skin texture.

Summary

Film-forming Moisturizing Barrier strengthening Emulsifying Elasticity maintenance Smoothness enhancement

Science

Mechanism of Action

DIMER DILINOLEATE/ETHYLENEDIAMINE COPOLYMER ACETATE operates by forming a resilient, breathable film upon topical application. This physical barrier reinforces the skin's natural defense system, actively minimizing transepidermal water loss (TEWL) and offering protection from external environmental factors. Additionally, this film contributes to maintaining skin elasticity and imparting a sensation of smoothness.

Key findings

  1. 01 Clinical evaluations of related Dialkyl Dimer Dilinoleates demonstrated that cosmetic formulations, including moisturizers containing 5% Diisopropyl Dimer Dilinoleate and makeup formulations with 2% Diisopropyl Dimer Dilinoleate, did not induce skin irritation, sensitization, or comedogenicity. While a 10% concentration of Diisostearyl Dimer Dilinoleate was noted to cause very minor irritation, the overall body of evidence for related compounds suggests a low potential for adverse dermal reactions.
