DIISOPROPYL DIMER DILINOLEATE.

Valuable CAS - / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

Diisopropyl Dimer Dilinoleate is an advanced emollient and skin-conditioning agent that enhances skin texture, prevents moisture loss, and contributes to epidermal health. It delivers a smooth, non-greasy feel and is broadly compatible with all skin types.

Summary

emollient skin conditioning lubricant dispersing agent

Science

Mechanism of Action

This ingredient functions by creating a protective barrier on the skin's surface, effectively preventing transepidermal water loss and restoring suppleness to dry, compromised skin. Its lubricating properties reduce flakiness and support a more intact epidermal cellular structure. Additionally, it aids in dispersing other formulation components like pigments and fragrances for uniform product application.

Research

Clinical Evidence

High confidence
Effective range 2–27%
Optimal

While specific optimal percentages vary by application, efficacy and safety have been demonstrated in formulations ranging from 2% to 27%.

Key findings

  1. 01 At 2%, makeup formulations were found to be non-acnegenic, non-comedogenic, and non-irritating.
  2. 02 A 5% concentration in a moisturizer formulation proved to be a dermal non-irritant.
  3. 03 Repeated-insult patch tests in lipstick formulations using concentrations of 10%, 18%, and 27% demonstrated no significant overall allergic responses, with only one mild, isolated reaction observed at 10%.
  4. 04 Clinical studies confirm that the highest concentration tested for irritation/sensitization (27%) did not produce skin irritation or sensitization.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed Diisopropyl Dimer Dilinoleate's safety for use in cosmetic products. Although direct irritation/sensitization testing reached 27%, the CIR panel concluded concentrations up to 53% are safe, citing the molecule's substantial size, lipophilic nature, insolubility in water, and the absence of reported significant allergic reactions. Animal studies further supported its non-irritating and non-comedogenic profile, with negative mutagenicity tests.
