PEG/PPG-10/3 OLEYL ETHER DIMETHICONE.

Valuable CAS - / EMULSION STABILISING, HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A silicone-based emulsifier and skin conditioning agent, PEG/PPG-10/3 Oleyl Ether Dimethicone creates a protective barrier on the skin, enhancing hydration and imparting a smooth, silky feel. It also functions to stabilize cosmetic formulations by enabling the uniform blending of oil and water phases.

Science

Mechanism of Action

This silicone derivative operates as a multifaceted ingredient. It functions as an emulsifier and emulsion stabilizer, facilitating the creation and maintenance of stable, finely dispersed oil-in-water mixtures. On the skin, it forms a protective barrier, effectively reducing transepidermal water loss (TEWL) and contributing to enhanced skin hydration. Its structure provides emolliency, imparts a desirable silky texture, and has the potential to extend the release of active ingredients for prolonged benefit.

Key findings

  1. 01 Clinical studies involving Dimethicone Copolyol, an umbrella term encompassing PEG/PPG-10/3 Oleyl Ether Dimethicone, demonstrated no primary skin irritation when applied in a 40% aqueous solution on 39 subjects.
  2. 02 Further evaluations confirmed undiluted Dimethicone Copolyol to be non-irritating on 39 subjects and non-sensitizing on 50 subjects.
  3. 03 Comprehensive testing on 201 volunteers also supported the non-irritating and non-sensitizing profile of Dimethicone Copolyol across various applications.

The Cosmetic Ingredient Review (CIR) Expert Panel assessed Dimethicone Copolyol, including this ingredient, as 'safe as used' in 1982, reaffirming this assessment in 2005 and 2013/2014. Its high molecular weight limits significant absorption into the skin or scalp. The US FDA considers it safe at low concentrations for skin protection. Generally, dimethicone-based compounds are not associated with comedogenicity, and it has been confirmed as neither a primary skin nor ocular irritant or sensitizer.
