PEG/PPG-30/10 DIMETHICONE.

Valuable / SURFACTANT - EMULSIFYING

PEG/PPG-30/10 Dimethicone is a sophisticated alkoxylated silicone polymer engineered to enhance formulation stability and optimize skin feel. It acts as a versatile emulsifier and surfactant, facilitating uniform blending of diverse ingredients while imparting conditioning benefits.

Science

Mechanism of Action

This alkoxylated dimethicone derivative primarily functions by reducing surface tension, making it an effective surfactant and emulsifying agent crucial for stable formulations. On the skin, it forms a lightweight, uniform film that significantly improves tactile smoothness and provides a protective barrier, which can help prevent moisture loss and enhance overall skin comfort.

Key findings

  1. 01 Dimethicone Copolyol, a class encompassing PEG/PPG-30/10 Dimethicone, was clinically demonstrated not to be a primary skin irritant when tested at concentrations up to 40% in aqueous solutions.
  2. 02 Further testing confirmed that undiluted Dimethicone Copolyol, including PEG/PPG-30/10 Dimethicone, also exhibited no primary skin irritancy.
  3. 03 In a study involving 201 volunteers, Dimethicone Copolyol proved to be non-irritating and non-sensitizing.

Stability

This ingredient demonstrates robust stability against hydrolysis and maintains its efficacy across a wide pH spectrum, rendering its pH value 'not applicable' for stability considerations. Its amphiphilic character enables it to effectively solubilize low viscosity silicone fluids within aqueous-based formulations, promoting formulation versatility.

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that 'dimethicone copolyol,' an umbrella term for ingredients including PEG/PPG-30/10 Dimethicone, is 'safe as used' in 1982, a finding reaffirmed in 2005. Although a 2014 report noted 'insufficient data' for 111 related ingredients (specifically requesting more molecular weight details), this did not alter the broader 'safe as used' determination for dimethicone copolyols. Clinical studies confirm no primary skin irritation at concentrations up to 100%.
