Science

Mechanism of Action

This ingredient operates by forming a subtle, protective film on the surface of the skin and hair. This film effectively minimizes transepidermal water loss, thereby sealing in moisture and preventing dehydration. Additionally, it functions as a solvent, which helps other ingredients integrate smoothly into a formulation.

Key findings

  1. 01 A related PPG Butyl Ether (PPG BE800, average molecular weight 800), when administered in feed to rats at concentrations between 0.001% and 0.26% over two years, exhibited no carcinogenic effects.
  2. 02 Clinical investigations on 200 subjects confirmed PPG BE800 to be non-irritating and non-sensitizing to the skin. Similarly, PPG-40 Butyl Ether, another related compound, showed no irritant or sensitizing potential in a repeat-insult patch test involving 112 subjects.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The CIR Expert Panel has deemed PPG-2 Butyl Ether, along with other PPG Butyl Ethers, safe for cosmetic use under the crucial condition that formulations are developed to prevent irritation. While human clinical data for related compounds indicated no significant skin irritation or sensitization, animal studies suggested a potential for irritation, necessitating the 'formulated to avoid irritation' caveat. Its use is permitted in cosmetics marketed within the European Union under general provisions.
