Science
Mechanism of Action
Functions as a potent O/W (oil-in-water) emulsifier by reducing interfacial tension at the phase boundary. It aligns itself to stabilize droplets within a formula while simultaneously acting as an occlusive agent that minimizes transepidermal water loss (TEWL).

Key findings
- 01 Safety assessments of related PEG ethers confirm minimal irritation potential in 21-day patch testing and no evidence of sensitization.
- 02 Margin of Safety (MoS) calculations confirm a satisfactory safety profile for high-use leave-on applications like anti-cellulite and moisturizing creams.

Dusting Analysis
As a functional ingredient rather than a primary active, it is rarely 'dusted' for marketing purposes. It is typically included at concentrations between 1% and 5% to ensure formula integrity.
The Formula
Formulation
Stability
Possesses a high HLB value of 16.0-16.3, making it ideal for stabilizing oil-in-water emulsions; sensitive to extreme alkaline environments which may trigger hydrolysis.
Synergies
- Lipophilic co-emulsifiers
- Humectants
- Fatty alcohols
Conflicts
- Strong oxidizing agents
- Highly damaged skin barriers
Safety
Safety Profile
Contraindicated for use on severely damaged or burned skin due to potential nephrotoxicity risks associated with PEG-based ingredients in compromised systemic states.
