Science
Mechanism of Action
This ingredient functions by reducing interfacial tension between immiscible phases, allowing for the creation of stable emulsions. As a polar molecule, it aligns itself at the oil-water interface to prevent droplet coalescence and, when used in cleansing systems, assists in the solubilization and removal of lipophilic impurities from the skin and hair.

Dusting Analysis
As a functional additive rather than a primary bioactive, this ingredient is typically used at concentrations required for structural stability of the formula rather than for marketing claims.
The Formula
Formulation
Stability
Demonstrates excellent stability across various pH ranges in specific applications like hair dyes, though its parent compound, Oleth-5, may be susceptible to hydrolysis in highly alkaline environments.
Safety
Safety Profile
The CIR Expert Panel considers it safe when formulated to be non-irritating, though it should be avoided on compromised or damaged skin. While historical NTP studies on DEA-related compounds raised animal-based concerns, no human carcinogenic risk has been established, and current industry usage is declining.
