OLETH-15.

Valuable CAS 9004-98-2 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

OLETH-15 is a versatile nonionic surfactant that effectively emulsifies oils and water, facilitates cleansing, and helps dissolve insoluble ingredients in formulations. Crucially, it has been observed to enhance the skin's absorption of other active compounds.

Emulsifying agent Cleansing agent Solubilizing agent Surfactant Penetration enhancer

Science

Mechanism of Action

As a hydrophilic, ether-type nonionic surfactant, OLETH-15 primarily functions by reducing surface tension. This action allows it to emulsify oil and water components, aiding in the formation of stable emulsions, and to solubilize lipophilic substances into aqueous solutions. Additionally, its surfactant properties are noted to facilitate the penetration of other ingredients into the skin.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The CIR Expert Panel concludes OLETH-15 is safe under current practices of use and concentration when formulated to be non-irritating. However, it is explicitly advised against use on damaged skin due to theoretical risks associated with its parent compound, polyethylene glycol, observed in burn patients. Formulators must also account for its potential to increase the penetration of other ingredients into the skin.
