OLETH-106.

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

OLETH-106 is a highly water-soluble surfactant, characterized by 106 ethylene oxide units, primarily functioning as an emulsifier, solubilizer, and cleansing agent in skincare formulations. It stabilizes diverse product types, aiding in ingredient dispersion and impurity removal, with a potential for mild moisturizing benefits.

surfactant emulsifier solubilizer cleansing agent product stabilizer

Science

Mechanism of Action

OLETH-106 operates by significantly lowering surface tension, facilitating the stable blending of immiscible phases such as oil and water into emulsions. Its solubilizing capacity enables the dissolution of lipophilic or sparingly soluble ingredients within aqueous systems. As a cleansing agent, it helps water encapsulate and rinse away oil and dirt from the skin, while also contributing to overall product stability and potentially offering a degree of skin hydration.

Stability

OLETH-106 is highly water-soluble due to its extensive ethoxylation, improving product stability. While specific pH stability for OLETH-106 is not definitively stated, related Oleth compounds show variable pH sensitivity, with some indicating hydrolysis at high pH. It is generally incompatible with strong bases at elevated temperatures, strong acids, strong oxidizing agents, and materials containing reactive hydroxyl compounds.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed OLETH-106 as safe for cosmetic use when formulated to be non-irritating. However, it carries a risk of mild to moderate eye and skin irritation. Importantly, OLETH-106 should not be applied to damaged skin, a restriction also applicable to polyethylene glycols. Formulators must also consider its potential to enhance the penetration of other ingredients. A manufacturing concern is the possible presence of 1,4-dioxane if purification during its production is inadequate.

Verdict

Valuable

OLETH-106 is a valuable multi-functional surfactant that enhances product stability and ingredient dispersion, though formulation care is required to mitigate potential irritation and address 1,4-dioxane concerns.
