Science
Mechanism of Action
This ingredient significantly reduces the surface tension between immiscible phases, allowing for the stable blending of oils and water into cohesive emulsions. On the skin, its surfactant properties enable water to more readily mix with and remove oils and dirt, enhancing cleansing efficacy. Oleth-10 Phosphate also stabilizes formulations against delamination, solubilizes poorly soluble ingredients, and can facilitate increased penetration of other active compounds into the skin, while offering some moisturizing benefits.

Stability
Oleth-10 Phosphate demonstrates excellent stability within emulsions and clear microemulsions, effectively maintaining consistent product texture and preventing phase separation. It operates as a liquid, viscous oil-in-water emulsifier, with its water solubility generally improving with an increased content of ethylene oxide.

Safety
Safety Profile
The CIR Expert Panel has deemed Oleth ingredients, including Oleth-10, safe under current usage practices, with a recommended maximum concentration of 5%. However, it may induce mild to moderate eye and skin irritation; therefore, a patch test is advisable for sensitive individuals, and application on damaged skin should be avoided. A significant safety consideration is the potential for contamination with 1,4-dioxane, a carcinogenic byproduct, necessitating stringent purification during manufacturing. It also possesses the ability to enhance the dermal penetration of other ingredients within a formulation.
