Science
Mechanism of Action
As a surfactant, OLETH-7 reduces the surface tension between different phases, enabling water to effectively mix with oils and impurities, allowing them to be rinsed away from the skin. Its emulsifying properties are crucial for creating stable oil-in-water formulations, preventing phase separation. Furthermore, it acts as a solubilizer, helping to dissolve hydrophobic ingredients in aqueous systems, enhancing product clarity and uniformity.

Stability
The water solubility of Oleth ingredients generally increases with a higher content of ethylene oxide. Related compounds like Oleth-10 exhibit good water solubility and high HLB values, suggesting similar efficacy for OLETH-7 as an emulsifier in oil-in-water systems.
Conflicts
- Should not be applied to damaged or compromised skin due to potential systemic absorption, as observed with related polyethylene glycol compounds on burn patients leading to kidney effects.
- Formulators must be aware that OLETH-7 may enhance the skin penetration of other ingredients, necessitating careful consideration of overall formulation.
Safety
Safety Profile
The CIR Expert Panel considers Oleth ingredients, including OLETH-7, safe for cosmetic use when formulated to be non-irritating. However, evidence of mild to moderate eye and skin irritation has been noted. A significant restriction involves avoiding its use on damaged skin. Trace amounts of 1,4-dioxane, a by-product of ethoxylation, may be present but can be controlled through purification processes.

Verdict
OLETH-7 is a valuable functional ingredient for formulating stable and effective cosmetic products, acting as an emulsifier and solubilizer, provided its use is restricted to intact skin and the formulation ensures non-irritating properties.
