Mechanism of Action
By lowering interfacial tension, C9-11 PARETH-40 facilitates the creation of stable oil-in-water (O/W) emulsions. Its high Hydrophilic-Lipophilic Balance (HLB) value of approximately 18 makes it particularly adept at solubilizing lipophilic substances into aqueous solutions while maintaining formulation clarity and texture.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 In vivo dermal toxicity evaluations at high concentrations (25%) showed localized epidermal changes without systemic toxicity, suggesting a high safety margin.
- 02 Human clinical trials using analogous structures at concentrations up to 5% confirmed a low potential for both irritation and sensitization.
- 03 Mutagenicity assessments via the Ames test returned negative results, confirming the ingredient is non-genotoxic.

Dusting Analysis
As a functional stabilizer rather than an active 'hero' ingredient, it is rarely 'dusted' for marketing purposes; however, concentrations below 0.1% may be insufficient for stabilizing complex fragrance or oil loads.
The Formula
Formulation
Stability
Exhibits exceptional stability across a wide pH spectrum and remains active in hard water or high-salt environments.
Synergies
- Lipophilic vitamins
- Essential oils
- Fragrance compounds
Conflicts
- Strong oxidizing agents
Safety
Safety Profile
Safe for cosmetic use provided the final formulation is engineered to be non-irritating, a standard met by high-HLB surfactants in this class.
