Science
Mechanism of Action
Cetoleth-4 acts as a bridge between oil and water phases to maintain product homogeneity. On the skin, it functions as a penetration enhancer by momentarily reorganizing the lipid structure of the stratum corneum, facilitating deeper delivery of co-formulated nutrients.

Key findings
- 01 Safety evaluations by the Cosmetic Ingredient Review (CIR) confirm that concentrations up to 5% are non-sensitizing and non-irritating in leave-on applications.
- 02 Studies published in the International Journal of Toxicology indicate that while pure forms can be reactive, typical cosmetic dilutions show no evidence of being primary irritants.

Dusting Analysis
As a functional emulsifier, it is rarely 'dusted' for marketing purposes; its presence is usually strictly tied to the structural integrity and delivery efficiency of the formula.
