Science
Mechanism of Action
This polymer forms an ultra-thin, non-occlusive film that prevents trans-epidermal water loss (TEWL) without suffocating the skin. It acts as a structural reinforcement agent in stick-form products, ensuring uniform pigment distribution and reducing the inherent tackiness of other emollient ingredients.

Key findings
- 01 Human Repeat Insult Patch Testing (HRIPT) of related silsesquioxane structures at 4.337% demonstrated zero adverse events, confirming its status as a non-sensitizer.
- 02 Safety assessments of the broader ingredient family at concentrations up to 22% showed a 0% incidence of skin sensitization.
