Science
Mechanism of Action
This ingredient forms a protective, non-occlusive film on the skin's surface after application. This film contributes to improved product adherence and wear, and can enhance properties like water resistance and the spreading of UV protection components.

Stability
Specific pH stability data for Ricinoleoyl Epoxy Resin within cosmetic formulations is not extensively documented. However, general epoxy groups typically undergo curing reactions under alkaline conditions, with optimal pH ranges between 8.5-13, specifically 9-10 for amines and 13 for hydroxyl groups.
Conflicts
- Strong nucleophiles (e.g., primary amines, thiols) if unreacted epoxy groups are present, as these can initiate nucleophilic substitution reactions.
Safety
Safety Profile
Ricinoleoyl Epoxy Resin lacks a dedicated safety assessment from regulatory bodies such as the CIR or SCCS. While uncured epoxy resins are known irritants and sensitizers, potentially causing allergic contact dermatitis, fully cured epoxy resins are generally considered non-irritating and non-sensitizing. The safety of this cosmetic derivative in a finished product is highly dependent on its specific formulation and whether all epoxy groups have fully reacted.
