Science
Mechanism of Action
Hypothesized to follow L-Cystine's mechanisms, which include acting as a glutathione precursor for antioxidant defense, influencing melanin synthesis towards lighter pheomelanin, and supporting keratinocyte viability. The impact of the dicapryloyl modification on these actions remains to be fully elucidated.

Stability
The optimal pH range for DICAPRYLOYL CYSTINE stability is not specified. Its parent, L-Cystine, shows low solubility at neutral pH, becoming more soluble under highly acidic (pH < 2) or alkaline (pH > 8) conditions; the dicapryloyl groups would likely alter these properties.
Safety
Safety Profile
No specific safety assessments (CIR, SCCS, or FDA) for DICAPRYLOYL CYSTINE were identified. The ingredient does possess a UNII (BV1DW20UDP) in the Global Substance Registration System, indicating recognition.
