Science
Mechanism of Action
By incorporating an isostearoyl fatty acid, this protein significantly increases its affinity for keratinous surfaces. It forms a protective, moisture-retaining film that smooths the skin and hair, while also helping to mitigate surfactant-induced irritancy.

Formulation
Stability
Stable across typical cosmetic pH ranges (4-7), this ingredient is uniquely both alcohol-soluble and water-dispersible. Commercial hydrolysates are often supplied at pH 4.0–5.0 for optimal performance.
Conflicts
- Highly anionic systems may cause precipitation of protein complexes
- Strongly alkaline conditions (> pH 9) can degrade protein structure
Safety
Safety Profile
Safety is established when formulated with peptides restricted to a weight-average molecular weight of 3500 Da or less, to prevent Type 1 hypersensitivity. It is not recommended for use on damaged skin or in inhalable products unless safety for those uses is specifically established.
