Science
Mechanism of Action
Hydrolyzed Hemp Seed Protein Hydroxypropyltrimonium Chloride operates by enhancing the skin's inherent hydration capacity, primarily by acting as a moisture-boosting agent that directly targets dry and flaky conditions. It contributes to maintaining optimal skin pH and promotes the natural synthesis of hyaluronic acid, critical for deep hydration. Furthermore, it fortifies the skin's lipid barrier, supports collagen production for improved elasticity, and helps restore epidermal homeostasis, thereby aiding in self-healing and optimizing the absorption of other active ingredients.

To maintain optimal integrity, exposure to temperatures exceeding 40°C (104°F) should be avoided. If heat is necessary during the formulation process, the ingredient should be incorporated during the cool-down phase once the temperature drops below 45°C.
Safety
Safety Profile
The core component, 'Hydrolyzed Hemp Seed Protein,' has been included in a broader 'Safety Assessment of Plant-Derived Proteins and Peptides as Used in Cosmetics.' Rat feeding studies with up to 1.0% hydrolyzed hemp seed meal protein reported no adverse effects. While the FDA has granted GRAS status for hulled hemp seed, hemp seed protein powder, and hemp seed oil for human food consumption, this status does not directly pertain to this specific cosmetic ingredient or its topical application. This ingredient is currently listed as 'Not rated' by Paula's Choice, indicating its novelty in the cosmetic market.
