Science
Mechanism of Action
Derived from yellow peas, Potassium Lauroyl Hydrolyzed Pea Protein undergoes a hydrolysis process, breaking it into smaller, more bioavailable peptides for enhanced absorption into the skin and hair. It functions as a multifaceted skin conditioning agent, supplying vital nutrients, improving skin texture, and fostering hydration and smoothness. By forming a delicate protective film, it effectively prevents transepidermal moisture loss and aids the skin's natural regeneration processes. Additionally, it acts as an emollient, softening the skin, and a surfactant, gently aiding in cleansing by capturing and rinsing away impurities.

Key findings
- 01 A multicenter, double-blind, randomized, placebo-controlled study involving adult patients with atopic dermatitis (AD) demonstrated that a topical formulation containing pea proteins (PP) alongside xyloglucan (XG) provided rapid and sustained relief, while also restoring skin barrier function. Within 8 days, six patients treated with the XG+PP formulation experienced complete resolution of their AD, with 15 others showing mild AD. By Day 28, 16 patients had no eczema, and five maintained mild AD, suggesting its potential as a safe alternative in AD management.

The Formula
Formulation
Stability
This ingredient generally exhibits high water solubility across a broad pH range, including acidic and neutral conditions. While generic pea protein solubility can be minimal between pH 4 and 6, the 'hydrolyzed' and 'potassium lauroyl' modifications likely enhance solubility within this broader range. However, exposure to extreme alkaline pH levels (above 10) or prolonged heating can denature the protein, potentially reducing its functional efficacy and solubility.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined that plant-derived proteins and peptides, including Hydrolyzed Pea Protein, are safe for use in cosmetic products at current concentrations, typically ranging from 0.5% to 1.5%. It has been safely tested at concentrations up to 25% in genotoxicity studies. This ingredient is considered hypoallergenic and rarely causes allergic reactions or irritation, rendering it highly suitable for sensitive skin types. It is also notably free from common allergens such as gluten and soy.
