Hydrolyzed Vegetable Protein is a mixture of amino acids and peptides derived from enzymatic or acid hydrolysis of plant proteins, used in skincare and haircare to provide temporary conditioning, moisture retention, and a smoothing film on skin and hair. It functions primarily as a humectant and surface conditioner rather than a deep-acting treatment.
| Reported effect | How often | Notes |
|---|---|---|
Contact irritation | Uncommon | Mild redness or stinging possible, often related to formulation pH or residual processing agents. |
Allergic contact dermatitis | Rare | Sensitization to specific protein fragments reported in isolated cases. |
Cross-reactivity in those with plant/food protein allergies | Rare | Theoretical risk if derived from wheat, soy, or other allergenic sources; relevant for sensitive individuals. |
Anaphylaxis | Very rare | Documented mainly with hydrolyzed wheat protein in cosmetics, particularly via mucosal or broken-skin exposure. |
