Gluten-Related

What is Amp Isostearoyl Hydrolyzed Wheat Protein?

AMP-Isostearoyl Hydrolyzed Wheat Protein originates from wheat proteins enzymatically broken into peptides, then modified by attaching isostearoyl chains from branched fatty acids and neutralized with aminomethyl propanol. This creates an amphiphilic, conditioning agent with positive charge affinity for negatively charged hair and skin surfaces. Commonly featured in shampoos, conditioners, body washes, and lotions, it works by adsorbing onto keratin, creating a protective, lubricious film that minimizes friction between strands or skin cells. As a surfactant, it reduces surface tension for better foaming and rinse-off; as an emulsifier, it stabilizes oil-in-water mixtures for uniform textures. Its lipophilic modification enhances substantivity, allowing benefits to linger post-rinse without residue buildup.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Hair conditioning

Improves softness, shine, and manageability by reducing friction and static; commonly achieved with cationic agents, silicones, oils, or conditioning polymers.

Skin conditioning agent

Maintains skin softness, smoothness, and flexibility.

Surfactant

Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.

Cleansing agent

Removes dirt, oil, and impurities by lowering surface tension and forming micelles, enabling soils to be lifted and rinsed away from skin, hair, or teeth.

Emulsifying agent

Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.

Benefits

Enhances hair softness, shine, and ease of styling by coating strands.

Supports skin smoothness and flexibility in cleansing products.

Facilitates mild dirt removal and stable emulsions for better product performance.
