Cocoyl Hydrolyzed Keratin

What is Cocoyl Hydrolyzed Keratin?

Cocoyl Hydrolyzed Keratin is a specially processed ingredient obtained by hydrolyzing keratin—a tough, fibrous protein naturally found in animal hair, wool, and feathers—into smaller peptides, then attaching coconut-derived fatty acids (the 'cocoyl' part) to enhance solubility and functionality. This modification creates an amphiphilic molecule that works well in water-based formulas. Primarily featured in shampoos, conditioners, and body washes, it acts by depositing a protective film on hair shafts and skin surfaces. The fatty acid chains provide mild cleansing and emulsifying properties, while the protein fragments adhere to damaged areas, smoothing cuticles and improving texture without heavy residue. Its dual nature supports both rinse-off and leave-on applications in hair care, where it integrates into cleansing systems to balance washing and nourishing effects.

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.
Antistatic agent
Reduces static electricity and flyaways by improving surface conductivity, enhancing hair manageability and smoothness in conditioners and styling products.

Benefits

Enhances hair softness and ease of combing by smoothing the surface.

Provides antistatic benefits to reduce flyaways and improve manageability.

Offers mild cleansing that maintains natural moisture balance.
