Description

Stearamidopropyl dimethylamine Anti-Static

Stearamidopropyl dimethylamine (SAPDMA) enhances both wet and dry combing in hair care formulations. Known for its low irritation profile and excellent anti-static properties, it pairs seamlessly with other quaternary ammonium surfactants.

Uniquely exhibiting both cationic and non-ionic characteristics, SAPDMA is highly compatible with anionic surfactants. This makes it an ideal choice for eco-friendly hair care, delivering gentle, skin- and eye-safe performance alongside thickening and conditioning benefits in shampoos.

SAPDMA is highly biodegradable with low toxicity. It is a versatile ingredient that functions as an emulsifier, wetting agent, dispersant, antistatic agent, and softener. Beyond hair care, it is utilized in detergents, rust inhibitors, thickeners, and biocides. When used in hair dyes, it improves color intensity and uniformity, minimizes processing damage, and provides lasting conditioning benefits.

Properties:

Thermal & pH Stability: Ensures formulation uniformity and prevents separation under varying environmental conditions.

Frizz & Dryness Control: Deeply softens the hair, eliminates frizz, and dramatically improves combability.

Eco-Friendly & Sustainable: Highly biodegradable, meeting the strict standards of modern green chemistry.

Performance Elevating: Enhances the sensory profile and premium feel of rinse-off and leave-on hair care products.

Common Applications of Stearamidopropyl dimethylamine:

Hair Care

Conditioners & Masks: Emulsifies oils for uniform application, boosts viscosity, and improves slip. It adsorbs onto the cuticle to lock in moisture, reduce friction, and enhance deep nutrient penetration.

Shampoos: Acts as an efficient thickener to adjust viscosity and improve user comfort.

Hair Dyes: Enhances pigment adhesion and depth of penetration for rich, even color payoff while minimizing processing damage.

Skincare & Emulsions

Texture & Delivery: Improves skin feel and acts as a penetration enhancer when paired with other active ingredients.

Emulsion Stabilizer: Optimizes interfacial tension between oil and water phases to prevent separation and extend shelf life.

Textile Industry

Fabric Softener: Cationic groups bond to fibers to reduce friction and prevent fabric pilling. Unlike traditional quats, it preserves natural hydrophilicity so fabrics stay breathable and soft without stiffening.
