Stearamidopropyl Dimethylamine SD

Description

Stearamidopropyl Dimethylamine (SDA)

Stearamidopropyl dimethylamine is an emulsifier, conditioning agent and surfactant with cleansing properties which is commonly used in hair care products to condition and improve the appearance of hair. It can be used in formulas as a replacement to silicones since they are not easily broken down, and is biodegradable. Functions as a skin conditioner.

Suitable for making no-build up products. Improves the substantivity of proteins and quaternary conditioners, It is used in shampoos or hair conditioners due to its antistatic effect. It serves as a mild surfactant that removes dirt build-up from the hair. It imparts a soft and silky feel to the hair, making it easier to comb through. It possesses a positive charge which can help offset the negative charge from shampooing the hair.

Stearamidopropyl Dimethylamine is a cationic surfactant derived from vegetable-based stearic acid. It serves as a hair conditioning agent, emulsifier, and mild cleanser, making it a popular ingredient in hair care formulations—especially conditioners, leave-in treatments, and 2-in-1 shampoos. Known for its anti-static, detangling, and softening properties, SDA is a great alternative to traditional quaternary ammonium compounds due to its biodegradability and lower toxicity.

Its functions:
Antistatic : Reduces static electricity by neutralizing electrical charge on a surface.

Emulsifying : Promotes the formation of intimate mixtures between immiscible liquids by modifying the interfacial tension (water and oil).

Hair conditioning : Leaves hair easy to comb, soft, soft and shiny and / or confers volume, lightness and shine.

Surfactant : Reduces the surface tension of cosmetics and contributes to the even distribution of the product when it is used.

BENEFITS OF USING SDA:

• Excellent hair detangling and softening

• Anti-static effect that reduces frizz and flyaways

• Improves combability of wet and dry hair

• Vegetable-derived and biodegradable

• Compatible with silicones, proteins, and natural oils

• Acts as a co-emulsifier in cream and lotion formulations

• Milder and more eco-friendly than conventional cationic surfactants
