Products Description
Cetyltrimethylammonium chloride (CTAC) is a quaternary ammonium compound that is commonly used as a surfactant, emulsifier, and antimicrobial agent. Its chemical formula is C21H38ClN, and it is often found in various personal care products, such as shampoos, conditioners, and skin creams, due to its ability to reduce surface tension and improve the texture and stability of formulations.
Properties:
- Appearance: Typically a white or off-white solid or powder.
- Solubility: Soluble in water and organic solvents.
- Functionality: Acts as a cationic surfactant, which means it carries a positive charge and can interact with negatively charged surfaces, such as hair and skin.

Benefits
- Surfactant: CTAC has good surface activity, which can reduce the surface tension of liquids, help form foams and emulsions, and improve the texture and stability of products.
- Conditioning agent: In hair care products, CTAC can interact with the negative charge of the hair to form a protective film, increase the smoothness and softness of the hair, and reduce static electricity and frizz.
- Antibacterial effect: CTAC has a broad spectrum of antibacterial and antifungal activity and can inhibit the growth of a variety of bacteria and fungi, so it is often used in disinfectants and preservatives.
- Emulsifier: In cosmetics and skin care products, CTAC can help oil and water mix with each other to form a stable emulsion.
Applications
Personal care products:
- Shampoo and Conditioner: For improving the smoothness and combability of hair.
- Skin Care: Acts as an emulsifier and conditioning agent to enhance the feel of products.
- Body Wash: Increases lather and cleansing effect.
Disinfectant and antiseptic: Due to its antimicrobial properties, CTAC is often used in household and industrial cleaning products.
Industrial Application:
- Textile and paper industry: as an auxiliary agent to improve the handling properties of materials.
- Coatings and inks: used as dispersants and emulsifiers to improve product stability.
