Applications of Disodium Cocoyl Glutamate
High-end personal care products: Disodium cocoyl glutamate (cosmetic grade) is used in personal cleansing and skincare products, enhancing the safety, mildness, and luxurious feel of the products.
- Cleansing Products: DCG, a weakly acidic, non-viscous, transparent fluid, is used as an ingredient in facial cleansers for sensitive skin. It leaves the face feeling comfortable after washing, without dryness or tightness.
- Shampoos and Shower Gels: N-cocoyl-L-glutamate disodium is added to shampoos and shower gels. Its superior performance is evident in terms of foam richness, ease of rinsing, and moisturizing properties.
- Oral Care: L-cocoyl glutamate disodium is commonly used in gentle toothpastes to reduce irritation to the oral mucosa and provide moderate cleaning ability.
- Skincare Emulsifier: Cocoyl glutamate disodium is used as an O/W emulsifier in lotions, creams, and sunscreens. Besides stabilizing the product formula, it also optimizes the product texture, making it lighter and easier to absorb.
Dedicated to Mothers & Children
Due to its extremely low irritation to the eyes and skin, and excellent biodegradability, disodium cocoyl glutamate is the best choice for infant and toddler products and products specifically designed for pregnant women.
Environmentally friendly household cleaning products
- Washing delicate fabrics: Disodium cocoyl glutamate is an important ingredient in specialized detergents for high-end silk and wool fabrics, protecting clothing fibers from damage.
- Cleaning tableware and fruits and vegetables: Disodium cocoyl glutamate has natural, low-toxicity, and easy-rinsing properties, and is used in fruit and vegetable detergents and high-acid hand dishwashing liquids.
