Applications of Sodium Cocoyl Glycinate
Daily necessities/household products:
* Facial Cleansing Products (facial cleansers, cleansing powders, cleansing mousses, etc.): The addition of gentle Sodium Cocoyl Glycinate results in fine and rich foam, leaving the facial skin feeling neither dry nor tight after use.
* Shampoos and hair care products: Sodium N-cocoyl glycinate, as an ingredient in shampoo formulations, effectively cleanses the scalp and hair without causing irritation.
* Shower Gels and Soaps: Sodium Cocoyl Glycinate is suitable for sensitive skin, children, dry skin, and winter use. It helps maintain skin moisture and prevents dryness and itching.
* Oral Care Products: This is an emerging application of SCG, commonly used in some high-end or children’s toothpastes and mouthwashes, providing a pleasant taste and minimizing potential irritation to the oral mucosa.
Household Cleaning Products:
It has good biodegradability and is suitable for groups that require safety and environmental protection, helping to reduce detergent residue on items and tableware.
* Baby-specific detergents
* High-end household cleaning agents
* Fruit and vegetable cleaning agents
Other Professional Fields：
* Pet Grooming Products: It not only reduces irritation to pets’ eyes and skin but also softens their fur.
* Cosmetics: Used as an emulsifier and solubilizer, and as an auxiliary ingredient in formulations requiring gentleness.
