Usage

Description

Sucrose stearate is a sucrose fatty acid ester, which is a type of nonionic surfactant derived from sucrose and stearic acid. It is characterized by its low foaming properties, high hydrophilic-lipophilic balance (HLB) value of 14.5, and a melting point between 44-52°C. Sucrose stearate is a white powder that is widely used in various industries due to its emulsifying, detergency, and emollient properties.

Uses

1. Used in Detergency and Surfactants:
Sucrose stearate is used as a low-foam nonionic detergent and surfactant for various cleaning and personal care products. Its low foaming characteristic makes it suitable for applications where excessive foam is undesirable.
2. Used in Cosmetics and Personal Care:
Sucrose stearate is used as an emollient and emulsifying agent in makeup preparations. It helps in formulating clear gel microemulsion systems with a reduced physiological effect on the skin and eyes, providing a gentle and soothing experience for users.
3. Used in Pharmaceutical Industry:
Sucrose stearate is used to enhance the oral delivery of drugs like alendronate by improving intestinal absorption. This property makes it a valuable component in the development of drug formulations that aim to increase the bioavailability of certain medications.
4. Used in Food Industry:
Sucrose stearate displays antibacterial properties towards various bacteria, including Bacillus cereus, Bacillus subtilis, Staphylococcus aureus, Escherichia coli, and Salmonella typhimurium. This makes it a potential candidate for use in the food industry as a preservative or additive to improve the safety and shelf life of certain products.
