1. Sucrose Stearate

Sucrose stearate is a non-ionic emulsifier synthesized from sucrose and stearic acid. It is typically a white to off-white powder or waxy solid, with good emulsifying, dispersing and stabilizing properties. It is soluble in hot water and most organic solvents, and shows excellent compatibility with other emulsifiers, surfactants, and food ingredients.

Featured by high safety, sucrose stearate is non-toxic, mild to the human body, and has no irritation to skin and mucous membranes. It is approved as a food additive in most countries and regions, and also widely used in cosmetics and pharmaceuticals due to its eco-friendly and biodegradable characteristics.

Main Applications

Food Industry: It is a common emulsifier and stabilizer used in baked goods, dairy products, confectionery, and beverages. In bread and cake production, it improves dough elasticity and gas retention, making the final products softer and with a better texture. In ice cream, it inhibits ice crystal growth, enhancing smoothness and melting resistance. In dairy drinks, it prevents oil-water separation and maintains system stability during storage.

Cosmetics and Personal Care Industry: It serves as an emulsifier and conditioner in skincare products such as creams, lotions, and facial cleansers. It helps form stable oil-water emulsions, improves product spreadability, and leaves the skin soft and non-greasy. It is also added to hair care products to reduce static electricity and improve hair combability.

Pharmaceutical Industry: It acts as a solubilizer and emulsifier for oral and topical preparations, helping to dissolve fat-soluble drugs and improve their bioavailability. It can also be used as a coating agent for tablets to enhance their stability and dissolution rate.

2. Sodium Stearoyl Lactylate

Sodium stearoyl lactylate, abbreviated as SSL, is an anionic emulsifier derived from stearic acid and lactic acid, then neutralized with sodium hydroxide. It is usually a white to creamy yellow powder or granular solid, with strong emulsifying, foaming and gluten-strengthening properties. It is dispersible in hot water and soluble in oils and fats, and has good heat resistance and stability under acidic conditions.

SSL is recognized as a safe food additive with low toxicity, and its application complies with the standards of FAO/WHO and other international food safety organizations. It also has certain applications in the daily chemical and textile industries.

Main Applications

Food Industry: This is the core application field of SSL. It is widely used in flour products such as bread, steamed buns, and noodles. It can interact with wheat gluten proteins to form a stable network structure, improving the elasticity and toughness of the dough, increasing the volume of baked or steamed products, and making the internal structure uniform and delicate. It also extends the shelf life of flour products by delaying staling. In addition, it is used in dairy products, margarine, and processed meats as an emulsifier and stabilizer to prevent stratification and improve product quality.

Daily Chemical Industry: It is used as an emulsifier and thickener in cosmetics such as creams and lotions, helping to stabilize the emulsion system and improve product texture. In hand sanitizers and shower gels, it can enhance foam stability and cleaning effect while maintaining mildness to the skin.

Textile Industry: It serves as a softener and antistatic agent in fabric finishing. It can form a protective film on the surface of fibers, improving the softness and smoothness of fabrics and reducing static electricity generated during processing and wearing.
