Our Factory Supply Sorbitan Monostearate has the CAS number 1338 - 41 - 6. It is a non - ionic surfactant derived from sorbitol and stearic acid. Chemically, it has a unique molecular structure that gives it excellent emulsifying and dispersing properties. The product usually appears as a white to light yellow waxy solid at room temperature.
In terms of physical parameters, it has a melting point ranging from 47 - 52 °C. Its HLB (Hydrophilic - Lipophilic Balance) value is around 4.7, which indicates its moderate hydrophilic and lipophilic characteristics, making it suitable for many different formulations. It is insoluble in water but soluble in organic solvents such as ethanol, acetone, and ether.
Factory Supply Sorbitan Monostearate has a wide range of applications across various industries:
Food Industry: It is commonly used as an emulsifier, stabilizer, and dispersant in food products. For example, in ice - cream, it helps to prevent the formation of ice crystals, improves the texture, and extends the shelf - life. It can also be found in margarine, chocolate, and baked goods to enhance the overall quality.
Cosmetics Industry: Sorbitan monostearate is a key ingredient in many cosmetic formulations. It is used in creams, lotions, and makeup products as an emulsifier to blend oil and water phases effectively. This results in a smooth and stable product with good spreadability and a pleasant feel on the skin.
Pharmaceutical Industry: In pharmaceuticals, it serves as an emulsifying agent in ointments, creams, and suspensions. It helps to ensure the uniform distribution of active ingredients and improves the stability of the pharmaceutical products.
Food Applications: When using Sorbitan Monostearate in food products, it is recommended to first dissolve it in a suitable solvent or oil phase at an appropriate temperature. For ice - cream production, it can be added during the mixing process of the ice - cream base. The typical dosage ranges from 0.1% - 1% depending on the specific product requirements.
Cosmetic Applications: In cosmetics, it is usually added to the oil phase during the formulation process. Heat the oil phase to a temperature around 70 - 80 °C to melt the Sorbitan Monostearate completely. Then, gradually add the aqueous phase while stirring vigorously to form a stable emulsion. The amount used can vary from 0.5% - 5% based on the type of cosmetic product.
Pharmaceutical Applications: For pharmaceutical products, it should be incorporated into the formulation under aseptic conditions. It can be added to the oil or wax phase of ointments and then mixed with the aqueous phase to form a homogeneous product. The dosage is determined by the specific pharmaceutical formulation and regulatory requirements.
Ice - Cream Production: A large - scale ice - cream manufacturer was facing issues with ice crystal formation in their products, which affected the texture and consumer acceptance. After incorporating our Factory Supply Sorbitan Monostearate at a dosage of 0.5% into the ice - cream base, the ice crystal size was significantly reduced. The ice - cream became smoother and creamier, and the shelf - life was extended. This led to an increase in customer satisfaction and a boost in sales.
Moisturizing Cream: A cosmetic company was developing a new moisturizing cream. By using Sorbitan Monostearate as the main emulsifier at a concentration of 3%, they were able to create a stable and smooth emulsion. The cream had excellent spreadability and a non - greasy feel on the skin. Consumer tests showed high satisfaction with the product's performance, leading to successful market penetration.
Topical Ointment: A pharmaceutical firm was formulating a topical ointment for skin conditions. Incorporating Sorbitan Monostearate into the formulation helped to ensure the uniform distribution of the active ingredient. The ointment was easy to apply and had good adherence to the skin, improving the efficacy of the treatment.
