High Quality Span 80 with CAS number 1338 - 43 - 8 is a non - ionic surfactant. It is also known as sorbitan monooleate. Physically, it appears as a yellowish to amber viscous liquid at room temperature.
Some key parameters of this product include: its molecular formula is C24H44O6, and the molecular weight is approximately 428.6 g/mol. It has a density of about 0.98 g/cm³. The HLB (Hydrophilic - Lipophilic Balance) value of Span 80 is around 4.3, which makes it more lipophilic, suitable for applications where an oil - in - water emulsion is required.
Span 80 has a wide range of applications in various industries. In the food industry, it is used as an emulsifier, stabilizer, and dispersant. It can prevent oil droplets from coalescing in food products such as margarine, salad dressings, and ice cream, thus improving the texture and stability of the final products.
In the cosmetic industry, this product is used in the formulation of creams, lotions, and makeup products. It helps to mix oil and water - based ingredients evenly, enhancing the skin - feel and appearance of the cosmetics. Moreover, in the pharmaceutical industry, Span 80 can be used as a solubilizer and emulsifier in drug formulations, which helps to improve the bioavailability of poorly - soluble drugs.
When using Span 80, it is recommended to first determine the appropriate dosage according to the specific application. For food products, the dosage usually ranges from 0.1% - 1% of the total weight of the product. In cosmetics, the dosage can be adjusted according to the desired emulsion stability and texture, typically around 0.5% - 2%.
To use it, first add Span 80 to the oil phase of the formulation. Stir it well to ensure it is completely dissolved in the oil. Then, slowly add the water phase to the oil phase while continuously stirring. The stirring speed and time should be adjusted according to the volume and nature of the formulation. For large - scale production, high - shear mixing equipment may be required to obtain a fine and stable emulsion.
Case 1: Ice Cream Production
A well - known ice cream manufacturer was facing the problem of ice crystal formation and poor texture in their products. After adding 0.5% Span 80 to their ice cream formulation, they noticed a significant improvement. The ice cream had a smoother texture, and the ice crystal formation was greatly reduced. The product also had better over - run, which means more air was incorporated during the freezing process, resulting in a lighter and creamier ice cream. Customers preferred this new - formulated ice cream, leading to an increase in sales.
Case 2: Cosmetic Lotion
A cosmetic company wanted to develop a new moisturizing lotion. They used Span 80 as an emulsifier in the formulation. By adding 1% Span 80 to the oil phase and then emulsifying it with the water phase, they obtained a stable and homogeneous lotion. The lotion had a good spreadability and a non - greasy feel on the skin. The product was well - received in the market due to its excellent performance.
