Polyglyceryl - 3 diisostearate, with the CAS number 66082 - 42 - 6, is a commonly used ingredient in various industries. This product is supplied directly from the factory, ensuring high - quality and cost - effective solutions.
It is a non - ionic surfactant. Its chemical structure combines polyglycerol and isostearic acid groups. Physical properties include a relatively high melting point, which makes it suitable for use in products that require stability at different temperatures. It is typically a pale - yellowish, viscous liquid at room temperature, with good solubility in most organic solvents and compatibility with a wide range of other ingredients.
In the cosmetic industry, Polyglyceryl - 3 diisostearate plays a significant role. It is widely used as an emulsifier in creams, lotions, and ointments. By reducing the surface tension between oil and water phases, it helps to create stable emulsions, which prevent the separation of oil and water over time. This property is crucial for the long - term stability and quality of cosmetic products.
It is also used in the food industry. As a food emulsifier, it can improve the texture and stability of food products. For example, it can be added to margarine or salad dressings to prevent oil droplets from coalescing, resulting in a more homogeneous and appealing product.
In the pharmaceutical industry, it can be used as an excipient in the formulation of certain drugs. It helps in the dispersion of active ingredients and can improve the bioavailability of some poorly - soluble drugs.
When using Polyglyceryl - 3 diisostearate in cosmetic formulations, it is usually added during the emulsification process. First, heat the oil and water phases separately to a suitable temperature, typically around 70 - 80°C. Then, slowly add the Polyglyceryl - 3 diisostearate to the oil phase while stirring continuously. After that, gradually add the water phase to the oil phase under high - speed stirring to form a stable emulsion. The recommended dosage in cosmetic products is usually between 1% - 5%, depending on the specific formulation and desired properties.
In the food industry, it should be added according to the food production process. It can be added directly to the oil or water phase during the mixing process. The dosage is strictly regulated by food safety standards and should be within the permitted range.
In pharmaceutical applications, the usage method and dosage are determined by the specific drug formulation and manufacturing process. It requires strict compliance with pharmaceutical production regulations.
Cosmetic Case: A well - known skincare brand was facing the problem of emulsion instability in their moisturizing cream. After adding 3% Polyglyceryl - 3 diisostearate to their formula, they observed a significant improvement in the stability of the cream. The product remained homogeneous even after being stored at different temperatures for an extended period. This led to an increase in customer satisfaction as the product maintained its quality over time.
Food Case: A food company producing salad dressings was experiencing oil separation issues. By incorporating 2% Polyglyceryl - 3 diisostearate into their recipe, the oil droplets were uniformly dispersed in the water phase. The salad dressing had a smooth texture and better visual appearance, resulting in increased sales due to improved consumer acceptance.
Pharmaceutical Case: A pharmaceutical company was developing a new oral drug with a poorly - soluble active ingredient. By using Polyglyceryl - 3 diisostearate as an excipient, they were able to improve the dissolution rate of the active ingredient. Clinical trials showed that the bioavailability of the drug was significantly enhanced, leading to better therapeutic effects.
