Polyglyceryl-10 Oleate, with the CAS numbers 9007-48-1 and 79665-93-3, is a widely - used chemical compound in various industries. It is a non - ionic surfactant derived from glycerin and oleic acid. The polyglyceryl structure provides unique properties such as good emulsifying, dispersing, and solubilizing abilities.
Physically, it is usually in the form of a pale yellow to amber liquid or semisolid. It has a relatively low odor, which makes it suitable for applications where odor is a concern. Its HLB (Hydrophilic - Lipophilic Balance) value typically ranges from 12 - 16, indicating its ability to form stable oil - in - water emulsions.
In the cosmetic industry, Polyglyceryl - 10 Oleate is a popular ingredient in skin care products. It can be found in lotions, creams, and moisturizers. It helps to reduce the surface tension between oil and water phases, creating a smooth and stable emulsion. This results in products that are easy to apply and have a pleasant texture on the skin. It also has some emollient properties, which can help to keep the skin hydrated and soft.
In the food industry, it can be used as an emulsifier and stabilizer. For example, it can be used in salad dressings to prevent the separation of oil and vinegar, ensuring a homogeneous product. It can also be used in margarine and other fat - based products to improve their stability and texture.
Furthermore, in the pharmaceutical industry, it can be used in the formulation of topical creams and ointments. It helps to enhance the delivery of active ingredients through the skin, improving their efficacy.
When using Polyglyceryl - 10 Oleate in cosmetic formulations, it is typically added during the emulsification process. First, heat the oil and water phases separately to a suitable temperature (usually around 70 - 80°C). Then, slowly add the Polyglyceryl - 10 Oleate to the oil phase while stirring. 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%.
In the food industry, it can be added directly to the liquid or semi - liquid food products during the mixing process. The dosage should comply with the relevant food safety regulations. Generally, it can be used at a level of 0.1 - 1% depending on the specific application.
A cosmetic company was developing a new moisturizing lotion. They initially had trouble creating a stable emulsion with the existing emulsifiers. After incorporating Polyglyceryl - 10 Oleate at a concentration of 3%, they found that the lotion became more stable, with no signs of phase separation even after several months of storage at different temperatures. The lotion also had a better spreadability and a more luxurious feel on the skin, which led to positive customer feedback.
A food manufacturer was producing a low - fat salad dressing. The dressing tended to separate quickly, which was a major issue for consumer acceptance. By adding 0.5% Polyglyceryl - 10 Oleate, the dressing remained homogeneous for a much longer time. This not only improved the product's shelf - life but also increased customer satisfaction as they no longer had to shake the bottle vigorously before use.
