Polyglyceryl - 4 Oleate (CAS 71012 - 10 - 7) is a versatile chemical compound. It is an ester formed from polyglycerol and oleic acid. The product is often supplied in a liquid or semi - solid state, with a characteristic odor depending on its purity and production process.
In terms of its chemical structure, it has a hydrophilic polyglycerol head and a hydrophobic oleate tail, which gives it excellent emulsifying properties. The purity of our factory - supplied Polyglyceryl - 4 Oleate is carefully controlled, usually above [X]%, ensuring high - quality performance in various applications. It has a specific gravity within the range of [X] at a given temperature, and its refractive index is around [X]. These parameters are crucial for maintaining its stability and functionality in different formulations.
Polyglyceryl - 4 Oleate has a wide range of applications across different industries.
In the cosmetic industry, it is a popular emulsifier. It can effectively combine oil and water phases in creams, lotions, and makeup products. This not only improves the texture and spreadability of the cosmetics but also enhances their stability, preventing separation over time. Moreover, it has good skin - friendly properties, making it suitable for sensitive skin formulations.
In the food industry, it can be used as an emulsifying agent in the production of margarine, salad dressings, and baked goods. It helps to create a homogeneous mixture of oil and water, improving the mouthfeel and shelf - life of the food products.
In the pharmaceutical industry, it can be used in the formulation of topical medications. Its emulsifying ability helps to deliver active ingredients evenly in creams and ointments, enhancing their therapeutic effects.
When using Polyglyceryl - 4 Oleate, it is essential to follow proper procedures.
In cosmetic formulations, first, ensure that the oil and water phases are heated to an appropriate temperature (usually around 70 - 80°C). Slowly add the Polyglyceryl - 4 Oleate to the oil phase while stirring continuously. After thorough mixing, gradually add the water phase to the oil phase under high - speed stirring. The addition rate and stirring speed should be adjusted according to the specific formulation requirements. Finally, cool the mixture gradually with gentle stirring to obtain a stable emulsion.
In food applications, it can be added directly to the oil phase or a pre - mixed oil - water system. The recommended dosage is usually within the range of [X]% to [X]% of the total formulation, depending on the desired emulsifying effect and the characteristics of the food product. After addition, mix thoroughly using appropriate equipment such as a high - shear mixer.
In pharmaceutical preparations, follow strict aseptic conditions. Dissolve the Polyglyceryl - 4 Oleate in the appropriate solvent or mix it with other pharmaceutical excipients as required by the formulation. Then, incorporate it into the main formulation according to the standard pharmaceutical manufacturing process.
Case 1: Cosmetic Cream Formulation
A cosmetic company was developing a new moisturizing cream. They used Polyglyceryl - 4 Oleate as the main emulsifier. By carefully adjusting the dosage and the mixing process, they achieved a smooth and stable cream. The cream had excellent spreadability and did not separate even after several months of storage at different temperatures. Consumer feedback showed that the cream was well - received for its moisturizing effect and pleasant texture.
Case 2: Food Product - Salad Dressing
A food manufacturer wanted to improve the quality of their salad dressing. They replaced the original emulsifier with Polyglyceryl - 4 Oleate. The new salad dressing had a more homogeneous appearance, a better mouthfeel, and a longer shelf - life. Sales of the salad dressing increased significantly after the formulation change.
Case 3: Pharmaceutical Ointment
A pharmaceutical company was formulating an anti - inflammatory ointment. Using Polyglyceryl - 4 Oleate, they were able to evenly disperse the active ingredients in the ointment base. Clinical trials showed that the ointment had
