Polyoxyethylene stearate, with the CAS number 9004 - 99 - 3, is a non - ionic surfactant. It is an important chemical product in the field of industrial and daily chemical applications. Our product, High Quality Polyoxyethylene stearate, features high purity and excellent quality at a very competitive price.
Physically, it usually appears as a white to pale yellow waxy solid. Its melting point generally ranges from 30 - 50°C, and it has good solubility in water and common organic solvents such as ethanol and acetone. The molecular formula of polyoxyethylene stearate is C₁₈H₃₆O₂(C₂H₄O)n, where the value of n represents the degree of polymerization of ethylene oxide units, which can vary according to different product specifications and application requirements. This variation in the degree of polymerization affects the physical and chemical properties of the product, such as its hydrophilic - lipophilic balance (HLB) value. The HLB value of our polyoxyethylene stearate can be adjusted to meet different application needs, typically ranging from 10 - 18.
1. Cosmetics Industry: In cosmetics, polyoxyethylene stearate is widely used as an emulsifier, solubilizer, and dispersant. It can effectively mix oil - based and water - based ingredients, creating stable and homogeneous emulsions. For example, in skin creams and lotions, it helps to disperse the oil phase evenly in the water phase, improving the texture and stability of the product. It also enhances the solubility of some oil - soluble active ingredients, making them more effectively absorbed by the skin.
2. Pharmaceutical Industry: In the pharmaceutical field, it is used as an excipient. It can be used in the preparation of oral drugs, injection drugs, and topical drugs. As an emulsifier in drug formulations, it can improve the bioavailability of poorly soluble drugs by increasing their dispersion in the body fluids. In topical ointments, it helps to form a stable emulsion, ensuring uniform distribution of the drug and better skin adhesion.
3. Textile Industry: As a softener and antistatic agent in the textile industry, polyoxyethylene stearate can improve the softness and smoothness of fabrics. It reduces the friction between fibers, making the fabric feel more comfortable to the touch. At the same time, it can eliminate static electricity on the fabric surface, preventing dust adsorption and reducing the risk of static - induced fire in some industrial environments.
When using polyoxyethylene stearate, first, determine the appropriate dosage according to the specific application requirements. In general, for cosmetic emulsions, the dosage is usually 1% - 5%. In pharmaceutical formulations, the dosage may vary depending on the type of drug and the formulation requirements, typically ranging from 0.5% - 3%.
To prepare an emulsion, heat the oil phase and the water phase separately to a suitable temperature, usually around 70 - 80°C. Then, slowly add the polyoxyethylene stearate to the oil phase and stir well until it is completely dissolved. Next, gradually add the oil phase containing the emulsifier to the water phase under high - speed stirring. Continue stirring for a certain period until a stable emulsion is formed. After the emulsion is cooled to room temperature, other additives such as preservatives and fragrances can be added.
1. Cosmetic Emulsion: A well - known cosmetic brand used our polyoxyethylene stearate in their new moisturizing cream. They added 3% of the product to the formula. After the production process, the cream showed excellent stability during storage. It had a smooth texture, and consumers reported that it was easy to apply and quickly absorbed by the skin. The sales of this product increased significantly due to its high - quality performance.
2. Pharmaceutical Ointment: A pharmaceutical company used our polyoxyethylene stearate in the preparation of a topical anti - inflammatory ointment. By adding 2% of the product, they achieved a stable emulsion. The ointment had good adhesion to the skin, ensuring that the drug was evenly distributed on the affected area. Clinical trials showed that the ointment had better efficacy compared to the previous formulation without the emulsifier.
3. Textile Softening: A textile factory used our polyoxyethylene stearate as a softener for cotton fabrics
