Cosmetic Peg-150 Stearic Acid Ester CAS 9005-08-7
Products Description
- PEG-150 Stearic Acid Ester is a synthetic polymer used primarily in cosmetics and personal care products as an emulsifier, thickener, and skin conditioner. It is made by reacting polyethylene glycol (PEG) with stearic acid (Stearic Acid).
- PEG-150 Stearic Acid Ester has relatively good hydrophilicity, mainly due to the polyethylene glycol part. It can form a transparent or semi-transparent dispersion system in water and also has good solubility in some polar organic solvents (such as alcohols). However, due to the presence of the stearic acid part, its solubility in non-polar organic solvents is relatively weak.
- PEG-150 Stearic Acid Ester is a versatile emulsifier and thickener with good lubricity and substantivity. Its wide application in personal care and cosmetics makes it one of the most important ingredients in modern skin care and cleansing formulations. Due to its good skin feel and stability, PEG-150 Stearic Acid Ester is often used in high-end skin care and beauty products.
Function
- Emulsifier: As an emulsifier, PEG-150 Stearic Acid Ester can help oil and water phases mix to form a stable emulsion. It is commonly used in skin creams, lotions and cosmetics.
- Thickener: PEG-150 Stearic Acid Ester can increase the viscosity of the product, improving the texture and feel of the product.
- Skin Conditioning Agent: PEG-150 Stearic Acid Ester has good skin affinity, can improve the product’s spreadability and usage experience, and provide a smooth and moisturizing feel.
- Stabilizer: In certain formulations, PEG-150 Stearic Acid Ester can act as a stabilizer to help maintain product uniformity and stability.
Application
- Cosmetics Field
Emulsifier: Peg-150 Stearic Acid Ester is used as an emulsifier in skin care products such as emulsions and creams. It can effectively mix the oil phase and the water phase together, form a stable emulsion structure, prevent the emulsion from separating, and ensure the stability and effectiveness of the products.
Thickener and Lubricant: Peg-150 Stearic Acid Ester can increase the viscosity of products, improve the texture of products and make cosmetics have better rheological properties. Meanwhile, it can also reduce the friction between the skin and cosmetics to some extent, making the products smoother to use.
- Pharmaceutical Field
In some pharmaceutical preparations, Peg-150 Stearic Acid Ester can be used as a drug carrier or an auxiliary ingredient. For example, it can help drugs disperse better in the medium or adjust the physical properties of pharmaceutical preparations, such as viscosity and stability, to improve the operability and effectiveness of drugs.
- Industrial Field
In industrial products such as coatings and inks, Peg-150 Stearic Acid Ester can be used as a dispersant or a rheology modifier. It helps the dispersion of pigments or other solid particles in liquid media and can adjust the rheological properties of products, enabling products to have better fluidity and coating performance during the application process.
