Applications
- Cosmetics Field
In cosmetics, Polyhydroxystearic Acid is an excellent emulsifier. Due to the fact that its molecular structure contains both hydrophilic hydroxyl groups and lipophilic long-chain fatty acid parts, it can effectively reduce the surface tension at the oil-water interface, enabling the oil phase and the water phase to mix well and form a stable emulsion. For example, in emulsion-based skin care products, it can prevent the emulsion from separating and ensure the stability of the product during storage and use. In addition, it can also be used as a thickening agent to increase the viscosity of cosmetics and improve the texture and feel of the product during use.
- Paint and Ink Field
In paint and ink, Polyhydroxystearic Acid can be used as a dispersant. It can adsorb on the surface of pigment particles, causing mutual repulsion among the pigment particles, thus effectively preventing the aggregation of pigment particles and enabling the pigments to be evenly dispersed in the paint or ink. This helps to improve the color brightness and hiding power of paint and ink. Meanwhile, it can also improve the rheological properties of paint and ink, giving them better fluidity and coating performance.
- Plastic Processing Field
Polyhydroxystearic Acid can be used as a lubricant in plastic processing. During the plastic processing process, it can reduce the friction between plastics and processing equipment, making plastics easier to mold and process. Moreover, it can also improve the glossiness of the plastic surface and enhance the appearance quality of plastic products.
