Problems solved by technology

But the disadvantage is that it is greatly affected by temperature. When the temperature is high, the viscosity decreases significantly and the material becomes thinner. When the temperature is low, the viscosity increases significantly. The material is not easy to pour out, which seriously affects the actual production and product use

Embodiment

[0034] According to table 2, utilize sodium lauroyl hydroxypropyl sulfonate (SLMI), sodium cocoyl methyl isethionate (SCMI), glyceryl laurate (GML) and water to prepare thickening system, the system's The preparation process is:

[0035] 1. Add SLMI or SCMI to water at 65°C, stir at 200rpm to dissolve completely;

[0036] 2. Add GML and stir slowly until it dissolves completely;

[0037] 3. Allow to cool.

[0043] The thickening system of each embodiment is detected, as follows:

[0044] Temperature performance test: For many thickeners, the rheological properties are greatly affected by temperature. Especially at low temperature, the fluidity of the system becomes poor, or even freezes. Taking Example 4 and the comparative example as examples, the influence of temperature on viscosity was investigated. ...

Abstract

The invention discloses a self-thickening system of fatty acyl alkyl sulfonate, a preparation method and application thereof. The system includes fatty acyl alkyl sulfonates and fatty acid glycerides; the mass percentages of the fatty acyl alkyl sulfonates and fatty acid glycerides are (5.0-20.0): (0.1-5.0). The thickening effect of the system is obvious, which can significantly improve the foam performance, no jelly at low temperature, and little viscosity change. In addition, the pH value has little effect on the system. The cleaning effect of the composition is more stable and long-lasting.

Description

technical field [0001] The invention belongs to the technical field of personal care, and relates to a self-thickening system of fatty acyl alkyl sulfonate, a preparation method and application thereof. Background technique [0002] Fatty acyl alkyl sulfonate is an anionic surfactant with natural fatty acid as raw material. It is mild in nature, resistant to hard water, has fine foam and is easy to rinse, and is naturally sourced and environmentally friendly and easy to degrade. It can be used in a variety of personal care cleaners. [0003] Sodium lauroyl hydroxypropyl sulfonate is a highly water-soluble fatty acyl alkyl sulfonate. It has excellent solubility in water, good transparency and stability, and is often used in advanced personal care products, especially baby care products. Sodium lauroyl hydroxypropyl sulfonate is mainly thickened with salt such as sodium chloride, and the addition of CAB betaine can also improve the thickening efficiency. But the disadvantag...
