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 1, use sodium lauroyl hydroxypropyl sulfonate (SLMI) \ cocoyl methyl isethionate sodium (SCMI), glyceryl laurate (GML) and water to prepare thickening system, the system The preparation process is:

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

[0036] 2. Add GML, stir slowly while adding until completely dissolved;

[0037] 3. Cool and serve.

Abstract

The invention discloses a self-thickening system of fatty acyl alkyl sulfonate as well as a preparation method and application of the self-thickening system. The system comprises fatty acyl alkyl sulfonate and fatty glyceride, the mass percentage ratio of fatty acyl alkyl sulfonate to fatty glyceride is (5.0-20.0): (0.1-5.0), after mixing preparation, the thickening effect of the system is obvious, the foam performance can be significantly improved, jelly is not generated at a low temperature, and the viscosity change is small; in addition, the influence of the pH value on the system is very small, and the system can be well applied to washing-off products. And the cleaning effect of the cleaning care composition is more stable and 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, its preparation method and application. Background technique [0002] Fatty acyl alkyl sulfonate is an anionic surfactant based on natural fatty acid. It is mild in nature, resistant to hard water, fine in foam and easy to rinse, natural and environmentally friendly in source, easy to degrade, and 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, adding CAB betaine can also improve the thickening efficiency. But the disadvantage is that it is greatly affected by temperat...
