Description

Composition, antibacterial hibiscus handmade soap and preparation method thereof

Technical Field

The invention relates to the technical field of daily chemical articles, and in particular relates to a composition, an antibacterial hibiscus handmade soap and a preparation method thereof.

Background

The toilet soap, also known as 'pancreas', is a chemical product for washing and decontamination, and the main component of the toilet soap is alkali metal salt or organic alkali salt of higher fatty acid. One end of the alkali metal salt or organic base salt of the higher fatty acid is a polar acid radical with a charge, and the other end is a nonpolar higher fatty acid carbon chain. When the acid radicals enter water, one end of the acid radicals with polarity can destroy the attraction among water molecules so as to reduce the surface tension of the water, and the water molecules are uniformly surrounded on the surface of the skin. One end of a nonpolar high-grade fatty acid carbon chain is deeply penetrated into oil stains, one end of an acid radical is dissolved in water, the combination mode can form small oil drops under the mechanical action, hydrophilic parts and one end of the acid radical are fully distributed on the surfaces of the oil drops, the oil drops are not gathered together again to form large oil stains, and the process is an emulsification process. After repeated for many times, all the oil stains form tiny oil drops and are dispersed in water, and then the oil stains can be easily washed away.

In recent years, with the increasing awareness of environmental protection, more and more consumers have begun to try to replace the conventional industrially produced toilet soaps with handmade soaps as daily washing products. The handmade soap is made up by using natural oil and alkali liquor as raw material through a certain preparation process.

In order to enrich the product types, people develop antibacterial handmade soaps. However, the existing bacteriostatic soap has poor hard water resistance and poor detergency under hard water conditions.
