Preparation method for manually ground soap

Abstract

The invention discloses a preparation method for a manually ground soap, which comprises the following steps: after a soap base is prepared, feeding the soap base into a three-roller mill to carry out primary grinding so as to obtain a flaky soap base; detecting the pH of the flaky soap base obtained after primary grinding and if the pH value is greater than 9, adding weak acid into the flaky soap base obtained after primary grinding to regulate the pH value; after the weak acid is added, carrying out grinding again, confirming that the pH value is reduced into the use range, and feeding the soap base subjected to pH value regulation into a soap plodder for extrusion molding; after extrusion molding, printing by a soap cold printing machine to obtain the manually ground soap and packaging to obtain the finished product. According to the invention, the pH value of the soap is regulated in the grinding process, thus, after the soap preparation process is finished, the obtained manually ground soap can be immediately used; in the grinding process, all or most of soap crystal phases are transformed into beta crystal phases by grinding and pressing through mechanical force, thus, compared with an unground soap, the prepared soap has high solubility, strong foaming capacity and fine washing feeling.

Description

technical field [0001] The invention relates to a preparation method of soap, in particular to a preparation method of hand-grinding soap. Background technique [0002] The concept of "handmade soap" first appeared in mainland China in 2008, and it was introduced from Japan, Taiwan and other surrounding countries and regions with advanced skin care culture. Handmade soap was initiated by young people who pursue the concept of natural skin care without additives, and is used to replace facial cleanser, a new wave of niche consumption. [0003] The main component of facial cleanser is chemically synthesized surfactant, long-term use will cause cumulative skin damage, and synthetic surfactant is an important source of pollution of environmental water. According to the investigation, the important pollution sources of environmental water bodies are detergents in industrial wastewater and domestic sewage, referring to synthetic surfactants. The extensive use of synthetic surfac...

Problems solved by technology

And the disadvantage of the hand-grinding soap made by the current grinding process is that the hand-kneaded shape is not beautiful, and many granular soap pieces can be seen to stick together, and it is easy to fall apart when entering water; and the production difficulty of hand-grinding soap is greater than that of manual soap. Cold-processed soap is time-consuming and labor-intensive, resulting in much lower output than manual cold-processed soap
