(5) molding treatment:

dividing the soap solution prepared in the step (4) into two parts, directly injecting one part into a mold, adding volcanic rock and rubble powder with the mass of 1/30 into the other part, uniformly stirring, injecting into the mold, and standing for 3-5 days;

(6) demolding and cutting treatment:

and (3) standing the die for 3-5 days, then demoulding, cutting the demoulded soap, then putting the soap into an incubator for heat preservation for 2-3 days, finally taking out and airing the soap in a dry and ventilated space, and obtaining the finished handmade soap after 45-90 days.

2. The method for preparing a long-lasting moisture-retaining handmade soap according to claim 1, wherein the time interval of each addition of the sodium hydroxide in the step (2) is 30 s.

3. The method for preparing a long-lasting moisture-retaining handmade soap according to claim 1, wherein the soap solution in the step (5) is divided into two parts, wherein the two parts correspond to each other in a weight ratio of 7: 3; the larger portion is injected directly into the mold.

4. The method for preparing a long-lasting moisture-retaining handmade soap according to claim 1, wherein the temperature in the heat-retaining box is controlled to be 24-26 ℃ during the heat-retaining treatment in the step (6).

Technical Field

The invention belongs to the technical field of soap preparation, and particularly relates to a preparation method of a long-acting moisturizing handmade soap.

Background

The hand-made cold soap is a cleaning and skin-care soap which is developed in recent years, can be manufactured by DIY and can be produced manually in batches, and the basic preparation principle is that vegetable oil and fat are subjected to saponification reaction with alkali at a low temperature (lower than 40 ℃) to generate high-content (more than 20%) natural glycerin and fatty acid salt surfactant, and other auxiliary raw materials are added to prepare the hand-made cold soap. The handmade soap has delicate and rich foam, can remove oil stains in the deep part of pores, moisten and smooth skin, lock water and have elasticity, and is popular with consumers. At present, handmade soaps are on the market more and more, and the efficacy is not only limited to cleaning but also endowed with more skin care efficacy. Particularly, the vegetable oil with unique skin care effect is reserved through a super-fat process, so that the handmade soap has the specific skin care effect of certain vegetable oil.

The existing manual cold soap preparation method has the problems of improper control of process conditions, poor appearance of the prepared manual soap, low yield and the like, and the service performance of the manual soap is general, so that continuous optimization and improvement are needed.
