The Song people were careful about the "Old Things of Wulin", volume 6, "Little Brokerage", which recorded that in the Southern Song Dynasty, there were already businessmen who specialized in operating "soap groups" in Lin'an, Kyoto.

Ming Li Shizhen's "Compendium of Materia Medica" recorded the manufacturing method of "soap group": soap locust grows in the high mountains, the tree is tall, the leaves are like sandalwood and honey locust leaves, blooms in May and June, bears pods three or four inches, fat and fleshy, there are several sunspots in it, as big as a finger, not round, there are white kernels, edible.

The locals worship the heavens with animals, and due to the use of wood when burning animals, the ash of wood and animal fat are mixed to produce a soap-like yellow substance. Heavy rains washed these things into the river, where local women often do laundry, and they found that their clothes were cleaner as a result.

Before 2500 B.C., potassium soap was made from oils and vegetable ash containing potassium carbonate, and wool was washed with this soap. Since the 19th century, due to the use of the alkali production method of Lubran, the production of soap has entered the stage of industrialization, and it reached its peak in the middle of the 20th century.

In the late 80s of the 20th century, Unilever and Shangsoapchang jointly produced high-quality "Lux" beauty and skin care soap, which promoted the development of the domestic soap industry. In the early 90s, Procter & Gamble produced antibacterial and healthy "Shufjia" soap in China, which further led to the development of the domestic soap industry. In the late 90s, the market share of domestic soap gradually expanded.

And liquid soap, liquid soap, also known as bath liquid, appeared.

The role of soap.

Soap is an indispensable detergent and care product in daily life, which is made of fatty acid sodium and other surfactants as the main raw materials, adding quality improvers and appearance improvers, and after processing and molding. Generally, soaps can be divided into seven categories:

Soap in general. Spices, pigments and soaps are ground and pressed into various shapes, which is the most economical and has a good effect on general cleaning and grease removal. (

Carefully grind the soap. Also known as French soap, it contains less alkaline and is made into a solid soap after many grinding, this kind of soap is of course more expensive, because it is more stable and finer, so it is more commonly used as a face wash.

Floating water soap. It is a kind of soap with slightly higher humidity and no grinding, which is easy to contain the characteristics of air when used, and is easier to float on the surface of the water, and the cleaning effect is not bad but it is difficult to maintain humidity, and it is easy to deform and change color after storage, so it should be used when it is fresh.

Oil-based soaps. Add a high concentration of oil when grinding, and a layer of oil will be formed on the surface of ** when washing, which is suitable for people with dry skin, but the washing effect is slightly worse. Because it is often used on babies, it is also called baby soap.

Clear soap. Contains more than 10% glycerin and some vegetable oils, after use** feel slippery, very similar to oil-based soap, commonly used for people who wash their faces or dry skin.

Special types of soaps.

Such as liquid, colloidal, or medical, as needed, add fungicides, scrubs, medicines, deodorants, etc., among which olive oil and sodium hydroxide are added called castile soap. The cleaning liquids and emulsions produced by cosmetics companies are not liquid soaps, but emulsions or creams containing emulsifiers, which are mainly designed to remove special cosmetics.

Essential oil soaps. A very popular soap in recent years, mainly made from plant essential oils.

In hard water, soap and Ca2+, Mg2+, etc., form curd-like substances, fatty acids, calcium salts, etc., which are commonly referred to as "calcium soaps" and become useless descalers. Adding a softener to hard water removes hard water ions and allows the soap to work.
