[Wholesale fatty acid supply] Do you know these acids in soap-based shampoo formulas?

There are many types of shampoos. A good shampoo can not only clean your hair It does not harm the scalp and does not burden the hair. The bad ones are on the contrary. One of the soap-based shampoos has a bad reputation.

Soap base is a common surfactant, that is, a detergent. It has ideal cleaning ability, but it can also cause certain damage to the skin. Shampoos that use soap-based surfactants have strong cleaning capabilities and can be said to be the nemesis of oily heads. But it is a double-edged sword. While removing oil, it also removes the oil that protects the scalp, making the scalp dry and itchy. This kind of surfactant is the most irritating, so it is recommended for oily heads to use occasionally. Long-term use will make the hair quality worse and worse, making the hair more and more oily.

This type of shampoo contains lauric acid, palmitic acid, myristic acid, sodium hydroxide (potassium), etc. in the formula list because these ingredients are soap ingredients. The formula will produce saponification reaction, so it is also called soap-based shampoo.

Here is a brief introduction to the lauric acid, palmitic acid, and myristic acid in the soap-based shampoo formula:

Lauric acid:

Also known as dodecanoic acid, white needle-shaped crystals, slightly scented with laurel oil, insoluble Soluble in water, soluble in methanol, ether, chloroform and other organic solvents, slightly soluble in acetone and petroleum ether. Lauric acid is most widely used in the surfactant industry and is one of the main ingredients in soap. Typical amphiphilic molecules have completely different affinities at the head and tail ends. They are raw materials for the production of soaps, detergents, cosmetic surfactants and chemical fiber oils.

Palmitic acid:

Also known as hexadecanoic acid, white solid, insoluble in water, slightly soluble in Petroleum ether, soluble in ethanol, easily soluble in ether, chloroform and acetic acid. Used as a precipitant, chemical reagent and waterproofing agent; palmitic acid is used to produce odorless chloramphenicol and various palmitic acid metal salts, and can be used as an emulsifier in emulsion polymerization. The sodium or potassium salt of hexadecanoic acid can be used as An emulsifier during emulsion polymerization, the sodium salt of palmitic acid is one of the main components of soap.

Myristic acid:

Also known as myristic acid, it is a white to yellowish-white hard solid. , sometimes as a shiny crystalline solid, or as a white to yellowish-white powder, odorless. Insoluble in water, soluble in anhydrous ethanol, methanol, ether, petroleum ether, benzene and chloroform. It is mainly used as a raw material for the production of surfactants, and is used as a raw material for soaps, soaps, detergents, cosmetic surfactants and chemical fiber oils.
