Hair lotion is an emulsified product of oil-water system, which is a light oil Hair care cosmetics contain both oil and moisture, so they have the effect of the oily component giving luster and moisture to the hair, and the moisture imparting the effect of softening the hair and preventing breakage. Hair cream not only moisturizes and softens hair, but also helps to style it.

1. Types of hair cream:

It can be divided into O/W type hair cream and W/O type hair cream

O/W type hair cream is an oil-in-water hair cream. Its outer phase is moisture, which first moisturizes the hair. The oil separated out after demulsification forms an oily film on the hair, which plays a role in maintaining moisture in the hair, making the hair soft, smooth, natural-looking, and easy to comb and shape. The raw materials for hair emulsion include oil phase raw materials, water phase raw materials, emulsifiers and other additives.

Oil phase raw materials mainly include beeswax, petroleum jelly, white oil, olive oil, castor oil, lanolin and its derivatives, squalane, silicone oil, high-grade Fatty acids and their esters such as stearic acid, myristic acid, isopropyl myristate, etc., higher alcohols (cetyl alcohol, stearyl alcohol), etc.

W/O type hair cream is a water-in-oil hair cream. Its outer phase is oil, so when applied to the hair, it can make the hair shiny and lasting. It is more moisturizing for hair than O/W type hair cream, but it feels slightly greasy, and its effect on hair combing and shaping is not as good as O/W type hair cream. The raw materials of W/O type hair cream are basically the same as those of O/W type, but the combination and dosage of components in the formula are different.

Generally speaking, the stability of W/O type is worse than that of O/W type. However, in recent years, there has been a lot of progress in the development of raw materials for nonionic emulsifiers. Great progress has greatly improved the stability of W/O hair cream.
