The role of silicone oil in shampoo

If according to the structure and function of conditioning agent, it can be divided into cationic surfactants, cationic polymers, lubricants, wetting agents, hydrolyzed collagen and protein, other conditioning agent.

Typically, while shampoo removing hair dirt, due to excessive remove the sebum which naturally secreted by scalp, will damage the hair, in addition, the adsorption of surfactants makes the hair tangled and difficult to comb. Now, most shampoos are conditioning shampoos, both have washing and conditioning effect. The role of shampoo conditioners make the hair does not tangle, easy to wet comb and dry comb, make the hair keep moist and have good retentivity on curlers, also make dry hair smooth, endowed with shiny and stereoscopic, good combing.

The role of shampoo is through conditioning agent deposited on the hair surface, and selectively retained in the hair, even if washing, also can be retain a considerable part of the sediment. This feature is known as "Substantivity". Different types of conditioning agents adsorbed on the hair by chemical adsorption, physical adsorption and ion adsorption, which is an important condition for conditioning agents functioning. Silicone emulsion is a new non-ionic silicone surfactants, HLB value is low, with automatic emulsifying characteristics. Therefore, the use of silicone emulsion is widely, in hair care products, shampoo, cosmetics material, cars, furniture, flooring, leather brightener, metal processing, plastics, polyurethane, rubber, glass, ceramic, stone, textile, paper, wood industries such as stripping, polishing, anti-sticking, rust, and other aspects of cleaning and waterproofing having great use. The following we will discuss the role and use of shampoo. First, the silicone emulsion solve the problem of the unsmooth feeling of hair contact with shampoo while wet combing (especially the hair in the semi-dry state). This unsmooth feeling will generally disappear in the beginning of hair drying, and show it clearly by noon or afternoon at the following day, then it has always existed, very unpleasing. This is currently a major flaw of shampoo.

Second, the formula requires loose, not harsh. Some silicone oils require adding in harsh conditions (very precise surfactants and the amount of cationic polymer), and the effect is not as good as silicone emulsion. To make the hair soft, there must be a specific molecular weight distribution of organic silicon act on the hair in certain circumstances, and over the years, we are researching on the "specific" condition. Particular cationic quaternary ammonium polymers also have a lasting and soft effect on hair, but the effect is much weaker than silicone oil. Only specific molecular weight distribution organosilicone can play super conditioning and soft feeling on hair, to pursuit the perfect hair feeling, organosilicone content must be strictly controlled. Foam was the most serious disturb the distribution of organosilicone on the hair.

Finally, silicone emulsion has a significant hair care effect, make the hair has a unique silky soft feel, soft and flexible, hair does not greasy, suitable for long-term used. Long-term use can make the hair has unique silky and soft, super clarity, and would not like other silicone oil, which only can make the hair soft at the first time use, after repeated use, the hair was hardened.
