Description

Alkaline silicone oil-free shampoo and preparation process thereof

Technical Field

The invention belongs to the technical field of daily cosmetics, and particularly relates to alkaline silicone oil-free shampoo with an alkaline care effect and a preparation process thereof.

Background

Shampoo, also known as shampoo and shampoo, is a mixture containing various substances such as surfactant and the like, is a hair washing product which is most widely applied, and is one of the most commonly used hair cosmetics. It can be used for cleaning human body secreted oil, sweat scale, cells detached from scalp, foreign dust, microorganism, and residue and unpleasant odor of styling product, etc. attached to scalp and hair, and keeping scalp and hair clean and beautiful. Since silicone oil has good viscosity and ductility, and is very similar to oil substances extracted from natural plants, the silicone oil is applied to shampoo products along with the development of chemical industry and the increasing requirements of people on the shampoo products. When the hair washing agent is used for washing hair, the silicone oil can be adsorbed with the hair, unevenness caused by the raised hair scales is filled, mutual friction among the hair is reduced, the hair is easy to comb and has smoothness, and the damage of the hair is effectively relieved.

The traditional shampoo adopts silicone oil and cationic polymer as conditioning components, a part of silicone oil is deposited on hair to play a role when the hair is washed, and meanwhile, the shampoo has a cleaning function and can wash off a part of silicone oil. This process of depositing-washing away silicone oil is not always the same amount per use. Specifically, silicone oil deposits more and more on the hair with increasing use times, the hair feels more greasy than when initially used, and the hair hangs down without a voluminous feel. At the same time, the silicone oil deposits on the hair, which appears to be collapsed and without hair volume. While the silicone-free shampoo can avoid the problems, the shampoo without polysiloxane (such as polydimethylsiloxane, dimethiconol, amino-terminated dimethyl siloxane, phenyl trimethicone and the like) is the silicone-free shampoo. For people who like to have fluffy hair style due to thin and soft hair, or people who have short hair, thin hair, little hair amount and serious oil production, the shampoo without silicone oil can be selected to generate the relatively fluffy hair style effect.

Meanwhile, the oil can be quickly removed due to alkaline cleaning, and the oily hair can be cleaned after use. For oily hair, the hair is often oily, smooth, sticky and sticky, and alkaline silicone-free shampoo can be used, but the alkaline shampoo has good decontamination effect, but damages the hair, so that the hair scales are opened to become rough and are not easy to manage.
