Description

Washing soap

Technical Field

The invention relates to a plant extract washing soap, and belongs to the technical field of soap making.

Background

Soap is a traditional cleaning product. The soap can be dissolved in water, and has effects of cleaning and decontaminating. The soap is one of soaps, people usually wash face or bath, but the pH value of the common soap is close to 9, the skin is dry after the soap is used, particularly in autumn and winter, neutral skin or dry skin is dry originally, skin peeling phenomenon can even occur after the soap is used, meanwhile, itching feeling is accompanied, skin moistening cream has to be frequently used by the people, most of the skin moistening cream is oily, body moistening cream can be adhered to clothes or a quilt, discomfort can be caused, and life of people is not changed. Therefore, there is a need to provide a detergent soap having a pH closer to that of the human body to improve the problem of skin irritation of the existing detergent soaps.

With the improvement of living standard and the rejection of various infectious diseases, people not only need to remove dirt, but also choose antibacterial soap for washing in daily life to prevent the pollution and the invasion of germs.

For example, when babies wash clothes, the babies often rub various stains such as milk stains, rice stains, soup stains, urine stains and the like due to the movement of the babies, and certain various bacteria can be bred, so that the soap for washing the clothes for the babies is expected to have certain sterilization and bacteriostasis functions while removing dirt.

There are two types of bacteriostatic soaps commercially available. One is a sulfur soap added with sulfur, but has peculiar unpleasant taste of sulfur, and the residual taste is not easy to disappear after use, which affects the popularization and use thereof. The other is soap added with triclocarban or triclosan, but a plurality of animal studies show that the triclocarban or triclosan has an influence on reproductive health at high concentration, so the SCCS of European Union consumer safety science committee publishes a preliminary evaluation comment SCCS/1643/22 about the cosmetic preservative triclocarban and triclosan, and the main content in the comment is limiting the maximum use concentration when the triclocarban or triclosan is used as the preservative. Experts in the U.S. food and drug administration have given warnings: "triclosan in antibacterial soaps can disturb the secretion of hormones from the human body; in addition, long-term exposure, or long-term use of chemical components of antibacterial soaps, or increased antibiotic resistance. "it is known that the production of this class of antibacterial soaps has been banned in some parts of the united states today.

In summary, the disadvantages of conventional toilet soaps have led to their gradual replacement by other products with skin care properties. It would also be desirable to have a skin cleansing bar that is not harmful to the human body, particularly a multi-functional bar, while providing other properties.
