Underwear soap, as the name suggests, is a bar of hard soap used to clean underwear. It has the functions of inhibiting bacteria, deodorizing, removing blood stains and milk stains on underwear, and maintaining the cleanliness of underwear. Especially in the hot summer, the high temperature will speed up the secretion of body oil and sweat, which undoubtedly provides favorable conditions for the reproduction and growth of fungi and bacteria. During the special period of women, such as menstruation and pregnancy, underwear will inevitably be contaminated with blood stains and milk stains, which are difficult to remove with ordinary soap. The cleanliness of underwear for a certain period of time can effectively reduce the reproduction of bacteria and fungi, and protect the physiological health of private parts and skin.

Various components in the present invention are as follows:

Rosemary is a precious natural spice plant, which emits a fragrant smell. It can be used to increase the fragrance of underwear soaps. It can be used as a raw material for the preparation of air cleaners, perfumes, soaps, etc. . In addition, rosemary has a good disinfection and sterilization effect, which can be used to purify the air and prevent the spread of diseases. As a new generation of pure natural antioxidants, rosemary does not have the toxic side effects of synthetic antioxidants and the shortcomings of high temperature decomposition. Toxicological experiments and high-temperature frying experiments proved that the substance has the characteristics of safety, high efficiency, heat resistance and broad spectrum. The antibacterial test of rosemary ethanol extract showed that rosemary extract had significant inhibitory effect on Escherichia coli, Staphylococcus aureus and other bacteria, fungi and mold spores. And, using an organic solvent as an extraction solvent, the active substance of rosemary is dissolved. Taking into account the factors of safety, effectiveness and economy, ethanol is used as the organic solvent for the extraction of rosemary. The extraction process has high extraction rate and good stability, and can extract various antioxidant components in rosemary. The method is safe, effective, environmentally friendly, easy to operate and relatively low in cost. Moreover, the main component of the ethanol-extracted rosemary extract is rosmarinic acid, which has strong antioxidant, anti-inflammatory, antibacterial, antiviral, anticancer and antitumor effects. Rosmarinic acid also has broad-spectrum antimicrobial activity, and has a significant inhibitory effect on bacteria, fungi and mold spores such as Escherichia coli and Staphylococcus aureus.

Sophora flavescens can be used to kill insects, prevent vaginal swelling and pruritus, eczema, eczema, skin itching and other diseases, and has strong antibacterial effect.

P100 Alkaline Protease can hydrolyze proteins into soluble peptide bonds, which are then broken down into amino acids, so that stains can be easily removed. Due to the degradation into soluble small molecular substances or substances that are easily dispersed in the washing liquid, the adsorbed protein dirt is reduced, and the dirt that was firmly adsorbed on the fibers in the presence of protein is also easier to remove. Alkaline protease can not only hydrolyze peptide bonds, but also hydrolyze amide bonds, ester bonds, and transesterification and transpeptide functions. Alkaline protease can partially destroy the structure of protein, separate the material components, and promote the removal of various stains.

Surfactants are a class of surface-active compounds. After being dissolved in liquid (especially water), it can significantly reduce the surface tension or interfacial tension of the solution, and can improve the solubilization, emulsification, dispersion, penetration, wetting, foaming and cleaning capabilities of the solution. Surfactants have a common feature, that is, there are both hydrophilic groups and lipophilic groups (also known as hydrophobic groups) in the molecule. Change the interface properties between the two-phase substances, can play the role of wetting, penetration, cleaning, dispersion, emulsification, solubilization, foaming, defoaming and so on. Anionic surfactants can be dissociated into anions and cations in water, and the anions play a role in reducing surface tension. Generally, it is a salt formed by a hydrophobic anion and a hydrophilic cation. Amino acid foaming agent ECS-22SB has a mild and refreshing skin feel, and has a good skin nourishing effect.

In the preparation process, the green tea extract is directly used to dissolve NaOH instead of distilled water.
