Everyone has a heart for beauty, and the research on cosmetics has never stopped since ancient times. As we all know, cosmetics have the functions of whitening, moisturizing, and moisturizing. These functions are attributed to the effects of various effective ingredients. Most of them are oil or nutrient ingredients, which are very susceptible to microbial infection and spoilage, resulting in deterioration of product quality. Preservatives are substances that can prevent the growth of microorganisms in the product. In cosmetics, the role of preservatives is to prevent the product from being contaminated by microorganisms, extend the shelf life of the product, and ensure the safety of the product.

Oxidative bactericidal algicide is a biocide with strong oxidizing properties, usually a strong oxidant, which has a strong killing effect on microorganisms in the water. Oxidizing biocides can oxidize other reducing substances in the water. When organic matter, hydrogen sulfide, and ferrous ions are present in the water, some of the oxidizing biocides will be consumed, reducing their biocidal effect.

On May 11, data released by the National Bureau of Statistics showed that in April 2021, the national factory prices for industrial producers increased by 6.8% year-on-year and 0.9% month-on-month; the purchasing prices of industrial producers increased by 9.0% year-on-year and 1.3% month-on-month. . On average from January to April, the ex-factory prices for industrial producers rose by 3.3% over the same period last year, and the purchasing prices for industrial producers rose by 4.3%. Among them, the prices of chemical raw materials and chemical products manufacturing increased by 17.5% year-on-year and 2.1% month-on-month.

Papermaking fungicide is an efficient, broad-spectrum, low-toxic compound fungicide product.

GB/T 26367-2010 Hygienic Standard for Guanidine Disinfectants This standard is applicable to disinfectants that use chlorhexidine acetate, chlorhexidine gluconate or polyhexamethylene biguanide as the bactericidal ingredients, and ethanol and/or water as the solvent;

The microbiological indicators, microbiological indicators, test bacteria suspension concentration, and detection time of the two types of wet wipes are quite different. Compared with sanitary wipes, the testing requirements/test indicators of disinfection wipes are more stringent, which is more effective for disinfection. The choice and amount of agent are more cautious.

In 1990, Collier and Ramsey synthesized a new type of isothiazolone compound, 1,2-benzisothiazolin-3-one (BIT), which was successfully marketed by Imperial Chemical Company of the United States. This compound is mainly used as a broad-spectrum in-tank anticorrosion. Agent,

When using IPBC, we need to pay attention to:

There are two ways of action of fungicides: one is a protective fungicide, and the other is a systemic fungicide.

Reasons for wood corruption: The main components of wood are cellulose, hemicellulose polysaccharides and lignin. Wood decay includes the fungus, insect pests and discoloration of wood, mainly because the main components such as polysaccharides and lignin in the wood become a hotbed of bacteria and insects under the action of water and air, and a series of changes have taken place.
