Liquid detergent contains a lot of water and organic matter, which provides a good source of nutrients for the growth of microorganisms. If microbial contamination sources are accidentally introduced during processing, storage, and use, the rapid growth and reproduction of bacteria and fungi will not only cause product deterioration, but may also endanger the health of consumers. The use of preservatives can effectively prevent this phenomenon. In the choice of preservatives, any preservative has the characteristics of the best use conditions and use restrictions.

In vitro diagnostic reagents [1 The current development status of the industry is very similar to the development of the home appliance industry in the early 1990s: on the one hand, the market is large; on the other hand, the monopoly advantage of imported reagents and diagnostic equipment is being broken and restricted by national products. . "This is a summary of the development status of in vitro diagnostic reagents in my country by Wu Lebin, the president of Zhongsheng Beikong Biotechnology Co., Ltd.

The common types of microbial contamination in household care products include bacteria, molds and yeasts.

What is sterilization (sterilazation, sterilant)? Refers to the process of using strong physical and chemical factors to kill or remove all pathogenic and non-pathogenic microorganisms in the external environment, including bacterial spores and fungal spores. It is an absolute concept. The effect is expressed by the sterilization rate, generally ≥99.9999%.

Paint preservatives are characterized by high efficiency in killing bacteria, fungi, yeasts, and low dosage; good compatibility with paints, emulsions and other materials; easy to dilute with water, and easy to add paint, coatings and emulsions or In other similar materials; when pH≤9, it is stable.

Stability is the ability of in vitro diagnostic reagents to maintain the consistency of characteristics over time. It is a basic attribute that the reagent must have. It is an important indicator to ensure the effectiveness of the reagent during use, and it is also the responsibility of the manufacturer.

In today’s paper industry, due to the increasing shortage of available resources, the amount of waste paper recycled is increasing, and the recycling of white water systems is also increasing, which will increase the production of pulp; and neutral sizing technology is gradually being promoted and applied. In the alkaline system

IPBC has broad-spectrum antibacterial activity, especially for molds, yeasts and algae.

Bromine is a reddish brown liquid, easy to volatilize, it will condense into a solid at low temperature, and it will boil above 58.78°C. Once volatilized, it will produce reddish-brown gas, which has a stimulating effect on the human digestive tract, respiratory tract, and mucous membranes.

A few days ago, the China Market Supervision and Administration (National Standardization Administration) approved 450 recommended national standards and 4 national standard amendments. These include "Clean Dioxide Disinfectant Hygiene Requirements", "General Technical Requirements for Disinfectant Filling Production Lines", and "Guidelines for the Classification of Enzyme Preparations", both of which will be implemented on March 1, 2022.
