Disinfection ingredient: hydrogen peroxide or alcohol

In the large family of hand sanitizers, disposable hand sanitizers do not require towels, water and soap, and can be disinfected and cleaned by spraying. Today, the whole society advocates "saving water resources" and "protecting the environment". Disposable hand sanitizers can effectively save valuable water resources.

There are two common formulas of no-clean hand sanitizers: one is hydrogen peroxide + active colloidal silver ions; the other is 75% ethanol (medical alcohol) + 2% propylene glycol (medical glycerin). Ethanol can disinfect and glycerin can moisturize. The role of skin care. The hands-free hand sanitizer containing hydrogen peroxide + active colloidal silver ions has a sterilization rate of 99.99% against more than 200 bacteria such as E. coli, Staphylococcus aureus, Candida albicans, and Pseudomonas aeruginosa. 75% ethanol has a bactericidal effect, and its homologue propylene glycol also has a certain bactericidal effect, and propylene glycol is not harmful to the human body and can also emollient the skin. These ingredients can kill bacteria on the hands, but they are easily volatile and have no washing effect.

There are antibacterial (antibacterial) hand sanitizers on the market. In addition to surfactants, disinfectants are added to the formula to reduce or inhibit the growth of microorganisms. At present, there are dozens of disinfectants that can be applied to antibacterial (antibacterial) hand sanitizers, but the safety of some disinfectants needs further research, which may cause such as dermatitis, allergic reactions, skin absorption and toxicity, and resistance to disinfectants. And other adverse reactions.

Experts point out that disinfection and sterilization are two concepts. Disinfection refers to the lethal effect on the propagation of pathogenic microorganisms, but it cannot kill all microorganisms such as spores. Therefore, disinfection is incomplete and cannot replace sterilization. Pathogens are killed without leaving, disinfection is the suppression of firepower, reducing the number of pathogens, reducing their vitality and transmission.

American Cleaning Association Brian Sansoni believes that washing hands with soap and water is the best disinfection method, and hand soap only supplements and cannot replace traditional soap. Dr. Glatt reminded that no matter what kind of hands you wash, you must first fully soak your hands and carefully scrub them for 20 ~ 30 seconds. When using hand sanitizer, always rub the front and back of your hand, finger joints, nails, etc. until the hand sanitizer is completely dry before rinsing.

Basic ingredients: Surfactant

Compared with the chemical components of disinfection and sterilization, the most important raw material in hand sanitizer is actually the surfactant. Its basic function is to remove oil and dirt on the hands. The normal usage is 15% -25%. Recently, with the surge in demand for various disinfectant solutions and germicidal hand sanitizers, there has also been a shortage of surfactants.

Zanyu Technology Group Co., Ltd. is one of the largest and most competitive surfactant suppliers in China. It currently has an annual production capacity of 700,000 tons of surfactants, and its domestic market share of anionic surfactant products exceeds 30%. Its surface active products such as AES, AOS, sulfonic acid, and MES have good decontamination, foaming, dispersing, emulsifying, wetting and other characteristics, so they are widely used in washing, washing, cleaning and daily necessities. In order to cope with and support the fight against the epidemic, the company's existing 8 surfactant factories are fully loaded during the Spring Festival, and are fully committed to ensuring the supply of raw materials such as disinfectant and hand sanitizer.

It is reported that the 100,000-ton-per-year liquid detergent project implemented by Zanyu Technology in Zhenjiang, Jiangsu has been completed and put into operation at the end of 2019; at the same time, the Zanyu Science and Technology Central Plains Daily Chemical Ecological Industrial Park project implemented in Hebi, Henan, some of which are planned for 2020 Built and put into operation within the year.

Previously, in addition to planning new construction and reorganizing the production capacity of surfactants, Zanyu Technology also planned downstream processing and production of daily chemical cleaning products in Zhenjiang, Jiangsu and Hebi, Henan. It is hoped that the company will gradually expand to Japan through a moderate industrial chain extension. The field of consumer goods. On February 1, the company also donated 1,600 boxes of 32,000 bottles of hand sanitizer to Wuhan.
