In 1977, a handmade soap manufacturer named Robert Taylor invented a product similar to hand sanitizer, that is, put the hand sanitizer in a beautiful disposable container and add a pressing pump to it. After being put on the market, it was welcomed.
At the end of 1979, Taylor designed a smaller bottle and lower price for this product named "soft soap", and sold it as a daily necessity in grocery stores and pharmacies. In addition, he insisted that it be put together with the bar soap, so that customers understand that it can replace the unsightly traditional soap bar.
This passage is going to talk about the following questions of hand sanitizer:
(1)What is hand sanitizer?
(2)How to use hand sanitizer?
(3)Types of hand sanitizer
Hand sanitizer is a skin care cleanser used to clean hands. It uses mechanical friction and surfactants to remove dirt and attached bacteria from hands with or without water.
How to use hand sanitizer? To use hand sanitizer, first fully moisten your hands with clean water. Take an appropriate amount of hand sanitizer and rub your palms and hands for at least 30 seconds.
In this process, be careful to rub the fingertips and finger joints, and allow the foam to cover all parts of the hand, and rinse with running water after rubbing. Finally, pay attention to dry with a clean dry towel or paper towel. It is best not to dry, because the rapid evaporation of surface water will cause partial dehydration of the skin, causing the skin to dry and become rough.
There are many kinds of hand sanitizers.
1. Hand sanitizer with anti-bacterial effect
Studies have proved that most diseases are "hand-in", and many pathogens are delivered into the mouth by hand, or through contact with hands, nose, eyes, etc. Hand washing has become an effective way to prevent diseases.
This type of product mainly uses trichlorohydroxydiphenyl ether (DP300), 4-chloro-3, 5-xylenol (PCMX), trichlorostilbene (TCC) and o-phenylphenol (OPP) as anti-/ Antibacterial ingredients.
2. Children's hand sanitizer
Children's hand sanitizers must be made of non-toxic, non-irritating, and low-irritating raw materials, and minimize the number of pigments and flavors. Some green surfactants such as alkyl glycosides and amino acid surfactants are often used in children’s hand sanitizers in.
3. Industrial hand sanitizer
Workers engaged in machine repair, oil extraction, ink, printing, chemical, food processing and other industries often have heavy oil stains on their hands, and hand sanitizers that require heavy oil stains should have the characteristics of safety, strong washing ability, and low irritation.
4. Water-free hand sanitizer
Water-free hand sanitizer is mainly used in places where there is no water source and saves water. It is used for sterilization and hand washing functions. It does not require water to keep hands clean and hygienic.
5. Hospital hand sanitizer
There are two main types of hand sanitizers often used in hospitals. One type is anti-bacterial hand sanitizer, and the other is hand sanitizer disinfection products used under specific conditions such as surgery and blood draw. This type of product is basically No anionic surfactant is added.
Hand sanitizers, shower gels, and soaps are all alkaline substances. Because the sweat secreted by the human body is acidic, coupled with the inorganic salts precipitated with sweat and the oil secreted on the skin surface, the dirt on the skin will be acidic, so clean Supplies will be made alkaline.
The hand sanitizer is free of phosphorus, aluminum, alkali, sodium alkylbenzene sulfonate and other ingredients. It adopts the principle of gentle decontamination and is easily accepted by the skin. Hand sanitizers are alkaline, so people with skin allergies should not use hand sanitizer to wash their hands.
