About Hand Sanitizer
Hand sanitizer is a kind of skin care cleaning liquid that mainly cleans the hands. It uses mechanical friction and surfactant to cooperate with the water flow to remove dirt and attached bacteria on the hands.
The chemicals in the hand sanitizer may irritate the skin of the hands and people who are allergic to the skin are not suitable for use. It is recommended to apply hand cream after washing, which is generally harmless.
Points Of Hand Sanitizer
(1) The purpose of hand washing is to remove the stains and bacteria on the hand, so the cleaning power is the first consideration, but the cleaning power and the degreasing power are proportional, and the excellent detergency is accompanied by a strong degreasing effect , Should choose mild non-irritating surfactant.
(2) Rich and long-lasting foam and easy-to-rinse are important indicators of the quality of hand sanitizer products. Rich and durable foam is easy to wash, which can bring users an easy experience of washing hands without burden, so focus on formula design Consider foaming and foam stabilizing properties and easy flushing.
(3) The ability to remove bacteria is the key to achieving true cleanliness in hand washing, and is the reason why it is mainly used in public places as a hand sanitizer.
Types Of Hand Sanitizer
(1) Common hand sanitizer: the role of cleaning and decontamination.
(2) Heavy oil-stained hand sanitizer: the cleaning of industrial oils (such as engine oil, gasoline, butter, diesel, etc.) and stubborn stains.
(3) Children's hand sanitizer: Children's hand sanitizer must use non-toxic, non-irritating / low-irritating raw materials, and the amount of pigments and fragrances should be reduced as much as possible. Some green surfactants such as alkyl glycosides, amino acid surfactants and plant-based emollients are often used in children's hand sanitizers.
(4) Water-free hand lotion
Another type of this type of product is the use of guanidine cationic bactericides and adjuvants, mainly for daily sterilization of skin on hands. Spray directly on the hand when using.

(6) Hand sanitizer for hospital
There are two main types of hand sanitizers commonly used in hospitals. One is a hand sanitizer that has the effect of removing bacteria, and the other is a hand sanitizer disinfection product that is used under specific conditions before surgery and blood drawing. This kind of product is basically free of anions. Surfactant, mainly composed of double-chain quaternary ammonium salt with bactericidal effect, chlorhexidine gluconate, chlorhexidine acetate, chlorhexidine gluconate, diclofenac gluconate, benzalkonium chloride, It consists of ethanol, isopropanol, polyhexamethylene biguanide and additives.
Different hand sanitizers have differences on the outer packaging. Ordinary hand sanitizers are generally "precision font size", while disinfectant hand sanitizers are mostly "small font size".
Hand sanitizer is generally free of phosphorus, aluminum, alkali, sodium alkylbenzene sulfonate and other ingredients. It adopts the principle of mild decontamination and is easily accepted by the skin.
How To Use Hand Sanitizer?
First moisten your hands thoroughly with clean water, take an appropriate amount of hand sanitizer on your palms, and rub at least
For more than 30 seconds, during this process, pay attention to rubbing to the fingertips and finger joints, and allow the foam to cover all parts of the entire hand. After rubbing, rinse with running water. 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 become dry and rough.
Many toilets in restaurants, shopping malls, toilets, and other public places provide free hand sanitizer, which is also convenient for people to ask: Will these free hand sanitizers hurt the skin? In fact, even small bottles of hand sanitizer purchased at home may There are quality problems such as excessive bacteria and poor emulsification effect. China has promulgated the industry standard for hand sanitizer products as QB2654-2004 "Hand Sanitizer"
Elements Of Hand Sanitizer
(1) Decontamination ingredients
Decontamination ingredients are to provide decontamination and rich foam, mainly anionic surfactants and a small amount of non-ionic and zwitterionic surfactants. Anionic surfactants include soap, sodium lauryl sulfate, Q-olefin sulfonate, fatty alcohol polyoxyethylene ether sulfate, Q-sulfo fatty acid ester, lauroyl sarcosinate and monooleic acid amide sulfo Disodium succinate, etc. Soap and sodium lauryl sulfate are the earliest surfactants used in hand sanitizers. Due to their respective deficiencies such as strong degreasing, high soap pH and low resistance to hard water, the calcium soap formed is less used.
Non-ionic surfactants are generally less used in hand sanitizers. The addition of a small amount can improve the detergency and improve the stability of the foam, such as coconut acid diethanolamide, in which the addition of alkyl glycosides can reduce the surfactant Skin irritation. The addition of a small amount of zwitterions is beneficial to the long-term foaming and foaming, betaine and amine oxide.
(2) Nursing ingredients
When washing hands, due to the degreasing effect of the surfactant, the skin feels dry after hand washing. Therefore, some fat-rich agents and emollients should be added to supplement the skin oil to prevent dry and rough skin. Propylene glycol, sorbitol, lactate, sodium pyrrolidone carboxylate, etc.
(3) Sensory adjustment ingredients
In order to allow consumers to prefer and accept hand sanitizer, give the hand sanitizer a special effect and appearance, add dye or pearlescent agent; add a thickener to adjust a suitable viscosity for easy access; in order to have a kind of Add the right amount of fragrance for a relaxed and pleasant feeling.
(4) Natural ingredients
As people's awareness of safety and environmental protection increases, green natural products are more admired. Therefore, adding natural raw materials to hand sanitizer formulations is the choice of many hand sanitizer brands. These natural additives serve to reduce irritation, moisturize the skin, and provide natural fragrance and The role of color, such as various plants, Chinese herbal medicines, fruit extracts, aloe, ginkgo, chrysanthemum, ginseng, Tianqi, licorice, peony peel, tea fruit and lemon, etc.
How To Choose A Good Hand Sanitizer?
1. To go to regular shopping malls, the purchase channels of regular shopping malls are relatively stable, and there are more strict purchase control systems.
2. Observe whether the packaging is intact, whether the printing on the bottle is clear, and whether the pump head is strong. Generally, the hand sanitizer is squeezed out of the pump head. If the packaging quality is poor, there will be no liquid or leakage during use, causing inconvenience and waste.
3. To see if the signs are complete, if there is no factory name, factory address, etc., pay special attention to whether there is a standard number. Although there is no unified national standard for hand sanitizer, the state does not allow non-standard production, so each production enterprise should formulate enterprise standards and indicate the enterprise standard number on the packaging to ensure product quality.
4. Pay attention to the contents, that is, the hand sanitizer itself, and smell if it smells, pungent, etc. If it is, it may be that the warranty period has expired, or the banned raw materials are used, it is best not to buy and use. Also observe whether there is stratification or oil-water separation phenomenon, if there is, it indicates that the emulsification process is not well controlled in the production process, which will affect the washing effect.
