(1) The purpose of hand washing is to remove the stains and bacteria on the hands. Therefore, the detergency is the first consideration, but the detergency and degreasing power are proportional, and the excellent detergency is accompanied by a strong degreasing effect. , Should choose mild non-irritating surfactants.
(2) Rich and long-lasting foam and easy washing are important indicators of the quality of hand sanitizer products. The rich and long-lasting foam is easy to wash, which can bring users a relaxing experience of washing hands without burden. Therefore, we should focus on formula design Consider foaming and foam stabilization performance and ease of washing.

Precious metal catalyst
A precious metal catalyst is a compound that can change the speed of a chemical reaction without participating in the reaction itself. The more commonly used are platinum, palladium, rhodium, silver, ruthenium, etc. None of their d electron orbitals are filled, the surface easily adsorbs reactants, and the strength is moderate, which is conducive to the formation of intermediate "active compounds". Noble metal catalysts are highly valued for their excellent activity, selectivity, and stability. They are widely used in reactions such as hydrogenation, dehydrogenation, oxidation, reduction, isomerization, aromatization, and cracking. The fields of chemical environmental protection and new energy play a very important role.
