The main purpose
Electroplating, dyes, flavors and fragrances and pharmaceuticals, etc. Brightener for zinc plating, grain refiner. Used in organic synthesis intermediates, dyeing mordants, fixing agents, preparation of spices or flavoring agents, flavor anti-volatile agents and galvanizing brighteners.
According to my country's GB2760-1996 regulations, benzylacetone is temporarily allowed to be used as a edible spice for the preparation of sweet pea, cocoa, nuts, cherries, fruits and other flavor flavors. It is also used as a modifier and anti-volatile agent for floral flavors. It has a stimulating effect on the skin and is generally not used in cosmetics. In addition, benzylidene acetone can also be used as a mordant, fixing agent and brightening agent for galvanizing in the dyeing industry. Brighteners are organic compounds that can produce brightening and leveling effects. Generally contain aromatic aldehydes or aromatic ketones and certain heterocyclic aldehydes, namely coumarin, vanillin, benzal acetone, etc., and its molecular structure contains a carbonyl group. As long as this structure remains unchanged, it replaces various substituents. Can produce many kinds of compounds with brightening effect. Among them, benzalacetone has the best effect. Most of these additives on the market in China are benzalacetone as the main brightener.
Benzarone acetone can be used as food flavoring, used to modulate fragrant flavors such as peas, cocoa, nuts, cherries, fruits and so on. It is also used as a flavoring agent and an anti volatile agent for flower flavors. It is generally not used in cosmetics because of its irritating effect on skin. In addition, benzylidene acetone can also be used as mordant, fixing agent and zinc plating brightener in dyeing industry.
