Soy Lecithin, E322, CAS no.8002-43-5, a mixture of phospholipids in oil, manufactured through water degumming the extracted oil of soybean. Non-GMO Soy Lecithin appears as a yellow to brown viscous liquid. Soy Lecithin is used as an emulsifier, thickener, stabilizer, mild preservative, and moisturizer. As an emulsifier, it prevents separation from occurring in products such as peanut butter, chocolate, ice cream, and margarine. It can also be used in the baking of bread to improve the texture and size.

1.Product description
Name: Glutaraldehyde 50%
CAS NO. 111-30-8
Appearance: colorless or yellowish clear and bright liquid
2.characteristics and applications
Glutaraldehyde is colorless or yellowish clear and bright liquid with slight irritating smell, and can be dissolved in organic dissolvent such as water, ether and ethanol.
In water solution, Glutaraldehyde doesn't exist much in free state; instead, Glutaraldehyde makes appearance as hydrates with different forms.and most of them are hydrates with annular structure.
Glutaraldehyde is reactive in property, and liable to polymerize and oxidize, which will react with compounds containing active oxygen and nitrogen. The reaction of the product with protein is mainly carried out between the carbonyl group of the former and the amino group of the latter. Among the known aldehydes, the product is one of the best cross-linking agents for proteins.
Glutaraldehyde has a small influence on the activity of enzyme, and most of enzymes can be fixed under controlled condition, to cross-link without losing their activity. Contrbuting to its outstanding characteristics, the product has drawn special concern from people and been put at broad application.
Magnesium chloride is a chloride chemical formula MgCl2 colorless and easily deliquescent crystal soluble in water Magnesium chloride hydrate can be extracted from brine or seawater usually with 6 molecules of crystal water but it loses crystal water when heated to 95C begins to decompose when it is above 135C and releases hydrogen chloride HCl gas
