The long hydrocarbon chains are non-polar (and hydrophobic) repelled by water and the salt end molecules are ionic (and hydrophilic) water soluble. Soaps differ according to the type of fatty acid and length of the carbon chain and according to the alkali employed. Fatty acids with longer chains are insoluble. If sodium hydroxide is used as the alkali, hard soaps are formed; Potassium hydroxide yields soft soaps. Soap salts are used as insecticides, herbicides, fungicides and algaecides. The lipophilic carbon chains infiltrate and destroy the lipoprotein matrix of the insect's cell membranes. Food grade soap salts are used also as general purpose food additives. Aluminum, calcium, magnesium, lead, zinc or other metals are used in place of sodium or potassium for soaps to be used in industry. Metallic salts of fatty acids are used as stabilizer and plasticizer in plastic industry as well as in cosmetics. They are used as flatting and sanding agents in lacquers, coatings & inks. They can be applied in tablet manufacturing. They are used as drying lubricants and dusting agents for rubbers. They are used as catalysts in chemical synthesis and emulsifiers for emulsion polymerization of synthetic rubber and resin which can be approved for use in food contact applications. They are used as waterproofing additives and ointments.Sales specificationAppearanceWhite powderLead content 20.0 +- 1.0%Free fatty acid1.0% maxWater1.0% maxParticle size99.0% (200 mesh)Melting point>; 200cTransportationPacking 25kgs in bagHazard class 6.1 (packing group: Iii)Un no. 1564.Country:South Korea/手机联系方式Co:Dyne Chemical Co., Ltd.Add:#922 Hyundai World Tower, 907, Mok-Dong, Yangchun-Gu, SeoulTel:82-2-66781114Fax:82-2-66781118Email:dynechem@chollian.netMobile:82-173512621LinkMan:Mr. Young S.
