Contact the supplierIt can be seen from the foregoing discussion that fatty acids are an important factor, in the present production of high quality soaps. The wide variation possible in properties of soaps made from them and their rapid and complete reaction with alkali give them advantages over fats and oils in many applications. With improvements in fatty acid processing still being made, it is to be expected ...
Contact the supplierMetal Soaps (Calcium and Zinc Stearate) Soaps are compounds of metals with fatty acids derived from vegetable oils or animal tallow, the most common acid used being stearic acid, which contains mostly C16 and C18 chains in its industrial form. The main metals used are sodium, potassium, calcium, magnesium, zinc and aluminium.
Contact the supplierFatty acids are classified in many ways: by length, by saturation vs unsaturation, by even vs odd carbon content, and by linear vs branched. Length of fatty acids. Short-chain fatty acids (SCFA) are fatty acids with aliphatic tails of five or fewer carbons (e.g. butyric acid).; Medium-chain fatty acids (MCFA) are fatty acids with aliphatic tails of 6 to 12 carbons, which can form medium-chain ...

Contact the supplierInsecticidal soaps are potassium salts of fatty acids. A soap is made from the action of an alkali such as potassium hydroxide on a fat. Fats consist mainly of fatty acids. Commercial products contain a blend of selected fatty acid chain lengths. How do insecticidal soaps work? Insecticidal soaps work only on direct contact with the target pests.
Contact the supplierMar 19, 2015·The average percentage of myristic acid in the favorite soap recipes of soapmakers polled rounds in at 7%. Most recipes clocked in at 4% to 7% myristic acid, but there were a few outliers with slightly higher percentages of myristic acid.
