NEW MATERIAL:A solid lactate shown by the formula (M is M, Na or NH4; m is in 2.4<=m<=5 when M is K or NH4; n is 0-5). EXAMPLE:Sodium calcium lactate double salt. USE:The titled lactate is added to foods, cosmetics and industrial chemicals and used. The lactate has low water absorption properties, is in solid, powdery or flaky state to be made into powder, readily blended with another powdery product and is extremely effective. The amount of sodium salt, potassium salt and ammonium salt can be changed and lactate double salt in a powdery state corresponding to purpose of use can be obtained. PREPARATION:1mol. calcium lactate is reacted with (i) sodium lactate in an amount of 2.4mol.<m<=5mol. or (ii) potassium lactate or ammonium lactate in an amount of 0mol.<m<=5mol. to give a compound shown by formula I. |
