polypropylene glycol include dipropylene glycol and polypropylene glycol having a molecular weight of 200 to 1000 e g polypropylene glycol 400 other satisfactory glycol ethers are ethylene glycol monobutyl ether butyl cellosolve diethylene glycol monobutyl ether butyl carbitol triethylene glycol monobutyl ether mono di tri propylene glycol monobutyl ether tetraethylene glycol monobutyl ether propylene glycol tertiary butyl ether ethylene glycol monoacetate and dipropylene glycol propionate the composition also contains an inorganic or organic salt or oxide of a multivalent metal cation particularly mg the metal salt or oxide provides several benefits including improved cleaning performance in dilute usage particularly in soft water areas and minimized amounts of perfume required to obtain the microemulsion state magnesium sulfate either anhydrous or hydrated e g heptahydrate is especially preferred as the magnesium salt good results also have been obtained with magnesium oxide magnesium chloride magnesium acetate magnesium propionate and magnesium hydroxide these magnesium salts can be used with formulations at neutral or acidic ph since magnesium hydroxide will not precipitate at these ph levels although magnesium is the preferred multivalent metal from which the salts inclusive of the oxide and hydroxide are formed other polyvalent metal ions also can be used provided that their salts are nontoxic and are soluble in the aqueous phase of.
