ABSTRACT:
We have found that long standing problems relating to the stability of organic materials in alkaline detergents, including the reversion or hydrolysis of condensed phosphate sequestrants in alkaline solid detergent compositions can be alleviated by the use of an organic composition having vicinal hydroxyls. Such a solid block detergent can be manufactured by a process in which a source of alkalinity, a functional material including a condensed phosphate sequestering agent, an organic compound having two vicinal hydroxyl groups, are combined in a pourable composition or liquid. Such a liquid can be introduced into a plastic capsule and solidified. During manufacture and solidification, we have found that the vicinal hydroxyl compound prevents substantial hydrolysis or reversion of the condensed phosphate maintaining effective hardness ion sequestration during the use of the detergent. The stabilizer can also stabilizes color, chlorine content and dispensing properties.
