Abstract
An agglomerated dishwashing composition containing the following components: Sodium dichloroisocyanurate 0.5-10% dihydrate A polyphosphate having an 25-60% Na.sub.2 O or K.sub.2 O to P.sub.2 O.sub.5 ratio (anhydrous basis) of about 1:1 to 2:1 Sodium carbonate 0-60% (anhydrous basis) A sodium silicate having 10-15% a SiO.sub.2 to Na.sub.2 O ratio of (total silicate from about 2.40 to about solids) 3.22 Low-foaming chlorine- 1-10% compatible nonionic surfactant Water 5-20% The compositions exhibit lower chlorine loss than similar formulations containing commercial anhydrous sodium dichloroisocyanurate as the dry bleach component.
Claims5
An agglomerated dishwashing detergent composition containing by weight as its essential ingredients:
- Sodium dichloroisocyanurate 0.5-10% dihydrate A polyphosphate having an 25-60% Na.sub.2 O or K.sub.2 O to P.sub.2 O.sub.5 ratio (anhydrous basis) of about 1:1 to 2:1 Sodium carbonate 0-60% (anhydrous basis) A sodium silicate having a 10-15% SiO.sub.2 to Na.sub.2 O ratio of from (total silicate solids) about 2.40 to about 3.22 Low-foaming chlorine- 1-10% compatible nonionic surfactant Water 5-20%.
A process of preparing an agglomerated dishwashing detergent composition containing by weight as its essential ingredients:
- Sodium dichloroisocyanurate 0.5-10% dihydrate A polyphosphate having an 25-60% Na.sub.2 O or K.sub.2 O to P.sub.2 O.sub.5 ratio (anhydrous basis) of about 1:1 to 2:1 Sodium carbonate 0-60% (anhydrous basis) A sodium silicate having a 10-15% SiO.sub.2 to Na.sub.2 O ratio of from (total silicate solids) about 2.40 to about 3.22 Low-foaming chlorine- 1-10% compatible nonionic surfactant Water 5-20%
- comprising forming a homogeneous dry mixture of the water-free components and adding to the dry mixture with agitation sufficient water to induce agglomeration and insufficient to destroy the discrete particle characteristic of the mixture, the total amount of water in the finally agglomerated composition being in the numerical range aforesaid.
