Abstract
A scented aqueous thixotropic dishwasher composition comprising tripolyphosphate, a chlorine bleach compound, a thixotropic thickener, a chlorine bleach stable fragrance and air in an amount of 2% to 10% by volume. The composition preferably also contains a long chain fatty acid or its salt, an organic detergent active material, a foam depressant and an alkali metal carbonate. Also disclosed is a process for preparing aqueous thixotropic dishwater detergent compositions having improved physical stability by entraining air into the composition in an amount such that the bulk and liquid phase specific gravities of the dishwasher detergent composition are approximately equal.
