  • the product is a liquid it may be a dilutable composition or an auto-dose composition.
  • An auto-dose composition is one which is contained within a cartridge or such like and dispensed from within the washing machine when required.
  • the product is a dilutable it means that the consumer can purchase a concentrated product and take the concentrate home where it can be diluted to form a regular home care product.
  • the dilution may require anything from 1 to 10 parts water to one part concentrate.
  • a composition of the invention may contain further optional ingredients to enhance performance and/or consumer acceptability.
