Definitions

  • the present invention relates to the use of a liquid laundry detergent composition to minimize the adverse effects of rare accidental exposure of the detergent composition comprised with a liquid laundry detergent composition.
  • Laundry water-soluble unit dose articles are liked by consumers as they are efficient and convenient to use. They offer simple unit dosing of laundry detergent composition to be used in the laundry wash operation removing the need for inconvenient and messy dosing.
  • a liquid laundry detergent composition according to the present invention comprised within a water-soluble unit dose article provided a desired reduction in adverse effects from rare accidental exposures to the contents of the water-soluble unit dose article whilst providing laundry cleaning, especially greasy food stain cleaning, and freshness benefits and still maintaining a good whiteness profile.
  • the present invention discloses the use of a liquid laundry detergent composition comprised in a water-soluble unit dose article to provide laundry cleaning benefits and to minimize potential adverse effects associated with accidental exposure to said liquid laundry detergent composition contained within the water-soluble unit dose article, wherein the liquid laundry detergent composition comprises less than 10% by weight of the liquid laundry detergent composition of a fatty alcohol ethoxylate non-ionic surfactant.
  • the present invention is to the use of a liquid laundry detergent composition comprised in a water-soluble unit dose article to provide laundry cleaning benefits and to minimize potential adverse effects associated with accidental exposure to said liquid laundry detergent composition contained within the water-soluble unit dose article.
  • water-soluble unit dose articles contain a single dose of a laundry detergent composition enveloped in a water-soluble film.
  • the consumer places the entire article into the drum of a washing machine or other wash receptacle together with fabrics to be washed.
  • the water-soluble film dissolves releasing the laundry detergent composition contained within into the water and into contact with the fabrics.
  • the concept is that the laundry detergent composition remains contained within the unit dose article until the unit dose article is contacted with water during use.
  • Irritation is herein defined as the production of changes to the body following the application of test chemical to the anterior surface of the body, which are fully reversible within 21 days of application.
  • eye irritation is defined as the production of changes in the eye following the application of test chemical to the anterior surface of the eye, which are fully reversible within 21 days of application.
  • the term is interchangeable with "Reversible effects on the Eye” and with "UN GHS Category 2" (4), and can be assessed following the OECD Guidelines for Testing of Chemicals, Test No. 438: Isolated Chicken Eye Test Method for Identifying i) Chemicals Inducing Serious Eye Damage and ii) Chemicals Not Requiring Classification for Eye Irritation or Serious Eye Damage (Adopted version : 26 July 2013).

However, upon addition of the water-soluble unit dose article to water, the water-soluble film dissolves and releases the contents of the internal compartment into the wash liquor.
  • the compartment should be understood as meaning a closed internal space within the unit dose article, which holds the liquid laundry detergent composition.
  • a first water-soluble film may be shaped to comprise an open compartment into which the liquid laundry detergent composition is added.
