Definitions

  • a consumer product comprising a container and at least one water-soluble unit dose article wherein the container contains an adhesive strip comprising a perfume.
  • Water-soluble unit dose articles are liked by consumers as they offer convenience and ease to the laundry process.
  • the water-soluble unit dose article comprises a water-soluble film and a unitized dose of a laundry treatment composition which may be within one or more compartments within the unit dose article.
  • Such water-soluble unit dose articles are often sold to consumers in rigid or flexible recloseable containers.
  • Other detergent compositions such as free-flowing powders and free flowing liquid are also traditionally sold in rigid or flexible recloseable containers.
  • Such product forms have the benefit that upon opening the container the consumer can immediately smell the perfume material added as an ingredient to the cleaning composition. Consumers prefer such a 'perfume bloom' upon opening the container as it connotes the ability of the detergent to provide a fresh smell to the fabrics or surfaces cleaned with the detergent. Furthermore, the 'perfume bloom' can also prevent or reduce any malodor inside the container coming from a malodor generating ingredient in the detergent composition housed inside the container.
  • WO2008038189 discloses containers housing water-soluble unit dose articles and adhesive strips stuck to the interior of the container, e.g. substantially at the opening of said container.
  • the adhesive strip comprises perfumes such that when the consumer opens the container, they can smell perfumes released from the adhesive strip.
  • a consumer product comprising at least one water-soluble unit dose article and a container; wherein the container comprises an internal compartment wherein the internal compartment houses the at least one water-soluble unit dose article; and wherein the at least one water-soluble unit dose article comprises at least one water-soluble film and a detergent composition; wherein the container comprises a base, an opening, a lid moveable between an open position and a closed position and at least one wall and wherein the internal compartment is accessible via the opening; and wherein the opening is positioned opposite to the base, the at least one wall extends from the base to the opening; and wherein in the closed position the lid blocks access to the opening and in the open position the user has access to the opening; and wherein the base has an internal surface and an exterior surface and wherein the at least one wall has an internal surface and an exterior surface; and wherein the container comprises an adhesive strip stuck to the interior surface of the base, the interior surface of the at least one wall, or a mixture thereof, preferably to the base; and wherein, when stuck to the interior surface of the at least one wall

  • polyethylene glycol graft polymer comprising a polyethylene glycol backbone (Pluriol E6000) and hydrophobic vinyl acetate side chains, comprising 40% by weight of the polymer system of a polyethylene glycol backbone polymer and 60% by weight of the polymer system of the grafted vinyl acetate side chains.
  • Percentage weight loss data (Table 3) clearly show a decreased percentage weight loss when the adhesive strip is positioned at the bottom rather than at the top of the piled row of water soluble unit dose articles, perfume being released between 9% and 24% faster for the top versus the bottom positioning. The finding is consistent for both perfumed and nil perfume water soluble unit dose articles and across replicate tests. The decreased percentage weight loss when positioning the perfume comprising adhesive strip near the bottom of the holding container indicates a longer perfume long lasting potential relative to when the perfume comprising adhesive strip is positioned near the top of the container.
  • Perfume migration into water soluble unit dose articles was demonstrated through a GC-MS headspace analysis on nil perfume water soluble unit dose articles, by adding a 35 days aged water soluble unit dose article into an empty glass container (dimensions : 78 mm height, 49 mm diameter) and measuring with GC-MS the perfume components build up into the headspace after a 3 days storage test at 25°C / 60% relative humidity controlled conditions.
  • a reference nil perfume pouch not exposed to perfume comprising adhesive strip technology was also included to secure absence of false readings.
  • a higher perfume absorption was also detected the closer the unit dose articles were stored to the perfume comprising adhesive strip, as such also confirming accuracy and validity of the conclusions from the analytical testing.
