Definitions

  • the present invention concerns a process for the preparation of encapsulated perfume in fabric softener compositions.
  • encapsulated perfume components in fabric conditioners is advantageous in that it enables the improved storage and delivery of perfumes and perfume components.
  • Such technologies provide enhanced fragrance delivery over conventional free perfume oil by overcoming the issue of perfume loss during the drying process by protecting the perfume in the capsule.
  • the encaps themselves are relatively fragile and contain volatile perfume components which are depleted if rupture of the encap casing occurs. Accordingly, in a typical method of manufacture, the encaps are introduced into the active mixture at a late stage of the process in order to preserve them. Typically, water and minor ingredients such as antifoam and preservative are heated whilst the softening active is melted separately. The molten active is then added to the hot water with agitation before being allowed to cool. Only then is the encapsulated perfume added to the mixture, along with any free perfume oil. Such a sequence of steps, with the addition of the encaps taking place after the addition of the molten active to the water phase, helps to preserve the fragile encaps and minimises damage to these relatively delicate components.
  • a process for preparing a composition comprising an ester- linked quaternary ammonium fabric softening active, an encapsulated perfume and a non-confined perfume, wherein the process comprises the step of dispersing the encapsulated perfume in water before the addition of the fabric softening active to the water, and wherein the composition is free from calcium chloride and benzalkonium chloride.
  • composition obtainable from the process of the first aspect of the invention.
  • the encapsulated perfume is added to the water phase, before the addition of the molten active.
  • the water phase may also contain minor components such as preservatives and antifoam.

  • a preferred process of the invention comprises the steps of:- 1) mixing perfume encaps, and optional minors such as preservatives and anti-foam, with heated water to form a water phase;
  • the molten active is added to the water phase, wherein the water phase contains perfume encapsulates. It is preferable that 100 % of the molten active is added at this stage, although the addition of a minor amount of molten active to the water phase before the encaps are added is also covered by the present invention.
  • minor amount is meant, for example, from 0.0001 to 25 %, for example 20, or 10 %.
  • Suitable fabric softening actives which may be used in the process and compositions of the present invention include cationic or non-ionic conditioning agents, but preferably they will be cationic.
