  • perfume in this context is not only meant a fully formulated product fragrance, but also selected components of that fragrance, particularly those which are prone to loss, such as the so-called 'top notes'.
  • Top notes are defined by Poucher (Journal of the Society of Cosmetic Chemists 6(2):80 [1955]). Examples of well known top-notes include citrus oils, linalool, linalyl acetate, lavender, dihydromyrcenol, rose oxide and cis-3-hexanol. Top notes typically comprise 15-25%wt of a perfume composition and in those embodiments of the invention which contain an increased level of top-notes it is envisaged at that least 20%wt would be present within the encapsulate.

It is also advantageous to encapsulate perfume components which have a low Clog P (i.e. those which will be partitioned into water), preferably with a Clog P of less than 3.0. These materials, of relatively low boiling point and relatively low Clog P have been called the "delayed blooming" perfume ingredients and include the following materials:
  • Preferred non-encapsulated perfume ingredients are those hydrophobic perfume components with a ClogP above 3.
  • ClogP means the re
  • the octanol/water partition coefficient of a perfume raw material is the ratio between its equilibrium concentrations in octanol and water. Given that this measure is a ratio of the equilibrium concentration of a PRM in a non-polar solvent (octanol) with its concentration in a polar solvent (water), ClogP is also a measure of the hydrophobicity of a material-the higher the ClogP value, the more hydrophobic the material. ClogP values can be readily calculated from a program called "CLOGP" which is available from Daylight Chemical Information Systems Inc., Irvine Calif., USA. Octanol/water partition coefficients are described in more detail in U.S. Pat. No. 5,578,563.
  • Perfume components with a ClogP above 3 comprise: Iso E super, citronellol, Ethyl cinnamate, Bangalol, 2,4,6-Trimethylbenzaldehyde, Hexyl cinnamic aldehyde, 2,6-Dimethyl-2-heptanol, Diisobutylcarbinol, Ethyl salicylate, Phenethyl isobutyrate, Ethyl hexyl ketone, Propyl amyl ketone, Dibutyl ketone, Heptyl methyl ketone, 4,5-Dihydrotoluene, Caprylic aldehyde, Citral, Geranial, Isopropyl benzoate, Cyclohexanepropionic acid, Campholene aldehyde, Caprylic acid, Caprylic alcohol, Cuminaldehyde, 1 -Ethyl-4-nitrobenzene, Heptyl formate,

  • the composition is preferably for use in the rinse cycle of a home textile laundering operation, where, it may be added directly in an undiluted state to a washing machine, e.g. through a dispenser drawer or, for a top-loading washing machine, directly into the drum. Alternatively, it can be diluted prior to use.
  • the compositions may also be used in a domestic hand-washing laundry operation. It is also possible for the compositions of the present invention to be used in industrial laundry operations, e.g. as a finishing agent for softening new clothes prior to sale to consumers.
  • Preparation Compositions used in the invention can be prepared by any method suitable for preparing dispersed, emulsified systems.
  • One method involves the forming of a molten premixture of the active materials in water at an elevated temperature, adding additional water to obtain the desired active concentration, and then cooling to ambient temperature. When desired, some minor ingredients such as electrolytes, colouring agents, etc. may be post-dosed.
  • a second method involves the forming of the product by phase inversion of a water in hydrocarbon emulsion, wherein the cationic material is either part of the hydrocarbon phase or added as a separate predispersion. This method is advantageous, because this provides very finely divided hydrocarbon particles in the final product.

Participants were not asked to compare one set of garments to another.
  • a linear effects model was used to describe the three sources of variability. This model consists of a classical linear model (some function of the controlled and observed influences) and a random effects model. Only after fitting both is the error variance determined.
