Definitions

  • the present invention relates to a process for imparting optimal fragrance perception to damp and dry fabric. More particularly, the invention relates to a process for conditioning and fragrancing a substrate by providing a fragrance delivery vehicle containing a water insoluble oil, a conditioner containing a cationic active, and a fragrance composition specifically designed for the delivery vehicle. A substrate is then contacted with the fragrance delivery vehicle in an aqueous solution. Compositions are also provided for conditioning and fragrancing a substrate.
  • Liquid conditioning products for treating substrates contain cationic materials as a key active ingredient.
  • Other ingredients such as oils as described in WO 97/44424, may be used in liquid conditioning products together with a cationic active to aid in the deposition of fabric treatment agents. (See also WO98/16538, which is incorporated by reference as if recited in full herein.).
  • oils as part of the conditioner, may be delivered during the final rinse.
  • Escher uses hydrophobicity, determined as the partition coefficient of the chemical between octanol and water and expressed as log P. Similar to Muller' s disclosure that the higher the log P value, the greater the substantivity. Log P may be measured directly but more conveniently it may be calculated from the structure of the molecule, using one of several commercially available software programs, such as ACD Software, ACD/logP calculator version 4.0, Advanced Chemistry Development, Toronto, Ontario Canada. The calculated value is abbreviated to CLogP.
  • the vapor pressure of an aroma chemical which is related to its boiling point, is also included to ensure that it does not evaporate during the rinse cycle to which the conditioner is added, and that it survives the drying process ensuring that sufficient aroma chemical is present to provide a lasting scent on the dry substrate.
  • High boiling point aroma chemicals will evaporate more slowly giving a longer lasting fragrance perception.
  • Vapor pressure and boiling point may be measured or calculated using one of the commercially available software programs, such as ACD Software ACD/Boiling Point calculator version 4.0.
  • Another way to impart good fragrance to a substrate is to have the substantive part of the fragrance composed of an aroma chemical with low perception thresholds.
  • a variety of techniques are available to determine the perception threshold. See e.g., Neuener-Jehle and Etzweiler in Art Science and Technology, editors Lampaski and Muller, ch.6, 153-212 (1991).
  • a fragrance must be composed of at least 70% aroma chemicals with a CLogP > 3.0 and a boiling point of >250°C at 760 mm Hg.

  • the active agents disclosed as conditioners by these patents are predominantly cationic, having at least one of the alkyl chains with a chain length at least equal to 12, preferably greater than 16.

  • optimum fragrancing of both damp and dry substrates has been difficult to achieve using the methods summarized above, which rely solely on water insolubility, boiling point, and perception threshold.
  • a water insoluble oil when combined with a cationic active, provides excellent fragrance deposition and perception on both damp and dry substrates, such as fabrics or hair, so long as the fragrance composition is constructed according to the present invention.
  • an oil in, e.g. a fragrance delivery vehicle enliances the deposition of a substantive aroma chemical, i.e. one that has a CLogP higher than 3.0.

  • Another embodiment of the invention is a process for conditioning and fragrancing a substrate.
  • This process includes providing a fragrance delivery vehicle containing a conditioner having a cationic active, a water insoluble oil, and at least 0.1%(wt) of a fragrance composition.
