Definitions

  • This disclosure relates to a method of reducing malodour and to compositions for use therein.
  • malodour perception reduction composition for use in a method as hereinabove defined.
  • the proportions of Group A or Group B compounds stated hereinabove include only those compounds which are present to the extent of at least 0.1% by weight. It is of course possible and permissible to include quantities of Group A and Group B compounds below 0.1%, and while these may have some hedonic effect, they are not considered to contribute significantly to the malodour counteraction.
  • Standard perfumery ingredients any ingredient normally found in perfumes, including perfume molecules, and any necessary solvents and other commonly-used ancillary materials.
  • Perfume ingredients are well known to those skilled in the art, and include those mentioned, for example, in S. Arctander, “Perfume and Flavor Chemicals” (Montclair, N.J., 1969), in S. Arctander, “Perfume and Flavor Materials of Natural Origin” (Elizabeth, N. J., 1960) and in “Flavor and Fragrance Materials - 1991", Allured Publishing Co. Wheaton, 111. USA.
  • Perfume ingredients may include natural products such as extracts, essential oils, absolutes, resinoids, resins, concretes etc., and also synthetic substances such as hydrocarbons, alcohols, aldehydes, ketones, ethers, acids, esters, acetals, ketals, nitriles, etc., including saturated and unsaturated compounds, aliphatic, macrocyclic and heterocyclic compounds.
  • ingredients Although it is possible for such ingredients to be completely absent, in a particular embodiment, they will be present. More particularly, they are present in a proportion of from 5 - 10% by weight of the composition. This allows the skilled person suitable latitude to formulate the composition such that it can both perform its function and have a desirable fragrance.
  • At least 6% by weight of Group A materials is present.
  • compositions comprise at least 2 Group A materials plus at least 2 Group B ingredients, other particular compositions comprise at least 6 Group A plus 6 Group B ingredients with the proviso that at least 0.1% of a material must be present before it may be considered to contribute significantly towards the efficacy of the compositions, i.e. materials present at concentrations below 0.1% w/w are ignored in the calculation of the number and amount of Group A or Group B ingredients in the composition.
  • Oxacycloheptadecan-2-one (cyclohexadecanolide [Silvanone tm ]* );
  • Silvanone tm is a commercial blend of the compounds cyclopentadecanone and cyclohexadecanolide.
  • Group A compounds are selected from:
  • composition for use in the method comprises a combination of a compound A blend and a compound B blend, selected as follows from the abovementioned compounds: Compound A blend Compound B blend

  • a consumer product adapted for the cleaning and care of household substrates comprising a product base and a malodour perception reduction composition as hereinabove defined. It is especially effective in connection with fabric cleaning and care, and may be used in conjunction with any consumer product normally used such purposes, for example, washing detergents, fabric conditioners and fabric treatment products.
  • product base is meant all the known standard ingredients for any desired consumer product. These will vary widely, depending on the nature of the composition, but the skilled person will easily be able to provide any suitable product base. Typical examples of such standard ingredients include surfactants, fillers and extenders, abrasives, rheology modifiers, thickeners, gelling agents, and the like.

  • the amounts of the compounds used in consumer products will vary considerably, depending on the nature of the product and the effect desired. However, an appropriate quantity may be determined in every case by routine experimentation by the skilled person. As a general guide, the proportions of compound A in a consumer product will vary between 0.001 and 0.2%, more particularly between 0.01 and 0.1%, and those of compound B between 0.1 and 1%, more particularly between 0.2 and 0.6%, all being by weight of the total consumer product.

  • the sensory panel consists of a pool of between 25 and 35 members, who are all screened and then trained over a period of 6 months. Training includes learning to identify individual odour characters in complex mixtures, and to score their perceived intensity using a ratio scoring technique (Magnitude Estimation). The level of efficiency of the panel is continuously monitored to ensure a high level of accuracy and reproducibility.
  • Each panel member assesses each sample for the intensity of malodour and MPPC that can be perceived in the headspace of the glass vessel using a line scale anchored at the extremes (0-100).
  • the malodour control is used as a standard (perceived intensity 75) against which all other perceived intensities are scaled.
  • perfume only controls detailed above hidden blanks (malodour but no MPPC) are included as further internal controls.
  • the scores for each of the panellists are normalised and averaged to give a consensus score across the whole panel.
  • Geovertol [5,8a-dimethyl-l,3,4,7,8,8a-hexahydronaphthalen-4a(2H)-ol] imparts a odour similar to a mould/mildew malodour and was used in testing as a 10% dilution in diethyl phthalate (DEP).
  • DEP diethyl phthalate
  • MPPC formulations 3.2, 3.3, 3.4, 3.5 and 3.6 detailed in Table 1 were made according to the description.

Abstract

L'invention porte sur un procédé qui permet de réduire la perception de mauvaise odeur des moisissures présentes sur un substrat domestique, tel qu'un tissu ou des surfaces dures. Le procédé de l'invention consiste à traiter le substrat avec une composition comprenant : (i) de 3 à 15% en poids d'au moins un composé du groupe A (tel que défini dans la description); (ii) de 25% à 97% en poids d'au moins un composé du groupe B (tel que défini dans la description); et (iii) jusqu'à 25% en poids d'ingrédients de parfumerie ordinaires.
