Definitions

  • the present invention relates to the field of softeners. More particularly, the invention concerns a compound derived from a 3-(dialkylamino)-l,2-propanediol and a non-linear fatty acid, as well as the use of said compound as anti-gelling or viscosity- control ingredient in softening articles.
  • Gelation of softening articles is a known problem which is notably enhanced, at low or high temperature, by a prolonged storage time and/or the presence of alcohols, in particular perfumery alcohols.
  • This gelation manifests itself macroscopically by an increase of the composition viscosity and a concomitant and irreversible thickening, or sometimes even by a solidification of the softener compositions.
  • the gelation is believed to be due to the surfactants present in composition, and possibly to the interactions of said surfactants with other ingredients.
  • all existing or commercial softener compositions contain surfactants which have a linear chain residue.
  • EP 280550 discloses the use of non-ionic surfactants, e.g. alkoxylated aliphatic alcohols, as a viscosity-control agent or an anti-gelling ingredient in softener compositions containing not more that 6% of a cationic fabric softener and a free fatty acid.
  • non-ionic surfactants e.g. alkoxylated aliphatic alcohols
  • WO 95/22594 teaches the use of a perfume which is associated with a carrier to avoid the gelation of bases containing ionic surfactants; however this solution is useful only when the gelation is due to the sole perfume.
  • WO 97/17419 proposes to use specific non-ionic di- or tri- esters.
  • the present invention relates to the use of a compound as anti-gelling or viscosity-control ingredient, i.e. capable of preventing or delaying the gelation of a softener composition.
  • Said compound is a nonlinear fatty acid derivative.
  • nonlinear fatty acid we mean here a fatty acid having at least a tertiary carbon atom in its hydrocarbon radical, or a fatty acid having up to six hydroxyl functions, said hydroxyl being possibly derivatized as ethers or esters bonded to its hydrocarbon radical.
  • a fatty acid having at least a tertiary carbon atom in its hydrocarbon radical we mean here a fatty acid containing a moiety which is cyclic, aromatic or branched.
  • Non-limiting examples of said non-linear fatty acid are of the formulae (a), (b) or (c) wherein the asterisk indicate one of the tertiary carbon atom:
  • Suitable compounds for the purpose of the invention e.g. for a use as anti-gelling ingredient in a softening articles, are of formula
  • n is 0.5 or 1 ;
  • A represents an anion of an acid such as a chloride, a bromide, a iodide, a CO 3 2" or HCO 3 " , a sulfate, a methyl or ethyl sulfate, a tosylate or a nitrate; and each R 1 represents, simultaneously or independently, a hydrogen or oxygen atom, a benzyl or Ci to C 6 alkyl group or a polyethylene- or polypropyleneglycol group, having from 1 to 5 monomer units; and each R 2 represents, simultaneously or independently, a C ⁇ o-C 3 o saturated or unsaturated hydrocarbon radical having at least a tertiary carbon atom, or a C ⁇ o-C 30 saturated or unsaturated hydrocarbon radical having from one to six -OCOR or -OR groups bonded to its hydrocarbon chain; R 3 being an hydrogen atom, or a C ⁇ -C 22 saturated or unsaturated hydrocarbon group
  • the compounds of formula (I) are those wherein n is 0.5 or 1;
  • the compounds of the invention may be obtainable by the reaction of one molar equivalent of an appropriate al andiol amine of formula
  • source of the fatty acid R 2 COOH (R 2 being defined as in formula (I)), or of the corresponding triglyceride
  • R 2 being defined as in formula (I)
  • a natural oil or a product obtained by a transformation of a natural oil examples of such oils are isostearic acids, hydroxystearic acid, ricinoleic acid or polyterpenic acids such as farnesic acid.
  • one of the objects of the present invention is the use as anti-gelling or viscosity-control ingredient of a compound of formula (I).
  • said use consists of a method to prevent or delay the gelation of a softening article, which method comprises adding to said article an effective amount of at least one compound of formula (I).
  • use of a compound of formula (I) it has to be understood here also the use of the compound (I) in any of its forms which can be advantageously employed as anti-gelling ingredient.
  • Said forms are also an object of the present invention. hi an embodiment of the invention, one of said forms is a composition of matter consisting of at least one compound of formula (I) and a perfume base.
  • one of the elements which may be at the origin of the gelling phenomenon is admixed with the anti-gel ingredient, and therefore said two ingredients will be added at the same time into the softener base, minimizing thus any risk of formation of gel into the softening article.
  • perfume base we mean here a composition comprising at least one perfuming compound and possibly one or more solvents or adjuvants commonly used in the perfume industry.
  • perfuming compound it is meant here a compound, which is of current use in the perfume industry, i.e. a compound which is used as ingredient in perfuming preparation or composition in order to impart an hedonic effect.
  • such a compound, to be considered as being a perfuming one must be recognized by a person skilled in the art as being able to impart or modify in a positive or pleasant way the odor of a composition, and not just as having an odor. Its is therefore understood here that any mixture resulting directly from a chemical synthesis in which the compound of the invention is involved as a starting intermediate or as an end-product is not a composition of matter according to the invention.
  • these perfuming co-ingredients belong to chemical classes as varied as alcohols, aldehydes, ketones, esters, ethers, acetates, nitriles, terpene hydrocarbons, nitrogenous or sulphurous heterocyclic compounds and essential oils of natural or synthetic origin. Many of these co-ingredients are in any case listed in reference texts such as the book by S.
  • perfume bases which contain alcohols or aldehydes, as perfuming compounds, are particularly interesting.
  • solvents and adjuvants commonly used in perfume bases cannot be exhaustive. A skilled person in the art is able to select them on the basis of the nature of the product to be perfumed.
  • solvents commonly used in perfumery bases one can cite compounds such as dipropyleneglycol, diethyl phthalate, isopropyl myristate, benzyl benzoate, 2-(2-ethoxyethoxy)-l-ethanol or ethyl citrate, which are the most commonly used.
  • another object of the present invention is a softening article comprising: a) a compound of formula (I), as defined above, or a composition of matter, as defined above, and b) a softening base.
  • a perfumed product according to the invention comprises at least a part of the whole formulation corresponding to an unperfumed softener, e.g. one or more suitable surfactant, an anti-gel effective amount of at least an invention's compound and possibly an olfactive effective amount of a perfume base as defined above.
  • an unperfumed softener e.g. one or more suitable surfactant, an anti-gel effective amount of at least an invention's compound and possibly an olfactive effective amount of a perfume base as defined above.
  • Suitable softening bases comprise fabric softeners, shampoos, hair conditioners and other hair care products or yet skin emollients or cosmetic products.
  • the fabric softeners being the preferred bases.
  • the softening base advantageously contains at least a surfactant obtainable by the reaction of one to three molar equivalents of a C10-C20 fatty acid with one molar equivalent of an amino alcohol of formula
  • a and n are as defined in formula (I), d is 1 or 2, R represents a hydrogen atom or a R 1 group as defined formula (I), m is 2 or 3 and (m+s) - 4.
  • the proportions in which the compounds according to the invention can be incorporated into the various aforementioned compositions or articles vary within a wide range of values. These values are dependent on the nature of the composition or product as well as the nature of the co-ingredients in a given composition.
  • concentrations of the compound of formula (I) in one of the aforementioned product are in the order of 0.01% to 10% by weight, percentage being based on the weight of the article into which they are incorporated. Concentrations higher than these, such as in the order of 2% to 80% by weight, can be used when these compounds are incorporated into compositions.
