Definitions

  • This invention relates to the field of antiperspirant compositions and to methods of reducing perspiration.
  • this invention is concerned with reducing perspiration on the surface of the human body by the use of water-soluble or water-dispersible thiomers .
  • thiol groups of the thiomer enable or enhance the polymer's ability to act as a mucoadhesive and that this ability enables or enhances the antiperspirant activity of the thiomer.
  • mucoadhesives are materials that can attach to mucin in a biological surface. It is believed that the antiperspirant activity results, at least in part, from the ability of the thiomers to act as pore blockers. The thiomers, when swollen by water, are believed to serve to as plugs that may, at least in part, block the exit of sweat from eccrine sweat glands.
  • thiol groups of the thiomer may be by any of the means known in the art; co-polymerisation with a source of a thiol group is one such means. This may be done by free radical co-polymerisation.
  • the non-thiolated monomers may include acrylates and methacrylate (including the acids themselves), vinylbenzoic acid, and acrylamide.
  • the source of the thiol groups may be N,N' - bisacryloylcystamine, the disuphide bonds later being broken to give free thiol groups, or an N,N-dialkyldithiocabamate (e.g. vinylbenzyl-N,N-diethyldithiocarbamate, the thiocarbamate later being hydrolysed to release the free thiol groups .
  • Thiomers that are thiolation products of a pre- formed base polymer comprising carboxylic acid groups or amine groups are preferred, in particular thiomers that are cysteine derivatives of such polymers.
  • thiomers of this type are thiolation products (in particular cysteine derivatives) of the following pre-formed base polymers: i) Polymers of acrylic acid; ii) Polymers of methacrylic acid; iii) Polymers of maleic acid; iv) Polymers of itaconic acid; v) Carboxylated polysaccharides (e.g.
  • R represents the remainder of the polymer and n is from 2 to 5, preferably from 3 to 4 , and most preferably 3.
  • the extent of conversion is such that preferably from 1 to 50%, more preferably from 5 to 50%, and most preferably from 25-50% of the primary amine groups are converted.
  • carrier substance will depend upon the product form and properties desired. It is preferred that the carrier substance comprises less 20% by weight of water and it is more preferred that the carrier substance is anhydrous, as previously defined.
  • a suitable structurant may be a wax.
  • suitable waxes include beeswax, candelilla wax, carnauba wax, and other waxes having similar properties.
  • Such other waxes include hydrocarbon waxes, e.g. paraffin wax, mineral wax and microcrystalline wax; synthetic waxes, such as polyethylene of 2000 to 10000 daltons; waxy derivatives or waxy components of natural waxes, such as ester components, either extracted or synthesised, solid ester derivatives of glycerol or glycol, typically with linear saturated fatty acids, usually containing a significant fraction of C16-22 acid residues, which may be synthesised or obtained by hydrogenating the corresponding natural oil; petroleum waxes, waxy silicone polymers containing alkyl substituents of at least Ci 0 chain length; and waxy fatty alcohols, that normally are linear and often contain from 14 to 24 carbons, such as stearyl alcohol, cetyl alcohol and/or behenyl alcohol .
  • liquefied hydrocarbon gases and especially C 3 to C 6 hydrocarbons, including propane, isopropane, butane, isobutane, pentane and isopentane and mixtures of two or more thereof.
  • Preferred propellants are isobutane, isobutane/isopropane, isobutane/propane and mixtures of isopropane, isobutane and butane.
  • dimethylether may be employed as a volatile propellant .
  • a liquid carrier substance In liquid products, it is required to incorporate a liquid carrier substance.
  • a preferred product type is a particulate dispersion of the thiomer in the liquid carrier substance.
  • the liquid carrier substance may be selected from the liquid materials described as sensory modifiers and described hereinafter.
  • a preferred liquid carrier substance is a volatile silicone, because such a liquid can give a drier feel to the applied film after the composition is applied to skin.
  • the carrier substance may contain from 0.1 to 50% and particularly from 10 to 40% by weight volatile silicone. To class as "volatile" such material should have a measurable vapour pressure at 20 or 25°C. Typically the vapour pressure of a volatile silicone lies in a range from 1 or 10 Pa to 2 kPa at 25°C.
  • a volatile silicone may also be included in a stick, soft solid, or aerosol product.
  • Emollients, humectants, volatile oils and non-volatile oils are all suitable classes of sensory modifiers.
  • Chelators having an iron (III) binding constant of 10 26 or greater are preferred, with chelators having an iron (III) binding constant of 10 28 or greater being particularly preferred.
  • Especially preferred iron (III) chelators are N, N' -ethylenebis [2- (2- hydroxyphenyl) glycine] (EDDHA), triethylenetetraaminehexaacetic acid (TTHA) , and diethylenetriaminepentaacetic acid (DTPA) .
  • Iron (III) chelators are, in general, acids. They may be used as such in the compositions of the invention, although in compositions having an anhydrous continuous phase they are preferably used as a salt or acid salt of a protonated or quaternised amine.
  • Preferred amines for neutralisation of the chelator are 2 -amino-2 -methyl - 1 -propanol , diisopropanolamine, and 2-aminobutan-l-ol , cyclohexylamine .
