Title: Gelatinous preparations containing quaternary ammonium salt derivatives
IPC: A61Q19/00
Filed: 1964-04-21
Abstract: Gelatinous cleansing compositions contain as the gelling-agent a salt of a basic compound with an acid quaternary ammonium compound <FORM:1029043/C4-C5/1> wherein R is an unsubstituted C13-17 aliphatic hydrocarbon radical, R1 and R11 are methyl or ethyl, X is Cl or Br, and n is 2 or 3.  The salts have by themselves a washing and lathering effect.  The basic compound may be an alkali metal hydroxide, ammonia, an alkanolamine or a tertiary amine <FORM:1029043/C4-C5/2> wherein R, R1 and R11 are as above.  A preferre basic compound is N,N1-dimethylaminopropyl C14-18 fatty acid amide.  The acid quaternary ammonium compound may be a N,N1-dimethylaminopropyl C14-18 fatty acid amide quaternated with chlor- or brom-acetic acids.  The examples describe a shampoo, containing, besides the gelling agent, cetyl dimethyl (2-hydroxyethyl)-ammonium chloride, of pH 7.0 in gel form, optionally perfurmed, and a washing preparation, preferably for the hands, in gel form of pH 7.7, optionally perfumed, and containing, besides the gelling agent, the sodium salt of 2-caprinyl-imidazolinium-3-ethoxy-3-acetate.ALSO:Gelatinous cosmetic, hair setting, and pharmaceutical e.g bactericidal or disinfectant compositions contain as the gelling agent a salt of a basic compound with an acid quarternary ammonium compound <FORM:1029043/A5-A6/1> wherein R is an unsubstituted C13-17 aliphatic hydrocarbon radical, R1 and R11 are methyl or ethyl, X is Cl or Br, and n is 2 or 3.  The basic compound may be an alkali metal hydroxide, ammonia, an alkanolamine or a tertiary amine <FORM:1029043/A5-A6/2> wherein R, R1 and R11 are as above.  A preferred basic compound is N,N1-dimethylaminopropyl-C14-18 fatty acid amide.  The acid quaternary ammonium compound may be a N,N1-dimethylamino propyl C14-18 fatty acid amide quaternated with chloracetic or bromacetic acid.  The gelatinous pharmaceutical compositions may contain salicylic acid, boric acid, vitamins, local anaesthetics, hormones e.g. dexamethasone trimethyl acetate and are generally applied topically.  Salve bases containing the active gelling agent and (a) polyethylene glycol and (b) the condensation product of tetrahydroabietyl alcohol and ethylene oxide are exemplified.ALSO:Gelatinous hair dyeing and oxidant compositions contain as the gelling agent a salt of a basic compound with an acid quarternary ammonium compound <FORM:1029043/D1-D2/1> wherein R is an unsubstituted C13-17 aliphatic hydrocarbon radical, R1 and R11 are methyl or ethyl, X is Cl or Br, and n is 2 or 3.  The basic compound may be an alkali metal hydroxide, ammonia, an alkalolamine or a tertiary amine <FORM:1029043/D1-D2/2> wherein R, R1, and R11 are as above.  A preferred basic compound is N, N1-dimethylaminopropyl C14-18 fatty acid amide.  The acid quarternary ammonium compound may be a N, N1-dimethylaminopropyl C14-18 fatty acid amide quarternated with chlor-or brom-acetic acids.  The examples describe (a) an oxidant for hair in gel form comprising 100% H2O2, adjusted to pH 5.2 with tactic acid, and optionally perfumed; (b) hair dyeing gels containing <FORM:1029043/D1-D2/3>
