Patent ID: 8470833

Claim:
A hair growth and/or regrowth composition comprising; a. at least one compound selected from the group consisting of compounds represented by the formulae: and mixtures thereof, wherein R 1 is a moiety selected from the group consisting of moieties of the formula—N(R 3 )(R 4 ), wherein R 3 and R 4 are selected from the group consisting of hydrogen, lower alkyl, lower alkenyl, lower aralkyl, and lower cycloalkyl, and taken together R 3 and R 4 may be a heterocyclic moiety selected from the group consisting of aziridinyl, azetidinyl, pyrrolidinyl, piperidino, hexahydroazepinyl, heptamethylenimino, octamethylenimino, morpholino, and 4-lower-alkylpiperazinyl, each of said heterocyclic moieties having attached as substituents on the carbon atoms 0 to 3 lower alkyl groups, hydroxy or alkoxy; and wherein R 2 is selected from the group consisting of hydrogen, lower alkyl, lower alkenyl, lower alkoxyalkyl, lower cycloalkyl, lower aryl, lower aralkyl, lower alkaryl, lower alkaralkyl, lower alkoxyaralkyl, and lower haloaralkyl and the pharmacologically acceptable acid addition salts thereof; and b. from about 1% to about 5% of a lactic acid or lactate selected from the group consisting of lactic acid, salts of lactic acid, prodrugs of lactic acid, and mixtures thereof for solubilizing the compounds of formula I, formula II and mixtures thereof; c. from about 0.1% to about 99% by weight of an admixture, comprising: i. from about 0.01% to about 99.98% by weight of the admixture of an acid selected from the group consisting of pyruvic acid selected from the group consisting of pyruvic acid, lithium pyruvate, sodium pyruvate, potassium pyruvate, magnesium pyruvate, calcium pyruvate, zinc pyruvate, manganese pyruvate, methyl pyruvate, salts thereof, prodrugs thereof, and mixtures thereof; ii. from about 0.01% to about 99.98% by weight of the admixture of an antioxidant; and iii. from about 0.01% to about 99.98% by weight of the admixture of a fatty acid mixture or fatty acid mixture source comprising at least 7 unsaturated or saturated fatty acids selected from the group consisting of butyric acid, caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, myristoleic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, arachidic acid, gadoleic acid, pentadecanoic acid, margaric acid, margaroleic acid, behenic acid, dihomolinoleic acid, arachidonic acid and lignoceric acid wherein the composition accelerates the onset of the anagen phase of hair growth in mammals.
