Definitions

• This invention relates to hair preparations containing rennet and particularly to lotions containing rennet for the control of dandruff.
• trypsin should be added to dental preparations in order to dissolve protein-containing food residues.
• Proteolytic enzymes such as keratinase have also been suggested for use as depilatories.
• Tryptic enzymes such as pancreatin
• hair preparations which are generally acidic
• lipases mixtures of proteolytic enzymes
• the present invention provides a hair preparation having activity against dandruff comprising, as an antidandruff agent from about 0.02 to about 1 percent by weight of rennet.
• hair lotions containing rennet are effective in controlling dandruff.
• Rennet is a substance normally used in cheese-making (and which is therefore commercially available) which contains the enzyme chymosin. It is usually prepared microbiologically; or alternatively it can be isolated from natural sources such as calves stomachs.
• the'amount of rennet required to give an acceptable antidandruff effect in the composition of the invention is from 0.0l to 1 percent, preferably 0.01 to 0.5 percent by weight.
• the most suitable form of hair preparation according to the invention is a lotion, that is an aqueous, alcoholic or aqueous/alcoholic solution or emulsion containing rennet, although'other forms, for example shampoos, gels and creams are not excluded.
• the pH of the preparation will be from 2 to 9, most preferably from 4.5 to 7.
• a particularly preferred mode of obtaining a composition within the pH range is to formulate it to include a buffer so that it is buffered at from about pH 5-6. r
• EXAMPLE 1 This is an example of an alcoholic hair lotion by weight Rennet l :220,000) 0.05
• Water balance EXAMPLEZ This is an example of an aqueous hair lotion I: by weight Rennet l:220,000) 0.05 Sodium benzoate 0. l 5 Perfume 0.2
• Water balance EXAMPLE 3 This is an example of an aqueous/alcoholic hair setting preparation by weight Luviskol VA64 2.0 Rennet l:l00,000) 0.1 lsopropanol 45.0 Perfume 0.4
• Water balance Luviskol VA64 (Trade Mark) is a commercially available polyvinylpyrrolidone/vinyl acetate copolymer.
• EXAMPLE 4 This is an example of a hair preparation in the form of a gel
• Carbopol 940 (Trade Mark) is a carboxyvinyl polymer which functions as a thickening agent.
• EXAMPLE 5 This is an example of a hair cream preparation by weight Paraffin Oil 1 Lanolin Glycerine Cityl alcohol Lanette N Rennet (l:l00,00) p-l-lydroxybenzoic acid-ethyl ester Perfume Water balance Lanette N (Trade Mark) is a 9:1 mixture of cetyl stearyl alcohol/sodium cetyl stearyl sulphate.
• EXAMPLE 6 This is an example of a hair preparation in the form of a conditioner by weight Katioran (Trade Mark) is a hydrophilic fatty acid condensation product.
• EXAMPLE 7 This is an example of a hair preparation in the form of a shampoo by weight Sodium alkyl polyglycol ether sulphate l5.2 Ethylene glycol distearate l.0 Sodium chloride 2.0 Technical grade rennet powder 0.5 Perfume 0.5 Water balance The composition was adjusted to pH 5.5 with citric acid.
• EXAMPLE 8 This is an example of a hair preparation in the form of a cream lotion k by weight Stearyl alcohol 3.5 Stearyl alcohol polyglycol ether 3.5spermaceti 5.0 lsopropyl myristate 3.0 Glycerine 5.0 Technical grade rennet powder 0.1 Perfume 0.4 Water balance This composition was emulsified and found to have a pH of 6.4.
• EXAMPLE 9 The following experiment was performed to ascertain the effectiveness of a lotion of the formulation shown in Example 1 in combatting dandruff.
• a group of 100 people with bad or moderate dandruff were asked to apply the lotion twice a day and to wash their hair at the beginning of the trial period but not during it.
• a second group of 100 were asked to apply a lotion of the following formula in the same way:
• a hair preparation having activity against dandruff comprising, as an anti-dandruff agent from about 0.0] to about 1 percent by weight of rennet.
• a hair preparation according to claim 1 in the form of a lotion in the form of a lotion.
• a hair preparation according to claim 1 in the form of a shampoo in the form of a shampoo.
• a hair preparation according to claim 1 having a pH of from about 2 to about 9.
• a hair preparation according to claim 5 having a pH of from about 4.5 to about 7.
• a hair preparation according to claim 6 having a pH buffered at from about 5 to about 6.
