Definitions

• ABSTRACT A neutralizing composition to effect the second stage of i I neutralization of a pennanent wave operation on the hair is an [30] Foreign Appucafion Dan aqueous solution containing an N-methylol compound as an July 25, 1968 Luxembourg ..56,584 active compound in amounts of 05-12 percent by weight of July 9, 1969 Luxembourg ..59,672 the composition.
• An oxidizing agent can also be included in the composition in amounts such that the concentration of ac- 424/71 tive compound and oxidizing agent is less than 1.7 moles/liter.
• the oxidizing solutions used for the fixation most often contain oxygenated water, although it is possible to use other conventional oxidizing agents for this operation.
• oxygenated water to effect the fixation phase of the permanent is accompanied by certain inconveniences in some cases.
• oxygenated water used at full strength is able to produce significant modifications in the keratin fibers which have already been degraded by the disulphide reduction.
• This inconvenience is particularly limiting in the case where one desires the effect of a permanent wave which is a variant of the permanent procedure. Accordingly, the hair rolled on the permanent hair rollers is dried most often under a hairdryer immediately after the fixation operation.
• the present invention provides a neutralizing composition to carry out the second phase of the permanent operation which includes a compound having the formula I:
• Y represents a radical -c, -c-,-c-
• the neutralizing composition according to the invention may also include an oxidizing agent utilized in a conventional manner for carrying out of the second phase of the permanent.
• an oxidizing agent utilized in a conventional manner for carrying out of the second phase of the permanent.
• the quantity of such oxidiz- Iing agent may be very notably less than the quantity of the :same oxidizing agent when used in conventional neutralizing solutions which do not include an N- methvlol compound according to the invention.
• the neutralizing lotions of the invention may effectively reduce the amount of oxygenated water employed to a concentration of about two volumes.
• composition which can be used to effect the neutralization of a permanent or a permanent wave set, the composition being characterized by the fact that it contains at least one compound of formula I, particularly one in which Y represents the group and at least one oxidizing compound which is introduced for the purpose of reacting with the compound of formula I so as to give a substantial temperature increase to the composition.
• oxidizing compounds which may be utilized in the composition according to the invention include, for example, oxygenated water, persalts or peroxides such as urea peroxide or the perborate of sodium or ammonium persulfate, sodium percarbonate or salts such as sodium bromate or potassium chlorate.
• the quantity of oxidizing compounds which is added at the time the composition according to the invention is used to effect the desired temperature rise is such that the moles of the formula] compound wherein Y represents is between 0.1 and 10 times the number of oxygen molecules added to the composition. It is essential that the mount of oxidizing agent introduced into the composition according to the invention be sufficient to effect an elevation in temperature.
• the concentration of the compound of formula I and the oxidizing compound less than 1.7 molecules per liter.
• the quantity of heat released can be regulated by taking into account the conversion of the number of reducing molecules to the number of oxidizing molecules.
• the pH of the fixing composition generally is between 1.5 and 6. Nevertheless, where the composition contains dimethylol ethylene thiourea, the pH may be between 8.5 and 10.
• the fixing composition may be an aqueous solution equally containing another solvent such as butyl-glycol, diethyleneglycol, glycerine, ethyl alcohol. Particularly interesting results are obtained when a mixture containing 25 percent water and 75 percent alcohol is used.
• compositions according to the invention are made up in two separate parts to be mixed at the moment of use, the first part containing the compounds of formula I and the second part containing the oxidizing compound.
• the first part can be made up of the compounds of formula I in the form of powder while the second part can be made up of a hydroalcoholic solution of the oxidizing compound.
• the compounds according to the present invention may also contain polymers for hair setting and particularly cationic polymers.
• the present invention also provides a new procedure to effeet the second stage of a permanent operation or permanent wave set, characterized by soaking the hair after it has been set with the help of a composition such as described above.
• the neutralizing composition is applied to the hair which has been previously set on rollers after which the hair is dried on the rollers with help of heat, for example, by means of a hairdryer.
• This method presents important advantages over the permanent setting technique previously used. First of all, it is not necessary to rinse the neutralizing mixture before drying the hair.
• the methylol compounds present in the mixture are capable of polymerizing with or in the keratinic fibers which as a result strengthens the fibers and augments the hold of the set.
• the neutralizing composition is applied on the hair before it is set on the rollers, then it is dried with heat under a hairdryer.
• This method presents the advantage of being more simple, since it is easier to impregnate the hair with the fixing lotion before the hair is rolled on the rollers.
• Another important method contemplated by the present invention for effecting the second stage of the neutralization of the hair permanent wave operation is characterized by impregnating previously reduced hair with a mixture including at least one compound of the formula I in which Y represents to which there is added at the time of use an oxidizing compound which reacts with the compound of formula I in which Y represents to give a notable rise in temperature of the mixture with the advantages indicated above.
• neutralization of the permanent wave set may be carried out in an equally effective manner by applying first the mixture having the compound of formula I in which Y represents and then applying immediately after a mixture having an oxidizing agent.
• the mixture was left on the hair, free of hair covering for 15 minutes.
• the hair was then rinsed and the following neutralizing lotion was then applied:
• the technique of setting described in this example has the advantage over the others of being easier since the hair is not rolled on the rollers until after it has been soaked with the neutralizing solution.
• dimethylolethylene urea 5 g silicone oil (blun) 0.3 g peptisant 0.5 g perfume 0.1 g acetic acid g.s.p. pH l.5
• EXAMPLE 5 The hair is shampooed and then rolled on the rollers. Each roller is then saturated with a reducing composition of the following formula:
• ammonium thioglycolate 9.5 g ammonium bicarbonate 12 g perfume 0.2 g water q.s.p. 100 cc
• This mixture is left on the hair (under a plastic hair covering) for 15 minutes.
• the hair is rinsed and then a neutralizing composition is applied that has been prepared at the moment of use by dissolving l g of dimethylol ethylene thiourea or a solution containing:
• cetyl-trimethyl-ammonium bromide 0.3 g
• the reducing solution used for the first phase of the permanent is as follows:
• ammonium thioglycolate 9 g mono-ethanolamine q.s.p. pH 9.5 perfume 0.3 g water q.s.p. I00 cc This solution is left in contact with the hair rolled on the adequate rollers for 15 minutes. After rinsing, a neutralizing composition is applied to the rollers, this solution being prepared at the moment of use by mixing a powder containing:
• cetyl trimethylammonium bromide 0.7 g formic acid 1 water q.s.p.
• EXAMPLE 7 A permanent for hair dyed with the help of an oxidizing agent coloring follows the conventional treatment.
