Definitions

• This invention relates to hair preparations, and more particularly to hair control preparations for holding the hair in a desired configuration. Preparations of this .kind include hair setting lotions and hairsprays, the
• the resins which have the better hair retaining properties are those which. are relatively flexible whereas those which are the more easily combed or brushed out of the hair'are the more brittle resinsaln other words, those resins having the lower glass transition temperatures (Tg) have the better hold characteristics and those of higher glass transition temperatures have the better comb-out properties.
• improved hair control preparations can be formulated by including along with resin a resin-modifying agent which is normally solid (i.e.', is solid at 20 C) and which softens the resin and improves its initial holding properties but which over a relatively shortperiod of time, say within hours, volatilises from the hairwhereby the resin is gradually converted into a form in which it is more easily combed out of the hair.
• resin normally solid (i.e.', is solid at 20 C) and which softens the resin and improves its initial holding properties but which over a relatively shortperiod of time, say within hours, volatilises from the hairwhereby the resin is gradually converted into a form in which it is more easily combed out of the hair.
• the invention provides a hair control preparation comprising a solution of a film-forming resin and a normally solid material which plasticises the resin and which gradually volatilises from the resin after applying the preparation to the hair, the weight ratio of resin to volatile plasticiser being from 1:2 to :1.
• An advantage of the invention is that by the use of the volatile plasticiser one can improve the initial holding properties of the resin (matching that obtainable with acornparable or even greater amount of a softer resin) and produce a resin deposit which develops over a period of time an improved ease of removal as the plasticiser volatilises from the hair.
• the use of a volatile plasticiser in accordance with the invention permits one to improve the initial hold properties of a hair preparation without increasing the amount of the resin in the preparation: an increase in the amount of the resin would result in more resin being applied to the hair with the consequence that the hair would be more difficult to comb out.
• the film-forming resins used in preparations in accordance with the invention desirably have glass transition temperatures (Tg) of at least 20 C.
• Tg glass transition temperatures
• the use of the Tg is a common way of characterising resins and is described for example by Burrell, H in Official Digest, 34, 131 (1962). It can be determined by the technique known as Differential Thermal Analysis (see, for example, the method of Keavney, JJ and Eberlin, EC in J.Appl.Polymer Sci., 3 47 (1960).
• a high Tg is an indication of the brittleness of a resin.'ln accordance with our finding that the more brittle the resin the more easily it is combed out of the hair,the preferred resins used in hair compositions of this invention are those having a Tg of at least 35 C and usually no more than 150 C.
• Vapour Pressure estimated values It is to be understood that the invention is not limited solely to the resin/volatile plasticiser combinations specifically referred to above. Some experimentation may be necessary in order to select other suitable combinations of resin and normally solid volatile plasticiser for use in the present invention.
• a plasticiser for one resin is not necessarily suitable for plasticising another resin.
• benzophenone when used with resins obtained by copolymerising vinyl pyrrolidone with no more than an equal amount of vinyl acetate (and with certain other water-soluble resins) is reported in British Patent Specification No. 868,879 to result in a stiffening of the resin (i.e., the opposite of a plasticising effeet).
• the film-forming resin and the volatile plasticiser are both present in the hair preparation as a solution in a mutually suitable solvent.
• the solvent can be a volatile organic solvent such as an alcohol, especially ethanol, isopropanol or 2-methoxyethanol: methylene chloride is also a suitable volatile organic solvent.
• the weight ratio of film-forming resin to volatile plasticiser in the hair preparation according to the invention is from 1:2 to :1.
• the preferred weight ratio of film-forming resin to volatile plasticiser is from 1:1 to 10:1.
• the amount of resin present in the solution will depend on the degree of hold the product is intended to produce and will usually be from 1 to 10 percent by weight of the solution.
• the hair preparation is preferably in the form of an aerosol hairspray.
• the solvent especially one of those previously exemplified, the film-forming resin and the volatile plasticiser will be present in an aerosol dispenser together with a suitable aerosol propellant, usually a liquefied normally gaseous substance.
• a suitable aerosol propellant usually a liquefied normally gaseous substance.
• propellants are trichlorofluoromethane (propellant l 1) and dichlorodifluoromethane (propellant 12) but others may be employed.
• Suitable propellants and propellant mixtures 4 for use with hairsprays are well known tothose in the art.
• Aerosol hairspray preparations in accordance with the invention will comprise concentrate and propellant in the usual ratios, generally from about 2:1 to 1:5 with the concentrate having typically-the following composition:
• the preparation may simply be in the form of a solution of the resin and plasticiser in the solvent, for example in the weight proportions as set out for the above concentrate.
• an aqueous alcoholic solvent can be used.
• water it might also be possible to use water as the solvent, although the presence of a volatile organic solvent is preferred to give a quick drying product.
• Other conventional ingredients can be incorporated, if desired, for example a denaturant for ethanol.
• a process for treating human hair to impart hold to a desired style and subsequently to facilitate the brush out property of the hair as the hold diminishes by applying to the hair a hair control preparation of the type defined herein.

• the comb used was one which had a r strain gauge transducer cemented. onto the back of it and the varying resistance produced by varying strains on the gauge as the hair travelled through the comb was processed electronically.
