Definitions

  • This invention relates to hairsprays, sometimes called hair lacquers.
  • Hairsprays are products containing a film-forming resin which when applied to the hair help to hold the hair in place.
  • the film-forming resin can be sprayed onto the hair utilising different types of dispenser.
  • Most hairspray products utilise an aerosol container, from which the hairspray composition is discharged by a propellant, but becoming more common as dispensers at the present time are pump spray applicators, which utilise a mechanical pump for the discharge of the composition comprising the film-forming resin.
  • Hairspray compositions can also be applied to the hair from a so-called squeeze pack, the pressure generated by squeezing the pack being utilised for the discharge of the composition through the spray orifice.
  • the composition sprayed onto the hair comprises a solution of the hairspray resin in a suitable solvent, usually an alcoholic or aqueous alcoholic solvent.
  • This invention is concerned with improving the holding power of a hairspray.
  • a hairspray product consisting of a hairspray composition within a container for spraying the composition onto the hair, wherein the hairspray composition comprises 0.4 to 7.5% by weight of the composition of a hairspray resin which is not a drag reducing agent having a drag reduction efficiency of at least 2%, and a solvent for the hairspray resin, the composition also comprising a drag reducing agent having a drag reduction efficiency of at least 2% dissolved in the solvent whereby the holding power of the hairspray composition is improved, the weight ratio of the hairspray resin to the drag reducing agent being 10,000 to 2:1 and the amount of the drag reducing agent being less than 0.3% by weight of the hairspray composition.
  • the holding power of the applied hairspray resin can be very considerably enhanced and to a degree far exceeding any benefit that could be predicted. Indeed, the amounts of added drag reducing agent which are effective to improve the holding power of a hairspray, as demonstrated hereinafter, are so small that no measurable improvement at all in hold would have been expected.
  • a polymeric material is tested for its drag reduction potential by determining its effect on the flow rate of a solvent for the hairspray resin (in which it is required to be soluble) by feeding a solution of the material, in a concentration specified below, at room temperature (about 20°C) and pressure of 15 psig (1 kg cm- 2 gauge) to a capillary tube of length 32 cms and capillary diameter 1.5 mm.
  • the drag reduction efficiency of the material expressed as a percentage, is given by the expression where f solvent is the discharge rate of the solvent and f solution is the discharge rate of the solution of the polymer in the solvent.
  • Drag reduction efficiencies referred to herein are determined using solutions of concentration 0.01% or 0.10% w/w.
  • a material is to be understood herein as having a drag reduction efficiency of at least 2% if its drag reduction efficiency at a solution concentration of 0.01% and/or 0.10% w/w is at least 2%.
  • drag reduction efficiency is substantially independent of the nature of the hairspray solvent. Consequently, it is usually convenient to test materials for their drag reducing efficiency in either water or, if not soluble therein, in methylene chloride.
  • a material has a drag reduction efficiency of at least 2% in one of these solvents it will be readily possible to formulate a solvent system for a hairspray resin and the drag reducing agent based on one or more of the conventional hairspray solvents, particularly lower aliphatic alcohols, methylene chloride and mixtures thereof with or without water.
  • drag reducing agents which have a drag reduction efficiency of at least 10%.
  • a particularly effective group of materials for enhancing the holding power of hairspray resins are certain polyoxyethylenes. These non-ionic polymeric materials are soluble in water and mixtures of water and organic hairspray solvents and are effective in enhancing the holding power of a hairspray at very low levels, particularly in the case of those polyoxyethylenes having an average molecular weight exceeding one million which are effective even at levels of less than 50 parts per million of the hairspray composition.
  • Water soluble polymers of ethylene oxide are commercially available from Union Carbide Corporation under the trade name POLYOX Water Soluble Resins (POLYOX is a trade mark).
  • Typical values for the drag reduction efficiency of these polyoxyethylene resins are given below.
  • Water is a suitable solvent for the determination of drag reduction efficiency.
  • the polyoxyethylene designated Polyox 10 (average molecular weight about 1 x 10 5 ) is not a drag reducing agent. At both 0.01% and 0.10% concentrations in water it was not shown to exhibit any drag reducing properties. With regard to the obtaining of negative values for the drag reduction efficiency in certain cases as indicated above, it should be explained that these polymers tend to increase the viscosity of solvents and this will of course tend to reduce the rate of flow of the solvent through the capillary tube. The consequence is that above a certain level of addition, depending on the molecular weight of the polyoxyethylene, the net effect of the additive is to reduce the rate of flow of the solvent. However, this effect appears to be of no significant as far as the present invention is concerned. It is only important that the polymer should have a drag reduction efficiency of at least 2% as determined above.
  • An especially useful group of hair hold enhancing agents are certain hydroxypropylcellulose polymers which are soluble in the polar organic solvents, e.g. lower aliphatic alcohols, usually used as solvents for hairspray resins. These non-ionic polymers, which are also soluble in water, are therefore particularly useful additives for a wide range of hairspray products in order to improve holding power.
  • Hydroxypropylcelluloses are commercially available from Hercules Incorporated under the trade name KLUCEL These hydroxypropylcelluloses have a degree of substitution (MS) within the range 2.5 to 10, the MS being the average number of hydroxypropyl groups per anhydroglucose unit.
  • Typical values for the drag reduction efficiency of these hydroxypropyl celluloses are given below. Water is a convenient solvent for the determination of drag reduction efficiency.
  • polyacrylic elastomers for example the poly(ethyl acrylate) elastomer commercially available from the B. F. Goodrich Chemical Company under the trade name "Hycar 4021-45".
  • This non ionic material consists essentially of polymerised ethyl acrylate although it comprises 1 to 5% of a compound providing reactive cure-sites, and believed to be 2-chloroethyl vinyl ether, since the polymer is intended for use as a vulcanisable rubber.
  • Poly(ethyl acrylate) is not soluble in water or alcoholic solvents but is soluble in methylene chloride and therefore can be used in hairsprays containing methylene chloride as a solvent. It had a drag reduction efficiency of 12% at 0.01 % concentration and a drag reduction efficiency of 30% at 0.10% concentration.
  • a further type of polymer shown to be effective as a drag reducing agent is a very high molecular weight cationic cellulosic polymer having the structural formula: wherein Reel! represents the residue of an anhydroglucose unit, wherein each R individually represents a substituent group of the following general formula: where m is a whole number of from 0 to 10, n is a whole number of from 0 to 3, and p is a whole number of from 0 to 10, and Y is an integer such that the polymer has a viscosity of from 1,000 to 2,500 centipoises in a 1% aqueous solution at 25°C (Brookfield viscometer LVF, 30 rpm, spindle No. 3).
  • the average values per anhydroglucose unit are: n from 0.35 to 0.45 and the sum of m + p is from 1 to 2.
  • a suitable cationic cellulosic resin is that available commercially from the Union Carbide Corporation under the trade name "Polymer JR 30M". This polymer is less useful than the other drag-reducing agents referred to above as it requires the use of relatively large amounts of water to be present in the composition to act as solvent since it is not soluble in ethanol or methylene chloride. Lower viscosity grades of these cationic cellulosic polymers such as the grades available under the trade names Polymer JR 125 (viscosity at 25°C in 2% solution of 75-175 centipoises, Brookfield Spindle No.
  • Preferred drag reducing agents are those which are soluble in either ethanol or methylene chloride. It is also preferred to employ drag reducing agents that are solid at normal temperature (25°C).
  • hairspray resins have been used in commercially sold hairspray products. These include polyvinylpyrrolidone; copolymers of from 92.5 to 87.5% vinyl acetate and from 7.5 to 12.5% crotonic acid as described in US Patent No. 2,996,471, e.g.
  • amphoteric acrylic resins as described in US Patent No. 3,726,288, such as the acrylamide/acylate/butylamino-ethyl methacrylate terpolymer containing carboxy groups available commercially under the trade name Amphomer; and copolymers of methyl vinyl ether and maleic anhydride (molar ratio about 1:1) and such copolymers esterified with a saturated aliphatic alcohol containing from 1 to 4 carbon atoms, an example thereof being the resin available commercially under the trade name Gantrez ES425.
  • Suitable neutralising agents which may be included in the hairspray composition are amines, especially aminoalcohols, preferably 2-amino-2-methyl-1,3-propanediol and 2-amino-2-methyl-1-propanol.
  • Other suitable neutralising agents are also given in US Patent No. 2,996,471.
  • Carrier liquids or solvents for the hairspray resin which are commonly used in formulating hairspray compositions are ethanol, isopropanol, methylene chloride, 2-methoxyethanol and 2-ethoxyethanol, and mixtures thereof with water.
  • the carrier liquid may comprise more than one of these organic solvents. It is required, of course, that the carrier liquid for the resin should also be a solvent for the drag reducing agent.
  • the solvent will usually amount to from about 5% to about 99.5% by weight of the composition. In aerosol products the solvent will be from about 5% to about 95% by weight, usually from about 10% to about 90% by weight.
  • the composition within the container will also include a propellant such as a liquefied gas propellant or a compressed gas propellant.
  • a propellant such as a liquefied gas propellant or a compressed gas propellant.
  • liquefied gas propellants are the halogenated hydrocarbons and the liquefiable hydrocarbons.
  • Commonly used liquefied gas propellants are trichlorofluoromethane (propellant 11), dichlorodifluoromethane (propellant 12), butane and propane, and mixtures thereof.
  • Other suitable propellants are referred to in US Patents Nos.
  • Liquefied gas propellants are generally used in amounts within the range 10 to 90% by weight of the hairspray composition.
  • compressed gas propellants are carbon dioxide, nitrogen and nitrous oxide. These propellants are usually used in an amount of from about 1% to about 10% by weight of the total hairspray composition.
  • Liquefied gas propellant may or may not be miscible with the solvent for the hairspray resin and drag reducing agent.
  • the amount of the drag reducing agent which is incorporated in the hairspray composition to increase the holding power of the hairspray resin is relatively small.
  • the amount required will depend both on the molecular weight and on the chemical type of the drag reducing agent in so far as these affect drag reduction efficiency. Improvements in holding power have been obtained in certain cases with amounts of the drag reducing agent as small as 0.001 % by weight of the composition or even less.
  • amounts of the drag reducing agent as small as 0.001 % by weight of the composition or even less.
  • aerosol products somewhat higher amounts are desirable as the proportion of propellant in the composition is increased.
  • the more efficient the drag reducing agent the smaller the amount required to be incorporated in the hairspray composition to improve the holding power.
  • the use of the higher molecular weight members is preferred.
  • Drag reducing polymer can lead to the production of a spray with a very small cone angle, (or even to the production of a jet or stream rather than a spray) or to an unacceptably coarse spray where the droplets are too large.
  • the amount of the drag reducing agent should be less than 0.3% by weight of the hairspray composition. It is preferred that the drag reducing agent should not exceed 0.2% by weight of the composition.
  • suitable amounts of drag reducing agent can readily be determined by those skilled in the art.
  • the holding power of a hairspray product obviously also depends on the amount of the hairspray resin present in it. It is usual in conventional products to include at least about 1 % by weight of hairspray resin in order for the product to impart a satisfactory hold to the hair. Amounts in the range about 1 to 3% by weight are therefore quite normal in commercial products although if a product is required to have a higher than normal holding power the amount of resin can be correspondingly increased.
  • An important practical consequence of our discovery that the inclusion of a drag reducing agent in a hairspray product can improve the holding power of the product is that it enables one to substantially reduce the level of hairspray resin without loss of product efficacy.
  • the amount of the hairspray resin can be as little as about 0.4% by weight of the composition while still retaining good hold properties.
  • the upper limit of resin is not critical.
  • the amount of hairspray resin will generally be in the range 0.4 to 7.5%, more usually 0.4 to 5%, by weight of the composition.
  • a surprising feature of this present invention is that the drag reducing agent gives a substantial improvement in the holding power of the hairspray even though added in a minor amount compared to the amount of hairspray resin present.
  • the weight ratio of the hairspray resin to the added drag reducing agent is preferably at least 5:1.
  • the amount which may be added can be very small indeed and could be as little as one ten-thousandth of the resin, particularly when higher levels of hairspray resin are employed.
  • the weight ratio of hairspray resin to drag reducing agent will normally be in the range 5000 to 5:1.
  • the hairspray composition may also include various other ingredients well known in the art.
  • other ingredients such other ingredients as perfume; alcohol denaturants, for example benzyl diethyl 2,6-xylyl carbamoyl methyl ammonium benzoate and sucrose octa-acetate; conditioning agents such as lanolin derivatives; and plasticisers such as silicone oils having a viscosity of 10 centistokes at 25°C.
  • the inclusion of the drag reducing agent can also result in a substantial reduction in the respirable fraction of the spray.
  • Some of the particles of the aerosol cloud produced on spraying a hairspray composition may be inhaled by the user or by other persons in the vicinity.
  • the inclusion of the drag reducing agent can reduce the amount of hairspray inhaled into the lungs.
  • the proportion of the product discharged which is capable of reaching and being deposited in the lung is called herein the "respirable fraction" of the product.
  • the switches were divided into groups, the number of switches in each group corresponding to the number of hairsprays being compared.
  • the number of groups of switches varied from 3 to 5.
  • Each product was applied to the same switch in a group throughout the test, there being a minimum of three applications of the product to a switch. After each application the holding power of the spray applied to each switch was assessed by one of the assessors. After each application, e.g. the first application, each switch in a group was assessed by the same assessor but each group was assessed by a different assessor. However, for a given group the assessor was usually different for the different applications of the test products. The number of applications varied from 3 to 5.
  • the switches were left to dry and then the assessor ranked the effect of the applied spray on a 10 point scale, 1 representing best hold and 10 no hold.
  • the scored for each product were then averaged to obtain a hold value for a given product. Therefore if there were 3 groups of switches and 3 applications of test spray then the hold value was an average of 9 scores; if there are 5 groups and 5 applications are made then the hold value was an average of 25 scores. On repeating tests it was found that the hold values varied over about 0.5 unit.
  • This method of testing hairsprays is what is known as a half-head which is carried out in a hair salon.
  • a half-head which is carried out in a hair salon.
  • one side of a panellist's head was sprayed with a control product and the other side with a test product, a shield being placed centrally across the top of the head to confine a spray to one side of the head.
  • the hair hold was assessed comparatively by blowing each side of the head separately with a hand hair dryer (but without heat) and noting which side is disturbed least during blowing and least disarranged after blowing has been stopped.
  • the panellist's hair is brushed out and styled whereafter the control and test products are applied and assessed as before.
  • the procedure on the second day is then repeated on the third, fourth and fifth days.
  • the number of panellists in a test varied from 18 to 24.
  • the respirable fraction data given in Experiments 16 to 23 were determined using an Hexhlet elutriator (Brit. J. Industr. Med. 1954, 11, 284) which separates particles according to their failing velocities in the air.
  • the aerosol is drawn at a controlled horizontal velocity through a parallel plate elutriator; the vertical spacing of the plates is such that particles settling on them during the transit of the aerosol through the elutriator correspond to those which would separate aerodynamically in the upper respiratory tract of man.
  • the upper aerodynamic size limit for respirable particles collected in the Hexhlet is about 7 microns.
  • the procedure was as follows. A glass fibre filter, dried and weighed, was loaded into the Hexhlet sampler and the pack to be treated was weighed. The vacuum was adjusted so that the gauge on the Hexhlet showed about 300 mm Hg. After thoroughly shaking the pack, the product was sprayed into a cabinet fitted to the front of the Hexhlet sampler. In the case of aerosols, each sprayer was of 2 second duration, the sprays being repeated with shaking every 20 seconds for a total of 20 sprays. In the case of pump sprays the procedure was to give 10 sprays in rapid succession at the commencement of every 20 second period for a total of 200 sprays. Sampling was continued for 5 minutes after the last spray. The pack was re-weighed to give the weight of the product discharged.
