Description
NON-AEROSOL PUMP HAIR SPRAY COMPOSITIONS
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a non-aerosol, pump hair spray composition which can be applied as a fine spray mist, which dries rapidly, and which provides superior hair holding power, without nozzle clogging.
2. Description of the Prior Art
Aerosol hair spray products contain a hair spray composition which includes a hair fixative resin and a volatile propellant. These cosmetic products apply the resin as a fine, dispersed spray which exhibits excellent hair holding power. However, the propellants used therein are known to adversely affect the ozone layer of the atmosphere. For this reason, it is desired to provide non-aerosol, pump hair spray compositions which exhibit the same advantageous properties as aerosol hair sprays.
Non-aerosol hair spray compositions are applied by means of a pressure actuated pump nozzle. However, commercially available pumps for non-aerosol application have restricted nozzle orifices which limits its use to resin compositions having a low solids content. Unfortunately, the restriction on resin solids content reduces the holding power of the hair spray. Furthermore, if the solids content of the resin composition is increased, the spray pattern becomes streamed rather than sprayed. This effect is caused by the inability of the
nozzle to effectively break up hair spray compositions of high solids content. Furthermore, nozzle clogging becomes evident if the solids content is increased. Accordingly, hair spray resins used in present non-aerosol hair spray products generally are present at about a 5% solids- level, which enables only relatively weak hair holding power and poor curl retention.
Jui-Chang Chuang, in U.S. Patent 4,689,379, described the preparation of terpolymeric hair fixative resins for use particularly in aerosol spray formulations. The terpolymer resin comprised a vinyl acetate/mono-C4-C5 alkyl maleate/isobornyl acrylate or methacrylate, preferably in a molar ratio of 1:0.75:0.1. The hair spray compositions included such resins in concentrations between 0.5% and about 10% solids, preferably 2.5%-5%, and required a relative viscosity (RV) of greater than 1.30, preferably 1.64 (K = 48.5). A resin which had a relative viscosity of 1.07 (K = 15) exhibited only very poor curl retention (Example 14) .
Accordingly, it is an object of this invention to provide a non-aerosol pump hair spray composition and cosmetic product which can be applied to the user as a fine spray mist, which dries rapidly, and which has superior hair holding power, without nozzle clogging.
A particular object herein is to provide a hair spray composition having a high solids content hair fixative resin which can be applied through a nozzle pump as a fine mist and which exhibits excellent hair holding power.
SUMMARY OF THE INVENTION
What is described herein is a non-aerosol hair spray composition capable of being applied by the user as - fine spray mist which dries rapidly and provides effectiv<
hair holding power without nozzle clogging. The composition includes from about 6 to 20% of a hair fixative resin which is a terpolymer of a vinyl ester, a water insoluble or water miscible alkyl maleate half ester and an acrylate or ethacrylate ester of a saturated hydroxylated bicyclic hydrocarbon having a relative viscosity of from 1.10 to below 1.30, the carboxyl groups of which are 10 to 100% neutralized with a water soluble base and about 65 to 94% of ethanol solvent.
DETAILED DESCRIPTION OF THE INVENTION
In accordance with the present invention, the resins utilized in the non-aerosol pump hair spray compositions are terpolymer resins described in detail in U.S. 4,689,379. The terpolymer resin is a random or alternating structure comprising essentially a vinyl ester, a water insoluble or water miscible alkyl maleate half ester and an acrylate or methacrylate ester of a saturated hydroxylated bicyclic hydrocarbon in a molar ratio of about 1:0.35-1:0.05-0.25.
Acrylate and/or methacrylate esters of isoborneol, exonorborneol and endo-norborneol are preferred and the isobornyl ester is the most preferred. The preferred bicyclic compounds are those having a hydrocarbon bridge and are generally defined by the formula
wherein each of R, R-^ R2 and R3 is hydrogen or methyl.
The molar ratio of vinyl ester to the bicyclic acrylate or methacrylate monomer in the terpolymer should be between about 4:1 and about 20:1. A particularly preferred molar ratio of vinyl acetate/mono-C4 to C5 alkyl maleate/isobornyl acrylate or methacrylate is about 1:0.6-0.8:0.08-0.12, e.g. 1:0.75:0.1.
Illustrative of the water insoluble or water miscible alkyl maleate half ester monomers of this invention are the propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl and decyl half esters; although the n-butyl and n-pentyl half esters are the most preferred.
Examples of the vinyl ester onomeric component are those containing 4 to 14 carbon atoms which include vinyl acetate, vinyl propionate, vinyl isobutyrate, vinyl butyrate, vinyl hexanoate, vinyl pivalate, vinyl laurate and vinyl neodecanoate, of which vinyl acetate is the most preferred.
The resins herein are prepared by a solution polymerization process which provides the resin within the requisite relative viscosity range and K values and solids content. The process comprises adding the monomers, individually or premixed in the above proportions in a suitable solvent for both the monomers and the terpolymer, for example, acetone, ethanol or mixtures thereof, wherein they are polymerized in the presence of a free radical initiator under conditions of agitation at a temperature of between about 40° and about 90°C. , preferably between about 50° and about 70°C. The initiator can be added to the monomer mixture before or after the monomers have been charged into the solution medium. The reaction is carried out under an inert atmosphere which can be maintained by purging with nitrogen to eliminate air and oxygen.
The polymerization reaction is carried under constant agitation over a period of from about 4 to 24 hours, although usually 8 to 16 hours is sufficient to complete the reaction and form a terpolymer product. At this point, ethanol is added and acetone solvent is removed by distillation until the reactant temperature reaches about 60° to 90°C, preferably about 70° to 80°C. The terpolymer product has a relative viscosity of 1.10 to less than 1.30, preferably about 1.20, a K value in the range of 18 to 30, preferably about 27, and a resin solids content of about 40 to 80, preferably about 50% solids.
The terpolymeric resins thus prepared by solution polymerization with the predetermined relative viscosity range and molecular weights are employed as the active ingredient in a non-aerosol pump hair spray formulation and employed in a cosmetic product fitted with a suitable nozzle pump valve. The present resins are employed in concentrations between about 6 to 20% solids, preferably 8 to 15% solids. Such cosmetic products can be used over an extended period of time to generate fine spray mists without experiencing any nozzle clogging.
The hair treatment formulations herein include a solvent for the resin, such as a lower alcohol, e.g. ethanol, an aqueous ethanol solution, isopropanol and the like, etc. Generally aqueous ethanol is preferred and in an amount of about 65 to 94% of the formulation.
In preparing the hair treatment formulations, the terpolymers are at least 10% neutralized with a water soluble base to provide water solubility and shampoo removability, and preferably, about 50 to 100% neutralized. Examples of suitable water-soluble bases
include ammonium hydroxide, sodium hydroxide, potassium hydroxide; mono-, di-, and tripropanolamine, dimethyl- steara ine, aminometh lpropanol, aminomethylpropanediol, or mixtures thereof. Water-soluble organic bases are preferred and aminomethylpropanol is especially preferred.
Improved results are obtained when plasticizer for the polymer is added to the formulation. When used, about 0.05 to 0.5 percent by weight, based on the weight of the copolymer, of either an ester or silicone plasticizer is added. Suitable ester plasticizers include isocetyl stearate, diisopropyl adipate, isohexyl laurate, isohexyl palmitate, and isocetyl stearate. Isocetyl stearate is preferred. Suitable silicones include dimethicone copolyol (Silicone Fluid SF-1066, General Electric Co.) which is the reaction product of dimethyl siloxane and ethylene oxide, propylene oxide and/or glycols. Some degree of plasticization is achieved by the water present in the compositions of the invention.
The formulations are charged into a suitable container and fitted with a pump valve. When operated through a pressure release nozzle, the formulations provides a fine spray mist and avoids nozzle clogging when the resins are employed within the predetermined relative viscosity range and solids content defined above.
Having thus generally described the invention, reference is now had to the following examples which provide specific and preferred embodiments but which are not to be construed as limiting to the scope of the invention as more broadly described above and in the appended claims.
