Abstract

Aqueous liquid cleansing compositions comprise about 8% to 50% of primary surfactant selected from anionic, cationic, zwitterionic and amphoteric surfactants, from about 0.1% to 6% of C6-C13 alcohol ethoxylate, from about 0.1% to 2% of a water-soluble polymeric thickening agent, preferably guar gum or derivative thereof and from about 0.1% to about 6% of glycerine. The compositions have desirable foaming, product stability, viscosity, pourability and skin feel characteristics.

Description

    Technical Field
  • [0001]
    This invention relates to liquid cleansing compositions and, more specifically, to aqueous liquid cleansing compositions having desirable foaming, product solubility, viscosity and skin feel characteristics.
  • Background
  • [0002]
    Liquid cleansing products are extensively used as hand cleaners, shampoos, bath foams, shower foams and for many other purposes. The present invention is concerned primarily with cleansers used for cleaning skin but is not limited to that application. The cleansers of interest are aqueous based and contain a mixture,of surfactants.
  • [0003]
    In order to achieve controlled use of a liquid cleansing composition, it is desirable to have a somewhat viscous but pourable or pumpable product. A thin, watery product is too easily spilled and wasted when used and does not have good consumer acceptance. A number of high molecular weight polymeric materials have been used in a wide variety of aqueous based products in a thickening, gelling, suspending or protective colloid functionality. Certain nonionic polymers are also known to impart desirable skin feel characteristics to the product, notably guar gum and derivatives thereof (see EP-A-67025). However, cleansing products formulated with the levels of surfactant and polymer necessary to provide satisfactory foaming, thickening and skin feel properties suffer from poor product pourability, solubility and viscosity characteristics, especially on storage at low temperatures as well as diminished thickening and viscosity control under aqueous dilution conditions in for example,shower foam compositions. Moreover, the pourability, solubility and viscosity characteristics are further aggravated by the use of fatty acid alkanolamides which are customarily added to liquid cleansing compositions for suds-boosting purposes. These problems can be mitigated to some extent by adding substantial levels of alcoholic solvents such as ethanol and the like. Nevertheless, the resulting products are not only expensive but are technically undesirable because alcoholic solvents are believed to have a tendency to cause drying of the skin.
  • [0004]
    It has now been discovered that liquid cleansing products having desirable foaming, thickening and skin feel properties together with excellent formulation pourability, solubility and viscosity characteristics at both normal and low storage temperatures are provided by the use of polymeric thickening materials, glycerine and a mixed surfactant system comprising additive levels of specified nonionic ethoxylated aliphatic alcohols.
  • Summary of the Invention
  • [0005]
    According to the present invention, therefore, there is provided an aqueous liquid cleansing composition comprising:
    • (a) from about 8% to about 50% of primary surfactant selected from anionic, cationic, zwitterionic, amphoteric and semi-polar surfactants and mixtures thereof,
    • (b) from about 0.1% to about 6% of auxiliary surfactant selected fran ethoxylated aliphatic alcohols having an average alkyl chain length of from 6 to 13 carbon atans,
    • (c) from about 0.1% to 2% of a water-soluble polymeric thickening agent, and
    • (d) from about 0.1% to about 6% of glycerine.
  • [0006]
    The water-soluble thickening agent useful in the present compositions can be a nonionic or cationic polymeric thickening agent or a mixture thereof. Preferred nonionic water-soluble polymers are selected from guar gum, hydroxypropyl guar gum, methyl cellulose, methyl hydroxypropyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, locust bean gum, starch, starch amylose, hydroxyethylamylose and polyoxyethylene. The polymer is a high molecular weight material (mass-average molecular weight being generally from about 50,000 to about 5,000,000, preferably from about 100,000 to about 1,000,000), and its thickening ability is preferably such that a 10%, preferably a 5% and more preferably a 1% dispersion of the polymer in water at 20°C exceeds about 1 Pa.s (10 poise) at a shear rate of 10-2sec-1.
  • [0007]
    Highly preferred polymers herein are guar gum and derivatives thereof which provide a highly desirable smooth slippery skin feel to the products. Guar gum is a naturally occurring material which is the principal component of the seed of the'guar plant. Guar gum is extracted from the guar seed and purified. Guar gum is a high molecular weight carbohydrate polymer or polysaccaride made up of mannose and galactose units linked together. The guar molecule is essentially a straight chain of mannose units linked to each other by means of beta (1-4) glycosidic linkages. Galactose units branch from alternate mannose units through alpha (1-6) linkages with the mannose units.
  • [0008]
    The desired skin feel of the liquid cleansing products is preferably obtained by using hydroxypropyl guar gum. In the guar gum molecule, each mannose and galactose unit has from 2-4 hydroxyl groups, depending on where the units are located in the polymer chain. Guar gum derivatives are produced by reacting guar gum such that substitution of chemical moieties occurs on some of these hydroxyl groups. Hydroxypropyl guar gums are a family of materials with hydroxypropyl groups substituted for some of the hydroxyl groups. The term "degree of substitution" is used to indicate the average number of hydroxypropyl groups which occur on each of the sugar units in the polymer molecule. The preferred hydroxypropyl guar gum used in the present invention has a degree of substitution of from about 0.3 to 1.2; especially preferred is hydroxypropyl guar gum with a degree of substitution of about 0.6. Such a material is available commercially as Jaguar HP-60 from Meyhall Chemical Ltd.
  • [0009]
    Preferred cationic polymeric thickening agents herein are selected from hydroxypropyltrimethylammonium guar gums, quaternized cellulose ethers, homopolymers of dimethyl diallyl ammonium chloride, co-polymers of dimethyl diallyl ammonium chloride and acrylamide, quaternized vinyl pyrrolidone acrylate or methacrylate copolymers of amino alcohol, and polyalkylene imines, in particular the polyethylene imines and the ethoxy polyalkylene imines. Of these, highly preferred are hydroxypropyl trilæthyl ammonium guar gum, quaternized cellulose ethers and mixtures thereof. Mixtures of the above specified cationic and nonicnic thickening agents are also suitable herein.
  • [0010]
    By way of exemplification, cationic polymers preferred for use herein include cationic guar gums such as hydroxypropyl trimethyl ammonium guar gum (d.s. of from 0.11 to 0.22) available commercially under the trade names Jaguar C-14-S(RTM) and Jaguar C-17(RTM), and also Jaguar C-16(RTM), which contains hydroxypropyl substituents (d.s. of from 0.8-1.1) in addition to the above-specified cationic groups, and quaternized cellulose ethers available commercially under the trade names Ucare Polymer JR and celquat. Other suitable cationic polymers are homopolymers of dimethyldiallylammonium chloride available commercially under the trade name Merquat 100, copolymers of dimethyl aminoethylmethacrylate and acrylamide, copolymers of dimethyldiallylammonium chloride and acrylamide available commercially under the trade names Merquat 550 and Merquat S, quaternized vinyl pyrollidone acrylate or methacrylate copolymers of amino alcohol available commercially under the trade name Gafquat, and polyalkyleneimines such as polyethylenimime and ethoxylated polyethylenimine.
  • [0011]
    The quantity of polymer material used in the liquid cleansing products of this invention is from about 0.1% to about 2%, especially from about 0.2% to about 1%. A preferred range of usage for guar gum and its derivatives is from about 0.3% to about 0.7%.
  • [0012]
    The liquid cleansing compositions of this invention comprise a primary surfactant selected from anionic, cationic, zwitterionic and amphoteric surfactants and mixtures thereof, together with an auxiliary surfactant which is a specific type of nonionic surfactant material. The primary surfactant comprises from about 8% to about 50%, preferably fran about 10% to about 30%, more preferably from about 15% to about 25% by weight of the composition; the auxiliary surfactant comprises from about 0.1% to about 6%, preferably from about 0.5% to about 4%, more preferably from about 1% to about 3% by weight of the composition.

  • [0015]
    The alkyl sulphate component is preferably a primary alkyl sulphate in which the alkyl group contains about 10-16 carbon atoms, more preferably an average of 12-14 carbon atoms. The alkyl group may be linear or branched in configuration. C10-C16 alcohols, derived from natural fats or Ziegler olefin build-up or OXO synthesis, form suitable sources for the alkyl group. Examples Of synthetically derived materials include Dobanol 23 (RIM) sold by Shell Chemicals (UK) Ltd, Ethyl 24 sold by the Ethyl Corporation, a blend of C13-C15 alcohols in the ratio 67% C13, 33% C15 sold under the trade name Lutensol by BASF GmbH and Synperonic (RTM) by ICI Ltd, and Lial 125 sold by Liquichimica Italiana. Examples of naturally occurring materials from which the alcohols can be derived are coconut oil and palm kernel oil and the corresponding fatty acids.
  • [0016]
    The level of the alkyl sulphate component generally lies in the range of from about 4% to about 20% by weight of the composition, more generally from about 4% to about 16% by weight. In one preferred compositional aspect of the invention in which alkyl benzene sulphonate is also incorporated, the usage level lies in the range from about 8% to about 12% by weight, most preferably in the range from about 8% to about 11% by weight. In another compositional aspect of the invention in which a sulphonate component is not present, the alkyl sulphate level lies in the range from about 12% to about 20%, more preferably from about 14% to about 18% by weight.
  • [0017]
    For the purposes of the present invention any alkali metal, alkaline earth metal, ammonium or substituted ammonium cation can be used in association with the alkyl sulphate. In particular, the alkyl sulphate can be associated with a source of magnesium ions either introduced as the oxide or hydroxide to neutralise the acid, or added to the composition as a water soluble salt. In practice the magnesium ion will be present at a level of from about 0.001% to about 0.70% by weight, preferably from 0.01% to 0.1% by weight of the composition.

  • [0019]
    The alkyl ethoxy sulphate surfactant component preferably comprises a primary alkyl ethoxy sulphate derived from the condensation product of a ClO-Cl6 alcohol with an average of up to 6 ethylene oxide groups. The C10-C16 alcohol itself can be obtained from any of the sources previously described for the alkyl sulphate component. It has, however, been found preferable to use alkyl sulphate and alkyl ether sulphate in which the carbon chain length distributions are the same. C12-C13 alkyl ether sulphates are preferred and the level of alkyl ethoxy sulphate in the composition lies generally between about 8% and about 25% by weight of the compositions. In compositions additionally incorporating an alkyl benzene sulphonate surfactant, the level of alkyl ethoxy sulphate generally lies in the range from 9% to 15% by weight.
  • [0020]
    Conventional ethoxylation processes result in a distribution of individual ethoxylates ranging from 1 to about 10 ethoxy groups per mole of alcohol, so that the desired average can be obtained in a variety of ways. Blends can be made of material having different degrees of ethoxylation and/or different ethoxylate distributions arising from the specific ethoxylation techniques enployed and subsequent processing steps such as distillation. For example, it has been found that approximately equivalent sudsing to that given by a blend of alkyl sulfate and alkyl triethoxy ether sulfate can be obtained by reducing the level of alkyl sulfate and using an alkyl ether sulfate with an average of approximately two ethoxy groups per mole of alcohol. In preferred compositions in accordance with the present invention the average degree of ethoxylation is from about 0.5 to about 4, more preferably from about 0.8 to about 2.0.

Examples of compounds falling within this definition are 3-(N,N-dimethyl-N-hexadecylammonio) propane-l-sulfonate and 3-(N,N-dimethyl-N-hexadecylammonio)-2-hydroxy propane-1-sulfonate.
  • [0023]
    Amphoteric synthetic detergents can be broadly described as derivatives of aliphatic secondary and tertiary amines, in which the aliphatic radical may be straight chain or branched and wherein one of the aliphatic substituents contains from about 8 to 18 carbon atoms and one contains an anionic water solubilizing group, e.g., carboxy, sulfo, sulfato, phosphato, or phosphono. Examples of compounds falling within this definition are sodium-3-dodecylaminopropionate and sodium-3-dodecylaminopropane sulfonate.
  • [0024]
    Other suitable primary surfactants hereih are the long chain tertiary amine oxides of general formula wherein R1 represents alkyl, alkenyl or monohydroxy alkyl radical of from 8 to 18 carbon atoms optionally containing up to 10 ethylene oxide moieties or a glyceryl moiety, and R2 and R3 represents alkyl of from 1 to 3 carbon atoms optionally substituted with a hydroxy group, e.g., methyl, ethyl, propyl, hydroxy ethyl, or hydroxy propyl raidcals.

The amine oxide surfactants are generally referred to as semi-polar although in acid to neutral media they behave akin to cationic surfactants.
  • [0025]
    The auxiliary surfactant component of the invention is a C 6-C13 aliphatic alcohol ethoxylate generally containing an average (Eav) of from about 1.5 to about 25, preferably from about 2 to 15 and more preferably from about 6 to about 10 moles of ethylene oxide per mole of alcohol. The auxiliary surfactant preferably contains not more than about 1% by weight of unethoxylated alcohol when the ethoxylated alcohol contains an average of less than 9 moles of ethylene oxide and not more than about 2% by weight of unethoxylated alcohol when the ethoxylated alcohol contains an average of 9 or more moles of ethylene oxide per mole of. alcohol. Such surfactants are preferred from the viewpoint of low temperature stability, the unethoxylated content preferably being less than about 0.7%, and more preferably less than about 0.5%. The unethoxylated material can be removed by vacuum distillation.
  • [0026]
    The starting alcohol may be a primary or secondary alcohol but is preferably a primary alcohol which may be derived from natural or synthetic sources.

  • [0030]
    Although the addition of fatty acid alkanolamides (e.g. C10-C16 mono- and di-C2-C3 alkanolamides) in higher levels has a generally deleterious effect on formulation physical characteristics, nevertheless such materials can be added for additional suds-boosting effect and thickening effect provided the amide is maintained at low concentration in product, preferably no more than about 4% by weight, more preferably less than about 3% by weight.
  • [0031]
    Where the composition of a liquid cleansing product will be in contact with the skin of the users, it is preferred that the cleansing product be formulated to provide a pH in use within the range of from about 4 to about 10, depending upon the particular surfactant or materials employed. Especially preferred is a pH in the range of 5 to 7. Any of a large number of known substances can be used to adjust the pH of the liquid cleansing product, e.g., sodium hydroxide, citric acid, generally at a level of up to about 0.5% of the product composition. Perfumes may be used in formulating the liquid cleansing products, generally at a level of about 0.1% to about 5% of the product composition. Colorants may also be used in the liquid cleansing products. Opacifiers, e.g., ethylene glycol distearate, polystyrene latex, generally at a level of about 0.2% to about 2.0% of the product composition, may be used in the liquid cleansing products to provide them with an opaque or pearlescent appearance.-Preservatives, e.g., EDTA, methyl paraben, propyl paraben, Germall 115, Kathon, generally at a level of less than 1%, may be incorporated in the liquid cleansing products to prevent microbiological growth in the products.
  • [0032]
    The liquid cleansing products of the present invention generally contain at least about 42% water, preferably from about 60% to about 90% water.
  • [0033]
    The invention is illustrated in the following non-limative examples in which all parts and percentages are by weight unless otherwise specified: Hot Premix
  • [0034]
    A. portion of the alkyl sulphate (supplied as a 28% aqueous solution) is heated in a premix tank to about 60°C and the fatty alcohol ethoxylate and glycerine are added thereto with agitation and heating to maintain a temperature of about 60°C. The preservative is then added and the premix is heated to about 65°C at which temperature coconut monoethanolamide, if present, is added. Ethyleneglycoldistearate is added after further heating to a temperature of about 65°C to 70°C.
  • Main Mix
  • [0035]
    The alkyl ether sulphate (supplied as a 28% active) and the remaining alkyl sulphate are added to a main mix tank together with a water slurry of the guar material. Finally the citric acid, and magnesium chloride, if present, are added.
  • [0036]
    The premix is then added with agitation at a temperature of about 70°C to the main mix, the combined mixture is rapidly cooled in a heat exchanger and dyes and perfume are added to form the finished product.
  • [0037]
    The resulting products have desirable foaming, thickening and skin feel properties together with excellent formulation pourability, solubility and viscosity characteristics at both normal and low storage temperatures as well as good thickening and viscosity control when diluted with water under typical shower foam usage conditions.
  • [0038]
    The above Examples are repeated but the polymer is added as the final component in the hot premix rather than the main mix and the premix is agitated for at least 15 minutes prior to addition to the main mix. The resulting products retain the advantages described above but have a higher viscosity at ambient temperatures.
