The use of polymeric gums including guar gums, in shampoo compositions ls well known. U.S. Pa~ents disclosing such compositions are 3,6j0,985, April 25, 1972 to Olson et 21; 3,697,644, October 10, 1972 to Laide~an; 3,932,610, January 13, 1976 to Rudy et al;

While it is known to use polymeric gums in shampoos there is no teaching or suggestion of the problems encountered with hydroxypropyl guar gums in making stable, good performing shampoo composltions or solutions thereto.

It is still a further object of the present invention to provide shampoos which deliver good hair condition.
These and other objects of the present inven-tion will become obvious from ~he detailed descrip-tion which follows.
DISCLOSURE OF THE INVENTION
The present invention provides a liquid cleansingproduct comprising by weight:
~A) from about 0.1~ to about 1.5~ of a hydroxypropyl guar gum~
(B) from about 0.5% to about 20% of an alcohol containing from 1 to 4 carbon atoms and from 1 to 3 hydroxy groups;
(C) from about 10% to about 50% of a surfactant;
(D) from about 0.1% to about 7% of an electrolyte; and (E) wa~er, in amount sufficient to make up 100%.
A specific example of such li~uid cleansing product is a shampoo composition.
DETAILED DESCRIPTION OF THE INVENTION
.
Hydroxypropyl Guar Gum The hydroxypropyl guar gums useful in the com-positions of the present invention may be formed by reacting propylene oxide with guar gum. Such a process is described in U.S. Patent 3,748,201, issued October 8, 1971 to Jordan.

.~

~8~

Guar gum is naturally occurring in the seed of the guar plant and is a high molecular weight carbohydrate poly~er or polysaccharide made up of mannose and galac-tose units linked together. The guar molecule is 5 essentially a straight chain of mannose units linked to ea~h other by means of ~eta (1-4~ glycosidic linkages.
Galactose units branch from alternate mannose units through alpha (1-6) linkages with the mannose units.

In the guar gum molecule, eaeh mannose and galactose 10 unlt has from 2 - 4 hydroxyl groups, averaging 3, depending on where it is located in the polymer chain.
Guar gum derivatives are produced by reacting guar gum such that substitution of chemical moieties oecurs on some of these hydroxyl units. Hydroxypropyl guar gums 15 are a ~amily of materials with hydroxypropyl groups substituted for some of the hydroxyl units. The term "molar substitution" is used to indicate the average number o~ hydroxypropyl units occurring on any single ring of the pol~mer molecule. It is preferred that the 20hydroxypropyl guar gum used in the present invention hàve a molar substitution of about 0.1 to about 1.0, preferably from about 0.4 to about 0.9.

Suitable hydroxypropyl guar gums are offered by Celanese Plastics & Specialties Company under the name 25Jaguar ~ A preferred material is Jaguar ~ P-60 having molar substitution of about 0.6.

The amount of hydroxypropyl guar gum found useful in the present compositions i~ from about 0.1% to about l.5%, preferably from about 0.6% to about l.0~.

f~

Alcohol A second essential component of the present compositions is an alcohol containing from about 1 to about 4 carbon atoms and rrom about 1 to abou~
3 hydroxyl groups Preferably the number of carbon atoms is from about 2 to about 3 while the number of hydroxyl groups is from about 1 to about 2~ The alcohol is present at a level of from about 0.5% to about 20~/o~ preferably from about 1% to about 6% in the instant compositions, Examples o~ suitable alcohols are ethanol, methanol, propanol, isopropanol, glycerin and ethylene glycol. The most preferred alcohol is ethanol, Surfactant The third essential component of the present compositions is a surfactant. The surfactant~
which may be selected from any of a wide variety of anionic (soap and nonsoap), amphoteric, zwit-terionic, nonionic and, in certain instances,cationic surfactants, is present at a level of from about 10% to about 50%, preferably from about 10% to about 20%.
Examples of suitable soaps are the sodium, 25 potassium, ammonium and alkanol ammonium salts of higher fatty acids (those having 10 - 20 carbon atoms).
Anionic nonsoap surfactants can be exemplified by the alkali metal salts of organic sulfuric reaction pro-30 ducts having in their molecular structure an alkyl radi-: cal containing from 8 - 22 carbon atoms and a sulfonic , . ... , . ,~ ..... .. .

84~

-- s --acid or sulfuric acid ester radlcal (included in the term alkyl is the alk-~l portion of higher acyl radicals). Preferred are the sodium, ammonium, potassium or triethanolamine al~yl sulfates, especially those obtained by sulfating the higher alcohols (C8 _ C18 carbon atoms), sodium coconut oil atty acid monoglyceride sulfates and sulfonates; sodium or potassium salts of sulfuric acid esters of the reaction produc~ of 1 mole of a higher fatty alcohol (e.g., tallow or coconut oil alcohols) and 1 to 12 moles of ethylene oxide; sodium or potassium salts of alkyl phenol ethylene oxide ether sulfate with 1 to 10 units of ethylene oxide per molecule and in which the alkyl radicals contain from 8 to 12 carbon atoms, sodium alkyl glyceryl ether sulfonates; the reaction product of fatty acids having from 10 to

2~ carbon atoms esterified with isethionic acid and neutralized with sodium hydroxide; water soluble salts of condensation products of fatty acids with sarcosine; and others known in the art.
Nonionic surfactants can be broadly defined as compounds produced by the condensation of alkyl-ene oxide groups (hydrophilic in nature) with an `organic hydrophobic compound, which may be ali-phatic or alkyl aromatic in nature. Examples of preferred classes of nonionic surfactants are:
1. The polyethylene oxide condensates of alkyl phenols, e.g., ~he condensation products of alkyl phenols having an al~yl group containing from about 6 to 12 carbon atoms in either a straight chain or branched chain configuration, with ' ~ig , .. , . .. ., . . . . , . ,, ................... . . ~
-~L8~

ethylene oxide, the said ethylene oxide being present in amounts equal to 10 to 50 moles of ethylene oxide per mole of alkyl phenol. The alkyl substituent in such compound$ may be derlved from polymeri~ed propyl~ne, diisobutyl-ene, octane, or nonane, for example.

2. Those derived from the condensatlon of ethylene oxide with the product resulting from the reaction of propylene oxide and ethylene diamine products which may be varied in composition depending upon the balance between the hydro-phobic and hydrophilic elements which is de-sired. For example, compounds containing from about 40% to about 80% polyoxyethylene by weight and having a molecular weight of from about 5,000 to about 11,000 resulting from the reaction of ethylene oxide groups with a hydro-phobic base constituted of the reaction product of ethylene diamine and excess propylene oxide, said base having a molecular weight of the order of 2,500 to 3,000, are satisfactory.

3. The condensation product of aliphatic alcohols having from 8 to 18 carbon atoms, in either straight chain or branched chain configuration, with ethylene oxide, e.g., a coconut alcohol ethylene oxide condensate having from 10 to 30 moles of ethylene oxide per mole of coconut alcohol, the coconut alcohol fraction having from 10 to 14 carbon atoms. Other ethylene ox-ide condensation products are ethoxylated fatty 34~

aci*d esters of polyhydric alcohols (e.g."Tween 20'~polyoxye~hylene (20) sorbit2n ~onolaurate.
