`
`Shampoo
`
`This invention relates to shampoos, and more especially to shampoos which contain a cationic
`derivative as a hair conditioning agent.
`A number of cationic derivatives have been suggested for inclusion into aqueous liquid shampoos.
`’ Such derivatives are deposited upon the hair during the shampooing process and can impart useful hair
`conditioning benefits such as improved ease of combing. Generally speaking the benefit obtained is
`dependent upon the amount of the cationic compound left on the hair after the shampooing and rinsing
`procedures. The magnitude of the benefit obtained is therefore usually dependent on the amount of the
`polymer present in the shampoo.
`Shampoo formulators have been concerned with devising ways of modifying shampoo formulae
`so as to increase the degree of deposition of the cationic hair conditioning agent so as either to
`enhance the conditioning effect or to be able to produce the same effect through the use of less of the
`conditioning agent.
`In DE—A1—2 727 255 there is described for enhancing the deposition of the
`Polymer JR cationic resins from shampoos based on alkyl ether sulphate detergents the use of various
`simple salts including the water—soluble alkali metal, alkaline earth metal and ammonium salts
`(including substituted ammonium salts) of inorganic acids and organic acids containing a carbon chain
`of not more than about 6 carbon atoms.
`to shampoo
`interest
`Cationic polymeric materials which have more recently become of
`formulators as potentially useful hair conditioning agents are cationic derivatives of poly-
`galactomannan gums. These have been described in US——A——3 589 978 and their use in certain
`shampoo formulae is disclosed in US—A— 4 016 602.
`Of the detergents used in formulating shampoos the alkyl sulphate and alkyl ether sulphate
`anionic detergents are the most widely used.
`it is with the enhancement of the deposition of the
`cationic derivatives of polygalactomannan gums from such anionic-based shampoos that the present
`invention is concerned.
`The present invention is based on our discovery that deposition onto the hair of a cationic
`polygalactomannan gum conditioning agent from a shampoo based on an alkyl sulphate or alkyl ether
`sulphate detergent is enhanced by including in the shampoo certain anionic additives.
`Accordingly the present invention provides an aqueous shampoo comprising:
`A)
`from 5% to 30% by weight of an alkyl sulphate or alkyl ether sulphate detergent;
`B)
`from 0.05% to 2% by weight of a cationic derivative of a polygalactomannan gum of the

`
`with a proviso that when the anionic additive component (C) is a sulphate the detergent component (A)
`is an alkyl ether sulphate. The group R may be an alkyl, alkenyl, cycloalkyl or cycloalkenyl group.
`Suitable amine salt forming groups constituting the group M include substituted ammonium groups,
`particularly the C1—-C4 alkyl and hydroxy C1-C4 alkyl groups especially the mono—, di- and triethyl,
`propyl, hydroxyethyl and hydroxypropyl-substituted ammonium groups.
`sulphate or
`an alkyl
`The detergent
`employed» in
`the shampoo of
`this
`invention is
`alkyl ether sulphate. Commonly used-detergents of these kinds are the C10—C18 alkyl sulphates and
`C10——C18 alkyl ether sulphates containing 2 or 3 moles of ethylene oxide. These detergents are
`generally employed in the form of their sodium, potassium, ammonium or mono—, di- or tri-ethano-
`lamine salts. Examples of these detergents are sodium lauryl sulphate, ammonium lauryl sulphate,
`mono—, di and tri—ethanolammonium lauryl sulphates, sodium lauryl ether sulphate (2 E0), sodium lauryl
`i ether sulphate (3 E0), potassium lauryl ether sulphate (2 E0), and ammonium lauryl ether sulphate (3
`E0’). The shampoo will generally contain from 8% to 25% by weight of anionic detergent.
`The cationic hair conditioning ingredient is a derivative of a polygalactomannan gum. The gum
`occurs naturally -as guar gum, the principal. component of the seed of the guar plant, cyamopsis
`tetragona/obus. The guar molecule is essentially a straight chain mannan branched at quite regular
`intervals with single membered galactose units on alternate mannose units. The mannose units are
`linked to each other by means of beta (1—4) glycosidic linkages. The galactose branching is
`accomplished through an alpha (1-6) linkage. The cationic derivatives are obtained by reaction
`between the hydroxyl groups of
`the polygalactomannan and reactive quaternary ammonium
`compounds. The degree of substitution of the cationic groups is desirably at least 0.01 and preferably
`at least 0.05, for example from 0.08 to 0.5. The quaternary ammonium compounds which can be
`used for preparing the cationic agents employed in this invention are those of the general formula
`
`R1
`

`R“——N*—R2
`

`
`or halohydrin group of the formula
`
`where R5 is a C1—C3 alkylene group and X is chlorine or bromine, 2 being an anion such as Cl‘, Br’, I‘
`or HSO ‘.
`An example of a suitable quaternary ammonium derivative is hydroxypropyltrimethylammonium
`guar gum of the formula
`
`+
`
`R-0———CH2—CH—CH,N(CH3)3Cl'
`
`IO
`
`H
`
`where R represents guar gum. Such a material is available commercially-from Celanese-Stein Hall, USA
`under the name JAGUAR C—13—S; the word JAGUAR is a trade mark. This material also has the
`CTFA designation Guar Hydroxypropyltrimonium Chloride.
`In JAGUAR C—13—S the degree of
`substitution of the cationic group is about 0.13. Another suitable material is that known as JAGUAR
`C—17 which is similar to JAGUAR C—13—S but has a higher degree ofsubstitution of cationic
`groups of about 0.25-0.31. A further example of a suitable guar derivative is the hydroxypropylated
`cationic guar derivative known as JAGUAR C-16 which as well as containing the above cationic
`quaternary ammonium groups also contains hydroxypropyl (—CH2CH(0H)CH3) substituent groups. In
`JAGUAR C——16 the degree of substitution of the cationic groups is 0.11—0.16 and the moles of
`substitution of hydroxypropyl groups is 0.8-1.1.
`The cationic polygalactomannan gum derivative is present in the shampoo of the invention in an
`amount of from 0.05% to 2% based on the weight of the shampoo. Preferred amounts are from O.1% to
`1% by weight.
`

`
`

`
`0018717
`
`Examples of the carboxylate additive which may be present in the shampoo of this invention are
`sodium octanoate, sodium laurate, sodium stearate, sodium oleate and the corresponding potassium
`and ammonium and substituted ammonium compounds. Further examples are the ethoxylated fatty
`acids and salts thereof, such as oleic acid ethoxylated with six moles of ethylene oxide.
`Typical examples of alkyl sulphates as the additive when the shampoo detergent is an alkyl ether
`sulphate are sodium lauryl sulphate and sodium stearyl sulphate. This specialised use of alkyl sulphates
`in small amounts to enhance deposition of a cationic polygalactomannan gum derivative must be
`contrasted with the use of larger amounts of these sulphates as the basic shampoo detergent.
`The anionic phosphate ester additive of the shampoo according to the invention is usually
`produced commercially as a mixture comprising the mono- and di— esters defined above. They are
`available commercially under various trade names for example-, BEROL, BRIPHOS and CRODAPHOS.
`BEROL 729 has alkyl chain lengths of 16-18 carbon atoms and contains series of 4 ethylene oxide
`units. in BRIPHOS L2D the alkyl chains are lauryl groups and it contains series of 2 ethylene oxide units.
`In BRIPHOS 03D and CRODAPHOS N3N the alkyl groups are oleyl and the ethylene oxide groups
`comprise 3 units. The weight ratio of mono-ester to di-ester may vary, typically from 1:10 to 10:1.
`Preferred phosphate esters are those in which n is 0 or an integer of from 1 to 6.
`The anionic additive is included in the shampoo in an amount of 0.1% to 3% by weight of the
`shampoo, preferably from 0.2% to 2.5% by weight.
`The shampoo of the invention may also include minor amounts of other ingredients which are
`commonly employed in shampoos, for example foam booster, thickener, opacifier, perfume, colouring
`agent, preservative, proteins, and an agent for adjusting pH, the latter usually being in the range 4 to 9
`and is preferably from 5.5 to 7.5.
`The shampoos of the invention may be prepared by dispersing the cationic polygalactomannan
`gum in water, then adding the detergent and the anionic additive. Any other ingredient may be
`incorporated along with the detergent and anionic additive, any adjustment of pH that may be desired
`conveniently being effected as the final step.
`in the experiments reported hereinafter levels of deposition of the cationic guar gum derivative
`employed therein were compared using a dye uptake test. This test is based on the substantivity of a
`polyanionic direct azo dye to a cationic substrate. Hair on which cationic guar gum derivative has
`deposited will develop a red colour when in contact with the dye. The more cationic material deposited,
`the more intense the colouration of the hair by the dye.
`
`Dye uptake test
`A 0.5 gm blond hair switch (about 10 cm long) was attached to a standard switch of hair (about
`24 cm long, 10 gm) which acted as a carrier. The combined switch, after combing and wetting with
`water, was washed with the shampoo under test. This shampooing was done in two stages. In the first
`shampooing 0.5 ml of shampoo was applied to the wet hair, the switch lathered for 30 seconds and,
`after leaving for a further 20 seconds, rinsed with water. This was repeated but using 0.4 ml of
`shampoo, any tangles being combed from the switch whilst rinsing. After removing excess water, the
`switch was dried by hanging in a drying cabinet at 50°C for one hour. The blond switch was removed
`and placed in the bottom of a 5 cm petri dish. 4 mls of a 0.1% aqueous solution of Pyrazol Fast
`Bordeaux 2BL adjusted to pH 3.5 with acetic acid were run into the dish from a burette and the hair
`probed with a spatula to ensure complete wetting of the hair by the dye solution. The switch was left in
`the solution for 30 minutes, rinsed with cold water and dried. At least two blond switches were treated
`in the above manner for each test product.
`The invention will now be illustrated by reference to the following experiments. The experiments
`demonstrate the beneficial effect of carboxylate, sulphate and phosphate additives in enhancing
`deposition of cationic guar gum derivatives from shampoos in accordance with the invention. All
`percentages are by weight.

`
`Three hair switches (8g each) were washed in a standard shampoo detergent solution (16%
`monoethanolamine lauryl sulphate) using the same method as previously described in the dye uptake
`test except that tangles were not combed out in the final rinsing stage. After removing excess water
`each switch was then combed through until free of tangles with a comb which was in association with
`an instrument which measured the total combing time. The same switches were then shampooed with
`the product under test using the same procedure. For each switch the combing time after treatment
`with the test product was expressed as a percentage of that after treatment with the standard
`shampoo. The average of the percentage values for the three switches was taken as the wet combing
`value for the test product. A different set of three switches was used for each test product. The wet
`combing values for the above four shampoos were, respectively, 69i7%, 55i1%, 134i81% and
`. 152i33%.
`The results showed that the presence of the carboxylate in the shampoo containing both resin and
`carboxylate additive led to an improvement in wet combing whereas the third shampoo containing only
`the carboxylate showed no improvement in wet combing properties over the detergent solution itself.
`This confirms that the improvement in wet combining is due to the increased deposition of the cationic
`resin brought about by inclusion in the shampoo of a carboxylate additive.

`
`By means of the dye uptake test it was shown that at all the added levels of 0.1% to 0.7% the
`phosphate ester additive increases the amount of cationic gum deposited onto hair during shampooing.
`ln a separate test it was shown that phosphate ester itself does not lead to any uptake of dye in
`the dye uptake test.
`Using the dye uptake test it was judged that the deposition of cationic resin from the above
`shampoo but containing 0.5% of the resin and no anionic additive was equivalent to that deposited
`from the shampoo containing 0.3% of resin and 0.5% of the phosphate ester. Similarly,
`the
`combination of 0.1% of the resin and 1.0% of the phosphate ester was found to be equivalent to 0.3%
`of the resin with no additive.

`inclusion of the phosphate ester in the second shampoo improved the ease of combing compared with
`the first shampoo containing no phosphate ester. The test also indicated the equivalence in ease of wet
