Definitions

  • the present invention relates to aqueous liquid cleansing compositions containing specific fatty acid soaps.
  • aqueous liquid cleansing compositions containing specific fatty acid soaps.
  • compositions suitable for cleansing human skin and hair comprising a combination of certain long and short chain fatty acid soaps.
  • Such compositions besides being mild, provide a good lather.
  • aqueous cleansing compositions were classified according to the amount of lather they produced during use; those giving the highest lather volume considered to be the superior products.
  • the need to provide products which, as well as showing good foaming/lather, are mild to hair and skin treated therewith has been identified.
  • liquid cleansing compositions which show good lather and are mild can be formed by the use of a short chain fatty acid soap in combination with a long chain fatty acid soap. It is surprising that the short chain fatty acid soap which, when used by itself, shows no effective lather can improve the lather performance of the long chain fatty acid soap.
  • an aqueous liquid cleansing composition comprising
  • composition comprises not more than 3wt% C 12 fatty acid soap based on the aqueous cleansing composition, not more than 15wt% C 12 fatty acid soap based on the total fatty acid soap and the weight ratio of (a) to (b) is within the range 1:20 to 5:1.
  • the weight ratio of (a) : (b) is in the range 1:20 to 1:1.
  • the short chain fatty acid soap is preferably a sodium or potassium salt or a substituted ammonium ion (e.g. triethanolamine) of, for example, a fatty acid derived from animal or vegetable sources obtained by a distilled fatty acid route.
  • a substituted ammonium ion e.g. triethanolamine
  • the short chain fatty acid soap is a C 6 -C 8 fatty acid soaps, most preferably a C 8 fatty acid soap.
  • the long chain fatty acid soap is preferably a sodium or potassium salt or a substituted ammonium ion (e.g. triethanolamine) of, for example, a fatty acid derived from animal or vegetable sources obtained by a distilled fatty acid route.
  • a substituted ammonium ion e.g. triethanolamine
  • the long chain fatty acid soap is a C 14 or C 18:1 (C 18 mono-unsaturated) fatty acid soap.
  • the total level of fatty acid soap present in the composition should preferably be in the range 1 to 40 wt%, preferably 5 to 30 wt%.
  • the short fatty acid soap is a C 8 material and the long chain fatty acid soap a C 14 or C 18:1 material. Not only is this chain blended system milder than a composition based on a C 12 fatty acid soap but it also shows comparable lather performance. Low levels of C 12 fatty acid soap not more than 3wt%, preferably not more than 2wt%, based on the total composition, and not more than 15wt% based on the total fatty acid soap may be added to the mixed soap system. At these levels the presence of C 12 fatty acid soap may improve the lather performance even further without having a detrimental effect on the mildness of the composition.
  • compositions according to the invention will also include a cosurfactant .
  • the cosurfactant can be selected from any known surfactant suitable for topical application to the human body and is selected from anionic, nonionic, zwitterionic and cationic surfactants and mixtures thereof. Mild surfactants, ie. surfactants which do not damage the stratum corneum, the outer layer of skin, are particularly preferred.
  • Preferred anionic cosurfactants include fatty acyl isethionates, alkyl ether sulphates, alkyl glyceryl ether sulphate, sulphosuccinates, taurates, sarcosinates, sulphoacetates, alkyl phosphate, alkyl phosphate esters, acyl lactylate, alkyl glutamates and mixtures thereof.

  • Suitable nonionic surface active agents include alkyl polysaccharides, lactobionamides, ethyleneglycol esters, glycerol monoethers, polyhydroxyamides (glucamide) , primary and secondary alcohol ethoxylates, especially the C 8-20 aliphatic alcohols ethoxylated with an average of from 1 to 20 moles of ethylene oxide per mole of alcohol.
  • Preferred zwitterionic detergents are those which have an alkyl or alkenyl group of 7 to 18 carbon atoms and comply with an overall structural formula:
  • R 1 is alkyl or alkenyl of 7 to 18 carbon atoms
  • R 2 and R 3 are each independently alkyl, hydroxyalkyl or carboxyalkyl of 1 to 3 carbon atoms
  • m is 2 to 4
  • n is 0 or 1
  • X is alkylene of 1 to 3 carbon atoms optionally substituted with hydroxyl
  • Zwitterionic detergents within the above general formula include simple betaines of formula:
  • R 3 where m is 2 or 3 .
  • R 1 , R 2 and R 3 are as defined previously.
  • R 1 may, in particular, be a mixture of C 12 and C 14 alkyl groups derived from coconut so that at least half, preferably at least three quarters of the groups R 1 have 10 to 14 carbon atoms.
  • R 2 and R 3 are preferably methyl.
  • a further possibility is a sulphobetaine of formula:
  • R 1 , R 2 and R 3 in these formulae are as defined previously.
  • compositions of the invention may comprise a structurant, i.e. a material added to increase the viscosity at low shear, such as less than Is "1 .
  • Suitable materials include swelling clai :, for example laponite; fatty acids and derivatives thereof and, in particular, fatty acid monoglyceride polyglycol ethers cross-linked polyacrylates such as Carbopol (TM) (polymers available from Goodrich) ; acrylates and copolymers thereof, polyvinylpyrrolidone and copolymers thereof; polyethylene imines; salts such as sodium chloride and ammonium sulphate; sucrose esters; gellants; and mixtures thereof.

  • Suitable electrolytes include alkali and alkaline earth salts such as halides, ammonium salts and sulphates.
  • compositions according to the invention may also comprise a thickening agent, ie a material which maintains the viscosity of the composition as the shear rate thereof is increased during use.
  • Suitable materials include cross- linked polyacrylates such as Carbopol (TM) (polymers available from Goodrich) ; fatty acids and derivatives thereof and, in particular, fatty acid monoglyceride polyglycol ethers; natural gums including alginates, guar, xanthan and polysaccharide derivatives including hydroxy ethyl cellulose, carboxy methyl cellulose and hydroxypropyl guar; propylene glycols and propylene glycol oleates; salts such as sodium chloride and ammonium sulphate; glycerol tallowates; and mixtures thereof.
  • TM Carbopol
  • compositions of the invention include opacifiers; preservatives such as para-hydroxy benzoate esters; antimicrobials such as antioxidants such as butyl hydroxy toulene; bactericides; humectants such as glycerol and sorbitol; waxes; plant extracts such as Aloe Vera, witch hazel and elderflower; colourants; and perfumes.

  • compositions of the invention may be formulated for washing the skin, for example, bath or shower gels; handwashing compositions; facial washing compositions; pre- and post- shaving products; and rinse-off and wipe-off skin care products.
  • compositions of the invention will generally be pourable liquids or semi-liquids, for example, pastes and will, preferably, have a viscosity n the range 100 to 100,000 mPas measured at a shear rate of 10s "1 and 25°C in a Haake Rotoviscometer RV20.
  • Betaine was cocoamidopropyl betaine BDF-H 30% dispersion ex Nippon Oils and Fats. Examples 1-3
  • test composition 2.5 ml was dosed directly onto dry gloves, and the panellist rubbed his or her hands together to generate lather.
  • the lather volume was measured by submersion of the panellist hands under a calibrated collecting funnel.
  • Example C the formulation comprising solely a C 12 soap (example C) was the highest foaming system of the comparative formulations.
  • Example D C 14 soap foamed less well than the C 12 system and the C 8 and C 10 (examples A and B) produced no foam.
  • the C 8 /C 14 blends produced a lather volume which was, better than that from a pure C 12 system.
  • the results demonstrate that C 8 soap boosts the lather performance of a C 14 soap system.
  • E and F are comparative examples The lather performance of these formulations was determined using the same method as described in Examples 1 to 3 except 0.5g of the test product was dosed onto wet gloves.
  • test products' skin mildness properties were evaluated using a block design in a standardised Flex Wash test.
  • the Flex Wash test procedure consisted of three daily one minute washes of the antecubital fossa (flex area of elbow) . This method is an "exaggerated use” method designed to differentiate very mild products. Erythemal response varies only slightly with temperature and humidity fluctuations making the protocol suitable for year round testing.
  • Panellist flex areas must be free of any skin condition (eczema, dryness, irritation, cuts or abrasions) .
  • Any skin condition eczema, dryness, irritation, cuts or abrasions.
  • An antihistamines, anti- inflammatory drugs (more than 8 per week) or topical, oral or injectable cortisone on a regular basis was excluded from the study.
  • the 3 test products were assigned to wash sites (left or right arm) using a block design.
  • the panellist was instructed to moisten the left flex area and a sponge. 0.5 g of product was then dispensed onto the sponge and the "dosed" sponge was placed in the panellist's right hand. The panellist then washed the left flex area for exactly one minute. Thereupon, the flex was rinsed and patted dry. This washing procedure was repeated on the right arm with the appropriate composition. Thus, both arms are tested simultaneously. Washing by this procedure was repeated three times daily for 5 consecutive days for a total of 15 washes. Treatment times were scheduled 1.5 hours apart. Each test site was evaluated immediately prior to washing and 4 hours after the third daily wash.
  • each test site was treated in the prescribed method until a grading of "2" or greater was attained or 15 washings had been completed. When a score of "2" or greater was attained, the treatment was discontinued on that flex. The final score was then carried through for all remaining evaluations. The remaining flex was washed until either a grading of at least "2" or 15 treatments were attained, whichever was first.
  • the final grading Cumulative 5 day response, is the sum total of grade scores for 20 assessments per panellist averaged over the scores from all panellists. Thus, theoretically, the average score could range from 0 to 30; the lower score indicating absolutely no skin irritation while the 30 score being the most severe. The following results were obtained: -
  • compositions according to the invention are significantly milder than the comparative containing no C 8 fatty acid soap and greater than 3 wt% C 12 fatty acid soap.
  • the results also show the addition of a small amount (1%) of C 12 fatty acid soap does not have an adverse effect on the product harshness.
