Definitions

  • This invention relates to the incorporation of a skin benefit agent in a fabric softening composition such that when fabrics treated with the fabric softening composition subsequently come into contact with the skin the fabrics deliver a benefit to the skin
  • Rinse added fabric softener compositions are well known. Typically such compositions contain a water insoluble amine salt and/or a quaternary ammonium fabric softening agent dispersed in water at a level of softening agent up to 7% by weight in which case the compositions are considered dilute, or at levels from 7% to 50% in which case the compositions are considered concentrates. Quaternary ammonium materials with long chain substituents have been used in fabric softening compositions for many years. Often they are used in conjunction with co-actives such as fatty acids or other relatively cheap materials which also provide softening benefits.
  • fabric softening compositions desirably have other benefits.
  • GB 1 601 359 (Procter and Gamble) describes the use of esters as an ingredient in a fabric softening composition which also comprises a cationic surfactant selected from various specified groups.
  • the ester is one of a number of nonionic fabric lubricants suggested.
  • GB 1 550 205 (Procter and Gamble) disclose formulations containing silicones, cationic compounds and glycerol monostearate for ease of ironing, and softening benefits may be obtained without the ester oil when other nonionic softeners are substituted for the glycerol monostearate.
  • Fabric softening compositions containing silicones are well known and are disclosed in GB 1 549 180 (Procter & Gamble) and EP 356 210 (Dow Corning).
  • EP 0 436 729 discloses an industrial process for applying microcapsules to fabric, which when contacted with the skin are physiologically active.
  • US 4110498 (Benjamin et al) discloses a fabric softening composition comprising a cationic fabric softener and a lanolin alcohol based fabric softener.
  • the present invention provides the use of a skin benefit agent as an ingredient in a fabric softening composition to enable the fabric softening composition to render textile fabrics treated with the composition capable of delivering the skin benefit agent to the skin with which the fabrics come into contact.
  • the present invention also provides the use of a skin benefit agent in a fabric softening composition to impart sensory and/or cosmetic benefits to the skin when fabrics treated with the composition come into contact with the skin.
  • the skin benefit agents are preferably substantive to fabric.
  • a skin benefit agent is suitably any agent intended to be deposited onto the skin for the purpose of imparting sensory and/or cosmetic benefits thereto. It is preferred if the skin benefit agent changes the sensory perception of the skin.
  • suitable skin benefit agents include moisturisers, skin softeners, emollients and sunscreens.
  • the skin benefit agent used in accordance with the present invention may be a liquid or solid provided that it is compatible with other ingredients of the fabric softening composition.
  • Preferred skin benefit agents include:-
  • the skin benefit agents are perceived to condition the skin.
  • a particularly preferred skin benefit agent is a silicone.
  • the silicone is essentially a linear di(C 1 -C 5 )alkylpolysiloxane or (C 1 -C 5 )alkylarylpolysiloxane)
  • examples of such silicones include the polydimethylsiloxanes.
  • a second class of preferred skin benefit agents comprises are long chain hydrocarbons and esters as disclosed in EP 0 000 406 (Procter & Gamble).
  • the level of skin benefit agent is from 1 to 25 wt% of the total composition, more preferably from 1 to 10 wt%.
  • the fabric conditioning composition for use with this invention comprises a fabric softening material.
  • the fabric conditioning material is a quaternary ammonium softening material.
  • the fabric softening composition comprises a water insoluble cationic softening material which is a compound having two C 12-28 alkyl or alkenyl groups connected to the N atom via one or more ester links.
  • a preferred type of ester-linked quaternary ammonium fabric softening material for use in the compositions according to the invention can be represented by the formula: in which each R 4 group is independently selected from C 1-4 alkyl, hydroxyalkyl groups or C 2-4 alkenyl groups; and wherein each R 5 group is independently selected from C 8-28 alkyl or alkenyl groups; X - is any suitable anion and n is o or an integer from 1 to 5.
  • a further preferred cationic softener is represented by the formula: wherein each R 6 group is independently selected from C 1-4 alkyl, hydroxyalkyl or C 2-4 alkenyl groups; and wherein each R 7 group is independently selected from C 8-28 alkyl or alkenyl groups; T is and n is o or an integer from 1 to 5 and X - is any suitable anion.
  • a further advantage of using ester linked quaternary ammonium materials with the above formula is that included within a composition according to the invention the compositions have excellent viscosities and are stable on storage.
  • the level of ester linked quaternary ammonium compounds is at least 1% by weight of the composition, more preferably at least 3% by weight of the composition; especially interesting are concentrated compositions which comprise at least 7% of ester-linked quaternary ammonium compound.
  • the level of ester-linked quaternary ammonium compounds preferably is from 1% to 80% by weight, more preferably from 4% to 32%, most preferably from 6% to 22%.
  • the ratio of fabric softening compound to skin benefit agent is from 5:1 to 1:5, more preferably from 4:1 to 2:3.
  • the softening composition may also comprise a nonionic stabilising agent selected from:
  • the nonionic stabilising agent is a linear C 8 to C 22 alcohol alkoxylated with 10 to 20 moles of alkylene oxide.
  • the nonionic stabiliser has an HLB value of from 10 to 20, more preferably from 12 to 20.
  • the level of nonionic stabiliser is within the range from 0 to 10% by weight, more preferably from 0 to 5% by weight, most preferably from 0 to 4% by weight.
  • the mole ratio of the quaternary ammonium compound to the nonionic stabilising agent is within the range from 40:1 to about 1:1, preferably within the range from 18:1 to about 3:1.
  • compositions of the invention are liquids comprising an aqueous base.
  • the composition can also contain a co-active, for example, a C 8 - C 24 alkyl or alkenyl monocarboxylic acid or polymer thereof.
  • a co-active for example, a C 8 - C 24 alkyl or alkenyl monocarboxylic acid or polymer thereof.
  • saturated fatty acid are used, in particular, hardened tallow (C 16 -C 18 ) fatty acids.
  • the fatty acid is non-saponified, for example free oleic acid, lauric acid or tallow fatty acid.
  • Lanolin or other nonionic fabric softening agents may also be used as co-actives.
  • the level of co-active material is preferably more than 0.1% by weight, more preferably more than 0.2% by weight.
  • concentrates comprising from 0.5 to 20% by weight of co-active, more preferably 1% to 10% by weight.
  • the weight ratio of quaternary ammonium/amine material to co-active material is preferably from 10:1 to 1:10.
  • composition can also contain one or more optional ingredients, selected from non-aqueous solvents, pH buffering agents, perfumes, perfume carriers, fluorescers, colourants, hydrotropes, antifoaming agents, soil release agents, enzymes, optical brightening agents, opacifiers, anti-shrinking agents, anti-spotting agents, germicides, fungicides, anti-oxidants, anti-corrosion agents, and antistatic agents.
  • optional ingredients selected from non-aqueous solvents, pH buffering agents, perfumes, perfume carriers, fluorescers, colourants, hydrotropes, antifoaming agents, soil release agents, enzymes, optical brightening agents, opacifiers, anti-shrinking agents, anti-spotting agents, germicides, fungicides, anti-oxidants, anti-corrosion agents, and antistatic agents.
  • Rinse conditioner formulations according to table 1 were prepared by melting the cationic compound in the silicone fluid with rapid stirring, demineralised water at 70°C. Stirring was continued for 10-15 minutes prior to subjecting the mixture to high shear agitation using a Silverson homogeniser for 10-15 minutes.
  • Example A 1 2 HEQ 1 5 4 4 PDMS 5Pa.S (5000 cSt) 2 1 PDMS 30Pa.S (30,000 cSt) 2 1 Water and minors to 100
  • the treated terry towelling pieces were rubbed onto the front forearms of the assessor for one minute.
  • Three tape strip samples of the skin surface were taken and analysed for silicon by XRF spectrometry. Silicone levels were recorded in counts per second (CPS) from S XRF spectrometry of the tape strips. Each figure represents the mean of three independent tape strip values.
