Definitions
- the present invention relates to laundry detergent compositions comprising volatile benefit agent in encapsulated and non-encapsulated forms, encapsulated phase change material and an anionic and a non-ionic surfactant.
- Fragrances are a valuable and ubiquitously employed benefit agent in home and personal care applications.
- the use of perfumes in laundering signals to the consumer that the washing process has been achieved to an acceptable level.
- Encapsulated perfume technologies are known for use in laundry products. Such technologies provide enhanced fragrance delivery over conventional free perfume oil by overcoming the issue of perfume loss during the drying process by protecting the perfume in the capsule. Encapsulation also ensures that perfume is released at the optimal time to enable the provision of a perceivable benefit to the wearer of laundered garments. Examples of the mode of action of encapsulates include: shear sensitive action, where the perfume core is released in response to mechanical rupture of the encapsulate, and diffusive action, wherein perfume is released by diffusion through the outer wall of the encapsulate.
- encaps are capable of both release mechanisms.
- One type of capsule that has been used in laundry compositions has a melamine formaldehyde shell and a perfume core. Release of perfume from melamine formaldehyde capsules is friction based, the benefit becoming apparent after a rubbing process is applied to the treated fabric. This benefit is provided by a boost in perfume intensity during wear.
- WO 2010/060677 (Henkel AG & Co KGAA) discloses scented washing or cleaning agents, comprising anionic and non-ionic surfactants, encapsulated scents and non-encapsulated scents.
- a preferred embodiment further comprises an encapsulated active comprising urea or other skin conditioning agents.
- the present invention provides a laundry detergent composition, which comprises:
- phase change active having a phase change temperature of from 24 to 39 ° C;
- a process for treating fabric comprising the step of treating a fabric article with a composition as defined by the first aspect.
- the encapsulated volatile benefit agent comprises a capsule and a volatile benefit agent.
- the capsule comprises a shell and a core.
- the capsule comprising the volatile benefit agent comprises a shell that is comprised of materials including but not limited to polyurethane, polyamide, polyolefin, polysaccaharide, protein, silicone, lipid, modified cellulose, gums, polyacrylate, polyphosphate, polystyrene, polyesters or combinations of these materials.
- Other encapsulating material which may be used effectively in the present invention, such as polymethylmethacrylate.
- Preferred encapsulating polymers include those formed from melamine formaldehyde or urea
- the shell comprises melamine formaldehyde.
- microcapsules made via the simple or complex coacervation of gelatin are suitable for use in compositions of the invention.
- Encapsulation can provide pore vacancies or interstitial openings depending on the encapsulation techniques employed.
- Fragrance capsules known in the art and suitable for use in the present invention comprise a wall or shell comprising a three-dimensional cross-linked network of an aminoplast resin, more specifically a substituted or un-substituted acrylic acid polymer or co-polymer cross-linked with a urea-formaldehyde pre-condensate or a melamine-formaldehyde pre-condensate.
- the capsules for use in the invention may further comprise a carrier oil in the core.
- the carrier oils are hydrophobic materials that are miscible in the volatile benefit agent materials used in the present invention. Suitable oils are those having reasonable affinity for the benefit agent.
- suitable materials include, but are not limited to triglyceride oil, mono and diglycerides, mineral oil, silicone oil, diethyl phthalate, polyalpha olefins, castor oil and isopropyl myristate.
- the oil is a triglyceride oil, most preferably a capric/caprylic triglyceride oil.
- the capsules may be used in the form of a slurry, which preferably comprises about 40% solids.
- Particle size and average diameter of the capsules can vary from about 10 nanometers to about 1000 microns, preferably from about 50 nanometers to about 100 microns, more preferably from about 2 to about 40 microns, even more preferably from about 4 to 15 microns. A particularly preferred range is from about 5 to 10 microns, for example 6 to 7 microns.
- the capsule distribution can be narrow, broad or multimodal. Multimodal distributions may be composed of different types of capsule chemistries.
- the shell may further comprise a deposition aid, which is preferably covalently attached.
- a preferred deposition aid is a polysaccharide.
- the polysaccharide preferably has a B-1 ,4-linked backbone.
- the polysaccharide is a cellulose, a cellulose derivative, or another ⁇ - 1 ,4-linked polysaccharide having an affinity for cellulose, such as polymannan, polyglucan, polyglucomannan, polyxyloglucan and polygalactomannan or a mixture thereof. More preferably, the polysaccharide is selected from the group consisting of polyxyloglucan and polygalactomannan.
- Highly preferred polysaccharides are selected from locust bean gum, tamarind gum, xyloglucan, non-ionic guar gum, cationic starch and mixtures thereof.
- the deposition aid is locust bean gum.
- the polysaccharide backbone has only ⁇ -1 ,4 linkages.
- the polysaccharide has linkages in addition to the ⁇ -1 ,4 linkages, such as ⁇ -1 ,3 linkages.
- linkages in addition to the ⁇ -1 ,4 linkages, such as ⁇ -1 ,3 linkages.
- polysaccharide backbones which include some material which is not a saccharide ring are also within the ambit of the present invention (whether terminal or within the
- the polysaccharide may be straight or branched. Many naturally occurring polysaccharides have at least some degree of branching, or at any rate at least some saccharide rings are in the form of pendant side groups (which are therefore not in themselves counted in determining the degree of substitution) on a main polysaccharide backbone.
- the polysaccharide is present at levels of between 0.1 % to 10% w/w by weight of the total amount of the particle.
- the deposition aid which is preferably a polysaccharide, is attached to the particle by means of a covalent bond, entanglement or strong adsorption, preferably by a covalent bond or entanglement and most preferably by means of a covalent bond.
- entanglement as used herein is meant that the deposition aid is adsorbed onto the particle as the polymerisation proceeds and the particle grows in size, part of the adsorbed deposition aid becomes buried within the interior of the particle.
- part of the deposition aid is entrapped and bound in the polymer matrix of the particle, whilst the remainder is free to extend into the aqueous phase.
- strong adsorption as used herein is meant strong adsorption of the deposition aid to the surface of the particle; such adsorption can, for example, occur due to hydrogen bonding, Van Der Waals or electrostatic attraction between the deposition aid and the particle.
- the deposition aid is thus mainly attached to the particle surface and is not, to any significant extent, distributed throughout the internal bulk of the particle.
- This is distinct from graft copolymers in which e.g. a polysaccharide may be grafted along the length of a polymer chain.
- a particle which is formed from a graft copolymer would, therefore, contain polysaccharide throughout the internal bulk of the particle as well as on the particle surface and the present invention is not intended to cover such a particle.
- the particle which is produced when using a polysaccharide as the deposition aid according to the process of the invention can be thought of as a "hairy particle", which is different from a graft copolymer.
- This feature of the invention provides significant cost reduction opportunities for the manufacturer as much less deposition aid is required to achieve the same level of activity as systems which utilise polysaccharide copolymers.

- the polyoxyalkyleneoxy may be a mixture of different oxyalkyleneoxy. Different polyoxyalkyleneoxy types may present in the polymer, (s and w are intergers).
- the phenyl dicarboxylate is a 1 ,4-phenyl dicarboxylate.
- the phenyl dicarboxylate is of the form: -OC(O)C 6 H 4 C(O)O-.

Given that this measure is a ratio of the equilibrium concentration of a PRM in a non-polar solvent (octanol) with its concentration in a polar solvent (water), ClogP is also a measure of the hydrophobicity of a material-the higher the ClogP value, the more
