Abstract: The invention provides a benefit agent delivery particle having an average diameter of less than 50 micron comprising; at least one shell formed by a step-growth polymerisation reaction, preferably involving an isocyanate monomer, more preferably a urethane and/or a urea, interior said shell, at least one region formed by chain-growth polymerisation reaction (preferably a free-radical polymerisation) which does not involve an isocyanate, c) optionally, a benefit agent interior to said shell, and/or a deposition aid exterior to said shell. The invention further provides a process for the preparation of such particles wherein the shell is formed prior to the chain-growth polymerisation of the at least one region interior of the shell, preferably be forming the shell at a temperature at which the chain-growth reaction is inhibited.

Abstract: The invention relates to a process for the manufacture of core-shell perfume particles by emulsion polymerisation and to the products obtainable by such a process. The core of the particles comprises a perfume and the shell (which preferably comprises an aminoplast polymer) also comprises a non-ionic deposition aid (such as locust bean gum) which is substantive to textiles. The process of the invention is characterised in that, during the emulsion polymerisation step, the solids content of the polymerisation mixture does not fall below 25% wt. The particles obtained by the process are suitable for inclusion in laundry products and show significantly improved deposition and retention onto fabrics being laundered as compared with particles formed at lower solids levels.

Abstract: A fabric conditioning kit comprises a water-soluble package for containing a liquid rinse conditioning composition and an activator provided separately from the water-soluble package and comprising an active ingredient which causes and/or accelerates the disintegration of the water-soluble polymeric film. The package is placed into the washing machine drum at the beginning of the wash cycle and the activator is placed in the rinse compartment of the dispensing drawer.

Abstract: A water soluble package comprises a substantially non-aqueous liquid rinse conditioning composition therein, wherein the water soluble package comprises a polymeric film. A process for conditioning fabrics comprises the step of adding to the rinse cycle of a washing operation the water soluble package and rinse conditioning composition therein, allowing or causing the package to break so as to release the contents therefrom and contacting the composition with fabric being laundered. The package is either disposed in the drum at the beginning of the wash cycle, remains intact through the wash cycle and disperses and/or dissolves at the beginning of or during the rinse cycle or is disposed in the rinse compartment of the dispenser drawer or in the drum between the wash and rinse cycles and disperses and/or dissolves immediately.

Abstract: A water soluble package and a substantially non-aqueous liquid rinse conditioning composition therein, wherein the water soluble package comprises a polymeric film provided one or more modifying protective functional groups. The modifying protective functional groups are arranged to protect the active functional groups that may be present in the film so as to prevent decomposition of the film during the wash cycle but to allow or accelerate decomposition of the film during the rinse cycle.

Abstract: An aqueous fabric conditioning composition comprises a cationic surfactant, an oil, a solvent and is in the form of a water-in-oil micro-emulsion. The cationic surfactant comprises either (a) quaternary ammonium compounds having at least one ester group and being formed from a parent fatty acid having a degree of unsaturation represented by an iodine value of from 20 to 140 or (b) quaternary ammonium compounds having two C8-C28 alkyl or alkenyl chains directly attached to the nitrogen and being formed from a parent fatty acid having a degree of unsaturation represented by an iodine value of from 0 to 20 or (c) mixtures of (a) and (b). The invention also relates to a process for treating fabrics and a method for preparing a fabric treatment composition.

Abstract: A fabric conditioner concentrate is produced comprising a liquid or soft solid derivative of cyclic polyol or a reduced saccharide resulting from 35 to 100% of the hydroxyl groups in the cyclic polyol or reduced saccharide being esterified or etherified, the derivative having at least two or more ether groups independently attached to a C8-C22 alkyl or alkenyl chain or mixtures thereof, containing at least 35% tri- or higher esters, an emulsifying agent, a deposition aid and less than 30% by weight water. The nonionic fabric softening component dissolves the deposition aid, which, if it is a cationic deposition aid, can also act as an emulsifying agent, allowing the composition to emulsify easily on mixing with water. Fabric conditioning concentrates according to the present invention maybe in the form of clear isotropic compositions or clear water-in-oil micro-emulsions. The deposition aid allows the nonionic fabric softening component to deposit onto fabric from the emulsion during a rinse step.

Preferably the compound has two or more ester and/or ether groups. A fabric softening composition comprises from 1 to 80 wt % of the softening compound, based on the total weight of the composition. A method for forming such compounds comprises reacting a cyclic polyol or a reduced saccharide with a fatty acid and a halogen alkyl acid chloride to form an, at least partly, esterified cyclic polyol or reduced saccharide and then quaternising the esterified compound so as to form a CPED or RSED comprising a quaternary ammonium group.
