The disclosed technology relates to a formulation for a unit does cleansing product without the use of a film package, which contains a basic cleansing composition and a structurant comprising C6-C30 fatty acid or mixtures thereof and at least one water soluble polymer or water dispersible polymer.

A microcapsule composition containing microcapsules is provided as is a method for making the microcapsule composition and using the microcapsule composition in consumer products.

The present invention relates to a new process for the preparation of microcapsules. Microcapsules obtainable by said process are also an object of the invention. Perfuming compositions and consumer products comprising said capsules, in particular perfumed consumer products in the form of home care or personal care products, are also part of the invention.

A fabric care composition that includes quaternary ammonium ester material and a population of delivery particles, where the quaternary ammonium ester material includes triester quaternary ammonium material (“triester quats”), and where the shells of the delivery particles include a polymeric material that is the reaction product of a polyisocyanate and chitosan, preferably hydrolyzed chitosan. A method of treating a fabric with the composition.

A method of treating a fabric, where the method includes the steps of contacting a fabric with a treatment composition, where the treatment composition comprises a population of delivery particles having a shell that includes a polymeric material that is the reaction product of a polyisocyanate and chitosan, and exposing the delivery particles that are on the surface of the fabric to ultraviolet (UV) light. A consumer product that includes such treatment compositions in containers that block or absorb ultraviolet light.

A liquid detergent composition may have a continuous liquid phase and solid particles dispersed in the continuous phase. The continuous phase may be transparent or translucent. The solid particles may be made of a polymeric matrix material, have a diameter ranging from about 0.8 to about 8 mm, and may include a plurality of microcapsules. The plurality of microcapsules may be dispersed in the polymeric matrix material. The microcapsules may have a diameter ranging from about 4 to about 70 70 μm. Use of and methods of use of such a liquid composition are also described.

The invention provides a method for the cleaning of a soiled substrate, the method comprising treating the substrate with a solid particulate cleaning material and wash water, the treatment being carried out in an apparatus comprising a drum comprising perforated side walls and having a capacity of between 5 and 50 liters for each kg of fabric in the washload, wherein said solid particulate cleaning material comprises a multiplicity of polymeric particles at a particle to fabric addition level of 0.1:1-10:1 by mass, each particle being substantially cylindrical or spherical in shape and having an average density in the range of 0.5-2.5 g/cm.sup.3 and an average volume in the range of 5-275 mm.sup.3, and wherein said drum comprising perforated side walls is rotated at a speed which generates G forces in the range of from 0.05 to 900 G. The polymeric particles may comprise foamed or unfoamed polymeric materials which may comprise either linear or crosslinked polymers. Preferably, at least one detergent is employed in the cleaning process. The invention provides optimum cleaning performance as a result of improved mechanical interaction between substrate and cleaning media and is preferably used for the cleaning of textile fabrics. The method allows for significant reductions in the consumption of detergents, water and energy when compared with the conventional wet cleaning of textile fabrics, and also facilitates reduced washing-related textile fabric damage. The invention also envisages a cleaning composition comprising a solid particulate cleaning composition and at least one additional cleaning agent. In particular embodiments of the invention, the solid particulate cleaning material is separated and recovered and then re-used in subsequent cleaning processes. Typically, the solid particulate cleaning material is itself cleaned intermittently in order to maintain its efficacy.

A microcapsule composition containing microcapsules coated with a deposition protein, e.g., a protein-silanol copolymer, a protein-silane copolymer, a protein-siloxane copolymer, or a cationically modified protein, is provided as is a method for making the microcapsule composition and using the microcapsule composition in consumer products, in particular rinse-off consumer product.
