The present invention relates to compositions comprising a structured benefit agent pre-mix or delivery vehicle comprising benefit agent structured with crystalline materials, as defined, which when separately prepared and combined after preparation, provides enhanced delivery of benefit agent to a carrying composition into which the premix is added.

Personal product compositions comprising structured benefit agent premix or delivery vehicle

The invention provides personal wash compositions which deposit high levels of sunscreen while maintaining good lather. Enhanced deposition, from bar or liquid, is based on specific sunscreens used, particularly on their solubility.

Personal wash sunscreen compositions which deposit and lather well

Novel compositions are prepared in a non-molten process. In particular, compositions comprise optional fillers with both soap and high levels of synthetic surfactants. When high levels of soap and surfactant are normally used in such process, there is a significant 'grittiness' problem. Pre-processing the surfactant containing chip (e.g., 'DEFI' chip) has been unexpectedly found to remedy this problem.

A solid detergent composition useful for machine dishwashing is described. The product contains a first layer having an oxygen bleach system, a buffering system, a builder, and an enzyme. The first layer dissolves to deliver a pH of about 8.5 to about 11 in the wash water. A second layer includes an effective amount of an acidity agent and a continuous medium having a melting point in the range of from about 35.degree. C. to about 50.degree. C. The material may be a paraffin wax, a natural wax, a polyvinyl ether, fatty acids and mixtures thereof. The second layer dissolves in wash water to deliver a pH of from about 6.5 to about 9. The release order of the functional ingredients allows for a high level of peracid species generation in the initial wash stages followed by optimum bleaching throughout the wash.

The invention pertains to granules which incorporate citric acid monohydrate as an exotherm control agent within a peracid containing core. The granules have improved dissolution rates of the peracid in a dishwashing cycle. Compositions containing the granules are also described.

A solid detergent composition useful for machine dishwashing is described. The product contains a first layer having a buffering system, a builder and an enzyme. The first layer dissolves to deliver a pH of about 9.0 to about 11 in the wash water. A second layer includes a peracid and an acidity agent in a continuous medium having a melting point in the range of from about 35.degree. C. to about 50.degree. C. The material may be a paraffin wax, a natural wax, a polyvinyl ether, fatty acids and mixtures thereof. The second layer dissolves in wash water to deliver a pH of from about 6.5 to about 9. The release order of the functional ingredients allows for a optimum bleaching of stains as well as removal of soil.

Machine dishwashing tablets containing a peracid

A solid detergent composition and a method of using the composition in a machine dishwasher is described. The product contains a first layer having an oxygen bleaching system, a buffering system of a builder, and an enzyme. The first layer dissolves to deliver a pH of about 8.5 to about 11 in the wash water. A second layer includes an effective amount of an acidity agent selected from an inorganic acid, an organic acid and mixtures thereof, a continuous medium having a melting point in the range of from about 55.degree. C. to about 70.degree. C. and an anti-scaling agent. The second layer dissolves in wash water to deliver a pH of from about 6.5 to about 9.

A polyvinyl ether and paraffin wax blend is described which is useful as a coating for encapsulates which are stable in an alkaline environment and which exhibit a volume % compressibility of 20.degree. or less at 30.degree. C. The polyvinyl ether material has a formula [C.sub.x H.sub.2x O].sub.y.

Polyvinyl ether encapsulated particles

The present invention relates to an improved curing or hardening process for the continuous production of capsules containing a sensitive material. The process allows capsules to be formed continuously without aggregating. The process is also a contained system so that exposure to possibly harmful aerosols is avoided.

Process for encapsulating sensitive materials

Wax-encapsulated particles having a core particle or an aggregate of core particles selected from the group of an organic peroxy acid, a diacyl peroxide, an inorganic peroxygen compound, a bleach catalyst, a peroxygen bleach precursor and mixtures thereof together with 0.01% to about 5% by weight of a surfactant. The resulting particles exhibit release rates from their capsules and dissolution rates comparable to uncoated core materials.

Encapsulates containing surfactant for improved release and dissolution

A polyvinyl ether and paraffin wax blend is described which is useful as a coating for encapsulates which are stable in an alkaline environment and which exhibit a volume % compressibility of 20 or less at 30.degree. C. The polyvinyl ether material has a molecular formula [C.sub.x H.sub.2x O].sub.y.

Liquid cleaning composition containing polyvinyl ether encapsulated

Solid core particles encapsulated in a single coat of paraffin wax, the wax having a melting point of about 40.degree. to about 50.degree. C. and a solids content of from 100 to about 35% at 40.degree. C. and from 0 to about 15% at 50.degree. C. The paraffin coat may comprise 20 to 90% by weight of the particle and may be from 100 to 1,500 microns thick. The coat prolongs the time in which particles encapsulated therewith may remain active in aqueous environments. The encapsulated particle is made by spraying molten wax onto the particles in a fluidized bed. Liquid or powder cleaning compositions, particularly automatic dishwashing liquid detergents, may incorporate 0.01 to 20% by weight of the composition of the coated wax-encapsulated particles.

Wax-encapsulated particles

Method for wax encapsulating particles

A stable liquid automatic dishwashing compositions as well as a process for its preparation is disclosed. The composition is an aqueous thixotropic fluid possessing a yield point. The composition may include swellable clays, synthetic polymers, a specified amount of multivalent cations, builder salts, an alkaline source, a hypochlorite source, nonionic or anionic surfactants, and defoamers. The system containing clay, polymer, and ions thickens the composition to provide structure to suspend finely divided solid components, while maintaining good salt tolerance and stability against hypochlorite.
