Benefit agent containing delivery particles that can be supplied as slurries, compositions comprising such particles, and processes for making and using such particles and compositions.

Benefit agent containing delivery particle

The present application relates to encapsulated benefit agents, compositions comprising such encapsulated benefit agents and processes for making and using compositions comprising such encapsulated benefit agents. Such encapsulated benefit agents eliminate or minimize one or more of the drawbacks of current encapsulated benefit agents and thus provide formulators with additional perfume delivery opportunities.

Delivery particle

An aqueous slurry composition containing microcapsules dispersed in an aqueous medium. The microcapsules contain an ionic acrylate copolymer shell encapsulating an oily medium. Upon drying, the microcapsules release the oily medium. The slurry is useful in delivering a variety of water-insoluble substances via an aqueous medium including cosmetic or agricultural agents.

Aqueous microcapsule slurry

Slurries that include benefit agent containing delivery particles, compositions that include such particles, and processes for making and using the particles and compositions.

Benefit agent containing delivery particle slurries

The invention describes a core shell microcapsule wherein the capsule shell is hydrolysable. The capsule is made from a water phase with initiator and emulsifier, and from one or more oil phases having a first multifunctional (meth)acrylate monomer having greater than one ester group on average in the monomer and having a hydrophilicity index of less than 20; a second multifunctional (meth)acrylate monomer, the second multifunctional (meth)acrylate comprising a hydrophilic multifunctional polar monomer having a hydrophilicity index of at least 20 and said second multifunctional polar monomer comprising 50% or less of the capsule shell along with an acidic (meth)acrylate monomer or at least one oil soluble or dispersible simple acid, the acidic (meth)acrylate monomer having one or more groups which are selected from carboxy and sulfonic groups, and optionally from 0 to 50% by weight of the shell comprises in addition an aliphatic polyester comprising an oligomer, polymer or co-polymer of one or more of lactic acid, caprolactone, or glycolic acid, the aliphatic polyester having two or more of acrylate or methacrylate groups.

Encapsulation

A method of forming microcapsules having improved physical properties and release control as well as the microcapsules formed by the process wherein the capsule wall is formed by the concurrent polymerization of monomers, oligomer and/or prepolymers on the inside of the capsule wall and different monomers, oligomers and/or prepolymers on the exterior of the capsule wall as it forms.

Controlled release microcapsules

The present invention relates to compositions of benefit agent containing delivery particles and slurries comprising benefit agent containing delivery particles, compositions comprising the particles, and processes for making and using the aforementioned particles and compositions. Such slurries and benefit agent containing delivery particles are stable and when employed in compositions, for example, cleaning or fabric care compositions, the particles in such slurries increase the efficiency of benefit agent delivery, thereby allowing reduced amounts of benefit agents to be employed. In addition to allowing the amount of benefit agent to be reduced, such particles allow a broad range of benefit agents to be employed. The compositions can comprise particles, cakes, powders, particulates, aggregates, aggregate clusters and slurries comprising the benefit agent containing delivery particles.

Benefit agent containing delivery particle composition

An improved process of making a benefit agent delivery particle and consumer products incorporating such particles are disclosed. The process comprises the steps of providing a first composition of water phase 1, water phase 2 and water phase 3. Water phase 1 comprises water and an initiator; water phase 2 comprises water, a water-soluble or dispersible amine(meth)acrylate or hydroxyl(meth)acrylate and a multifunctional (meth)acrylate. Water phase 3 comprises water, and carboxyalkyl(meth)acrylate and a base or quaternary ammonium acrylate. The first two water phases are combined to prereact the hydroxy- or amine(meth)acrylate and the multifunctional (meth)acrylate to form a multifunctional hydroxyl-amine(meth)acrylate pre-polymer. The pre-polymer is combined with water phase 3; then an emulsion is formed by emulsifying under high shear agitation a second composition into said first composition; said second composition comprising an oil phase comprising an isocyanate and a benefit agent core material thereby forming a wall surrounding the benefit agent core material.
