Compositions with perfume encapsulates
A composition that comprises encapsulates, the encapsulates having a core that includes perfume characterized by an acid value of greater than 5.0 mg KOH/g of perfume, the encapsulates also including a shell that includes a (meth)acrylate material. Methods of making and using such compositions.
1. A composition comprising:
encapsulates, the encapsulates comprising a core and a shell surrounding the core, the core comprising a perfume mixture, wherein the perfume mixture comprises a mixture of perfume raw materials, the mixture of perfume raw materials being characterized by an acid value of the perfume mixture of greater than 5.0 mg KOH/g of perfume immediately before encapsulation, wherein the perfume mixture comprises from about 30% to about 75% by weight of the total perfume in the core immediately after encapsulate formation, of perfume raw materials that comprise aldehyde moieties, acetal moieties, ester moieties, or mixtures thereof and the shell comprising a polymeric material, the polymeric material comprising a (meth)acrylate material derived from hexafunctional acrylate.
2. A composition according to claim 1 , wherein
the perfume is characterized by an acid value of greater than about 5.25 mg/KOH immediately before encapsulation.
3. A composition according to claim 2 , wherein
the perfume comprises from about 30% to about 75% by weight of the total perfume in the core immediately after encapsulate formation, of aldehyde compounds, ester compounds, or mixtures thereof.
4. A composition according to claim 3 , wherein
the perfume comprises a material selected from the group consisting of: aliphatic aldehydes and/or their acetals; cycloaliphatic aldehydes; aromatic and/or araliphatic aldehydes; aliphatic, aromatic, or araliphatic esters; lactones; or mixtures thereof.
5. A composition according to claim 4 , wherein
the core further comprises a partitioning modifier selected from the group consisting of vegetable oil, modified vegetable oil, mono-, di-, and tri-esters of C4-C24 fatty acids, isopropyl myristate, dodecanophenone, lauryl laurate, methyl behenate, methyl laurate, methyl palmitate, methyl stearate, and mixtures thereof.
6. A composition according to claim 1 , wherein
the polymeric material of the shell is formed, at least in part, by a radical polymerization process.
7. A composition according to claim 1 , wherein
the (meth)acrylate material is selected from the group consisting of a polyacrylate, a polyethylene glycol acrylate, a polyurethane acrylate, an epoxy acrylate, a polymethacrylate, a polyethylene glycol methacrylate, a polyurethane methacrylate, an epoxy methacrylate, and mixtures thereof.
8. A composition according to claim 1 , wherein
the encapsulates are characterized by a volume weighted median diameter of about 10 to about 100 microns.
9. A composition according to claim 1 , including
in addition an adjunct material, wherein the adjunct comprises a material selected from the group consisting of surfactants, conditioning actives, deposition aids, rheology modifiers or structurants, bleach systems, stabilizers, builders, chelating agents, dye transfer inhibiting agents, dispersants, enzymes, and enzyme stabilizers, catalytic metal complexes, polymeric dispersing agents, clay and soil removal/anti-redeposition agents, brighteners, suds suppressors, silicones, hueing agents, aesthetic dyes, additional perfumes and perfume delivery systems, structure elasticizing agents, carriers, hydrotropes, processing aids, anti-agglomeration agents, coatings, formaldehyde scavengers, pigments, and mixtures thereof, the composition comprising other than a consumer product.
10. A composition according to claim 9 , wherein
the adjunct comprises a surfactant, the surfactant being selected from an anionic surfactant, nonionic surfactant, zwitterionic surfactant, cationic surfactant, amphoteric surfactant, and combinations thereof, the composition comprising other than a consumer product.
11. A composition according to claim 1 , wherein
the composition is in the form of a liquid composition, a granular composition, a dissolvable sheet, a pastille or bead, a fibrous article, a tablet, a bar, a flake or a dryer sheet, the composition comprising other than a consumer product.
12. A composition according to claim 1 , wherein
the composition is encapsulated in water-soluble film, the composition comprising other than a consumer product.
