Methods for making encapsulate-containing product compositions
Methods relating to making product compositions that include encapsulates, borate compounds, and a cationic polysaccharide, where the encapsulates include polyvinyl alcohol polymer. Compositions made from such methods. Encapsulate slurries.
1. A method of making a detergent composition, the method comprising the steps of:
a. providing a first composition comprising encapsulates and a second composition,
wherein the encapsulates comprise a polyvinyl alcohol polymer;
wherein the first composition is an encapsulate slurry comprising from about 10% to about 60%, by weight of the first composition, of encapsulates and from about 0.1% to about 10% by weight of the first composition, of a cationic polysaccharide,
wherein the encapsulates comprise a core and a shell at least partially surrounding the core, wherein the core comprises a benefit agent, and wherein the shell comprises at least a portion of the polyvinyl alcohol polymer;
wherein the second composition comprises a borate compound; and
b. combining the first composition and the second composition to form a product composition.
2. A method according to claim 1 , wherein the benefit agent of the core comprises perfume raw materials.
3. A method according to claim 1 , wherein the shell comprises a shell material selected from the group consisting of polyethylenes; polyamides; polystyrenes; polyisoprenes; polycarbonates; polyesters; polyacrylates; acrylics; aminoplasts; polyolefins; polysaccharides; gelatin; shellac; epoxy resins; vinyl polymers; water insoluble inorganics; silicone; and mixtures thereof.
4. A method according to claim 1 , wherein the shell comprises a shell material 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.
5. A method according to claim 1 , wherein the shell comprises a polyacrylate.
6. A method according to claim 1 , wherein the borate compound is selected from the group consisting of boric acid, boric acid derivatives, and combinations thereof.
7. A method according to claim 1 , wherein the borate compound is present in the product composition at a level of about 0.1 wt % to about 10 wt %, by weight of the product composition.
8. A method according to claim 1 , wherein the second composition further comprises a cationic polysaccharide.
9. A method according to claim 1 , wherein the cationic polysaccharide is a cationic cellulose derivative.
10. A method according to claim 1 , wherein the cationic cellulose derivative is selected from the group consisting of cationic hydroxyethylcellulose, cationic hydroxypropylcellulose, and mixtures thereof.
11. A method according to claim 10 , wherein the cationic hydroxyethylcellulose comprises hydroxyethyl cellulose derivatized with trimethyl ammonium substituted epoxide.
12. A method according to claim 1 , wherein the cationic polysaccharide is characterized by a weight average molecular weight of from greater than 100,000 to 2,000,000.
13. A method according to claim 1 , wherein the product composition comprises from about 0.01 wt % to about 5 wt % of the encapsulates.
14. A method according to claim 1 , wherein the product composition comprises from about 5 wt % to about 60 wt % of surfactant.
15. A method according to claim 1 , wherein the product composition comprises no more than 5 encapsulates per gram of product composition, as determined by the Method for Determining Number of Particles (“AN212 Method”).
16. A method according to claim 1 , wherein either the first composition or the second composition is a base detergent comprising from about 5 wt % to about 75 wt % of a surfactant system.
