It typically has a particle size of 1 to 200 microns (e.g., 1 to 150 microns and 5 to 120 microns). In the aggregate, the polymer combination theoretical charge-to-weight ratio can be 0 to +0.2 (preferably 0 to +0.1 more preferably +0.01 to +0.1 and even more preferably, 0 to +0.02).
The polymer combination theoretical charge-to-weight ratio as used herein refers to the average theoretical charge per polymer molecular weight. For instance, a sodium alginate useful to prepare the aggregate is a copolymer of guluronic acid and mannuronic acid at a molar ratio of 1:1. It has a polymer combination theoretical charge-to-weight ratio of −0.00505 calculated as follows: /(average monomer unit molecular weight), where each of guluronic acid mannuronic acid has a negative charge, and their average monomer unit molecular weight is 198. As another example, 90% hydrolyzed polyvinylformamide useful to prepare the aggregate contains 90% vinyl amine units and 10% vinyl formamide. It has an polymer combination theoretical charge-to-weight ratio of +0.0197 calculated as follows: /(average monomer unit molecular weight), where vinyl amine has a charge of +1, vinyl formamide has a charge of 0, and the average monomer unit molecular weight is 0.9× molecular weight of vinyl amine+0.1× molecular weight of vinyl formamide=0.9×43+0.1×71=45.8. As still another example, a polymer mixture contains 0.01 grams of sodium alginate and 10 grams of 90% hydrolyzed polyvinyl formamide. The benefit particles each have a particle size of 0.1 to 50 microns (e.g., 0.5 to 30 microns), and contain an active material and a polymeric material.
CHIMEX CURCUMA SKIN
The active material is selected from the group consisting of fragrances, flavoring agents, fungicide, brighteners, antistatic agents, wrinkle control agents, fabric softener actives, hard surface cleaning actives, skin and/or hair conditioning agents, antimicrobial actives, UV protection agents, insect repellants, animal/vermin repellents, flame retardants, and a mixture thereof.īoth the binder and deposition polymers have a molecular weight of 5,000 to 10,000,000 Daltons (preferably, 10,000 to 1,000,000 Daltons and, more preferably, 100,000 to 750,000 Daltons).
