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).
