The hand sanitizer may be a hand foam sanitizer or a hand gel sanitizer. Each of the hand sanitizers includes at least one stabilizing agent, at least one skin care agent, and a volume of disinfecting micelle capsules suspended therein. Each disinfecting capsule has a polymer shell which defines a hollow core. The polymer shell includes an antimicrobial material. The antimicrobial material may have a concentration of between 0.5 wt % and 95 wt % of the polymer shell. In order to make the hand foam sanitizer, at least one foaming agent is added to produce a foam by air foaming. The hollow core of each disinfecting capsule may be filled with a material, such as at least one disinfectant, at least one fragrance, at least one supplemental skin care agent, or combinations thereof.

Hand sanitizer and method of making the same

Methods and formulations for antimicrobial and anti-biofouling coating comprising: a hollow round colloidal structure, comprising: an active polymer shell; and an active or inert core; wherein the active polymer shell comprises one and more polymers with antimicrobial and anti-biofouling activities selected from the group consisting of polyethylenimine (PEI), functionalized chitosan (CHI), polyquaternium, poly(diallyldimethylammonium chloride) (PDDA) and polyhexamethylene biguanide (PHMD); wherein the active or inert core contains one and more disinfectants, biocides, fragrances or inert solvent; and wherein the hollow round colloidal structure is stable for at least 3 months.
