    Abstract: Disclosed herein are methods that include contacting a skin surface with a first liquid composition; and then contacting in the skin surface with a cationic coated article loaded with a second liquid composition, while at least some portion of the first liquid composition remains on the skin surface, wherein one or both of the first liquid composition or the second liquid composition includes acrylate copolymer particles dispersed therein, the acrylate copolymer particles including the reaction product of a reaction mixture, the reaction mixture including monomers, the monomers including from about 5 wt % to about 50 wt % of at least one high Tg monomer where the wt % of the high Tg monomer is with respect to the total weight of the monomers in the reaction mixture; and from about 20 wt % to about 80 wt % of at least one low Tg monomer where the wt % of the low Tg monomer is with respect to the total weight of the monomers in the reaction mixture, wherein the particles have a number average diameter of at least about 100 nm and wherein at least one and only one of the first or the second composition comprises greater than or equal to 60 wt % of at least one alcohol.

    Abstract: A copolymer composition that includes a silicone copolymer, methods of making the composition, and articles that include the composition, wherein the copolymer composition includes a silicone copolymer having a backbone composition that includes: silicone segments in an amount of 5 wt-% to 40 wt-%, based on the total weight of the silicone copolymer; hydrophilic segments in an amount of 40 wt-% to 75 wt-%, based on the total weight of the silicone copolymer; and reinforcing segments in an amount of 5 wt-% to 30 wt-%, based on the total weight of the silicone copolymer, wherein the reinforcing segments are derived from the reaction of one or more chain extenders with one or more multi-functional isocyanates, multi-functional carboxylic acids, multi-functional anhydrides, multi-functional esters, and/or multi-functional acid halides; wherein the silicone segments, hydrophilic segments, and reinforcing segments are connected through urea, urethane, amide, and/or oxamide linkages; wherein the hydrophilic segments and the reinforcing segments are present in a weight ratio of 1.8:1 to 8:1; and the hydrophilic segments and the silicone segments are present in a weight ratio of 1.3:1 to 4.5:1.
