Abstract
A nail enamel based on a solvent mixture of nitrocellulose, and plasticizer(s) is made faster drying by incorporating a particular class of vinyl-silicone copolymers. Trapping of bubbles in the dried enamel is avoided by incorporating a dimethicone anti-foaming agent.
Claims7
A fast drying nail enamel composition comprising
- (A) a base mixture comprising (1) solvent, (2) plasticizer and (3) nitrocellulose;
- (B) a fast dry improving effective amount of a vinyl-silicone copolymer of the formula ##STR4## wherein G.sub.5 represent monovalent moieties which can independently be the same or different selected from the group consisting of alkyl, aryl, alkaryl, alkoxy, alkylamino, fluoroalkyl, hydrogen and -ZSA;
- A represents a vinyl polymeric segment consisting essentially of polymerized free radically polymerizable vinyl monomer,
- Z is a divalent linking group selected from the group consisting of alkylene, alkarylene, arylene and alkoxyalkylene;
- G.sub.6 represents monovalent moieties which can independently be the same or different selected from the group consisting of alkyl, aryl, alkaryl, alkoxy, alkylamino, fluoroalkyl, hydrogen, and -ZSA;
- G.sub.2 comprises A;
- G.sub.4 comprises A;
- R.sub.1 represents monovalent moieties which can independently be the same or different and are selected from the group consisting of alkyl, aryl, alkaryl, alkoxy, alkylamino, fluoroalkyl, hydrogen, and hydroxyl;
- R.sub.2 can independently be the same or different and represents divalent linking groups selected from the group consisting of alkylene, alkarylene, arylene and alkoxyalkylene;
- R.sub.3 represents monovalent moieties which can independently be the same or different and are selected from the group consisting of alkyl, aryl, alkaryl, alkoxy, alkylamino, fluoroalkyl, hydrogen, and hydroxyl;
- R.sub.4 can independently be the same or different and are divalent linking groups selected from the group consisting of alkylene, alkarylene, arylene and alkoxyalkylene;
- x is an integer of 0-3;
- y is an integer of 5 or greater;
- q is an integer of 0-3;
- wherein at least one of the following is true:
- q is an integer of at least 1;
- x is an integer of at least 1;
- G.sub.5 comprises at least one -ZSA moiety;
- and
- G.sub.6 comprises at least one -ZSA moiety;
- and
- (C) an anti-bubbling effective amount of dimethicone fluid.
