Abstract
An aqueous nail varnish free from nitrocellulose and having improved spreading properties contains 10 to 59 weight percent of a film-forming polymer present in a dispersed state, 0.01 to 1 weight percent of a water-soluble perfluoroalkyl and 40 to 90 weight percent of water.
Claims10
A colored aqueous nail varnish free from nitrocellulose and having spreading properties on the nail, said aqueous nail varnish consisting of:
- (a) 10 to 59 percent by weight of a film-forming polymer present in a dispersed state,
- (b) 0.01 to 1 percent by weight of a water-soluble perfluoroalkyl having the formula:
- (C.sub.n F.sub.2n+1)--R.sub.1 (I)
- wherein C.sub.n F.sub.2n+1 is linear or branched and n ranges from 4 to 16, and R.sub.1 is a residue selected from the group consisting of:
- (i) --SO.sub.3.sup..crclbar. NH.sub.4.sup..sym.,
- (ii) --SO.sub.3.sup..crclbar. N.sup..sym.(R.sub.3).sub.4, wherein R.sub.3 is C.sub.1 -C.sub.4 alkyl,

- (iv) --CO.sub.2.sup..crclbar. N.sup..sym. (R.sub.3).sub.4, wherein R.sub.3 has the meaning given above,
- (v) --SO.sub.2 N(R.sub.3)CH.sub.2 --CO.sub.2.sup..crclbar. X.sup..sym., wherein R.sub.3 has the meaning given above and X represents hydrogen or an alkali metal,
- (vi) --SO.sub.2 NH (CH.sub.2).sub.p N.sup..sym. (R.sub.3 .sub.3 I.sup..crclbar., wherein p represents 1, 2, 3 or 4 and R.sub.3 has the meaning given above, and
- (vii) --SO.sub.2 N(R.sub.3)(CH.sub.2 CH.sub.2 O)--Y, wherein Y represents hydrogen or C.sub.1 -C.sub.4 alkyl, and R.sub.3 has the meaning above,
- (c) 40 to 90 percent by weight of water,
- (d) 0.05 to 5 percent by weight of an organic or inorganic pigment, and
- (e) a cosmetic ingredient selected from the group consisting of a preserving agent, a perfume, a plasticizer, an auxiliary film-forming substance, a thickener, a hydrating agent, a wax, a drying accelerator, a UV filter, a silicone surface-active agent and a mixture thereof,
- the amounts of components (a), (b), (c) and (d) being based on the total weight of said nail varnish.
