Abstract

The gels of the the invention may be made non-adhearing, non-sticking, non-tacky by incorporating an advantage amount of fatty acids, metal stearates, and waxes.

Claims

1. A composition comprising:

a non-adhearing gel formed from (a) 100 parts by weight of one or more high viscosity block copolymer;

(b) from about 300 to about 1,600 parts by weight of a plasticizing oil;

(c) a selected amount of one or more fatty acids or metal stearates or a mixture thereof in combination with;

(d) a selected amount of one or more waxes or fatty amides or a mixture thereof said amounts of (c) and (d) being sufficient to produce a substantially non-adhering gel;

said composition characterized by a gel rigidity of from about 20 to about 800 gram Bloom.

2.
