Abstract:
A base composition made by combining:(a) 0.5-80 percent by weight based on the total weight of the composition of at least one siloxane-based polyamide;(b) 5-95 percent by weight silicone fluid; and(c) if (a)+(b) do not equal 100 percent, then a portion of solvent sufficient to make 100 percent, wherein:the siloxane-based polyamide is formed from units of Formula A ##STR17## where: (1) n is a number selected from the group consisting of 1-500, where n is the number of units in the polyamide;(2) DP is an average value for degree of polymerization of a siloxane portion of the polyamide and is selected from the group consisting of 1-700;(3) X is a linear or branched chain alkylene having 1-30 carbons;(4) each of R.sup.1 -R.sup.4 is independently selected from the group consisting of methyl, ethyl, propyl, isopropyl, a siloxane chain, and phenyl, wherein the phenyl may optionally be substituted by 1-3 members from the group consisting of methyl and ethyl; and(5) Y is selected from the group consisting of linear or branched chain alkylenes having 1-40 carbons, wherein the alkylene group itself may optionally be substituted by at least one member selected from the group consisting of(i) hydroxy;(ii) C.sub.3 -C.sub.8 cycloalkane;(iii) 1-3 members selected independently from the group consisting of C1-C3 alkyls; phenyl optionally substituted by 1-3 members independently selected from the group consisting of C1-C3 alkyls;(iv) C1-C3 alkyl hydroxy; and(v) C1-C6 alkyl amine;or Y may be Z where Z=R.sup.20 T(R.sup.22)R.sup.21 where each of R.sup.20, R.sup.21 and R.sup.22 is independently selected from the group consisting of linear and branched C1-C10 alkyl or alkylene groups; and T is selected from the group consisting of CR, where R is selected from the group consisting of hydrogen, the group consisting of the group defined for R.sup.1 -R.sup.4 ; and a trivalent atom selected from the group consisting of N, P and Al; and wherein each value for X, Y, DP and R.sup.1 -R.sup.4 may be the same or different for each unit in the polyamide to form a clear stick or gel.
