- i) from about 0.5% to about 5% of polyquaternium-10 having a molecular weight of from about 400,000 to about 1,500,000 and charge density of from about 0.6 to about 3 meq/gram;
- and
- ii) from about 0.01% to about 5% of a volatile perfume;
- b) from about 5% to about 50% of a surfactant component comprising:
