Abstract
A personal hand or body washing formulation includes a cationic polymer and an anionic emollient which apparently combine to give a sparingly soluble complex, which is deposited on the skin and is difficult to remove. The deposition results in improved skin feel, including skin softness, skin moisture, skin hydration and skin smoothness. Skin appearance is approved as well. Exemplary cationic polymers include polyquaternium 6, while a preferred anionic emollient is sulfated castor oil. The complex also finds use as the conditioning agent of a cleansing and conditioning shampoo.
