1. (rare) Cleansing.not-comparablerare

2. (rare) Astringent; detergent.not-comparablerare

3. (chemistry, physics, of a liquid crystal) Whose molecules are aligned in layers, with the molecules lying perpendicular to the plane of the layers.Examples: "The smectic phases, which are found at lower temperatures than the nematic, form well-defined layers that can slide over one another in a manner similar to that of soap.[…]There are many different smectic phases, all characterized by different types and degrees of positional and orientational order.^([Wikipedia])"; "Before studying the fluctuations and defects of the bilayers in the smectic phase, one should first characterize the equilibrium structure of the simulated lamellar phase."not-comparable
