Defining some scientific terms: Contact angle, wetting, refractive index, and specific gravity

Yesterday, we took a look at some concepts we’ll need when discussing silicones, esters, and thickeners for surfactants. Today, let’s take a look at a few more. Contact angle: “The contact angle is defined as the angle the water makes with the surface. In this illustration, a low contact angle (θ<90 ̊) means the surface…
