**A foam pump is a non-aerosol way of dispensing liquid materials. The foam pump outputs the liquid in the form of foam and it is operated by squeezing. The foam pump is widely used in cosmetic products and household chemicals, such as mousse foam cleansing, hand washing liquid, hand sanitizer, facial cleanser, shaving cream, hair conditioning mousse, sun protection foam, spot removers and baby products.
