The term "acrylic nail polish" can apply to two types of finger nail polish. One is a polish produced specifically for use on acrylic or false nails. The other is a water-based acrylic paint.
Environmentalist concerns have sparked some research into the claims that water based acrylic nail polish is safer than enamels. Enamel nail polish is categorized as a hazardous material. Water-based acrylic nail polish has been touted as a safer type of paint that is non-combustible and can be considered more environmentally friendly. The ingredient list of many acrylic polishes is vague, listing "acrylic polymer emulsion" as one of the main ingredients. Since these emulsions are not always chemical-free, there is some debate about just how environmentally friendly the paints are.
