This product is divided into three types: transparent (both sections do not contain sunscreen), translucent (only one section contains sunscreen), and opaque (both sections contain sunscreen).

　　Element

　　Most capsules are made of gelatin. Gelatin is used in many foods, such as puddings, sweets, preserves, chewable candies, icings, toppings, and dips. In food, gelatin helps to coagulate, thicken, stabilize, and aerate and is a very popular, nutrient-dense, and low-fat food ingredient. Gelatin itself is a water-soluble protein derived from collagen, the main natural protein component of connective tissue. Gelatin is obtained from the skin and bones of animals through a controlled extraction process. There are many types of gelatin. Capsules are made from pharmaceutical-grade gelatin that meets stringent requirements for use in pharmaceutical products. Capsules are made by forming a thin film of gelatin on a stainless steel mold. The gelatin film then dries and hardens to form a capsule, which is then removed from the mold. There are generally two sizes of molds, one for making the capsule body and the other for making the capsule cap with a larger diameter.
