Tapioca starch is a widely used ingredient in cosmetics, personal care, and skincare formulations. Depending on its function, it may serve as a moisturizer, preservative, emulsifier, or active ingredient to enhance the overall effectiveness and performance of a product.
Tapioca (/ˌtæpiˈoʊkə/; Portuguese: [tapiˈɔkɐ]) is a starch extracted from the tubers of the cassava plant (Manihot esculenta, also known as manioc), a species native to the North and Northeast regions of Brazil, but which has now spread throughout parts of the World such as West Africa and Southeast Asia. It is a perennial shrub adapted to the hot conditions of tropical lowlands. Cassava copes better with poor soils than many other food plants.

Tapioca is a staple food for millions of people in tropical countries. It provides only carbohydrate food value, and is low in protein, vitamins, and minerals. In other countries, it is used as a thickening agent in various manufactured foods.
