Natural fillers are materials derived from natural sources that are used to enhance the properties of various products. Common examples include cellulose, starch, and clay. These fillers can improve texture, reduce weight, and lower costs in applications such as food, cosmetics, and construction. In addition to their functional benefits, natural fillers are often more environmentally friendly compared to synthetic alternatives. They are biodegradable and can be sourced sustainably, making them a popular choice for eco-conscious consumers. Their use supports a shift towards greener practices in industries like packaging and personal care.
