Abstract

Cellulose is a polysaccharide with numerous hydroxyl groups and high water absorption capacity, and is the most abundant natural polymer used in the industry. Cellulose-based hydrogels are superabsorbents that provide the ability to create three-dimensional networks. Chemical bonds or other cohesive forces, such as hydrogen bonding or ionic interactions, hold the cellulose chains together. Hydrogels can absorb water and other aqueous liquids into their three-dimensional networks and swell, but they are insoluble in them. Today, there is an increasing demand for biodegradable materials and products made from renewable sources such as cellulose. The biodegradability and environmental friendliness of cellulose have led to its widespread use in personal care products. Cellulose hydrogels act as superabsorbents for these products, which is used as the main absorbent or as an auxiliary absorbent with the ability to protect the skin. Hygienic absorbent cellulose products such as diapers, panty liners, tampons, toilet paper, and paper towels are used as personal care products. These products are available in different absorbency ratings from low to very high. Superabsorbent products are made using cellulose-based hydrogels. In this article, the applications of cellulose-based hydrogel in a variety of personal care products were reviewed.
