Carrageenan, as a good coagulant, can replace the usual AGAR, gelatin and pectin.

The application of carrageenan in the daily chemical industry such as detergent and cosmetics: the detergent added to carrageenan has a better effect on preventing contamination than methyl cellulose. In liquid detergent, it can improve its dispersion and storage performance. In cosmetics, because carrageenan is easily adsorbed by the skin, it can be mixed with glycerin to make emollients. It can be used as an emulsifier in some lotions and shampoos to make the product soft and smooth, and the stability of the emulsion is also improved.
