Application

λ-Carrageenan is a versatile hydrocolloid derived from red seaweed and serves multiple purposes due to its unique chemical structure. As a water-soluble gum, it is characterized by its high sulfate content, making it a strongly anionic polymer. Unlike its gelling counterparts, λ-Carrageenan is a non-gelling fraction primarily composed of highly sulfated D-galactose, which makes it particularly useful in various pharmaceutical and personal care applications where gel formation is undesirable. Its solubility in cold water and its ability to stabilize emulsions and suspensions are key properties that make λ-Carrageenan invaluable. It also enhances the texture and mouthfeel of formulations like creams and lotions, while providing stability to suspensions. Moreover, due to its mucoadhesive properties, λ-Carrageenan is particularly effective in drug delivery systems, particularly in formulations designed for oral and buccal use, demonstrating its broad utility across a range of products and industries.
