  • POLYLACTIC ACID AND POLYETHER COMPOUNDS
    Publication number: 20250002647
    Abstract: Compounds are described which are polylactic acid and polyether copolymers, wherein the compounds comprise: a) at least one of: a sorbitan ester residue, a C6 to C24 fatty alcohol residue or a C6 to C24 fatty acid residue; b) at least 2 lactic acid residues; and c) at least 2 oxyethylene groups; and wherein the compounds comprise at least two ether bonds and at least two ester bonds. A process for producing the compounds is also described, comprising reacting a) at least one of: a polysorbate, a C6 to C24 fatty alcohol ethoxylate or a C6 to C24 fatty acid ethoxylate; and b) lactide; wherein the compound comprises at least 2 lactic acid residues and at least 2 oxyethylene groups, and the use of such compounds as fibre finishes in non-woven materials such as personal hygiene products and/or as surfactants in cleaning applications such as home care formulations.
