Abstract
The invention relates to novel hybrid compounds containing at least one polysaccharide entity (PS), such as guar, in which at least one hydroxyl function is substituted by at least one A polyoxyalkylene entity (PEG). The swivel Ro between the entity PS and the entity A is obtained by click chemistry and has the following formula (IL1) or (IL2), in which Z is a carbon or nitrogen atom. These hybrid compounds can be used as emulsifiers, particularly in cosmetics.
