Oil-in-water emulsions can be formed using surfactants with biospecific headgroups. Emulsion droplets adhere to surfaces of microorganisms or to various biological surface bearing appropriate adhesins, thus delivering surfactant materials directly to various surfaces. Lipophilic materials and essential oils can be targeted in this way. The emulsions may be incorporated into oral hygiene non-food compositions or compositions for topical application to skin, hair or nails.

catalytic performances of sulfonated mesoporous carbons in the glycosylation of carbohydrates with alkyl alcohols. Catalytic performances were compared to common solid acid catalysts previously reported for this reaction. Under optimized conditions, the targeted alkyl glycosides were obtained in 85% yield, together with a turn over frequency and a space time yield higher than those of the best heterogeneous
