Cellobiose esters and particularly &agr; cellobiose octanonanoate has been found able to structure water-immiscible liquids well, and in particular can produce clear structured emulsions. However, such emulsions tend to lose clarity or structural strength during storage. Deviating from &agr;-cellobiose octanonanoate can result in impaired clarity and/or impaired hardness of emulsion sticks. However, acylated cellobiose which contains acyl substituents of formula &mdash;O&mdash;CO&mdash;R in which R represents an n-octyl residue and the percentage Y of the nonanoate acyl substituent &mdash;O&mdash;CO&mdash;R at the anomeric carbon is at least 60% and the percentage A of &agr; anomer is greater than the anomer and not higher than A&equals;74.5 &plus;0.2Y when Y is up to 92% and not higher than A&equals;161&minus;0.74Y when Y is greater than 92% offers the production of sticks combining structurant stability with product clarity and hardness.
