Patent number: 6974804Abstract: Acylated cellobiose compounds (CHME) which satisfy the formula; wherein X represents an acyl group (R—CO—) or H, Z represents an acyl group (R?—CO—) or H and not more than a minority of X+Z residues represent H, R represents a saturated or unsaturated, linear or branched chain hydrocarbon residue of 5 to 31 carbon atoms and R? represents a residue, different from R, which is: (i) a saturated or unsaturated, linear or branched chain hydrocarbon residue of 1 to 31 carbon atoms, or (ii) an aromatic hydrocarbon residue, or (iii) a cycloaliphatic hydrocarbon, each optionally substituted. CHME esters are particularly suited to thickening or structuring a water-immiscible liquid, for example, a phase in a cosmetic formulation, such as antiperspirant or deodorant formulations, eg water in oil emulsions and especially translucent ones.Type: GrantFiled: October 17, 2001Date of Patent: December 13, 2005Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Kevin Ronald Franklin, Andrew Hopkinson, Nicholas Webb, Michael Stephen White

Patent number: 6680048Abstract: 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 —O—CO—R in which R represents an n-octyl residue and the percentage Y of the nonanoate acyl substituent —O—CO—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=74.5 +0.2Y when Y is up to 92% and not higher than A=161−0.74Y when Y is greater than 92% offers the production of sticks combining structurant stability with product clarity and hardness.Type: GrantFiled: October 17, 2001Date of Patent: January 20, 2004Assignee: Unilever Home & Personal Care USA, a division of Conopco, Inc.Inventors: Lynda Grainger, Kathryn Elizabeth Gransden, Andrew Hopkinson, Adam Jan Kowalski, Nicholas Webb, Michael Stephen White
