Patent number: 6737048Abstract: Structured antiperspirant emulsion formulations for topical application to human skin in a cosmetic method for controlling sweat and body odor generation can suffer from problems of impaired sensory properties and impaired efficacy (sweat reduction), which are ameliorated or overcome in structured antiperspirant emulsions in which (%s by weight of the emulsion) i) the hydrophilic phase comprises 25 to 55%; ii) the hydrophilic phase contains 0 to 15% polyhydric alcohol; iii) the emulsifier comprises an alkyl dimethicone copolyol; iv) the weight ratio of the hydrophilic phase to the emulsifier is selected in the range of at least 60:1 v) the structurant comprises an acylated sugar and vi) the water-immiscible oil and the structurant are present in a weight ratio of 1.5:1 to 8.5:1.Type: GrantFiled: March 13, 2002Date of Patent: May 18, 2004Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Sven Jorg Willi Max Abend, Jean-Philippe Andre Roger Courtois, Martin Peter Cropper, Neil Robert Fletcher, Lynda Grainger, Angela Mary Murphy

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

Patent number: 6241976Abstract: An antiperspirant composition is a structured emulsion of a continuous phase containing water-immiscible liquid carrier plus a structurant, and a disperse phase which is a solution of antiperspirant active in water or a mixture of water and water-soluble solvent. The structurant is a fully or partially esterified saccharide. The compositions give low visible residue when applied to skin or to clothing.Type: GrantFiled: April 12, 2000Date of Patent: June 5, 2001Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Isabelle Claire Esser, Kevin Ronald Franklin, Lynda Grainger, Adam Jan Kowalski, Kathryn Elizabeth Rowe

Patent number: 6231841Abstract: Antiperspirant compositions herein comprise an antiperspirant active, a carrier and a structurant for the carrier which comprises an effective concentration of a combination of at least one sterol and at least one sterol ester, to form a solid or a soft solid. The compositions can be anhydrous and in the form of a suspension of antiperspirant active, or can comprise aqueous emulsions. A particularly suitable sterol comprises &bgr; sitosterol and a particularly preferred sterol ester comprises oryzanol. Preferably the mole ratio of sterol to sterol ester is in the range of 3:1 to 1:2.Type: GrantFiled: April 12, 2000Date of Patent: May 15, 2001Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Kevin Ronald Franklin, Lynda Grainger, Adam Jan Kowalski
