A food additive useful for lowering serum cholesterol in humans contains a sterol or stanol ester of a fatty acid or a dicarboxylic acid ester of a sterol or stanol made by reacting a sterol, stanol and a carboxylic acid in the presence of an effective amount of a catalyst selected from the group consisting of calcium oxide, calcium hydroxide, a calcium salt of a carboxylic acid, magnesium hydroxide and combinations thereof described herein below.

Food additive compositions containing sterol esters, solubilizing agents, dispersants and antioxidants

A compound of formula: wherein each R group independently is C-Carylene group, a straight or branched chain C-Calkylene group optionally containing an arylene group, or a C-Cstraight chain alkylene group containing one or more &#x2014;NH&#x2014; groups in the alkylene chain, each X is &#x2014;O&#x2014;, &#x2014;S&#x2014;, or &#x2014;NR&#x2014; where Ris hydrogen or C-Calkyl, each AO group is independently ethyleneoxy, 1,2-propyleneoxy, or 1,2-butyleneoxy, n, m and p is fromtoand the sum of n, m and p is from 4 to 50, and the Ris independently &#x2014;CH-CH(OH)&#x2014;R, wherein each Rindependently represents a C-Csaturated or unsaturated, substituted or unsubstituted hydrocarbon group. The compound has surfactant and defoaming properties and is useful in latex paint, an ink, an adhesive, or a metal working compositions.

Lanolin-free lanolin substitute compositions comprising:

Vegetable substitute for lanolin

Lanolin-free lanolin substitute compositions comprising: A) from about 50 to about 95% by weight, of at least one plant sterol fatty acid ester; B) from about 1 to about 10% by weight, of at least one polyglyceryl di-polyhydroxy fatty acid ester; C) from about 1 to about 10% by weight, of at least one polyglyceryl di-fatty acid ester; and D) from about 0.25 to about 2% by weight of at least one glyceryl fatty acid ester.

Processes for preparing color-stable, low-impurity tocopherol compositions are described, wherein the processes comprise: (a) providing a protecting group-substituted tocopherol compound, for example an acetate of a natural-source tocopherol compound; (b) purifying the protecting group-substituted tocopherol compound, for example through crystallization; and (c) solvolyzing the purified compound to form free tocopherol. Also described are the tocopherol compositions prepared thereby.

Sterol esters as food additives

Fatty acid esters of alkylene glycols corresponding to the formula R,COO(AlkO),H are thickeners for aqueous surfactant solutions, particularly for personal care products.

Thickened aqueous surfactant solutions

A process for thickening a water-in-oil and oil-in-water emulsion involving adding to the emulsion a thickening agent consisting of an alkyl or alkenyl oligoglucoside ester formed by esterifying an alkyl or alkenyl oligoglycoside corresponding to formula I:

Esters of alkyl and/or alkenyl oligoglycosides with fatty acids

Fatty acid polyethylene glycol esters of the formula (I):

Process for the production of fatty acid polyethylene glycol esters

Alkyl polyglycoside ether carboxylates

Fatty acid esters of isethionate salts are made by reacting ethylene oxide and a bisulfite salt in an aqueous solution while maintaining the pH in the range of from about 5.5 to about 6.5 and while maintaining the temperature in the range of from 25.degree. C. to 85.degree. C. to form an isethionate salt. The isethionate salt is then esterified with a fatty acid to produce a product having little or no unwanted fatty acid esters of ethylene glycol.

Process for making isethionate ester salts

Fatty acid esters of isethionate salts are made by reacting ethylene oxide and a bisulfite salt, that may be made in situ, in aqueous ammonia while maintaining (1) the pH in the range of about 5.5 to about 6.5 and (2) the temperature in the range of 25.degree. C. to 85.degree. C. to form an isethionate salt. The isethionate salt is then esterified with a fatty acid to produce a product having little or no unwanted fatty acid esters of ethylene glycol.

There is provided a composition and process for preparing self-emulsifying or emollient agents comprising reacting from about 1 mole of azelaic acid with from about 1 to about 1.25 moles of a C12-18 fatty alcohol to form an azelaic acid monoester having the general formula I-IV: ##STR1## wherein R is a C12-18 fatty alcohol, and the product contains from about 40 to about 50 weight percent of (I), from about 50 to about 60 weight percent of (II), from about 1 to about 2 weight percent of (III), and from about 0 to about 1 weight percent of (IV), all weights being based on the weight of said self-emulsifying or emollient agent.

Self-emulsifying and/or emollient agents
