Abstract: The present invention relates to novel anhydrous or water-in-oil synthetic ester compositions which are used in formulating dermatological products having uniform structure ranging in consistency from a soft gel to a hard stick. The compositions comprise a new component, dibehenyl fumaric acid ester, which has a melting point of approximately 72-74.degree. C. The dibehenyl fumaric acid ester component has exceptional benefits when used in combination with any cosmetically acceptable oil in varying ratios, to produce homogeneous materials having a uniform structure. The di-behenyl fumaric acid ester according to the present invention may be used to harden or stiffen any cosmetically acceptable oil or water-in-oil emulsions and can be used to create compositions varying widely in viscosity and/or hardness from gels to solid systems such as sticks or to enhance the stability of water-in-oil emulsions.
Abstract: The present invention relates to a novel emollient compound capryl isostearate, which is obtained from capryl alcohol and isostearic acid. These emollient compounds may then be used in dermatological products for their unexpected characteristics and as silicone-free carbon based replacements for the volatile cyclomethicones.
Abstract: Novel self-emulsifying alkoxylate esters are described having a cloud point of less than about 15.degree. C. the structural formula: ##STR1## R.sub.1 contains from 2 to 20 carbon atoms and is selected from the group consisting of aliphatic and aromatic substituents and R.sub.3 is an alkyl or aryl substituent from 1 to 21 carbon atoms. One of R.sub.1 and R.sub.3 must contain greater than 8 carbon atoms.R.sub.2 is: ##STR2## x is from 1 to 10 and y is from 1 to 20 and the ratio of y to x is from 2:1 to 10:1.These alkoxylate esters are particularly useful in preventing the chalking of antiperspirant compositions containing volatile silicone oil by adding to the antiperspirant composition a chalking preventative amount of such ester. The compositions are also useful in a broad range of cosmetic compositions, and form stable oil-in-water emulsions at room temperature.
