  • Patent number: 6447791
    Abstract: A clear cosmetic gel composition comprising: (a) an aqueous phase comprising: (i) water, and (ii) at least one cosmetically active ingredient; (b) a coupling agent; (c) an oil phase comprising: (i) a silicone-containing solvent, and (ii) an isoparaffin solvent having a boiling range between about 100 to 340° C., wherein the isoparaffin constitutes between about 1 to 75% by weight, of the total of the oil phase; and (d) silicone-containing surfactant.

  • Patent number: 5976706
    Abstract: Polyesterdiols having low viscosities of less than 3500 cps, high content of non-volatile matter in excess of 96 wt %, and narrow molecular weight distribution of less than about 1.4 are prepared by esterification of one or more aliphatic dicarboxylic acids or ester derivatives thereof using at least a 1.5 molar excess of one or more aliphatic diols until an acid number of less than 20 is achieved, and stripping excess diol from the polyesterdiol reaction product. Where esterification catalyst is used, catalyst is substantially removed prior to stripping excess unreacted diol from polyesterdiol reaction product. The polyesterdiols so produced are useful as (i) curable components in thermosettable resin compositions, particularly compositions essentially free of volatile organic solvent and also containing a crosslinking agent and a reactive hardening agent: and/or (ii) useful as coatings, paints and adhesives, providing coatings with very low content of volatile organic compounds.
