Abstract: The present invention relates to a dimeric urethane compounds derived from monohydric alcohols, generally fatty alcohols, and a diisocyanate according to the following reaction scheme: wherein R1 is selected from the group of saturated, unsaturated or halogen substituted linear, cyclic or branch-chained hydrocarbons and R2 is a linear, cyclic or branch-chained alkyl or aminoalkyl group ranging from two to 200 carbon atoms, preferably two to 50 carbons, more preferably 6 to 36 carbons, said urethane compound being substantially free from terminal hydroxyl groups.

Abstract: The present invention is directed to monomeric and polymeric compositions based upon polymeric urethane surfactants which are derived from linear, branched, or aromatic compounds of synthetic or natural origin, preferably from tertiary amines and diisocyanate compounds. The urethane polymers of the present invention may be in the form of betaines, quaternium salts, tertiary amine salts or N-oxides. The compounds of the present invention may be incorporated into personal care formulations such as cosmetics, dental care products and toiletries to improve at least one and preferably two or more characteristics of such formulations.

Abstract: The present invention also relates to chemical compositions comprising the neutralization product of at least one amine neutralization compound (preferably, a diamine) and a carboxylic acid (preferably, a dicarboxylic acid), said amine neutralization compound comprising about 1% to about 100% by weight (of the total amount of amine neutralization containing compound) of a first amine compound and 0% to about 99% by weight of a second amine compound different from said first amine compound, said first amine compound being a polyamine containing at least one tertiary amine group and at least one quaternary amine group, said tertiary amine group of said first amine reacting with said carboxylic acid group to produce a tertiary ammonium carboxylate salt, said second amine compound containing at least one primary, secondary or tertiary amine group with the proviso that when said second amine contains only primary and/or secondary amine groups, the amount of said second amine in said amine neutralization compound i

Abstract: This disclosure introduces the use of an isophorone diisocyanate urethane polymer of naturally occurring castor oil as an active ingredient for skin and personal care compositions and products.

Abstract: This invention is concerned with the use of neopentanoate esters as novel cosmetic emollients for sunscreen products.The use of isoarachidyl neopentanoate in sunscreen formulations offer new and unexpected results over the use of similar esters previously disclosed.The isoarachidyl neopentanoate has a minimal odor, good stability, water white color, higher sun protection factor values, good emolliency, good crystal solibilization, very low freeze point. It forms the emollient basis for a new way to make very high sun protection factor products.

Abstract: This invention is concerned with various physical mixtures of quaternary ammonium compounds and tertiary amine salts of long-chain acids.These self-emulsifiable and self-dispersing mixtures exhibit synergistically enhanced properties including: surfactant and emollient properties, anti-static properties, anti-tangle properties, lubricant properties, and film forming properties.These unique properties and characteristics are utilized in various hair and skin conditioner formulations.
