Abstract
The present invention is directed to compositions, particularly cosmetic compositions, in which the oil is thickened using at least one copolymer which has a hydrophobic functionality sufficient to provide at least partial solubility and optionally stability in oil and a hydrophilic functionality sufficient to provide thickening of the oil. Use of such copolymers as thickening agents are advantageous in that they are soluble and stable in the oil phase. Further, sufficient thickening may be accomplished using very low amounts of these copolymers without the use of additional polymeric thickeners.
