Provided is an excellent oil-thickening or -gelling agent which is well compatible with various oils and which can freely control the form or viscosity of oily raw materials or cosmetics by changing the quantity thereof added. Also provided are: a gel composition which is useful as a base that permits stable and easy preparation of cosmetics having various viscoelasticities and forms and in which an oil is kept in the form of a gel that has a viscoelasticity falling within the intermediate range between the viscoelasticity of liquid and that of solid, said oil being arbitrarily selected from various oils; cosmetics containing the thickening or gelling agent; and so on.nA thickening or gelling agent for oily raw materials, which contains a novel co-modified organopolysiloxane that contains both a group having a siloxane dendron structure and a hydrophilic group and that preferably has a degree of polymerization of 200 or more; preparations for external application and cosmetics, containing the same; a gel composition containing the co-modified organopolysiloxane; and a process for the preparation of cosmetics or the like, using the same. |
