Abstract Provided is an oil-based cosmetic preparation which retains a smooth feel. Provided is an oil-based cosmetic preparation containing the following components (A), (B), and (C): (A) a cellulose derivative having a cellulose skeleton in a main chain, in which 67 mol % or more in total hydroxyl groups are substituted with a group &#x2014;O-M-R, wherein M represents CH2 or a carbonyl group C&#x2550;O, and R represents a straight or branched alkyl or alkenyl group having 3 to 40 carbon atoms; (B) an ester oil which is liquid at 25&#xb0; C.; and (C) a hydrocarbon oil which is liquid at 25&#xb0; C., in which a weight ratio (B)/(C) of the component (B) to the component (C) is 8/1 to 1/4.

Oil-based cosmetic preparation

A novel fluorine-containing compound having functions corresponding to those of fluorine is provided, which is stable under various conditions, excellent in compatibility with other solvents, and can be widely utilized as solvents, cosmetics, detergents, emulsifiers, surface finishing agents, lubricants, as well as lubricants or oils in the field of semiconductor/electronics. That is, the present invention provides fluorine-containing ether compounds represented by the general formula (1):

Fluorine-containing ether compound

Fluorine-containing ether compound and gelling agent containing the same

Ether compounds, which are useful as solvents, cosmetics, detergents, lubricants, emulsifiers and so on, are produced by reacting (a) a hydroxy compound with a carbonyl compound of (b) a carbonyl compound under hydrogen atmosphere in the presence of a catalyst with ease and at a low cost. The reaction is carried out while removing out produced water by using a dehydrating agent during the reaction; by distilling off the water by azeotropic dehydration and the like; or by blowing gases such as hydrogen gas to flow through the reaction system.
