  • Patent number: 8232321
    Abstract: The present invention is to provide a new compound having a rough skin improving effect, excellent in safety, excellent in texture in use, especially free of sticky feeling, excellent in refreshing feeling, and capable to improve the base agent stability as a component. An alkylene oxide derivative is characterized by being represented by the below-described general formula (I): (formula I) Z—{O-[(AO)a-(EO)b]-R}2??(I) (In the formula, Z is the residue obtained by removing hydroxyl groups from the dimer diol, EO is an oxyethylene group, AO is an oxyalkylene group having 3 to 4 carbon atoms, and the addition form is block-type. The symbols a and b are the average addition mole numbers of the above-described oxyalkylene group and the oxyethylene group, respectively, and they are 1?2 a?150 and 1?2 b?150. The percentage of the oxyethylene groups with respect to the sum of the oxyalkylene groups having 3 to 4 carbon atoms and the oxyethylene groups is 10 to 99 mass %.
