As for this invention, the micro capsule which can be able like below and/or it regards the hydrophobic conversion powder which consists of the nano- capsule: While under existing of the W/O emulsifier making disperse in the oil (a) in the temperature which the aqueous solution of one polymer, is higher than the gel point of the polymer solution at least, (b) agitating this dispersed liquid it cools in the temperature which is lower than the gel point, (c) the micro capsule which was formed and/or it separates the nano- capsule due to decantation, (d) it adds the oil absorption aid to the oily dispersed liquid which is obtained. In addition as for this invention, production method, and the cosmetics of the hydrophobic conversion powder and/or the medical supply, the cleaner and the use in the cleaner it regards.本発明は、以下のようにして得ることができるマイクロカプセルおよび/またはナノカプセルから成る疎水化粉末に関する:(a)少なくとも一つのポリマーの水溶液を、ポリマー溶液のゲル化点よりも高い温度においてW/O乳化剤の存在下に油中に分散させ、(b)この分散液を撹拌しながらゲル化点よりも低い温度に冷却し、(c)形成されたマイクロカプセルおよび/またはナノカプセルをデカンテーションによって分離し、(d)得られた油状分散液に油吸収助剤を添加する。本発明はまた、疎水化粉末の製造方法、並びに化粧品および/または医薬品、洗浄剤および清浄剤におけるその使用に関する。
