Production manner of the super hydrophilic parents crocking Characteristic copolymer and the said super hydrophilic parents crocking Characteristic copolymer which include the low-molecular quantitative polysaccharide which is denaturalized with hydrophobic reagent such as displacement succinic acid anhydride. As for aforementioned super hydrophilic parents crocking Characteristic copolymer type, the stimulus for the eye and the skin is low, the appropriate bubble is generated to use with application of the health care formulation and the like.置換コハク酸無水物などの疎水性試薬で変性された低分子量多糖類を含む超親水性両親媒性コポリマー及び該超親水性両親媒性コポリマーの製造方法。前記超親水性両親媒性コポリマー系は、目及び皮膚に対する刺激が低い、ヘルスケア製剤などの用途での使用に適切な泡を発生させる。
