Furthermore as for this invention, being the positive latex, a) 40% super and the monomer unit which is derived, at least from one cation characteristic monomer of mol ratio of 99% or less, b) the monomer unit which is derived, from the N (2 hydroxyethyl) acrylamide of mol ratio of 1% or more and under 60%, c) being optional oil phase and water phase and, at least vis-a-vis water type emulsification system and 100mol% in one oil, 0% super and, the above-mentioned N (2 hydroxyethyl) acrylamide of mol ratio under 30% the monomer unit which at least is derived from one which differs neutral monomer (, this molAs for ratio, N (2 hydroxyethyl) being truly it is smaller than mol ratio of the monomer unit which is derived from acrylamide), and, d) optional, line, divergence or building a bridge which can 0% super and by, the diethylene type of mol ratio of 1% or less or the polymerization of polyethylene type building a bridge monomer cation characteristic high polymer electrolyte and, it includes, it regards the positive latex. This invention regards also the method where it manufactures and uses the above-mentioned positive latex and as a thickener for the cosmetics composition or the medical supply composition.< Selective figure >It is not本発明は、陽性ラテックスであって、油相と、水相と、少なくとも1つの油中水型乳化系と、100mol%に対して、a)40%超かつ99%以下のモル比の、少なくとも1つのカチオン性モノマーに由来するモノマー単位、b)1%以上かつ60%未満のモル比の、N-(2-ヒドロキシエチル)アクリルアミドに由来するモノマー単位、c)任意で、0%超かつ30%未満のモル比の、上記N-(2-ヒドロキシエチル)アクリルアミドとは異なる少なくとも1つの中性モノマーに由来するモノマー単位(なお、このモル比は、N-(2-ヒドロキシエチル)アクリルアミドに由来するモノマー単位のモル比より真に小さい)、及び、d)任意で、0%超かつ1%以下のモル比の、ジエチレン系又はポリエチレン系架橋モノマーの重合によって得られる線状、分岐又は架橋カチオン性高分子電解質と、を含む、陽性ラテックスに関する。本発明は、化粧品組成物又は医薬品組成物用の増粘剤として上記陽性ラテックスを調製及び使用する方法にも関する。【選択図】なし
