<p>PROBLEM TO BE SOLVED: To obtain the subject composition capable of satisfying test items of the Japanese Pharmacopeia and excellent in steam sterilization resistance, transparency or the like by adding a specific organic alkali metallic salt, a neutralizing agent and a nucleophilic agent thereto. SOLUTION: This composition is obtained by compounding (A) a propylene homopolymer or a propylene-ethylene random copolymer having <=1 ppm metallic titanium content and 0.5-70 g/10 min melt flow rate(MFR) in which the ethylene content in the random copolymer is <=3 wt.% with (B) 0.025-0.15 wt.% organic alkali metallic salt such as an alkali metallic salt of a carboxylic acid, (C) 0.025-0.15 wt.% basic polyvalent metallic salt of an organophosphoric ester represented by formula I (R<1> is H or a 1-4C alkyl; R<2> and R<3> are each H or a 1-12C alkyl; M is a group III or IV metallic atom of the periodic table; X is HO or O) and (D) 0.01-0.10 wt.% compound hydroxide salt compound represented by formula II [(x) is 0<(x)<=0.5; (m) is <=3] and/or formula III [X is an inorganic or an organic anion; (n) is the valence of X].</p> |
