Problem to be solved: to provide an organic acid such as ascopheric acid or an increased viscosity composition which does not lose viscosity even in the presence of the salt thereof. Solution: a viscous composition comprising a polyhydric alcohol, water and organic acids and a lipid peptide type compound comprising at least one of the compounds represented by the following formulae (1) to (3) or a pharmaceutically available salt thereof. In Formula 1, R1 represents an aliphatic group of 9 to 23 carbon atoms, R2 represents a hydrogen atom or an alkyl group of 1 to 4 carbon atoms that can have a branched chain of 1 or 2 carbon atoms, R3 represents - (CH2) N-X group, n is 1 Represents a number of 4 to 4, wherein X represents an amino group, a guanidino group, a - CONH2 group, or a five membered ring group or six membered ring group or a fused heterocyclic group comprising five membered and six membered rings capable of having one to three nitrogen atoms No selection【課題】アスコルビン酸等の有機酸およびそれらの塩の存在下でも粘性を失わない増粘性組成物を提供すること。【解決手段】多価アルコール、水および有機酸と、下記式(1)乃至式(3)で表される化合物又はその薬学的に使用可能な塩のうちの少なくとも一種からなる脂質ペプチド型化合物とを含む増粘性組成物。【化1】(式中、R1は炭素原子数9乃至23の脂肪族基を表し、R2は水素原子、又は炭素原子数1若しくは2の分枝鎖を有し得る炭素原子数1乃至4のアルキル基を表し、R3は-(CH2)n-X基を表し、nは1乃至4の数を表し、Xはアミノ基、グアニジノ基、-CONH2基、又は窒素原子を1乃至3個有し得る5員環基若しくは6員環基又は5員環と6員環から構成される縮合複素環基を表す。)【選択図】なし
