A dermatologic preparation containing at least one of the benzoic acid derivatives represented by general formula (I) and pharmacologically acceptable salts thereof, having a sufficient effect of inhibiting sebum secretion and being free from side effects, thus being safe for the human body, wherein R¹ represents -OH, -OR³ or -NHR³; R² represents hydrogen, lower alkyl or lower alkoxy; R represents -OR⁴ or (II); R³ represents alkyl, alkenyl or hydroxyalkyl; R⁴ represents C₄-C₁₀ linear or branched, saturated or monounsaturated alkyl or cycloalkylalkyl; X represents -O- or -NH-; and n represents 1 or 2.
It has been desired to develop a highly preservative and antibacterial cosmetic composition that can easily be applied to both emulsion and non-emulsion type cosmetics. It has also been desired to develop a method of improving a preservative and/or antibacterial effect(s) of a cosmetic composition comprising polyorganosiloxane-containing epsilon-polylysine and thereby reducing the amount of antibacterial preservative agent to be used. There is provided a cosmetic composition comprising one or a combination of two or more of polyorganosiloxane-containing epsilon-polylysine compounds obtained by reacting epsilon-polylysine with polyorganosiloxane or a physiologically acceptable salt thereof, and polyhydric alcohol.
