Title
(EN) TOPICAL ANTIMICROBIAL MICROEMULSIONS
(FR) MICROÉMULSIONS ANTIMICROBIENNES TOPIQUES
Abstract
(EN)
In one aspect, the present disclosure is directed to a topical antimicrobial composition, including: a lipophilic component including a surfactant system with an HLB value of less than 10; an amphiphilic component including an antimicrobial compound; and an aqueous hydrophilic component. The composition includes less than 10 wt% of lower monohydric alcohols, based on the total weight of the composition, and is in the form of a microemulsion at room temperature with a disperse phase having droplets with a particle size of 5 nm to 400 nm.
(FR)
Selon un aspect, la présente invention concerne une composition antimicrobienne topique, comprenant : un constituant lipophile comprenant un système tensioactif ayant une valeur HLB inférieure à 10 ; un constituant amphiphile comprenant un composé antimicrobien ; et un constituant hydrophile aqueux. La composition comprend moins de 10 % en poids d'alcools monohydriques inférieurs, par rapport au poids total de la composition, et se présente sous la forme d'une microémulsion à température ambiante avec une phase dispersée comprenant des gouttelettes ayant une taille de particule de 5 nm à 400 nm.
