Abstract
Abstract A germicidal composition consists of an aqueous suspension of hydrophilic lipid crystals of 1-monolaurin, and preferably also 1-monomyristin, in a quantity of 20-30 percent by weight, and hydrogen peroxide in a quantity of 0.2-5 percent by weight. The hydrophilic lipid crystals stabilize the hydrogen peroxide, to the effect that the composition retains its germicidal power even after having been stored for a long time. Also, the peroxide disintegrates slowly when the composition has been applied onto skin or mucous membrane.
