A non-pyrogenic preparation containing nanoparticles synthesized by magnetotactic bacteria for medical or cosmetic applications. The nanoparticles are constituted by a crystallized mineral central part including predominantly an iron oxide, as well as a surrounding coating without material from the magnetotactic bacteria.

The present invention relates to a composition, in particular cosmetic, in the form of an oil-in-water emulsion, comprising a continuous aqueous phase and a dispersed oil phase in the form of drops (G1) and drops (G2), wherein the size of the drops (G1) is less than 500 μm and the size of the drops (G2) is greater than 500 μm.

A purpose of the present invention is to provide an oil-in-water emulsion composition that is stable even when using solid oils from which it was conventionally considered to be difficult to form large oil-based particles exceeding 50 μm, and also improving the uniformity of the particle sizes and the shapes of the oil-based particles. The present invention relates to an oil-in-water emulsion composition in which oil-based particles containing a solid oil, a liquid oil and a powder are dispersed in a water phase, wherein: the oil-based particles have an average particle size of 50 μm to 10 mm; and the powder is contained inside the oil-based particles.
