Abstract: The present application pertains to the field of cosmetics, more specifically the field of antimicrobial and/or bacteriostatic and/or bactericidal cosmetic agents, preferentially acting on bacterial and/or fungal strains on the human epidermis. Proposed is a use of dianhydrohexitol, preferentially isosorbide, to reduce the number of bacterial or fungal strains on the skin, in particular in the cutaneous microbiome, causing acne, dandruff buildup and bad odors.

Abstract: The present application pertains to the field of cosmetics, more specifically the field of antimicrobial and/or bacteriostatic and/or bactericidal and/or antifungal cosmetic agents, preferably acting on bacterial and/or fungal strains in cosmetic preparations. Proposed is a use of dianhydrohexitol, preferably isosorbide, to reduce or eliminate the effects of the degradation of said preparation contaminated by microorganisms of the human cutaneous microbiome.

Abstract: The invention relates to the field of film-forming agents for cosmetic or dermatological use, that are capable of conferring a barrier effect or a fixative effect on a cosmetic preparation. The barrier effect makes it possible to protect the skin from environmental pollution, for example microparticles and volatile organic compounds, and more particularly from urban atmospheric pollution. The fixative effect makes it possible to reduce or eliminate the transfer of pigments and/or dyes, and to increase the hold of the hairstyle or the shaping of head hair, body hair or eyelashes.
