▎ 摘　　要

NOVELTY - Graphene nanomaterial comprises graphene nanofibers, graphene oxide and/or reduced graphene oxide, where the graphene nanomaterial has a particle size distribution dn(90) of less than or equal to 0.6 mu m in number of particle and a dv(90) of less than or equal to 80 mu m in volume particle, as measured by laser diffraction particle analyzer. USE - The nanomaterial is useful: as a cosmetic to treat the skin and reduce adipose tissue of the skin, preferably fat in the hypodermis; for preventing or reducing the increase in the volume of adipose tissue and/or the formation of fatty lumps; and for reducing cellulitis, wrinkles and/or varicose veins (all claimed). Test details are described but no results given. ADVANTAGE - The nanomaterial has: Brunauer-Emmett-Teller specific surface area of 100-500 (preferably 300-350) m2/g; impurities of less than 0.01 wt.%; low or no toxicity and good biocompatibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the product from raw graphene nanofibers, graphene oxide or reduced graphene oxide, comprising (a) purifying the raw graphene material, preferably using a strong acid, to remove any metal or impurity present in the graphene raw material, (b) reducing the particle size of the purified graphene nanomaterial, preferably through an exfoliation process, to a particle size distribution, and (c) optionally subjecting the obtained product to a depyrogenization process.
