The present invention relates to a nano-diamond composition containing astaxanthin, capable of having dispersibility, uniformity, and stability by adsorbing water-insoluble astaxanthin to the surface of nano-diamond dispersed in a hydrophilic solvent. The present invention provides a composition having high dispersibility in a hydrophilic solvent by adsorbing astaxanthin, which is water-insoluble and cohesive, to nano-diamond. According to the composition containing nano-diamond and astaxanthin, astaxanthin is able to last in the composition for a long time without being easily deformed by heat, oxygen, or light since the astaxanthin is adsorbed to the nano-diamond. As such, the composition of the present invention is capable of avoiding or reducing the use of a surfactant when used as a cosmetic material, thereby providing a skin-friendly natural cosmetic material. Since astaxanthin is stably kept dispersed and maintained, the unique function and color (antioxidation and red) of the astaxanthin ...
