  • Publication number: 20230277425
    Abstract: Provided in the present disclosure is a composition comprising hydroquinone or a derivative thereof as an active ingredient, and characterized in that the hydroquinone or the derivative thereof is stabilized by means of poloxamer. The composition of the present disclosure increases the soluble concentration of the hydroquinone or the derivative thereof, can have high melt stability without precipitation even at high concentration in water, can enhance storage stability by preventing oxidation reaction to external stimulations such as heat, oxygen and light, can prevent discoloration, and thus has reduced toxicity induced by an oxidation product of the hydroquinone and can reduce inflammatory response. Also, the composition of the present disclosure can enhance whitening efficacy by enhancing the skin permeability of the hydroquinone or the derivative thereof by means of micelles, and thus is useful for a whitening activity having hydroquinone or a derivative thereof as an active ingredient.

  • Publication number: 20230142512
    Abstract: A porous silicon manufacturing method according to the present invention comprises the steps of: pretreating a silicon precursor and a heat dispersant; and conducting a thermal reduction reaction between the heat dispersant-pretreated silicon precursor and a metal reducing agent by using a rotary reaction chamber. When porous silicon manufactured by the manufacturing method is contained in a secondary battery anode active material and used in secondary batteries, the batteries exhibit high capacity and long lifespan characteristics. The present invention relates to a method for manufacturing porous silicon and a method for manufacturing a secondary battery anode active material containing the porous silicon manufactured thereby, with the aim of solving the problems with silicon materials under development for anode active materials for lithium secondary batteries, including excessive volume expansion during charge/discharge and resultant electrode fracture and lifespan shortening.
