The composition includes: 18 wt % to 25 wt % of a first organic acid compound; 15 wt % to 20 wt % of a second organic acid compound; 8.1 wt % to 9.9 wt % of an inorganic acid compound; 1 wt % to 4.9 wt % of a sulfonic acid compound; 10 wt % to 20 wt % of a hydrogen sulfate salt compound; 1 wt % to 5 wt % of a nitrogen-containing dicarbonyl compound; 1 wt % to 5 wt % of an amino acid derivative compound; 0.1 wt % to 2 wt % of an iron-containing oxidizing agent compound; and a balance amount of water.

Etchant composition and manufacturing method of metal pattern using the same

Disclosed is a composition containing an active ingredient or ingredients comprising an extract or extracts of one or more constituents selected from the group consisting of, rose, rhubarb,and cortex. The composition is efficacious in suppressing acneiform pigment deposition and/or pitted scars, and can be used to advantage in various ways in the fields of cosmetics, foods and drugs.

Composition containing a natural extract

Disclosed is herein a composition comprising hexamidines, derivatives thereof, or pharmaceutically acceptable salts thereof; and retinoids, derivatives thereof, or pharmaceutically acceptable salts thereof, as an active ingredient. The composition of the present invention has effects for preventing, improving or treating acne; controlling sebum; pore-controlling; and preventing, improving or treating skin pigmentation. Also, the composition of the present invention could alleviate skin-irritations caused with retinoids by including ceramides.

Composition for skin improvement comprising hexamidines and retinoids

Provided are: a multi-layered lamellar granule comprising a nucleating agent, a ceramide-containing artificial stratum corneum lipid lamellar layer which encases the nucleating agent and a polymer layer disposed on the artificial stratum corneum lipid lamellar layer; and an external skin application composition comprising the same. The external skin application composition shows improved moisturizing and barrier repair capabilities when applied to the skin, which can be advantageously used in cosmetics and pharmaceuticals.

Multi-layered lamellar granule and skin external application composition containing same

Provided is a pseudolipid complex mixture comprising a pseudoceramide and a stearic acid and an external skin application composition comprising the same. The complex mixture has improved phase stability and a structure similar to that of the stratum corneum which can retain water and other beneficial materials, and accordingly the composition comprising the same can be used as an external skin application composition having improved moisturization and barrier repair capabilities.
