A method for preparing an ester bleach activator compound is disclosed. The method includes (A) preparing fatty acid monoester; (B) making chloroformate by reacting the fatty acid monoester with at least one selected from the group consisting of phosgene, diphosgene and triphosgene in the presence of base; and (C) reacting the chloroformate with hydroxybenzene, its derivatives, or its salts in solvent. According to the method, the ester bleach activator compound can be made in a simple and economic way.

The present invention relates to a fusion peptide, in which a self cell-penetrating Tat peptide having a self penetrating signal is bound to a human Type-I collagen C-terminal derived peptide, a preparation thereof, and a skin anti-aging cosmetic composition comprising the same. Since the fusion peptide, in which the Tat peptide is bound to the human Type-collagen C-terminal derived peptide is highly stable and has a superior skin absorption capability, the present invention provides a skin anti-aging agent having superior synthesis of collagen and hyaluronic acid, anti-aging effects, and improved durability of the effects.
