Description

Preparation method of scrub using room-temperature processing

The present invention relates to a method for producing a scrub agent and a scrub agent composition prepared therefrom.

The scrub agent has an abrasive effect of removing contaminated sweat or sebum metabolites, which are adsorbed or deposited on the aging stratum corneum on the skin epidermis, with the stratum corneum, and by applying friction with soap, detergent or emulsion base. It refers to a solid substance having the effect of removing the contaminants deposited on the skin.

Conventional scrub preparations include carnauba wax, candrina wax and the like, natural vegetable waxes, ozokerite, paraffin lead, carbo wax and the like obtained from petroleum-based waxes, natural alcohols such as cetyl alcohol and stearyl alcohol, The wax or higher alcohols used are waxes or alcohols having a melting point of 55 to 80 ° C., and thus, the bath products containing the scrub preparation are emulsified by heating at 60 to 80 ° C. in the formulation of each composition. The process will be carried out. At this time, the manufacturing process that uses hot water or the raw material using the heating emulsification method, and the manufacturing process that requires additional facilities such as a boiler facility occurs.
