Etsuko Watanabe

Hello! I'm Etsuko Watanabe of Primadonna, a soap-making instructor in Japan.

Up until now, this channel has brought you the world of beautiful and sophisticated "designer soaps" .

From now on, I'll take it a step further and add the perspective of "soap science" (scientific verification) to help you control those beautiful designs as you wish!

Based not only on intuition but also on 10 years of experience and solid experimental data, I'll logically unravel the mysteries.

I'll deliver videos that combine beautiful designs you'll want to display with the science that satisfies your intellectual curiosity, making soap making 100 times more enjoyable from tomorrow onwards.
