PromoTools Launches New Aroma Hand Soap from 100% Natural Essential Oil 'White Tea & Thyme Natural' Line

PromoTools Co., Ltd. (Headquarters: Bunkyo-ku, Tokyo; Scent Technology Research Institute: Saitama City, Saitama; President and CEO: Kensuke Ogata, hereinafter referred to as 'the company'), a scent technology company that scientifically studies and designs all kinds of fragrances, has launched a new 'Aroma Hand Soap' from its 'White Tea & Thyme Natural' series, formulated with 100% natural essential oils. The product will be sold under the company's own brand and also offered as an OEM product for luxury hotels, ryokans, residences, and premium brands.

The company’s strength lies in its ability to provide end-to-end solutions—from original scent creation tailored to a hotel’s brand concept to amenities and spatial scent design—and this new product is one such OEM offering leveraging that expertise.

This product was developed through the fusion of delicate perfumery by Takeshi Watanabe (Deputy Director and Senior Perfumer at the PromoTools Scent Technology Research Institute), recognized as Japan’s top young perfumer※ who has crafted scents for numerous hotels and luxury brands, and product design expertise by Hiroshi Yokoyama, former General Manager of Product Development at Kose Corporation and current Director of the same research institute. The institute has extensive experience in OEM development that translates brand identities into olfactory experiences, and this product fully embodies its high-level technology and know-how.

The product aims to elevate everyday handwashing into a refined, aromatic moment.

Elevating Daily Habits into Luxurious Moments with Premium Fragrance

With meticulous and frequent handwashing becoming a daily habit, people now use hand soap multiple times a day—before cooking or meals, after going out, and more. Alongside skin gentleness, the quality of fragrance has become increasingly important. In response, the company has developed a new hand soap from its popular 'White Tea & Thyme Natural' series.

Gentle Formula Suitable for Sensitive Skin and Amenity Use in Hotels, Spas, and Lounges

The 'White Tea & Thyme Natural Aroma Hand Soap' is a liquid soap based on potassium soap base. While offering excellent lather and cleansing power, it includes glycerin as a moisturizing agent to protect the skin’s hydration, aiming for a gentle feel suitable even for those concerned about dry or sensitive skin. The simple bottle design blends seamlessly into any space, transforming daily handwashing into a comfortable, luxurious experience. The product is crafted to meet the quality standards of amenities used in hotel rooms, spas, and lounges.

Collaboration Between Japan’s No.1 Perfumer and Former Kose GM

'White Tea & Thyme Natural' opens with a light, fresh citrus note, transitions into delicate floral tones of rose and jasmine, and finishes with the warm, soothing depth of guaiac wood—an elegant, calming fragrance. This signature scent has been widely adopted in diverse spaces such as hotels, showrooms, offices, and luxury spas. Responding to rising consumer interest in health and premium quality, top perfumer Takeshi Watanabe has reconstructed the scent using 100% natural essential oils.

The fragrance is subtle and not overpowering, gently enveloping the senses with each handwash to calm the mind. Designed to complement daily routines, it offers an experience suited to those pursuing a refined lifestyle.
