A Refined Scent Turns a Daily Habit Into a Small Luxury
In recent years, thorough and frequent hand washing has become part of daily life, with people washing their hands many times a day, whether before cooking or meals or after going out. Alongside gentleness on the skin, the quality of scent has also become an increasingly important factor. With this in mind, Promotool developed a new hand soap building on its popular "White Tea & Thyme Natural" series.
The "White Tea & Thyme Natural Aroma Hand Soap" is a liquid soap based on a potassium soap base. While delivering strong lathering and cleansing power, it also contains glycerin as a moisturizing ingredient to help protect the skin's moisture, aiming for a gentle feel that is easy to use even for those concerned about rough skin or with sensitive skin. The simply designed bottle blends into any space, turning everyday hand washing into a comfortable, small luxury, with a quality intended to suit its use as an amenity in hotel rooms, spas, and lounges.
A Top Domestic Perfumer※ and a Former Cosmetics Executive Team Up
"White Tea & Thyme Natural" is a refined, calming fragrance that opens with a light, fresh citrus note, moves into delicate rose and jasmine florals, and finally settles into the gentle warmth of guaiac wood. It is one of Promotool's signature scents, previously adopted in a variety of spaces including hotels, showrooms, offices, and luxury spas. Reflecting the recent rise in health and quality consciousness, top domestic perfumer Takeshi Watanabe rebuilt the fragrance using 100% natural essential oils as the new "White Tea & Thyme Natural."
The scent is designed not to assert itself too strongly, instead spreading gently with each hand wash to help settle the mind. As a fragrance that accompanies daily habits, it aims to offer an experience suited to those who value a refined lifestyle.
Promotool also offers original fragrance blending and OEM development tailored to each hotel brand's concept.
