Earth Chemical Launches Revitalizing Kiki-yu Fine Heat Bath Additive for Fatigue Relief

New Product Launch: Kiki-yu Fine Heat Refreshing Maintenance



Earth Chemical Co., Ltd., headquartered in Chiyoda, Tokyo, is set to introduce its latest product, the Kiki-yu Fine Heat Refreshing Maintenance, on March 23, 2026. This innovative bath additive, enriched with effervescent carbonic acid, aims to enhance the bathing experience while providing effective relief from fatigue during the sweltering summer months.

Addressing Summer Fatigue


Recent meteorological data has shown a rising trend in both scorching hot days and intense summer heat, leading to longer periods of high temperatures. According to a survey, around 40% of customers frequently experience fatigue, reflecting the chronic exhaustion faced by many in today's fast-paced lifestyle. While showers might seem sufficient during the hot weather, the discomforts brought on by air conditioning and heat can build up easily. Recognizing this need, Earth Chemical has developed a product designed to boost the benefits of bathing, enhance blood circulation, and facilitate fatigue recovery while keeping the body refreshingly cool post-bath.

Key Features of Kiki-yu Fine Heat Refreshing Maintenance


High Concentration Carbonic Acid


The Kiki-yu Fine Heat series utilizes a unique formulation with high concentration carbonic acid and mineral-rich hot spring extracts (sodium sulfate) to tackle persistent fatigue. This combination enhances the effects of bathing, promoting better blood circulation and metabolism, while alleviating summer fatigue, shoulder stiffness, and lower back pain.

Cool and Refreshing Experience


With an extra dose of menthol, this bath additive provides a crisp and invigorating sensation. While customers warm up during their bath, they will emerge feeling fresh without any sticky residue, making bathing in hot weather enjoyable.

Condition-Enhancing Ingredients


To further support fatigue recovery, the product incorporates citric acid and vitamin C (a moisturizing element), catering to young individuals and those with active lifestyles who require quick and efficient recovery. This makes it an excellent choice for those seeking a rejuvenating bath experience.

Invigorating Scent and Indulging Color


The product features a delightful 'Splash Lemon' fragrance, designed to uplift one’s mood, while its clear blue-green water adds a visually refreshing element to the bathing experience.
