Our line of bath additives, Bub, uses CO2 gas to heighten the effect of hot bath water in promoting blood circulation and relieving such symptoms as chronic cold, fatigue, and stiff shoulders. The gas helps to expand peripheral blood vessels. Because we know that the amount of blood flowing through the skin depends in part on the concentration of CO2 gas absorbed from the skin, we searched for substances that heighten CO2 gas absorption and discovered a special type of oil-based constituent.
We have developed technologies to adapt this functional oil-based constituent for use in bath additives, one of which is Bub Rich.
