Since there is a tendency, a comparison was made regarding the separation stability at 40 ° C. Test method: 100 ml graduated cylinder (height approx. 25
(cm) A 100 ml sample was placed and stored at 40 ° C., and the change in appearance (the period until the water layer was separated by 5% or more) was used as a measure of the separation stability.
