Size: 180 ~ 200mgKOH / g. Naphthenate light color, tasteless, with viscosity, high purity.
Refined degreased Naphthenic Acid
Refined petroleum products were isolated when the organic acid, the original dark brown oily mixture of refined yellow to light yellow or light brown transparent oily liquid with special smell. The advantages of light color products, water content is small, high-acid crude, free fatty acids, viscosity.
