Product introduction 
      Vertellus offers various grades of castor oil products, the use of which depends on the product's acidity value, moisture content, color and purity.
Because castor oil contains polar hydroxyl groups, it is compatible with a wide range of natural and synthetic resins, waxes, polymers and elastomers, and can be plasticized into all of the above. At the same time, castor oil also has good softening and lubricating properties, as well as remarkable wetting and dispersing dyes, pigments and fillers.
There are various chemical derivatives of castor oil, which make it more widely used. The ester bonds, double bonds and hydroxyl groups in castor oil molecules provide reactive sites for the formation of various beneficial derivatives.
Castor oil is a natural, non-toxic, biodegradable and renewable resource. Scientific and historical records show that castor oil from various sources has a very uniform chemical nature and composition. Typical values ​​in Table 2 apply to the grades of refined castor oil in Table 1.

Grade Description
The #1 imported oil is the lowest refined industrial grade castor oil. It is used in industries where moisture content and clarity are not critical.
AA® Standard Grade is a high-purity industrial castor oil. It is specifically used in reactions requiring low color, low acidity, and low moisture.
AA® USP grade castor oil does not contain impurities and spoilage substances, and also maintains the typical castor oil odor, flat odor, and meets the requirements of the cosmetic and pharmaceutical industries. AA® USP grade meets USP requirements.
Crystal® Crown is a refined castor oil containing antioxidants that is odorless, tasteless, light in color and highly transparent. Crystal® Crown complies with the Cosmetics, Cosmetics, Fragrance Association standards for castor oil.
Crystal® O is a refined castor oil that is free of antioxidants, odorless, tasteless, light in color and highly transparent. Crystal® O meets the requirements of the US Pharmacopeia and the CTFA standard for castor oil.
Crystal® LC is a refined castor oil that meets the requirements of the US Pharmacopeia. Crystal® LC is a light-colored viscous liquid with a molecular weight of 928. 90% of the main ingredients (approximately) are triglycerides of ricinoleic acid.
An ultra-grey grade is a lighter color, slightly higher acidity, and higher water content castor oil.
Filtered neutral oil castor oil has a very low acidity value.
DB® refined oils are the highest grade of castor oil. It is designed for critical uses with low acidity and moisture content in one place. DB® Oil is an ideal product for applications where a liquid such as sonar, liquid dielectrics and polyurethane reacts.
