Frequently Asked Questions
What chemical transformation occurs during the production of castor wax?
Refined castor oil is reacted with molecular hydrogen over a nickel catalyst to saturate all double bonds, creating tri-hydroxystearin wax with melting point 85–88°C.
What physical parameters define NDEVWAX™ HCO flakes?
Sharp melting point of 85°C to 88°C, iodine value under 3.0 g I2/100g, acid value below 3.0 mg KOH/g, and hydroxyl value of 155 to 165.
What physical forms are available for hydrogenated castor oil?
Supplied as flakes or micronized powder as specified per order, packaged in 25 kg bags with inner poly liner or 500/1000 kg bulk bags.
How are HCO wax flakes protected during ocean transport?
Packaged in 25 kg multi-wall paper sacks with inner polyethylene moisture barriers or 500/1000 kg PP jumbo bags. Container payloads in a 20ft FCL are typically 16–18 MT palletized and stretch-wrapped, or 20 MT loose floor-stuffed.
What is the difference in chemical structure between HCO and hydroxylated fatty acids?
HCO is a complete triglyceride wax ester containing glycerin, whereas 12-HSA is a split, isolated free fatty acid used directly in soap making.
