Description:

WARNING: This product is for research use only, not for human or veterinary use.

Ricinoleic acid is a fatty acid. It constitutes about 90% of the fatty acids in castor oil. Ricinoleic acid can serve as a substrate for the synthesis of conjugated linoleic acids. It is considered safe and non-toxic as a food constituent in humans, up to a daily intake of 2.5 grams per day. In high doses, castor oil has a laxative effect.

Product Data
Biological target:
L-Ribulose is an isomer of L-ribose.
In vitro activity:
The results from the in vitro study showed that the blank ricinoleic acid pluronic lecithin organogel (PLO) gel possessed significantly higher anti-inflammatory activity than isopropyl palmitate PLO gel. Both the gel formulations had no significant cytotoxic activity. Reference: Mediators Inflamm. 2000;9(5):223-8. https://pubmed.ncbi.nlm.nih.gov/11200362/
In vivo activity:
Ricinoleic acid and capsaicin given for 1-3 weeks reduced inflammation induced by intradermal injection of carrageenan in the mouse or by histamine in the guinea-pig eyelid. Ricinoleic acid may be seen as a new capsaicin-like, non-pungent anti-inflammatory agent suitable for peripheral application.
