Transdermal Absorption of Castor Oil
With the current high level of interest in patches to deliver drugs across the skin, the concept of external applications for delivery of medicinal substances is becoming widely accepted. This study evaluated the potential for transdermal absorption of castor oil, a treatment modality recommended by Edgar Cayce. Specific epoxydicarboxylic acids are known to be excreted via the urine when castor...
متن کاملNonlinear optical properties of castor oil
We report on the investigation of the nonlinear optical properties of castor oil using the Z-scan technique. Nonlinear refraction and absorption measurements were performed for two different laser wavelengths, 514 and 810 nm, in the CW regime, and for 810 nm in femtosecond regime. The CW results showed that castor oil has a large negative nonlinear refractive index n2 = -3.2 x 10 cm/W for the l...
متن کاملBiochemical aspects of castor oil biosynthesis.
Castor oil is 90% ricinoleate (12-hydroxy-oleate) and has numerous industrial uses. Components of castor bean (Ricinus communis L.) pose serious problems to processors. We are evaluating two complementary approaches to providing a safe source of castor oil.
متن کاملBiodegradation of Polyurethane Derived from Castor Oil
The aim of this research was to study the biodegradation of a polymer derived from castor oil, which is a renewable, natural material that is a practical alternative for the replacement of traditional polyurethane foams. Due to its molecular structure, which contains polyester segments derived from vegetable oil, the polymeric surface is susceptible to microorganism attack. This study tested th...
متن کاملThe Enzymology of Castor Oil Biosynthesis
The castor plant Ricinus communis L., Euphorbiaceae produces seeds containing a unique oil. Castor oil is the only commodity vegetable oil that contains significant amounts of hydroxy fatty acid. This fatty acid is ricinoleic acid (12-hydroxy oleic acid) (Fig. 1) and it comprises up to 90% of the total fatty acid (FA) content of castor oil. Due to the physical and chemical properties imparted b...
