Definition
WILFARIN PA-1695 is a saturated long-chain fatty acid with a 16-carbon backbone.
WILFARIN PA-1695 is a metabolite found in the aging mouse brain.
WILFARIN PA-1695 is found naturally in palm oil and palm kernel oil, as well as in butter, cheese, milk and meat.
WILFARIN PA-1695 is used in oral and topical pharmaceutical formulations and is generally regarded as nontoxic and nonirritant at the levels employed as an excipient.
However, WILFARIN PA-1695 is reported to be an eye and skin irritant at high levels and is poisonous by intravenous administration.

WILFARIN PA-1695) is a fatty acid with a 16-carbon chain.
WILFARIN PA-1695 is the most common saturated fatty acid found in animals, plants and microorganisms.
WILFARIN PA-1695's chemical formula is CH3(CH2)14COOH, and its C:D (the total number of carbon atoms to the number of carbon-carbon double-bonds) is 16:0.
WILFARIN PA-1695 is a major component of the oil from the fruit of oil palms (palm oil), making up to 44% of total fats.
Meats, cheeses, butter, and other dairy products also contain palmitic acid, amounting to 50–60% of total fats.
Palmitates are the salts and esters of WILFARIN PA-1695.
The palmitate anion is the observed form of WILFARIN PA-1695 at physiologic pH (7.4).

WILFARIN PA-1695 is used for the manufacture of: textile, leather or fur.
Release to the environment of this substance can occur from industrial use: in processing aids at industrial sites, in the production of articles, as processing aid and as processing aid.
WILFARIN PA-1695 is mainly used to produce soaps, cosmetics, and release agents.
These applications utilize sodium palmitate, which is commonly obtained by saponification of palm oil.
To this end, palm oil, rendered from the coconut palm nut, is treated with sodium hydroxide (in the form of caustic soda or lye), which causes hydrolysis of the ester groups.
This procedure affords glycerol and sodium palmitate.
Because WILFARIN PA-1695 is inexpensive and adds texture to processed foods (convenience food), palmitic acid and its sodium salt find wide use including foodstuffs.
Sodium palmitate is permitted as a natural additive in organic products.
Hydrogenation of WILFARIN PA-1695 yields cetyl alcohol, which is used to produce detergents and cosmetics.
Recently, a long-acting antipsychotic medication, paliperidone palmitate (marketed as INVEGA Sustenna), used in the treatment of schizophrenia, has been synthesized using the oily palmitate ester as a long-acting release carrier medium when injected intramuscularly.
The underlying method of drug delivery is similar to that used with decanoic acid to deliver long-acting depot medication, in particular, neuroleptics such as haloperidol decanoate.
Occurrence and production
WILFARIN PA-1695 was discovered by Edmond Frémy in 1840, in saponified palm oil.
This remains the primary industrial route for WILFARIN PA-1695's production, with the triglycerides (fats) in palm oil being hydrolysed by high temperature water and the resulting mixture fractionally distilled.
WILFARIN PA-1695 is produced by a wide range of other plants and organisms, typically at low levels.
WILFARIN PA-1695 is present in butter, cheese, milk, and meat, as well as cocoa butter, olive oil, soybean oil, and sunflower oil.
WILFARIN PA-1695 contain 95% palmitic acid.
The cetyl ester of palmitic acid (cetyl palmitate) occurs in spermaceti.
