8001-31-8 Usage
Description
Coconut oil is a semisolid, soft white or slightly yellow fat derived from the kernels of the coconut palm. It is composed primarily of short-chain fatty acids bonded with glycerine and is known for its stability when exposed to air.
Uses
Used in Cosmetics and Personal Care Industry:
Coconut oil is used as a cream base, raw material for soaps, ointments, massage creams, and in sunscreen formulations due to its semisolid consistency and emollient properties.
Used in Food Industry:
Coconut oil is used in confections, baked goods, and margarine. Its sharp melting character and narrow plastic range make it suitable for the preparation of shortenings where brittleness and a large change in consistency with a small temperature change are undesirable.
Used in Partially Hydrogenated Coconut Oil:
Partially hydrogenated coconut oil has hydrogen added to part of the unsaturated carbon bonds to provide a more solid consistency, making it suitable for various food applications.
However, it is important to note that coconut oil may be irritating to the skin and cause skin rashes, and it is also considered comedogenic.
Production Methods
Coconut oil is the fixed oil obtained from the seeds of Cocos
nucifera Linn. (Palmae). This oil is then refined to produce refined
coconut oil, which is referred to in the coconut industry as RBD
(refined, bleached, and deodorized) coconut oil.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Coconut oil react with acids to liberate heat. Heat is also generated by interaction with caustic solutions. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Flammable hydrogen is generated by mixing with alkali metals and hydrides. Reacts slowly with air to become rancid.
Health Hazard
Oil is essentially nontoxic, but can cause mild irritation of eyes on contact.
Pharmaceutical Applications
Coconut oil has traditionally been used in ointments where it forms
a readily absorbable base. It has been used particularly in
preparations intended for application to the scalp, where it could
be applied as a solid but would liquefy when applied to the skin.
Coconut oil is readily saponified by strong alkalis even in the cold
and, as the soap produced is not readily precipitated by sodium
chloride, it has been used in the making of ‘marine’ soap.
Coconut oil may be used in the formulation of a range of other
preparations including emulsions and nanoemulsions, intranasal
solutions, and rectal capsules and suppositories. In
addition, coconut oil has been reported to have antifungal activity
against a range of Candida species.
Coconut oil has been used therapeutically in a lotion for the
eradication of head lice, and was included in a regime used to
treat a patient who had ingested 16.8 g aluminum phosphide.
Concern has been expressed at the potential use of coconut oil as
a suntan lotion as it does not afford any protection against
ultraviolet light.
Safety
When administered orally, coconut oil is essentially nontoxic,
although ingestion of large amounts may cause digestive or
gastrointestinal irritation or upset. Coconut oil can act as an
irritant when applied to the skin and when in contact with the eyes;
it may be absorbed through the skin. Inhalation of mist or vapor
may cause respiratory tract irritation.
storage
Coconut oil remains edible, and mild in taste and odor, for several
years under ordinary storage conditions. However, on exposure to
air, the oil readily oxidizes and becomes rancid, acquiring an
unpleasant odor and strong acid taste.
Store in a tight, well-filled container, protected from light at a
temperature not exceeding 258℃. Coconut oil may be combustible
at high temperature, and may spontaneously heat and ignite if
stored under hot and wet conditions.
Incompatibilities
Coconut oil reacts with oxidizing agents, acids and alkalis.
Polyethylene is readily permeable to coconut oil.
It has been shown that the increased force required to expel
coconut oil from plastic syringes was due to uptake of the oil into
the rubber plunger; this resulted in swelling of the rubber plunger
and an increased resistance to movement down the syringe
barrel.
Regulatory Status
Included in the FDA Inactive Ingredients Database (oral capsules
and tablets; topical creams, solutions, and ointments). Included in
scalp ointments and therapeutic shampoos licensed in the UK.
Check Digit Verification of cas no
The CAS Registry Mumber 8001-31-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,0 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 8001-31:
(6*8)+(5*0)+(4*0)+(3*1)+(2*3)+(1*1)=58
58 % 10 = 8
So 8001-31-8 is a valid CAS Registry Number.
