8015-86-9 Usage
Uses
Used in Automobile Industry:
Carnauba wax is used as a hard, high-polish wax for automobile waxes, providing a durable and shiny finish to car surfaces.
Used in Floor Wax Industry:
Carnauba wax is used in floor wax emulsions, offering a high-polish and durable finish for flooring.
Used in Shoe Polish Industry:
Carnauba wax is used in high-quality shoe polishes, providing a hard, high-polish finish to shoes.
Used in Paper Industry:
Carnauba wax is used in the paper industry, especially for making carbon papers, due to its high hardness and durability.
Used in Dental Industry:
Carnauba wax is used as a plasticizer in dental impression compounds, providing a firm and stable impression for dental applications.
Used in Cosmetic Industry:
Carnauba wax is used to firm and texturize cosmetic preparations, giving them a less fluid consistency and forming a protective layer on the skin's surface. It is also used in depilatories and deodorant sticks.
Used in Pharmaceutical Industry:
Carnauba wax is used in the final stage of tablet coating in the pharmaceutical industry, providing a smooth and polished finish to tablets.
Used in Food Industry:
Carnauba wax is a general-purpose food additive, used in candy glazes due to its hard and brittle properties.
Overall, Carnauba wax is a versatile and valuable natural resource with a wide range of applications in various industries, from automotive and floor waxes to cosmetics and pharmaceuticals. Its unique properties, such as high hardness, high melting point, and low allergenicity, make it an ideal choice for many applications where a hard, high-polish wax is desired.
Production Methods
Carnauba wax is obtained from the leaf buds and leaves of the
Brazilian carnauba palm, Copernicia cerifera. The leaves are dried
and shredded, and the wax is then removed by the addition of hot
water.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Carnauba wax 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.
Health Hazard
Hot wax can burn skin and eyes.
Pharmaceutical Applications
Carnauba wax is widely used in cosmetics, certain foods, and
pharmaceutical formulations. Cosmetically, carnauba wax is
commonly used in lip balms.
Carnauba wax is the hardest and highest-melting of the waxes
commonly used in pharmaceutical formulations and is used
primarily as a 10% w/v aqueous emulsion to polish sugar-coated
tablets. Aqueous emulsions may be prepared by mixing carnauba
wax with an ethanolamine compound and oleic acid. The carnauba
wax coating produces tablets of good luster without rubbing.
Carnauba wax may also be used in powder form to polish sugarcoated
tablets.
Carnauba wax (10–50% w/w) is also used alone or with other
excipients such as hypromellose, hydroxypropyl cellulose, alginate/
pectin-gelatin, Eudragit, and stearyl alcohol to produce sustainedrelease
solid-dosage formulations.
Carnauba wax has been experimentally investigated for use in
producing microparticles in a novel hot air coating (HAC) process
developed as an alternative to conventional spray-congealing
techniques.(11) In addition, carnauba wax has been used to produce
gel beads for intragastric floating drug delivery and has been
investigated for use in nanoparticulate sunscreen formulations.
Safety
Carnauba wax is widely used in oral pharmaceutical formulations,
cosmetics, and certain food products. It is generally regarded as an
essentially nontoxic and nonirritant material. However, there
have been reports of allergic contact dermatitis from carnauba wax
in mascara.
The WHO has established an acceptable daily intake of up to 7
mg/kg body-weight for carnauba wax.
storage
Carnauba wax is stable and should be stored in a well-closed
container, in a cool, dry place.
Check Digit Verification of cas no
The CAS Registry Mumber 8015-86-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,1 and 5 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 8015-86:
(6*8)+(5*0)+(4*1)+(3*5)+(2*8)+(1*6)=89
89 % 10 = 9
So 8015-86-9 is a valid CAS Registry Number.
