Definition
A complex containing aluminum and dextran, a chain of molecular weight 2500, corresponding to a chain of 15 anhydroglucose units.
Production Methods
Aluminum monostearate is prepared by reacting aluminum with
stearic acid.
Pharmaceutical Applications
Aluminum monostearate is mainly used in microencapsulation
and in the manufacture of ointments. Aluminum monostearate is
used as a viscosity-increasing agent in nonaqueous cosmetic and
pharmaceutical formulations. In addition, aluminum monostearate
can be used as an emulsion stabilizer in cosmetic emulsions and is
used in cosmetics such as mascara, moisturizers, and sunscreens.
Safety Profile
A nuisance dust. When heated to decomposition it emits acrid smoke and fumes. See also ALUMINUM COMPOUNDS.
Safety
Aluminum monostearate is generally regarded as relatively nontoxic
and nonirritant when used as an excipient.
storage
Aluminum monostearate should be stored in a well-closed container
in a cool, dry, place. It is stable under ordinary conditions of use and
storage.
Regulatory Status
Aluminum monostearate and aluminum stearate are included in the
FDA Inactive Ingredients Database (oral capsules and tablets,
topical creams and ointments). Included in nonparenteral medicines
licensed in the UK.
Check Digit Verification of cas no
The CAS Registry Mumber 7047-84-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,4 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7047-84:
(6*7)+(5*0)+(4*4)+(3*7)+(2*8)+(1*4)=99
99 % 10 = 9
So 7047-84-9 is a valid CAS Registry Number.
