4070-80-8 Usage
Description
Sodium Stearyl Fumarate (SSF) is used as a lubricant in tableting to reduce the friction between the tablet and the die wall and to prevent adhesion of the material to punches or the die wall in the pharmaceutical industries. It is used also as a lubricant in the manufacturing of capsules and other oral dosage forms. Sodium stearyl fumarate is also used in food production as a dough conditioner, a conditioning agent, and a stabilizing agent.
Chemical Properties
Sodium stearyl fumarate is a fine, white powder with agglomerates
of flat, circular-shaped particles.
Uses
Different sources of media describe the Uses of 4070-80-8 differently. You can refer to the following data:
1. Sodium Stearyl Fumarate is a dough conditioner and conditioning agent that is a white powder practically insoluble in water. It is used as a dough conditioner in yeast-raised baked goods. It is used as a conditioning agent in dehydrated potatoes. It also functions as a maturing and bleaching agent.
2. cationic transfection agent, bile acid sequestrant, vaccine adjuvant, protein stabilizer
3. Binder
Production Methods
Stearyl alcohol is reacted with maleic anhydride. The product of this
reaction then undergoes an isomerization step followed by salt
formation to produce sodium stearyl fumarate.
Pharmaceutical Applications
Sodium stearyl fumarate is used as a lubricant in capsule and tablet
formulations at 0.5–2.0% w/w concentration. It is also used in
certain food applications.
Safety
Sodium stearyl fumarate is used in oral pharmaceutical formulations
and is generally regarded as a nontoxic and nonirritant
material.
Metabolic studies of sodium stearyl fumarate in the rat and dog
indicated that approximately 80% was absorbed and 35% was
rapidly metabolized. The fraction absorbed was hydrolyzed to stearyl alcohol and fumaric acid, with the stearyl alcohol further
oxidized to stearic acid. In the dog, sodium stearyl fumarate that
was not absorbed was excreted unchanged in the feces within 24
hours.
Stearyl alcohol and stearic acid are naturally occurring
constituents in various food products, while fumaric acid is a
normal constituent of body tissue. Stearates and stearyl citrate have
been reviewed by the WHO and an acceptable daily intake for
stearyl citrate has been set at up to 50 mg/kg body-weight. The
establishment of an acceptable daily intake for stearates and
fumaric acid was thought unnecessary.
Disodium fumarate has been reported to have a toxicity not
greatly exceeding that of sodium chloride.
storage
At ambient temperature, sodium stearyl fumarate is stable for up to
3 years when stored in amber glass bottles with polyethylene screw
caps.
The bulk material should be stored in a well-closed container in a
cool, dry place.
Incompatibilities
Sodium stearyl fumarate is reported to be incompatible with
chlorhexidine acetate.
Regulatory Status
GRAS listed. Permitted by the FDA for direct addition to food for
human consumption as a conditioning or stabilizing agent in
various bakery products, flour-thickened foods, dehydrated potatoes,
and processed cereals up to 0.2–1.0% by weight of the food.
Included in nonparenteral medicines licensed in the UK. Included in
the FDA Inactive Ingredients Database (oral capsules and tablets).
Included in the Canadian List of Acceptable Non-medicinal
Ingredients.

Check Digit Verification of cas no
The CAS Registry Mumber 4070-80-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,7 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4070-80:
(6*4)+(5*0)+(4*7)+(3*0)+(2*8)+(1*0)=68
68 % 10 = 8
So 4070-80-8 is a valid CAS Registry Number.
