Zinc stearate is a “zinc soap” that is widely used industrially. In this context, soap is used in its formal sense, a metal “salt” of a fatty acid. It is a white solid that repels water. It is insoluble in polar solvents such as alcohol and ether but soluble in aromatic hydrocarbons (e.g., benzene) and chlorinated hydrocarbons when heated. It is the most powerful mold release agent among all metal soaps. It contains no electrolyte and has a hydrophobic effect. Its main application areas are the plastics and rubber industry, where it is used as a releasing agent and lubricant which can be easily incorporated.

Accidental Release Measures
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material’s impact on air quality; potential migration in soil or water; effects on animal and plant life; and conformance with environmental and public health regulations.
The substances listed in paragraph (b) of this section may be safely used as antioxidants and/or stabilizers in polymers used in the manufacture of articles or components of articles intended for use in producing, manufacturing, packing, processing, preparing, treating, packaging, transporting, or holding food, subject to the provisions of this section: (a) The quantity used shall not exceed the amount reasonably required to accomplish the intended technical effect. Zinc stearate is included on this list.

Environmental Fate/Exposure Summary
Androstenedione’s production and administration as a drug to treat symptoms due to male andropause, dietary supplement, and athletic performance-enhancing drug may result in its release to the environment through various waste streams. Androstenedione is a naturally occurring androgen produced by the adrenal gland and converted to testosterone or estrone. It is produced naturally in humans during the production of testosterone and estrogen. It can be formed in soils via the metabolism of testosterone and estradiol occurring in poultry and livestock manures used as agricultural fertilizers. If released to air an extrapolated vapor pressure of 7.35X10-9 mm Hg at 20 °C indicates androstenedione will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase androstenedione will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and with ozone; the half-lives for these reactions in the air are estimated to be 3.5 hours and 1 day respectively. Particulate-phase androstenedione will be removed from the atmosphere by wet and dry deposition. Androstenedione absorbs light at wavelengths >290 nm, and therefore, may be susceptible to direct photolysis. If released to soil, androstenedione is expected to have no mobility based upon a Koc of 6170. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry’s Law constant of 3.7X10-8 atm-cu m/mole. Androstenedione is not expected to volatilize from dry soil surfaces based upon its vapor pressure. Results of soil column studies using various soils and sands found that half-life of androstenedione ranged from 1.7 to 77 hours. If released into water, androstenedione is expected to adsorb to suspended solids and sediment based upon the Koc. Using OECD Guideline 301B (CO2 Evolution Test), androstenedione reached 79-95% degradation over a 28-day incubation period which classified the compound as readily biodegradable. Volatilization from water surfaces is not expected to be an important fate process based upon this compound’s estimated Henry’s Law constant. An estimated BCF of 30 suggests the potential for bioconcentration in aquatic organisms is low to moderate. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. Androstenedione in aqueous solutions underwent direct photolysis half-lives ranging from 3.7 to 10.8 hours in direct sunlight. Occupational exposure to androstenedione may occur through dermal contact with this compound at workplaces where androstenedione is produced or used.
