Chemical and Environmental


Aerosol Disposal

CAP-STUN® aerosol primary ingredients are biodegradable and not a hazard to the environment. Large quantities of empty aerosol canisters of CAP-STUN® products can be disposed of by whatever locally accepted means of discarding aluminum products, or by forwarding the empty units to a local aluminum or steel recycling facility.

Large amounts of filled aerosol canisters of CAP-STUN® products should be forwarded to a local facility equipped to incinerate pressurized aerosols or disposed of by whatever locally accepted means for disposing pressurized aerosol canisters.

Removing CAP-STUN® Formula From Clothing

CAP-STUN® ingredients are biodegradable and soluble in standard (regular) detergents or dry cleaning chemicals.

Uniforms, clothing or fabrics contaminated with CAP-STUN® formula will be removed by using standard detergents or dry cleaning chemicals.

Isopropyl Alcohol

  • Unlike water, it is highly effective as an OC carrier. It does not impede the effectiveness of the active ingredient.
  • Because of its high safety level, it is used in a majority of household aerosols.
  • Isopropyl Alcohol, not refrigeration agents, is used in virtually all aerosol products intended to be sprayed in the facial area such as perfumes and after-shaves.
  • It is used for many medical purposes and is found in all hospitals.
  • Isopropyl Alcohol is evironmentally safe and not banned by the Montreal Protocol as an ozone depleting substance. This is not the case with the carrier used in some of the clones.
  • It is not a cancer causing agent. Isopropyl Alcohol is not listed under California’s Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65) as a carcinogen, reproductive toxicant nor listed under USEPA nor IARC as a cancer causing or potential carcinogen agent. Again, this is not the case with the carrier used in some of the clones.

Not All Alcohols are Safe

There are variety of alcohols which are used in the medical industry as well as components in the solvent system of coatings for many industrial applications. For example methanol alcohol is toxic and can cause blindness. SDA-40B alcohol is used in some pepper sprays and is listed under California Proposition 65, since it contains trace levels of acetaldehyde, which the state of California has found to cause cancer.

High Pressure Liquid Chromatography (HPLC)

Purpose: To determine pungency levels in capsicums and their oleoresins.
A. Apparatus: 

  1. High pressure liquid chromatograph, pump flow rate (0.6 to 1.8 ml/min).
  2. Detector
  1. UV at 280 nm, flow cell path (1 x 10 mm), greater than 700 ppm capsaicin.
  2. Fluorescence at 288 excitation, 320 emission, flow cell path of 10 x 1 micron, less than 700 ppm capsaicin.
  1. Column: C18, 10 micron spherical, 4.6 mm x250 mm.
  2. Rheodyne syringe loading sample injector with 20 microliter loop.
  3. 100 ml volumetric flask.

B. Reagents:

  1. Acetonitrile, HPLC grade.Dioxane, HPLC grade.HPLC grade water.HPLC grade methanol.2% perchloric acid.95% ethanol, saturated with sodium acetate.HPLC grade sodium acetate.
  2. Capsaicin. (Pharmaceutical quality).

C. Procedure:

  1.  Weigh sample into 100 ml. volumetric flask:
    1. 10.00 g for pungencies from 0 to 1000 ASTA Heat Units1.00 g for pungencies from 1,000 to 10,000 ASTA Heat Units
    2. 0.10 g for pungencies greater than 10,000 ASTA Heat Units
    Bring to 100 ml. with 95% ethanol saturated with sodium acetate.Cap and place on hot plate at 60 C or water bath for three hours, swirling occasionally.Swirl and allow solids to settle.Fill sample loop and elute with a mix* of: 48.4% methanol, 30.2% HPLC grade water, 13.3% dioxane, 7.9% acetonitrile, 0.2% of 2% perchloric acid.The first peak is the pigment peak, the second peak is capsaicin, the third peak is capsaicinoid.
  2. Prepare capsaicin standards at 0.01, 0.10, 1.0 mg./ml. (label 10, 100 and 1,000 ppm capsaicin) in 95% ethanol, saturated with sodium acetate.

*For low pungency capsicums (less than 700 ppm capsaicin):

  1. Prepare solvent mixture A (5.4% acetonitrile, 3.6% dioxane, 0.7% perchloric acid, 90.3% water) and B (9.0% acetonitrile, 18.0% dioxane, 73.0% methanol).
  2. Program gradient separation: At 0 min. (0% solvent B); at 2.5 min. (increase B from 0 to 60% in 5 min.); 7.5 to 12.5 min. (isocratic at 60%); 12.5 min. (60% to 100% B).

Calculation:  

  1. Total capsaicin area=Area peak 2+.82 Area peak 3.

    Capsaicin (ppm) = Total capsaicin area of sample x ppm standard x 100 / Total capsaicin area of standard xg.

    Sample ASTA Pungency=ppm capsaicin

  2. Pungency (Scoville) =ppm capsaicin x 15 (assume Capsaicin standard at 15,000,000 Scoville)

ppm capsaicin x 15 = Scoville units (assumes capsaicin = 15,000,000 Scoville)
