Dear Dymel Customer:
It has come to our attention that makers of personal safety devices may be using HCFC
in the formulation of pepper sprays for self defense. It is also our understanding that
the instructions for use of these pepper spray products may require direct spraying of the
product into the eyes and other facial areas.
Attached is a current copy of our MSDS on Dymel 22 propellant. Please note that this
MSDS states that no eye or skin irritation testing has been performed with this compound.
While we are not sure of the exact amount, if any, of Dymel 22 that is actually reaching
the facial area, there exists the potential for an unsafe situation. We hereby request
that you closely follow the guidelines for safe use of Dymel 22 established in our
Material Safety Data Sheet.
Sincerely,
Donald P. Dunn

CONSUMER ALERTDuPont Cautions Against Use of
HCFC Dymel in Pepper Sprays
August 20, 1993Attached please find a statement from DuPont Chemicals, dated July 14, 1993, cautioning
against the use of HCFC as a propellant in aerosol self protection devices and less lethal
tear gas type products such as pepper sprays. Dymel is not intended for use in products
meant to be sprayed into the face or to come into contact with skin or eyes.Please note the following excerpts from DuPont Chemical's Material Safety Data Sheet
- MSDS (2002FR Revised 26-Aug-91) on Dymel 22:
- " TITLE III HAZARD CLASSIFICATION: Toxic Chemical YES""The compound is untested for skin and eye irritancy, and is untested for animal
sensitization".
- " Avoid breathing vapors and liquid contact with skin or eyes."
Additionally HCFCs, including Dymel 22, are ozone depleters and are regulated and being
banned by the international Montreal Protocol agreement. Decrease in ozone level
translates to increased penetration of harmful ultraviolet rays. In turn, the increase of
ultraviolet rays leads to higher incidence of skin cancer and cataracts, damage to the
immune system, lower crop yield, and disruption of the aquatic food chain.Your organization should identify products containing Dymel and take into account the
health and safety impact of the different propellants available in pepper sprays by
obtaining MSDS's on various ingredients within the aerosol.Zarc International, Inc.
