Use water spray, carbon dioxide, dry chemical powder or appropriate foam
to extinguish fires.
Water May be used to keep exposed containers cool.
For large quantities involved in a fire, one should wear full protective clothing and a NIOSH approved
self contained breathing apparatus with full face piece operated in the pressure demand or positive
pressure mode as for a situation where lack of oxygen and excess heat are present.

Only selected registry of toxic effects of chemical substances (RTECS) data is presented here. See
actual entry in RTECS for complete information on lactic acid and glycerol.
Fatty Acids
Acute oral (rat) LD50 value for fatty acids is 10000 mg/kg. Aspiration of liquid may cause
pneumonitis. Repeated dermal contact may cause skin sensitization.
Section 6 — Health Hazard Data
One should anticipate the potential for eye irritation and skin irritation with large scale exposure or in
sensitive individuals. Product is not considered to be combustible. However, after prolonged contact
with highly porous materials in the presence of excess heat, this product may spontaneously combust.
Handling: Avoid continued contact with skin. Avoid contact with eyes.
In any case of any exposure which elicits a response, a physician should be consulted immediately.
First Aid Procedures
Inhalation:
Ingestion:
Remove to fresh air. If not breathing give artificial respiration. In case of
labored breathing give oxygen. Call a physician.
No effects expected. Do not give anything to an unconscious person. Call a

Regenesis — 3-D Microemulsion MSDS
physician immediately. DO NOT induce vomiting.
Section 6 — Health Hazard Data (cont)
Skin Contact:
Eye Contact:
Flush with plenty of water. Contaminated clothing may be washed or dry
cleaned normally.
Wash eyes with plenty of water for at least 15 minutes lifting both upper
and lower lids. Call a physician.
Section 7 — Reactivity Data
Conditions to Avoid: Strong oxidizing agents, bases and acids
Hazardous Will not occur.
Polymerization:
Further Information: Hydrolyses in water to form lactic acid, glycerol and fatty acids.
Hazardous Decomposition Thermal decomposition or combustion may produce carbon monoxide
Products: and/or carbon dioxide.
Section 8 — Spill, Leak or Accident Procedures
After Spillage or
Leakage:
Disposal:
Neutralization is not required. The material is very slippery. Spills should
be covered with an inert absorbent and then be placed in a container. Wash
area thoroughly with water. Repeat these steps if slipperiness remains.
Laws and regulations for disposal vary widely by locality. Observe all
applicable regulations and laws. This material may be disposed of in solid
waste. Material is readily degradable and hydrolyses in several hours.
No requirement for a reportable quantity (CERCLA) of a spill is known.
Section 9 — Special Protection or Handling
Should be stored in plastic lined steel, plastic, glass, aluminum, stainless steel, or reinforced fiberglass
containers.
Protective Gloves: Vinyl or Rubber
Eyes: Splash Goggles or Full Face Shield. Area should have approved means of
washing eyes.
Ventilation: General exhaust.
Storage: Store in cool, dry, ventilated area. Protect from incompatible materials.

Section 10 — Other Information
This material will degrade in the environment by hydrolysis to lactic acid, glycerol and fatty acids.
Materials containing reactive chemicals should be used only by personnel with appropriate chemical
training.
The information contained in this document is the best available to the supplier as of the time of
writing. Some possible hazards have been determined by analogy to similar classes of material. No
separate tests have been performed on the toxicity of this material. The items in this document are
subject to change and clarification as more information becomes available.
