N/A = Not applicable                                                                                                                       N/D = Not determined

                                               SECTION I: HAZARDOUS INGREDIENTS/HEALTH HAZARD DATA

This product has not been tested as a whole for health effects on animals or humans. According to the OSHA Hazardous Communications Standard (29 CFR

1910.1200) any hazardous ingredients that comprise >1.0% of the material and any carcinogenic ingredients that comprise >0.1% must be listed on the MSDS.



SECTION I (a): List of carcinogenic ingredients at >0.1%.

NAME                                                                          CAS NO.

TRISODIUM NITRILOTRIACETATE                                                   18662-53-8

May cause eye and skin irritation. Oral rat LD50 is 1450 mg/kg; dermal rabbit LD50 is > 10, 000 mg/kg. Listed as a possible carcinogen by IARC and NTP. OSHA

PEL and ACGIH TLV not available. Detergents containing Sodium Nitrilotriacetate are exempt from labeling under California Proposition 65 because exposure in

detergent applications are significantly less than the "NO SIGNIFICANT RISK LEVEL" established by Cal-EPA for this compound. The Universities Associated for

Research and Education in Pathology, Inc. determined that the cancer risk to man was so low `one in ten million or less' as to be of no practical significance. Thus

UAREP concluded that `use of NTA in detergent products does not pose a practical risk to human health.'



SECTION I (b): List of hazardous ingredients at >1.0%.

NAME                                                                      CAS NO.

SODIUM DODECYL DIPHENYLOXIDE DISULFONATE                                  119345-04-9

May cause corneal damage, permanent impairment of vision, even blindness. Single dose oral toxicity is low. Oral rat LD50>2000 mg/kg.

LD50 for skin absorption in rabbits is >2000 mg/kg. OSHA PEL and ACGIH TLV not available.
