Overview
HEDP ACID chemical name is Hydroxy Ethylidene -1,1-Diphosphonic acid manufacturer, supplier and exporter. HEDP is organophosphonate compound which have chemical properties of sequestration, deflocculation, threshold inhibition and hydrolytic stability etc. HEDP is an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds. It can dissolve the oxidized materials on these metals’ surfaces.

3. (b) HAZARDS – TOXICITY:
Effects, Acute Exposure:
| Skin Contact | Irritating, may be corrosive if not removed promptly |
| Skin Absorption | Slight; no toxic effects likely by this route |
| Eye Contact | Irritating, may be corrosive if not removed promptly |
| Inhalation | Product mist is irritating; prolonged exposure may be corrosive to respiratory tract |
| Ingestion | Irritating to mouth, throat & stomach – not a route of industrial exposure |
Effects, Chronic Exposure:
| General | Chronic ingestion of HEDP binds to bone, reducing mineralization of bone in adult beagles & in young rats giving rise to less calcium (& presumably strength) in bone |
| Sensitising | Not a sensitiser in humans or animals |
| Carcinogen/Tumorigen | Not considered a tumorigen or a carcinogen in humans or animals |
| Reproductive Effect | Reduced fertility in rats on prolonged ingestion; no known effect in humans |
| Mutagen | No known effect on humans or animals; some mutagenic effect observed in onion & barley root tips – significance of this to human health is not known |
| Synergistic With | Not known |
| LD50 (oral) | 2400, 3130 & 3550mg/kg (rat) |
| LD50 (skin) | >7940mg/kg (rabbit), >10,000mg/kg (rabbit) |
| LC50 (inhalation) | Not known |
| SKIN: | Wash with plenty of water. Remove contaminated clothing and do not reuse until thoroughly laundered. |
| EYES: | Wash eyes with plenty of water, holding eyelids open. Seek medical assistance promptly if there is irritation. |
| INHALATION: | Remove from contaminated area promptly. CAUTION: Rescuer must not endanger himself! If breathing stops, administer artificial respiration and seek medical aid promptly. |
| INGESTION: | Give plenty of water to dilute product, or milk if available to neutralise it. Do not induce vomiting (NOTE below). Keep victim quiet. If vomiting occurs, lower victim’s head below hips to prevent inhalation of vomited material. Seek medical help promptly. |
| Inadvertent inhalation of vomited material may seriously damage the lungs. The danger of this is greater than the risk of poisoning through absorption of this relatively low-toxicity substance. The stomach should only be emptied under medical supervision, and after the installation of an airway to protect the lungs. |
| Flash Point | Not known – will not flash |
| Autoignition Temperature | Not known – will not burn |
| Flammable Limits | Not known – will not burn |
| Combustion Products | Nitrogen oxides, phosphorous oxides |
| Firefighting Precautions | As for materials sustaining fire; firefighters must wear SCBA |
| Static Charge Accumulation | Cannot accumulate a static charge on agitation or pumping |
| Leak Precaution dyke to control spillage and prevent environmental contamination Handling Spill ventilate contaminated area; recover free liquid with suitable corrosion resistant pumps; absorb residue on an inert sorbent, sweep, shovel, & store in closed containers for recycling or disposal |
