All Cross-Linked Polyacrylamide has a very small amount of residual acrylamide left over from the manufacturing process. To put acrylamide exposure into perspective, rather large amounts of acrylamide are formed (from glucose and amino acids found commonly in many foods) when cooking foods at high heat (275 degrees Fahrenheit - frying, baking temperatures). Since the discovery of fire, it turns out humans have been ingesting acrylamide, without apparent harm (no observed toxicity). In modern life, acrylamide sources we commonly come into contact with include baby diapers, cigarette smoke, cosmetics, contact lenses, to name a few. Combined with ingested food exposure, the amount of acrylamide humans daily absorb is a number of orders of magnitude greater than you will ever come into contact with handling or using Hydrosource CLP with garden-raised foods. We routinely field questions about safety and proper handling. Since safety issues and our customer's peace of mind are paramount, we commissioned this updated MSDS by Marty LaBenz, a noted chemist and regulatory affairs specialist.

Please Note: Our MSDS does not apply to non Hydrosource cross-linked polymer products you may find being sold on the internet. Each CLP product has its own safety and handling issues. The various CLPs available in the marketplace are not all manufactured by the same company. Unfortunately, many of our competitors are too lazy or too stupid to get or create their own MSDS for their products. Instead, they steal a copy of our MSDS and are sloppy enough to not remove our contact information from the document before placing it on their own website. This almost goes without saying, but you should be careful who you do business with, especially on the internet.
Also Note: ALL chemicals and substances - EVERYTHING - in the world is toxic if you come into contact with too much, too quickly. Too much oxygen, you die. Too much water too fast, you die. Car intersecting wall too quickly, you die. There is no such thing in this world as "NON-TOXIC". Any company that labels their product as 'non-toxic' is either ignorant of the facts of life, or they are intentionally lying to you. Be very suspicious of anyone selling 'non-toxic'. Instead, the question to always ask is: Is this chemical or product safe when used as specified or directed?
Hydrosource CLP is very safe when used in agriculture for raising food, and when handled as directed. Hydrosource CLP is many times more safe than the food you eat, and the cosmetics and cigarette smoke you come in contact with, regularly.

Let me introduce myself. My name is Dale Greenwood. I am the president of Castle International Resources, and I've owned and operated this website since its inception fourteen years ago. When Dan Wofford (our founder) passed away in October 1998, he willed that I continue his efforts in the Hydrosource polymer business.
I have actively worked in the research & development of cross-linked polyacrylamide in agriculture since the early 1980's. The use of landscape fabric with polymer was my invention. I built Dan Wofford's computers, set-up and operated the original electronic bulletin board (pre-Internet), set-up and operated this website, and handled the technical details of Dan's communications systems until his untimely death.
Nearly eleven years down the line, the Hydrosource trademark dispute with Dan's third wife, Nita Jacobs, has been resolved. All claims to the original Hydrosource business are settled. I plan to aggressively re-establish the Hydrosource brand name in the marketplace.
- Many new technical articles will be published along with a simplified set of directions.
- Our Quality Assurance CLP lab-testing program will include test results for: evapo-transpirative rates, free monomer, hydration performance, UV-resistance, freeze/thaw resistance, heat resistance, ion/hydration impairment studies, rate of hydration, rate of desiccation and weight stability with respect to moisture, among others.
- Hundreds of websites and page links will be presented in a library of gardening and agricultural know-how, with special editorial articles. Most of the original BBS articles and photos will be added to the website. Current research efforts will be published.
- New agricultural CLP products will make their debut.
- Graded polymer will allow us to sponsor serious, reproducible, scientific, agricultural research studies. Over the last few years there was some success in securing federal and state funds for projects. Researchers are encouraged to contact us by e-mail with an outline of projects which lack monies and/or sponsorship.
