From Dr Ben Oldag explaining the fundamentals of how the Wood Preservative works
Wood contains two different forms of moisture referred to as "FREE WATER and BOUND WATER. Free water harbors in the fiber structure of the wood. Bound water is found in the Hydroxyl molecule that is the sole make up of cellular compounds.
Southwestern Cedar Oils Wood Preservative is a solvent treatment. Solvents displace free water from the fiber structure of wood. The silanes we use in the formulation are water scavengers. Since they are of extremely low molecular weight they are capable of penetrating the cell wall structure of the molecule and attacking the water inside the molecule. The water is replaced with a SI-Jel Matrix, a pliable compound made up of silicone and cedar oil. This phenomenon is created by a catalytic conversion that uses the bound water to trigger a hydrophobic reaction. The un-utilized excess water is then released and exits the wood in the form of ethanol gas. The Cedar Oil component of the formulation performs as a synergist which allows the solution to bond with the water and subsequently acts as a termiticide and fungicide that provides additional protection to the wood.
Summary: When the hydroxyl group molecule is stabilized, the wood is moisture free. The molecules hydrogen and oxygen tails are sealed from liquid or air borne moisture and cannot expand or contract as they would in non-stabilized wood. Subsequently, the absence of moisture is the absence of issues and the early stages of wood Petrification are triggered. Petrified wood is moisture free wood laced with silicone deposits.

This dynamic product is the advancement of a Prior Art, solvent based wood treatment, used in the early years of the Twentieth Century and discontinued with the onset of the USA- FIFRA registration issues of the Mid Fifties. Cedar Industries, in concert with GT Products Company, a specialty Silicone manufacturer in Texas, and with the use of a hydrocarbon carrier developed by Conoco Phillips Petroleum Company, has invented and produced a next generation solvent based wood preservative utilizing politically correct Green components, the basis of this dynamic product. The process theory of SWCO Wood Preservative is simple. The introduction of a highly penetrating natural solvent cross-linked with Cedar Oil and Silicone to the wood cellular structure succeeds in the closing and drying of the Hydrogen tails of the Hydroxyl Molecular group found in wood media. The closure of the molecule chain eliminates the opportunity of the media to harbor moisture content either in airborne (humidity) or liquid form. This results in dimensional stability, water resistance and pest control. Penetration with the proprietary hydrocarbon solvent displaces existing moisture content in the wood which results in Kiln-less Drying, an instant evacuation and exodus of H2o compounds from the media. Unlike aqueous treatments that are subject to entry and exit by moisture and the continuous leaching of toxins, water can never displace a solvent carrier from its impregnation to wood cellular. After entry to the wood through the vascular feeding system, (summer sap ring) and migration to the adjoining sap wood, (winter sapwood ring) the annular growth rings are sealed using the trees own resins as a catalyst that forms a waxy like substance in the media cellular structure. This enhancement mirrors that of internal gluing or the addition of steel plates to the wood, strengthening the composition and limiting the flexibility of the wood. SWCO Wood Preservative can be used as a wood preservative on closed cell woods including but not limited to Black Spruce. SWCO Wood Preservative is effective in treating all types of Hardwoods and Softwoods.

How This Product Works:
Petriwood solution penetrates the cellular structure of green or kiln dried timber and wood media derivatives such as OSB and particle board. SWCO Wood Preservative proprietary non VOC solvents cross linked to specially refined red cedar wood oil turpenes and siloxene synergist, displace moisture while entering all wood structure through their vascular system.
SWCO Wood Preservative carriers deliver the antimicrobial and termiticidal agents to the wood cell structure where it is encapsulated and solidified by permeable silicone molecules. Natural wood oils are transformed to a wax-like consistency similar to glue which mirrors the effect of an internal adhesive increasing the solidity of the treated product. SWCO Wood Preservative treated wood fibers resist efforts of all cellulose consuming insects and moisture borne fungal and decay organisms. SWCO Wood Preservative treatments result in water resistant and dimensionally controlled building material for above ground and subterranean construction. Paint or stain ready in 72 hours. There is no offensive odor or transferable residue associated with SWCO Wood Preservative. All components are FDA, GRAS and EPA 25b list approved as minimum risk pesticides authorized by the Food Quality Protection Act of 1996.
How To Use This Product on Dry and Green Wood:
Brush – Apply liberally from both sides and ends. Keep the surface soaked or wet until absorption reaches the level of penetration desired.
Roller – Apply with heavy knap roller keeping all surface area wet until absorption reaches the degree of penetration desired.
Spray or Airless – Apply repeatedly with heavy coats to point of run off. Stacked lumber should be separated with slats between layers. Spray ends and all surfaces until absorption reaches the degree of penetration desired.
Submersion – The most desired method to treat green and wet material for drying or preserving structural lumber, plywood sheet products, oriented strand board, particle board, rail road ties, fencing material and wood flooring products. The use of masonry mud boxes, stock tanks and open barrels where total submersion from one or both ends is desirable. Treated material can be reversed for full coverage. Horizontal treatments require weight to offset buoyancy issues. Submersion times from 15 minutes to 1 hour are recommended as seen on the chart below. Excess submersion may or may not enhance performance however, is never detrimental to the objective. Does not compromise pre-treated surfaces such as hardwood floor or laminates.
Pressure Treatment – Standard pressure over vacuum or isolated pressure treatment protocol can be used with SWCO Wood Preservative wood preservatives. Minimal exposure is required as there is no cellular rejection of foreign objects as with aqueous penetrates. Resistance is minimum to the highly acute cedar oil turpene extracts and silicone compound. Elapsed vessel time is suggested at 15 minutes. Normal pressure treatment protocol should be calculated subject to equipment manufacturers’ instructions.
Evacuation – Drip dry time of 3 to 5 minutes is recommended for salvage of unused SWCO Wood Preservative solution. Stack time of 1 hour is suggested, however not required as SWCO Wood Preservative cures are triggered by catalytic reactions from oxygen.
Desired Penetration – Total dimensional control is obtained with complete penetration. Insect, fungal and decay control can be achieved with partial penetration. Construction window treatments of minimum penetration will provide water and surface mold resistance for up to 90 days. Southwestern Cedar Oil Industries suggests a minimum of 10 minutes for satisfactory results of all treatment objectives.

"Pressure treated" lumber is the euphemistic term for wood treated with extremely dangerous chemicals that are toxic to humans and the environment. Chromated copper arsenate (CCA) gives "treated" lumber a green color. Ninety percent of outdoor wooden structures are made with "pressure treated" wood. It is used for decks, fences, raised garden beds, children's play equipment, picnic tables, and pet houses. (1) Would consumers have been so eager to purchase "pressure treated" wood for home projects if it were accurately labeled "arsenic treated" wood?
Pentachlorophenol (penta) and creosote are toxic chemicals used in treating wood for commercial use such as telephone poles and railroad ties. Creosote gives wood a dark brown look and has a distinctive odor, particularly noticeable in warm weather. The largest users of treated wood poles are the utility and telephone companies. (2)
The sole purpose of these chemicals is to kill living organisms such as insects or fungus. The toxicants easily migrate into soil, water, and the air we breathe, posing serious health risks to human life and the environment. (3)
"Pressure treated" wood contains some of the most potent cancer agents, promoters of birth defects and reproductive problems. The chemicals are nervous system toxicants, endocrine disruptors, and estrogen mimics implicated in breast and prostate cancers.
The inorganic arsenicals are recognized for their oncogenicity (causing cancerous tumors), mutagenicity (causing genetic damage), fetotoxicity (killing the developing fetus), birth defects, and other reproductive effects. (3)
Pentachlorophenol and its contaminants--dioxins, furans, and hexachlorobenzene--are recognized for their oncogenicity, fetotoxicity, and teratogenicity (causing birth defects). Creosote, used primarily to treat railroad ties, is known for its oncogenicity and mutagenicity. (2,3) Recycled railroad ties are often used in home landscaping projects by unsuspecting homeowners.
Workers who paint penta on poles in the field face a 340% increased lifetime risk of cancer, according to data compiled by the US Environmental Protection Agency (EPA). It is estimated that exposed workers will develop three cancers in their lifetime. This is a serious problem that exposes thousands of workers on a daily basis to dangerous wood preservative chemicals, upon which the EPA has been very slow to act. (2)
Open backyard burning of "treated" wood poses additional health risks to residents exposed to pollutants that become airborne with smoke and in the remaining ash. Some states are considering legislation that would ban open burning.
There are approximately 795 wood preservative treatment plants in the US, many of which are listed as superfund sites by the EPA, and pose serious health risks to humans and the environment in the communities where the chemicals are manufactured or used. The EPA has slated these sites for highest priority for clean-up. (2)
Children pick up arsenic on their clothes, hands, and bare feet from playing on treated wood equipment, from walking on treated decks, or playing in dirt with leachates from treated wood products or utility poles. (1)
Children exposed to soil contaminated with penta leaching from utility poles have a lifetime cancer risk as high as 2.2 in 10,000. Contact with treated wood itself poses a risk of 6.4 in one million. EPA's one-in-a-million threshold is greatly exceeded by 220 and 6.4 respectively. Children are further exposed to penta in drinking water, food, and from residential uses. (2)
Not even the unborn child is safe from exposure to these toxic substances. Early findings of teratogenic (birth defects) and fetotoxic (toxic to fetuses) properties of penta were reaffirmed by the EPA. (2)
Contrary to industry and EPA "assurances of complete safety" of older structures made with "treated wood," advocacy groups such as the Environmental Working Group (EWG), Healthy Building Network, and the Environmental Quality Institute (Univ. of NC) found wood up to 15 years old to still be grossly contaminated. (1) Test kits were distributed to people to learn if arsenic wiped off CCA treated wood structures, and if soil underneath structures might still be contaminated. The amount of arsenic wiped off was considered equivalent to the amount of arsenic a small child might get on their hands from contact with the wood. The amount was found to exceed what the EPA considers "acceptable" in drinking water. Forty percent of soil samples taken from backyards and parks contained enough arsenic to qualify as EPA superfund sites. (1) Nearly all wood playground equipment has been treated with toxic chemicals. New precautions recommend that children wash their hands thoroughly with soap and water after coming in contact with any treated wood equipment. The Consumer Product Safety Commission (CPSC) claims that "children could face an increased lifetime risk of developing lung or bladder cancer from using playground equipment treated with chromated copper arsenate." Jane Houlihan, a vice president with the Environmental Working Group, believes, "The CPSC has substantially underestimated the cancer risk." (4)
Millions of American children are exposed on a daily basis to these carcinogenic chemicals in the supposed safety of their own backyards, school and public playgrounds. It defies logic to accept modern medicine's claims that causes for childhood cancer remain unknown, and yet, does nothing to pursue possible avenues of exposure, or test lipid tissue for accumulated toxins. As long as the experts refuse to ask the right questions, the public won't be given the right answers.
