What is Tinosan SDC?
Tinosan SDC is a relatively new to the market all natural preservative and antimicrobial based on a stabilized silver complex produced by a unique electrochemical process with silver and citric acid. It is water-soluble silver citrate.
It is formaldehyde free, non-halogenated, contains no phenols and no quaternary ammonium compounds.
It passed challenges tests for Gram-negative and Gram-positive bacteria, Yeast and Molds and fulfilled USP test requirements in formulations with anionic and nonionic emulsifiers and shampoos.
Tinosan SDC provides broad-spectrum antimicrobial activity and is effective against unwanted skin bacteria and pathogenic microorganisms. Its fast-killing activity makes Tinosan SDC an effective antimicrobial for home and personal care products and hospital formulations.
Bacteria have been exposed to silver ions for over 4 billion years and no widespread resistance has been evident to date. The risk for microbial resistance to Tinosan SDC is considered low.
Tinosan SDC has meet FDA standards for these intended uses.
Applications include: Deodorant active for Personal Care Products
Antimicrobial active ingredient for Personal Care Products
Preservative for Personal Care Products
Biocide for Household and hospital products
Tinosan SDC is a colorless, odorless, low viscous liquid. It has no known adverse effects on human health and is classified as not hazardous under OSHA regulations. Its LD50 is >5000 ml/kg. (Note: The LD50 of water is around 190 ml/kg)
In testing Tinosan SDC caused no skin or eye irritation and is not a skin sensitizer.
Usage and incorporation:
PH = 1.4 to 1.6
Skin care products 0.1% - 0.3%
Home Care Products 0.1% - 0.5%
Good compatibility has been shown in most formulations at a pH <7 with anionic and non-ionic surfactants, emulsifiers and the amphoteric surfactants. Tinosan SDC is compatible with many other antimicrobial actives and most other preservatives.
Tinosan SDC is highly water soluble and easy to incorporate into the aqueous phase of gels, surfactants and emulsions made by cold process. In the manufacturing of emulsions produced by hot process, Tinosan SDC should preferably be added to the final formulation after the emulsion has cooled down to below 122 degrees. For formulas sensitive to acids Tinosan SDC can be pre-neutralized prior to addition to the product.
Exposure of Tinosan SDC to pH’s higher than 7 and temps above 122 degrees should be avoided in order to achieve optimal formulation stability and prevent precipitation and discoloration.
We also recommended Tinosan SDC it be used in conjunction with Potassium Sorbate @ 0.3% for additional protection against mold, fungus and yeast spores.
High salt concentrations can reduce the bactericidal activity, whereas anionic surfactants in a concentration of 0.03% to 1 % increase the biocidal efficacy of Tinosan SDC.
Additionally, Tinosan SDC exhibits strong activity against Corynebacteria and significantly reduces body malodor in deodorant preparations making it an excellent deodorant active.
Storage & Shelf Life:
Tinosan SDC is considered inert until combined with a formulation giving it an indefinite shelf life. It is light sensitive and should be stored in a container that protects it from light. Final formulations sold in transparent packaging and exposed to bright light may exhibit reduced antibacterial effectiveness. Products preserved with Tinosan SDC should ideally be stored under cool, dry conditions and used within 1 year of manufacturing.
Availability: It has not been widely advertised because the manufacturer believes, as we do, that the product sells itself. Many small businesses are now using it as their primary preservative system.

Should not be used by individuals with Silver allergies.
Additional Technical and Scientific Information
Colloidal Silver particles are solid silver particles suspended
in a liquid with a negative charge. Colloidal silver is a suspension of
submicroscopic metallic
silver particles in a colloidal base.
Tinosan SDC is NOT colloidal Silver. It is the silver citrate and only contains Silver Ions which are positively charged.
Silver Ions when in contact with the human body (because of there positive charge), quickly combine with chloride to form an insoluble compound called silver chloride which is is basically non-reactive in the body. If ingested the hydrochloric acid in the digestive tract supplies the chloride ions that will cause ionic silver to quickly form silver chloride, an insoluble compound that will not dissolve or deposit itself in the bodies tissues and is quickly excreted by the kidneys in the urine. If ionic silver were to be absorbed into the blood stream or interstitial spaces via the skin it would encounter a large supply of chloride ions and again quickly form silver chloride and be excreted via the kidneys.
Argyria
Argyria
is a blue skin discoloration resulting from excessive exposure to
silver. Silver metal workers, people who mine silver, and people who
take colloidal silver supplements can all develop this rare condition. Once argyria
develops, it is very challenging to treat. Continued exposure to silver
either through skin contact, ingestion or inhalation can result in
severe complications.
There are two types of argyria: localized and universal.
Topical treatments such as nasal sprays contain silver compounds that can cause localized argyria at the mucus membranes. Some tattoo colors also have a silver base, which can cause localized argyria.
Medications now seldom include silver compounds, and reputable tattoo
parlors do not employ silver in any of their dyes. Tooth fillings made
from silver do contribute to a slight risk for developing the
condition, so as a result, fillings do not usually contain silver today.
Universal argyria
occurs when the people ingest silver particles in medicines, or through
exposure to fine silver dust. In these cases, the blue color of the
skin is more diffuse, but may at first be noted mostly on areas of the
skin that receive sun exposure. The face, hands, and chest may all turn
a bluish-gray. In the worst cases, all of the skin will turn blue, and
organs like the spleen and liver may also have a bluish cast.
Unlike Colloidal Silver, Tinosan SDC does not cause or contribute toArgyria.

Pure Bioscience Sets A Silver Standard for Germ-Killing Products
Pure Bioscience founder
and CEO Michael Krall smiled knowingly when he met me recently at the
company’s El Cajon, CA, headquarters. “You chose a great time to write
this story,” he told me. “We are now starting to enjoy the fruits of
our labor. There’s gold in silver, oh yes.”
Silver is the key ingredient at the heart of Pure Bioscience (NASDAQ:PURE),
a company with just 25 employees that has developed a patented
formulation known as SDC—silver dihydrogen citrate—as a new type of
disinfectant. The company describes SDC as “an electrolytically
generated source of ionic silver” that serves as the basis for a broad
range of germ-killing products. Pure Bioscience also says SDC is the
first new antimicrobial disinfectant the U.S. Environmental Protection
Agency has registered in more than 30 years.
Pure Bioscience says SDC is a fast-acting, non-toxic, “green”
alternative to chlorine, formaldehyde and other commercial
disinfectants that have drawn some environmentalists’ ire. It can be
used as the active ingredient in home and personal care products,
cosmetics, deodorants, cleanwipes, drinking-water systems, acne
products, wound care products, and even agricultural products because
it kills a broad spectrum of bacteria, viruses and fungi. Krall says
highly publicized outbreaks of bird flu and other health threats,
including MRSA, Staph, and SARS, have helped to drive public interest
in the company’s flagship product.
Three months ago, Pure announced a deal with Swiss chemical giant Ciba,
which markets Pure’s SDC in their personal products catalog under the
tradename “Ciba Tinosan SDC.” Krall now says there will be hundreds of
products. “This is going to be really exciting,” he says. “In five
years we will be a very big company, unless someone acquires us.”
The 56-year-old CEO says he founded the company as Innovative
Medical Services in 1992 to provide services and products for the
pharmacy market, including the Fillmaster, an easy-to-use tool for
pharmacists who mix antibiotics. The company sold approximately 20,000
Fillmasters, but Krall says, “We couldn’t create more business around
it, so we started looking for other technologies.” The company began
to concentrate on the antimicrobial field in 1999, and changed its name
to Pure Bioscience in 2003. It now has five U.S. patents.
Before starting the company, Krall was the president and CEO of a
San Diego area residential and commercial property development company.
He also worked as a general manager in the hospitality industry. He
says Pure Biosciences was funded in the early years by individual
investors through a few small rounds, which were required only on
special occasions. The company went public in 1996, raising about $4
million in its IPO.
In the fiscal year that ended July 31, Pure Bioscience lost about
$6.5 million on almost $1.5 million in annual revenue. “Creating
anti-microbials is expensive and it takes time,” Krall says. “A new
product has to be perfect. We have been almost a pre-revenue company,
but this is turning now.”
The business model for Pure Biosciences has developed three sources
of revenue: licensing SDC to pharmaceutical companies for development
of new therapeutic products, such as a treatment for athlete’s foot;
partnerships with companies like Ciba to market Pure’s SDC to others
and to sell products under its own labels; and sales of its own brand
of cleaners and other SDC-based products.
“But we can’t do it all,” Krall says. “That’s why we’ve spent years
looking for partners, because we want to stay small and efficient.”
Before I left, Krall asked me if I remembered the Greek patriarch from “My Big Fat Greek Wedding,”
Hollywood’s 2002 surprise hit. In the movie, the father
comically sprays everyone with Windex cleaner. Krall says he should
have used SDC instead.
To demonstrate, Krall sprayed some SDC-based cleaner into his own
mouth, explaining the silver-based germ killer is not toxic—unlike
chlorine-based cleaners. “I do this all the time,” he told me. Krall
says he even used the SDC cleaner to regularly spray the wounds in his
gums after he had root canal surgery.
Our Tinosan SDC comes directly from Ciba.
