| Melanie: Thank you! Now, let’s discuss the purpose of this interview. I would like to discuss the new preservative Tinosan SDC. What is Tinosan SDC? |
| |
Hollie:Tinosan SDC is new to the market all natural preservative and anti microbial based on a stabilized silver complex produced by a unique electrochemical process with silver and citric acid. It is a water-soluble silver salt of citric acid.
INCI: Citric acid and Silver Citrate
It is formaldehyde free, non-halogenated, contains no phenols and no quaternary ammonium compounds. |
| |
| Melanie: Can test results be provided showing the products effectiveness? |
| |
Hollie: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 anti microbial activity and is effective against unwanted skin bacteria and pathogenic microorganisms. Its fast-killing activity makes Tinosan SDC an effective anti microbial 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. |
| |
| Melanie:Is this preservative approved for use in the USA? |
| |
Hollie:Tinosan SDC has been approved for these intended uses.
Applications include:
- Deodorant active for Personal Care Products
- Anti microbial active ingredient for Personal Care Products
- Preservative for Personal Care Products
- Biocide for Household and hospital products
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 50 ml/kg) In testing Tinosan SDC caused no skin or eye irritation and is not a skin sensitizer. |
| |
| Melanie:Does this preservative have an odor? |
| |
| Hollie: Tinosan SDC is a colorless, odorless, low viscous liquid. |
| |
| Melanie:When using this preservative, is it recommended to use in products that have a certain pH range? |
| |
| Hollie: Good compatibility has been shown in most formulations at a pH <7 with anionic and non-ionic surfactants, emulsifiers and the amphoteric surfactants. Also, Tinosan SDC is compatible with many other anti microbial actives and most preservatives. |
| |
| Melanie: What is the recommended usage of this product? |
| |
Hollie:Usage and incorporation:
- PH = 1.4 to 1.6
- Skin care products 0.1% - 0.3%
- Home Care Products 0.1% - 0.5%
|
| |
| Melanie: Is this preservative water soluble? |
| |
Hollie: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 to achieve optimal formulation stability and prevent precipitation and discoloration. 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. |
| |
| Melanie:What is the expected shelf life of this preservative? |
| |
| Hollie: 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. |
| |
| Melanie: Realizing each formulation, depending on the ingredients used, etc. has a different potential shelf life; what is the expected shelf life of a product preserved with this product? |
| |
| Hollie: 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. |
| |
| Melanie: Is this preservative available to the public? |
| |
| Hollie:When Tinosan SDC’s Manufacturer, CIBA, decided to launch this preservative into the market in January 2006 they wanted a company with a primary focus on natural products to be its distributor. Texas Natural Supply was their choice, making it exclusively only available there. It has not been widely advertised because the manufacturer believes, as we do, that the product sells itself. |
| |
| Melanie: Since this preservative contains silver, could it potentially cause Argyria? (Editor's note: from Wikipedia - Argyria is an extremely rare condition caused by the ingestion of elemental silver, silver dust or silver compounds. The most dramatic effect of argyria is that the skin is colored black (blue or bluish-grey)). |
| |
| Hollie:When exposed to the skin it does not turn the skin black. I have applied it full strength to my skin and have even drank a small quantity of it. Being an RN and with years of ER and ICU experience I understand the dangers associated with silver poisoning, which is not possible with this product. It is a silver salt of citric acid and can't cause silver poisoning like colloidal silver. When it is absorbed into the skin it immediately becomes inert because it binds with the free sodium in our bodies and on our skin. It is then excreted out through the kidneys. Remember it is used at 0.1-0.3% so the amount absorbed even if you used a whole bottle of a product would be very tiny and it becomes inert upon contact with sodium. This is why it can be less effective in products with a really high salt content.
Silver is used by the medical profession and has been for years. It is instilled in newborns eyes to prevent gonorrhea and foley catheters are impregnated with it to prevent migration of germs and bacteria up the catheter and into the bladder which is sterile. We also use silver nitrate to cauterize nose bleeds. All of these are examples of silver being used in an effective and safe manner. Ingestion of colloidal silver is and has been controversial for a long time and has lead to heavy metal poisoning. These are not the same silver molecules and behave very differently in the body.

Melanie: Thank you so much Hollie. It has been a pleasure.
Note: It is this author’s opinion, since this interview and after visiting the manufacture’s web site, reviewing the data and MSDS information supplied, I am convinced this preservative is an effective alternative to conventional preservatives. |
| |
| Editors Note: Since Citric acid and Silver Citrate can not be readily made at home, this ingredient would not be considered "100% natural" or "All Natural" according to the NIRC labeling guidelines. However, since the preservative does not include synthetic fragrances, artificial colors or ingredients from petrochemicals, it could comprise a portion of the products formula and meet the designated labeling requirements for 'Natural' or 'Made with Natural Ingredients' as defined by NIRC. |
