*Requires five (5) finished product samples to be submitted per product per study. The food industry has a great need to have a shelf-life test in the minimum time possible because of the fierce competition, sudden shortage of agricultural inputs, opportunity loss and low unit value of the commodity. The purpose of stability testing is to ensure that the cosmetic product maintains its intended physical, chemical and microbiological quality, as well as functionality and aesthetics when stored under appropriate conditions. A projected expiry date of fourteen (14) days should have a final time point at 18 to 21 days. Generally limits of acceptance are defined for the evaluated parameters. Must remain stable for at least 15 days when exposed to sunlight. Where relevant, consider stresses, including temperature, that will enable assessment of product integrity under anticipated product exposure conditions. A general standard for accelerated testing… Total Molds and Yeast (Aerobic Plate Count) FDA Bacteriological Analytical Manual (BAM), 8th Edition, Chapter 18, 1998. *Contact Laboratory for Chain of Custody to be submitted with samples. challenge test, if applicable; When applicable, the period after opening (PAO) and its justification. Also the shelf life should be establish beyond the actual expiry date of the product to insure that an out of date product is safe beyond the expiry date marked. *Initial Time Point. After being tested, the sample is returned to the Chemistry laboratory and the pH is measured. Shelf life testing is performed to test the bacterial integrity of a finished product. relative humidity. Accelerated Stability Test – also known as normal or exploratory stability test. Stability testing is an experiment in which samples of the formula are put at different environmental/ storage conditions for a set period of time to simulate what will happen to the product during its life … Values above 60°C are not recommended. Mold /Yeast – Can be spoilage organisms and can produce aflatoxins. Evidence that the composition of the product used for stability testing corresponds to the product actually placed on the market; The results of the preservative efficacy study, e.g. The following tests will be performed according to the AOAC methods cited below. A description of the methodology used to determine the product’s minimum durability. A projected Shelf Life should include a reasonable time for production, Distribution, Sale and Consumption. Contract Laboratory, U.S. Coast Guard for Alaskan Vessel Discharge Program. The laboratory will assist you in setting up a shelf life study. The common and conservative means of the accelerated aging calculation is based on the Arrhenius equation which states that a 10°C increase in temperature doubles the rate of chemical reaction. Accelerated Aging Factor is automatically calculated and provided here for reference 5. Ambient temperature studies are carried out at 25 degrees Centigrade and are conducted in real time. aureus – Staphylococcus aureus is a common cause of food poisoning derived from product handling. Extra Timepoints: $95 per timepoint. Cost Shelf Life Testing: $550.00 – Please send payment with samples It is recommended that accelerated shelf-life studies be accompanied by a shelf-life study conducted under normal storage conditions in order to determine the actual Q10 value.
