Quality Control PLUS
To help insure product integrity, HYDRON Technologies goes beyond industry standards by performing a series of quality assurance tests on each approved formulation, as well as each and every production batch…all in an effort to protect your brand name. For an article on how quality control can effect your business, click here "You Don't Know, What You Don't Know".
-
ACCELERATED SHELF LIFE to indicate the reaction of a formulation over an extended period of time, typically indicating results of two and three year shelf life. Samples are evaluated for precipitation, pH, viscosity, specific gravity, color and aroma
-
ELEVATED TEMPERATURE STABILITY determines the stability of a formulation when exposed to elevated temperatures of up to 115°F for a minimum period of 72 hours. An important issue when a shipment or storage facility may be exposed to extreme summer temperatures.
- FREEZE/THAW STABILITY determines the low temperature stability through a minimum of three freeze/thaw cycles at temperatures of -23°C to - 26°C (-10°F to -15°F). Another key concern when a shipment or storage facility may be exposed to freezing winter temperatures.
- MICROBIAL CHALLENGE TEST Preservatives are one of the key irritants in topical formulations, but necessary to protect the integrity of a product. Since many factors can compromise the effectiveness of a preservative system, this critical test challenges the effectiveness of a formulation's preservative system, utilizing the U.S. Pharmacopoeia Anti-Microbial Preservative Effectiveness Study protocol.
- COLOR STABILITY The color of a product can change with time or when subjected to various light sources, such as UV or fluorescent light. Utilizing a spectrometer, an analytic value is assigned to the color of a product, then the sample is submitted to a variety of light sources via a specifically designed light box. At the end of the test cycle, the spectrometer re-reads the sample and evaluates the color stability.
-
AROMA STABILITY While different key ingredients can react with fragrance over time, this test determines if the fragrance of the formulation is maintained throughout the expected life of the product.
- PRODUCT SPECIFICATIONS outlines the acceptable ranges for pH, viscosity, color, aroma, consistency, etc. for evaluating each production batch by to insure consistency time after time.
