Cosmetic and personal care products that are intended for storage at room temperature have two options for stability testing realtime and accelerated testing. These are called accelerated tests that put the product under extreme conditions and are supposed to indicate how long the product would last under real life conditions.

Accelerated stability testing cosmetic products. Accelerated Stability Tests Accelerated tests developed because of the relatively short development cycle for cosmetic products enable the prediction of stability. A commonly accepted practice is to support the forecasts obtained from accelerated stability testing by carrying out. Accelerated tests are the most common form of stability testing and are designed to predict the stability of a formula since cosmetics have a short development cycle.
Predictions obtained from these studies are accepted provided that the producer carries out regular post-launch studies of samples stored at ambient temperatures. Accelerated Stability TestsAccelerated tests developed because of the relatively short development cycle for cosmetic products enable the prediction of stability. A commonly accepted practice is to support the forecasts obtained from accelerated stability testing by carrying out periodic post-launch monitoring of retained samples stored at ambient temperatures.
Stability Testing of Cosmetics. The purpose of stability testing cosmetic products is to ensure that a new or modified product meets the intended physical chemical and microbiological quality standards as well as functionality and aesthetics when stored under appropriate conditions. Because the development cycle of cosmetic products is relatively.
Intertek personal care and cosmetic product stability testing helps ensure the products functionality and aesthetics are not adversely impacted during its intended shelf life and consumer use. Testing can be undertaken under controlled accelerated or real-time conditions. Appropriate testing helps ensure.
Cosmetic stability studies normally include different accelerated storage conditions where the samples are kept in elevated temperature 37C 40C or 45C during a period of 1 to 3 months depending on the type of the product and the needs of the market. 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. Due to the different nature of each cosmetic product no mandatory Stability Test was established.
Real-time stability tests are usually performed at room temperature and take as long as the claimed shelf life on cosmetic product labels. Due to time constraints most companies decide to perform the accelerated stability test which normally includes keeping the samples at elevated temperatures 37 40 or 45 degrees Celsius over a period of three months. Cosmetic and personal care products that are intended for storage at room temperature have two options for stability testing realtime and accelerated testing.
Many people are unaware that stability testing can be performed at an accelerated rate. Accelerated shelf life testing is based on the idea that a product that is exposed to extreme. These are called accelerated tests that put the product under extreme conditions and are supposed to indicate how long the product would last under real life conditions.
So if we want to give a shelf life to a product and we also want to get that product to market in 6 months then we will need to check that nothing will change to it over time. Stability test is required for all cosmetic products without any exceptions. We should also point out that if anything changes in the product formula packaging or manufacturing process the stability and compatibility test needs to be done again to re-evaluate the product stability and its.
This review of the available guidelines that assess the stability of cosmetic products can serve as a technicalscientific framework to identify the most suitable methods for the assessment of the stability of cosmetic products. This document does not aim to specify the conditions parameters or criteria of stability testing. Synopsis The principles on which stability tests are based are reviewed.
The need to differentiate between product stability and product-container compatibility is emphasized. Recognition of this distinction is fundamental to the efficient organisation and execution of stability tests. There are no set rules on how you must conduct a stability test for cosmetic products.
Of course for cosmetic OTC products like sunscreens APDO or dandruff shampoos the FDA has specific stability test requirements that you have to follow. See the FDA website for more information. Here is a basic format you can follow for conducting a cosmetic formula stability test.
Because of the very wide variety of cosmetics there is no standard overall protocol and the study design is determined after consideration of the normal foreseeable conditions of storage and use of the product. In most cases accelerated stability studies are performed specific temperature hygrometry light and duration conditions over at least 5 months. PH value viscosity density or others.
Accelerated Stability Test also known as normal or exploratory stability test. This test is a predictive study that can be used to estimate the expiry date of the product.
