Physical Stability Testing

The excitement and anticipation of preparing your new product range for market can quickly turn sour if what's inside the packaging isn't stable. Unstable products can lead to a whole variety of problems including bacterial contamination, packaging failure due to clogging or leaking, an unpleasant look and/or feel and most importantly a loss of efficacy.

While there is no government standard for stability testing or shelf-life there are some sensible precautions that you should take to protect both your customers and your professional reputation. With that in mind it is hard to see why anyone would choose not to find out how their product stands up over its expected shelf life!

New Directions has partnered with Realize Beauty to offer basic physical stability testing on-site for your convenience. We can now offer a 12 or 24 week program that will give you an insight into how your product will perform on-shelf for between 12-24 months. In addition, we can organize microbial testing which help show how your products stand up to repeat use.

We are dedicated to helping your business and brand succeed and as such would welcome the chance to help you avoid the costs, headaches and financial implications of product failure.

Our stability protocol starts from 12 weeks or 24 weeks accelerated stability testing giving you an idea of how your product might stand up over a 2 year shelf life period.*

So why not talk to our technical team today and find out why a safe cosmetic is about so much more than just which chemicals you leave out ...

*Accelerated testing is carried out at 40°C and gives an idea of how your product ages over time. A general rule of thumb is that one week testing at 40°C is equivalent to one month at room temperature although this can vary from product to product. In any case accelerated testing should only be seen as a stop-gap for real-time stability to cover the time when the product is first released for sale.
