CPSR / PET and Stability Testing

CPSR Laboratory Services

Our core laboratory service consist of Cosmetic Product Safety Report (CPSR), Stability Testing and Preservative Efficacy Testing (PET) Testing. Our testing is aimed at the requirements of EU Cosmetic Regulation 1223/2009. To sell your product legally in the EU and conform to EU Cosmetic Regulation 1223/2009, you need a CPSR, and in addition you could also require a Stability and PET Testing (subject to certain criteria).

Some Useful Notes to Help you compile your CPSR

Below we have compiled advice to help you understand the procedure to follow and the testing requirements for your product.

What do I need to do to sell my products legally in the EU?


To sell cosmetics in the EU you require the relevant testing and CPSRBefore selling your Cosmetic Product (cosmetics, toiletries, creams, lotions, make-up, hair products, deodorants, fragrances, sun care products, shaving products, some teeth products) within the EU, it is a requirement your product is assessed and signed off by a person with the relevant qualifications as defined by EU 1223/2009 Cosmetic Law. The documents created is known as as Cosmetic Product Safety Report (CPSR).

You shouldn't be put off by the law. Providing you are making a legal and well thought out product, the assessment process can be carried our quickly and cost effectively by Naturallythinking.

In order to produce a CPSR, our assessor will require the following

  • The formulation, including percentages of each ingredient
  • A Safety Data Sheet (SDS) for each ingredient and sometimes a Certificate of Analysis (COA) (these are available from your ingredient supplier)
  • The type and size of packaging for the product, including closure / dispenser (your product packaging supplier can supply you all the relevant information)
  • Stability Information on the product. If this product has been on the market for a long time, it maybe possible to use historical data, but normally Stability information is established by a Stability Test (see below).
  • Preservative Efficacy Test Data, only relevant if your product contains water. More details can be found below on Preservative Efficacy Testing.

Once your CPSR has been compiled, you are nearly there. You will need to notify your product on the Cosmetic Product Notification Portal (CPNP) which is a free service and can be done online by yourself once you have your Cosmetic Product Safety Report in your hand.

You will need to keep information about each batch of ingredient you purchase and the batches you create. If you have any complaints about your product, you need to keep a record of all complaints. You record this information and keep it safe alongside your Cosmetic Product Safety Report. This is then known as your Product Information File (PIF).

You are now ready to sell your product within the United Kingdom and EU.

What is a Cosmetic Product Safety Report (CPSR)?

Cosmetic Product Safety Report CPSR to sell in the EUA CPSR is a report on the safety and legality of a cosmetic product. This report can only be signed by a person with the relevant qualifications under EU 1223/2009 Cosmetic Law.

All products considered a cosmetic will require a Cosmetic Product Safety Report (CPSR). Products include all cosmetics, toiletries, creams, lotions, make-up, hair products, deodorants, fragrances, sun care products, shaving products, some teeth products.

We do not need to physically see your product in order to create your CPSR.

What is Preservative Efficacy Test (PET), also known as a Microbiological Test?

A preservative efficacy test, tests the effectiveness of a preservative in a cosmeticA Preservative Efficacy Test ensures the effectiveness of the preservation system in your Cosmetic Product. If a product contains water, it will require a Preservative Efficacy Test. Testing involves taking a sample of product and combining with 2 bacteria and 2 fungi. Over a 30 day period the ability of your product to kill and maintain a bacteria period is monitored. If your product passes to ISO standard, we will give you a pass certificate that will enable you to complete a CPSR.

Not all products require a PET test, the following explains the scenarios when you will not require a Preservative Efficacy Test.

  • Your product contains less than 3% water (including floral waters etc.)
  • Your product has a pH of 10 or more or a pH of 2 or less
  • Massage Oils, Facial Oils and other oils preparations that are 100% Oil will not require a PET Test.
  • Powders will not Require a PET Test.
  • 100% Wax Products will not Require a PET Test
  • 100% Butter based products will not require a PET Test (this excludes body butters which are blended with water).
  • Soaps made through Saponification (the old fashioned way) (this excludes glycerin and melt and pour based soaps)

If your product requires a PET Microbiological Test, the CPSR cannot be created until the testing information is completed.

A PET Microbiological Test takes 30 days to complete and an additional 10 days in final screening (40 in total). We publish the schedule of test dates on the PET Microbiological Test ordering page. We advise booking your product testing slot early to avoid missing out on the next testing date as demand is high and the testing capacity fills up very quickly for each date. We advise you to get your PET Testing submitted and completed as soon as possible, so as not to delay your CPSR.

What we Require to Perform Your Preservative Efficacy Test

In order to perform the Preservative Efficacy Test, we require a 100ml sample of your product.

What is a Stability Test?

A preservative efficacy test, tests the effectiveness of a preservative in a cosmeticThe purpose of a stability test is to assess the chemical, microbiological, physical stability of a product. The test assesses whether the quality, functionality and aesthetics when stored under appropriate conditions are maintained to a level that should be expected of the product.

The testing data will determine the expiry date that your products have.. This is the date you will place on your products packaging and it is the date that will be used in your Cosmetic Product Safety Report (CPSR).

We take your 100ml bulk sample and divide it into inert glass jars for testing. These will form the control. We test your control at three different temperatures 4c, 25c and 45c. Separately we test 2 supplied samples of your product in the final packaging, one at 25c and one at 45c.

As part of your stability test, we will evaluate scientifically the shelf life of your product. The stability test data, will be the data that is used in your Cosmetic Product Safety Report (CPSR) as the recommended shelf life and the expiry date / period after opening that goes on your packaging.

Throughout the testing time, we measure the, pH, Viscosity, Appearance, Odour and Product Weight Lost. Continual evaluation of the product allows us to measure these variables and the effect of time, temperature and packaging on your product.

What we Require to Perform Your Stability Test

We require 2 of your products in your final packaging (including lid) and 100ml of your product in any packaging of your choice (we will decant this into our control glass containers).
