Dermatest® guarantee seal of approval

Q: What is the difference between the various seals?

The Original Dermatest ® seals represent traceability of test methods as well as for consumer safety and manufacturer endorsement. Depending on the test design and type of study, the seals have four different categories signifying their importance.

Q: What testing is required to earn the Dermatest® guarantee seal?

The Dermatest ® guarantee seal requires a patch test (brief and localised contact with human skin) on at least 30 test subjects, with no adverse reactions.

The patch test provides information about primary skin irritation and/or existing sensitisations that the product might provoke. Test substances are applied occlusively to the skin at appropriate concentrations. Epicutaneous contact with the test product is therefore restricted in terms of site and exposure time and is intensified by the occlusion conditions, so that absorption of the test substances is promoted. The skin is examined after 24, 48 and 72 hours. If your product passes this patch test, you will receive our “Dermatest® Guarantee” seal of approval in addition to the assessment report and certificate. The seal includes the date when the product was successfully tested.

FAQ

What is the difference between the various seals?

The Original Dermatest^® seals represent traceability of test methods as well as for consumer safety and manufacturer endorsement. Depending on the test design and type of study, the seals have four different categories signifying their importance.

What testing is required to earn the Dermatest® guarantee seal?

The Dermatest^® guarantee seal requires a patch test (brief and localised contact with human skin) on at least 30 test subjects, with no adverse reactions.

What testing is required to earn the 3-star seal?

The 3-star seal is awarded for short-term exposure tests at the site of application, or alternatively for long-term investigations of skin condition or skin function on areas of skin other than the prospective site of application, or open patch testing on the site of application requiring at least 20 test subjects. The 3-star seal represents a significantly more complex study design and carries more weight than a simple patch test.

What testing is required to earn the 5-star seal?

The 5-star seal applies to long-term use tests carried out on at least 20 test subjects over a period of at least 4 weeks on the intended site of application. They provide the maximum possible protection in order to rule out as far as possible subsequent skin reactions among the target demographic: products which have been tested in this way can be termed “clinically tested”.

The 5-star seal applies to the Original Dermatest^® premium sector. Studies with this distinction go beyond determining the potential for skin irritation in terms of their significance. Among other things, application over four weeks can usually rule out sensitisation potential.

How much does the seal cost?

The seals come free of charge provided your product has successfully passed the relevant testing.

How long is the seal valid for?

There is no time limit set for using the seal. However, if anything changes in the composition or formulation of the products, a new test must be arranged. Under EU legislation, the date the testing was carried out must appear on the product packaging, which is why the month and year of testing are included as part of the seal.

Can the colour or design of the seal be changed to suit our graphic design?

This is possible subject to strict limits. Our design manual gives you further information about how our Dermatest seals may be used. Please get in touch.
