Why is Patch Testing Important for Cosmetic Products?
Legal background
Under Regulation (EC) No 1223/2009, cosmetic products must undergo a safety assessment considering relevant toxicological endpoints, including skin irritation and skin sensitisation. Patch Testing and HRIPT can provide additional human tolerance data and support claims such as Dermatologist Tested, Suitable for Sensitive Skin, Non-Irritating and Non-Sensitising, where justified by appropriate evidence.
Benefits of Cosmetic Patch Testing & HRIPT
How skin tolerance testing supports cosmetic safety, sensitive skin and regulatory compliance.
Supports skin tolerance claims
Provides evidence for claims such as Dermatologist Tested and Suitable for Sensitive Skin.
Evaluates irritation potential
Hels assess how well the cosmetic product is tolerated under controlled conditions.
Strengthens claims substantation
Provides human study data to support cosmetic marketing and performance claims.
Supports product safety evidence
Adds valuable skin compatibility data to the overall cosmetic safety assessment.

FAQ
Frequently Asked Questions
A cosmetic patch test is a controlled human skin study used to evaluate the local skin tolerance of a cosmetic product. The product is applied to intact skin, typically under a patch for a defined period, and the application site is assessed for signs of irritation.
A Human Repeat Insult Patch Test (HRIPT) is a repeated-exposure skin study used to evaluate whether a cosmetic product may cause irritation or sensitisation under controlled test conditions. It is commonly used as supporting evidence for cosmetic skin tolerance and related marketing claims.
Patch Testing is not automatically mandatory for every cosmetic product placed on the EU market. However, under Regulation (EC) No 1223/2009, the cosmetic safety assessment must consider relevant toxicological endpoints such as skin irritation and sensitisation. Human volunteer studies may provide useful supporting evidence depending on the product and its intended claims.
Obelis helps identify the appropriate Patch Test or HRIPT study design, coordinates testing through specialised laboratory partners and supports the use of results for skin tolerance claims, cosmetic claim substantiation and regulatory compliance.
