Deodorant Testing & Antiperspirant Testing
Clinical testing of deodorant and antiperspirant products to evaluate efficacy, sweat control, odour reduction, and skin compatibility.
What You Can Expect
Deodorant and antiperspirant testing is designed to evaluate the efficacy, performance, and skin compatibility of underarm personal care products.
Studies assess how products perform in controlling sweat, odour, and underarm comfort under controlled or real-world use conditions.
All testing is conducted on cosmetic, toiletry, or personal care products only, and is not intended to support medical or hyperhidrosis treatment claims.
Study Design
Study design varies depending on product type (e.g. roll-on, stick, spray, gel) and intended claims.
Clinical protocols typically involve controlled application over a defined period, with assessments carried out at baseline and at multiple time points throughout the study.
Where appropriate, studies may include both in-clinic assessments and in-use home trial conditions.
Assessment Methods
PCR uses a range of established methods to evaluate deodorant and antiperspirant performance, including:
- Gravimetric sweat rate measurement (where applicable)
- Clinical grading of odour intensity
- Expert assessor evaluation under controlled conditions
- Participant self-assessment questionnaires
- Skin compatibility and irritation assessments
- Standardised product performance tracking over time
These methods allow for both objective measurement and user-perceived effectiveness.
Key Evaluation Areas
Studies typically assess product performance across the following criteria:
- Reduction in sweat production or visible perspiration
- Odour control and long-lasting freshness
- Skin comfort and irritation potential
- Overall user satisfaction and product performance
- Durability of effect over defined time periods (e.g. 24–72 hours depending on claim)
What the Data Supports
Results from deodorant and antiperspirant testing can be used to support claims such as:
- 24–72 hour sweat protection (depending on study design)
- Effective odour control throughout the day
- Reduces underarm wetness
- Gentle on skin / suitable for sensitive skin
- Clinically tested performance claims for marketing and packaging
