Determination of the Sun Protection Factor (SPF) of a Cosmetic Daily De-fence Skin Cream
January 15, 2019 updated by: GlaxoSmithKline
Determination of the Sun Protection Factor of a Cosmetic Daily Defence Skin Cream
The purpose of this study is to determine the SPF of the test product according to the International Standards Organization (ISO) 24444:2010 methodology (In vivo determination of the SPF).

Detailed Description
A single-center, randomized, evaluator blind, intra-individual comparison, no treatment and positive controlled clinical study to determine the SPF of Physiogel Daily Defence Protective Day Cream Light as per ISO 24444:2010.
The provisional minimal erythemal dose of unprotected skin (MEDu) for each subject will be determined before starting the test phase.
Once the provisional MEDu for a subject has been determined, the three test sites will be demarcated.
The test product and positive control (P3 reference sunscreen formulation) will be applied to two of the three test sites.
The other test site will remain unprotected.
All three test sites will be exposed to UV radiation at the expected MED and subsequently evaluated for erythema 16-24 hours after UV exposure.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Test product
This arm will include all the test sites on the participants back where test product (Physiogel Daily Defence Protective Day Cream Light) will be applied.
|
Investigator controlled, topical application to the epidermis at a dose of 2 milligrams per square centimeter (mg/cm2).
Single application.
|
ACTIVE_COMPARATOR: Reference product
This arm will include all the test sites on the participants back where reference product (ISO 24444:2010 P3 standard sunscreen) will be applied.
|
Investigator controlled, topical application to the epidermis at a dose of 2 mg/cm2.
Single application.
|
NO_INTERVENTION: Negative control
This arm will include all the test sites on the participants back which will be left unprotected.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Arithmetic Mean of Individual Sun Protection Factor (SPFi) Value
Time Frame: Up to 24 hours post UV exposure
|
Arithmetical mean of all valid SPFi values of each product on each participant was calculated from the individual Minimal Erythemal Dose (MED) on product treated (MEDp) test sites in relation to unprotected (MEDu) test sites 16-24 hours after exposure to ultraviolet (UV) radiation (SPFi = MEDp/MEDu).
The Minimal Erythemal Dose (MED) was defined as the lowest dose of UV radiation that produced the first perceptible unambiguous erythema with defined borders appearing over most of the field of UV exposure, 16 to 24 hours after UV exposure.
No inferential statistical analysis has been performed for this outcome.
Test and reference products achieved a 95% CI of ±16.4% and ±16.6% of the mean SPF.
These data meet the statistical criterion defined in ISO 24444:2010 as the 95% CI is within ±17% of the mean SPF.
