Materials and methods

Test guideline

Qualifier:

no guideline followed

Principles of method if other than guideline:

To determine by epidermal contact the primary irritation potential of the test material, ColaMoist.
53 subjects, male and female age range 16 - 77 years were selected for this evaluation. 52 out of the 53 completed the study. The remaining person discontinued for personal reasons unrelated to the study.
Participants had to be over 16 and have no visible skin disease or skin complaint which might be confused with a reaction.
They were prohibited to use topical or systemic steroids and/or antihistamines for at least 7 days prior to the study initiation.
Completion of a medical history form and a consent form were required.
Exclusion criteria included; ill health, taking medication, pregnancy or nursing, a history of adverse reactions with cosmetics or personal care products.
