title: Estimating dilutions for patch testing skin care products: a practical method.
abstract: When patch testing, it is helpful to patch test with the patient's own topical products. However, the thickness (viscosity) of the product often prevents easy measurement for dilution. A method of estimating volume: volume dilutions that requires minimal investment in supplies is presented. This method is only applicable to personal products and is not suitable for industrial or household chemicals.
