ASTM E1490-92(1997)

1.1 The objective of this practice is to provide procedures that may be used in the design and analysis of studies of skin care products that compare qualitatively and quantitatively various sensory attributes and their intensity (or strength) over time. These properties can then be used to define the performance of skin care products to provide direction in product formulation, research guidance, and claim substantiation.

1.2 Guidelines are provided for the definition of each product attribute or term, range of the rating scales, procedures for the manipulation of product alone and on the skin, selection and training of panelists, handling of products, and skin conditioning prior to tests.

1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
