ASTM E2082-12

Standard Guide for Descriptive Analysis of Shampoo Performance

SIGNIFICANCE AND USE
6.1 The methods outlined in this guide can be used to qualitatively and quantitatively describe the performance and sensory characteristics of shampoos.  
6.2 The methods described in this guide may be used for product formulation and research guidance as well as for quality control.  
6.3 These methods may be used by individuals who familiarize themselves with these procedures and who have previous experience with sensory evaluation.  
6.4 Variables that may affect results include, but are not limited to, water conditions (for example, hardness), hair type, and hair condition. These variables should be controlled or accounted for in the experimental design.  
6.5 These are suggested procedures and are not intended to exclude alternate methods, which may effectively provide the same or similar results.
SCOPE
1.1 The objective of this guide is to provide procedures which may be used in the design, execution, and analysis of studies to quantitatively assess the objective sensory attributes of shampoos. This is one of many appropriate techniques used in the hair-care industry. These attributes can then be used to define performance of shampoos and to provide direction in product formulation, research guidance testing, and claim substantiation. This guide includes the sensory properties involved in dispensing a product, as well as the attributes pertinent to shampooing swatches, half and whole heads. Although this guide is specific to shampoos, the procedures should be applicable to most hair-care products.  
1.2 Guidelines are provided for the definition of terminology, procedures for manipulation of products, identification/selection of hair type, and assessor training. References for rating scales are not provided in this guide. The user should be aware that some sensory practices may require the use of attribute references (anchors) when training the assessors.
