Standard Guide for Assessing the Efficacy of Consumer Products in Reducing the Perception of Malodor

Importancia y uso:

5.1 The purpose of this guide is to assess the ability of consumer products to reduce malodor intensity from a control state. Several experimental hypotheses are possible, depending on the objective of the test. Possible objectives with respective hypotheses are given in Appendix X1.

5.2 Many consumer products are sold commercially with the intent of providing a means of improving the odor quality of a volume of air, or the odor quality of a substrate such as fabric or household surfaces, relative to some existing environmental condition. In the case of air care products, this typically involves the application of an odorous substance into the air space by means of some active or passive mechanism (for example, by spraying, or by evaporation). This procedure is also applicable to other mechanisms of odor reduction (for example, air filtration, chemical reactions, etc.).

5.3 Selection of representative malodor sources is of critical importance. The malodor source must be readily available and of a consistent odor quality. A reasonable malodor source should be chemically and aesthetically correct. The experimenter and client must agree upon the appropriateness of a malodor source before further details of the test design are worked out. Experimental variation will be reduced by using uniform malodor sources. Information collected on malodor reduction will thus be more comparable from experiment to experiment and from laboratory to laboratory.

5.4 The procedure recommended can be used for assessment of the malodor reduction and elimination efficacy of consumer products including: air fresheners, air filtration products, aerosol/spray and continuous/solid air freshener products, candles, fabric care products including detergents and fabric enhancing/conditioning products, surface care products including carpet care products, surface cleaning products such as sprays etc., pet care products, and other products intended to deliver a malodor reduction benefit. It should be noted that while product evaluations are fundamentally the same, different treatment or measurement techniques may be necessary because of inherent differences in the product delivery systems.

5.5 Temporal Aspects—The procedures herein can be applied to evaluate temporal aspects of product performance, such as determining how long it takes for a product to work, or how long it takes malodor to develop (for example, after treatment, etc.).

5.6 These procedures can be used to assess efficacy against any standard malodor, regardless of the mechanism of odor removal.

5.7 This guide is designed to provide guidance in product formulation and new product development, and for quality control issues.
