Standard Guide for Screening and Training of Assessors and a General Approach for the Sensory Evaluation of Oral Care Products: Toothpaste and Toothbrushes

SIGNIFICANCE AND USE
5.1 The approaches to the evaluation of toothbrushes and toothpaste recommended in this guide can be used to assess the sensory characteristics of toothpaste in use and after use (or a series of uses). This guide is meant to address the evaluation of standalone toothbrush and toothpaste products and does not address packaging, product/package interaction, dispensing, or overall clinical effect or benefit of the product. The procedures outlined in this guide are to be used by assessors that have been specifically screened for sensory and descriptive ability and trained in the evaluation of toothbrushes or toothpaste or both. The procedures described in this guide can be used to guide product development within a manufacturer and communicate information regarding the product to the consumer through the media or on product packaging.
5.2 Additionally, language and ideas from two additional ASTM International sensory guides (Guides E1490 and E2082) as well as the Lexicon for Sensory Evaluation: Aroma, Flavor, Texture, and Appearance (DS72-2ND)4 are used throughout this guide.
SCOPE
1.1 This guide provides guidelines for the selection and training of expert assessors for the sensory evaluation of toothpaste and toothbrushes as well as a basic framework for the sensory evaluation of the same. Sensory evaluation of toothpaste and toothbrushes can be used to define the sensory attributes of the products and then to measure those attributes quantitatively for the purposes of new product development, product optimization, competitive benchmarking, and claims substantiation.
1.2 A general framework for both toothpaste and toothbrush descriptive analysis is provided to guide the reader in the design and execution (including sample preparation and presentation, facility and testing environment, and specific evaluation protocols) for such evaluations.
1.3 This guide provides suggested protocols and approaches to the evaluation of the indicated products/samples and in no way excludes any alternate approaches that may be effective in providing such perceptual evaluations.
1.4 This guide does not address other oral care products including, but not limited to, whitening agents, oral rinses, mouthwashes, dental flosses, denture adhesive, floss picks, or other oral care products.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Sensory Evaluation of Axillary Deodorancy

SIGNIFICANCE AND USE
5.1 The procedures recommended in this practice can be used to clinically assess axillary deodorant efficacy of personal care products.
5.2 This practice is applicable to the product categories which include deodorant and toilet soap bars, liquid bath soaps and gels, deodorant sticks, antiperspirants, creams and lotions, body talcs, and aerosol and pump delivery deodorants, antiperspirants, and body colognes.
5.3 Procedures of the type described herein may be used to aid in the communication of efficacy within and between manufacturers and to the consumer through the various public communications media. Guidelines are suggested due to the need to determine the relative or absolute performance of experimental materials or of commercial products.
5.4 These procedures may be used by persons who have familiarized themselves with these procedures and have had previous experience with sensory evaluation.
5.5 This practice provides suggested procedures and is not meant to exclude alternate procedures which may be effectively used to provide the same clinical result.
SCOPE
1.1 This guide provides procedures which may be used in the design and analysis of studies to quantitatively assess the intensity of human axillary odor for the purpose of substantiating deodorant efficacy of personal care products.
1.2 This guide includes protocols for the selection and training of assessors, selection of subjects, experimental design, and statistical analyses. This practice is limited to assessment of axillary odor by trained assessors. Self-evaluation protocols are valid for selected sensory tasks but may be less sensitive.
1.3 With respect to the source of axillary odor, three groups of secretory glands are present in the axillae which participate to a greater or lesser extent in its production—eccrine, apocrine, and sebaceous. Axillary odor has been primarily ascribed to the apocrine gland secretion (1) .2 Body odor intensity has been correlated with the volume of the secretory portion of the apocrine gland (2) and the density of the glands.
1.3.1 Apocrine glands are found primarily in the axillary vault in conjunction with axillary hairs (3). Pure apocrine sweat is sterile and odorless and axillary odor results from degradation of apocrine sweat by resident skin bacteria  (4). High bacterial populations are found in moist regions of the body, especially in the axillae, providing the appropriate environment for growth (5).
1.3.2 Eccrine glands keep the axillae moist through thermally and emotionally induced secretions (6).
1.3.3 The sebaceous glands excrete higher molecular weight lipid materials which absorb and retain the volatile materials resulting from bacterial action (7) . The aerobic diphtheroids are able to produce the typical acrid axillary odor and the micrococcaceae produce an isovaleric acid-like odor when incubated with apocrine sweat (8). Therefore, the most undesirable component of axillary odor is caused by degradation of apocrine sweat by particular bacteria normally found in the axillary vault.
1.4 Personal care products are sold and used primarily for their ability to reduce the perception of body odor not only by the individual using the product but also by individuals within the scope of contact. Deodorant protection may be achieved by these products through various modes of action. Antiperspirants achieve their primary efficacy by means of the action of inorganic salts on the eccrine gland production of sweat. Antimicrobial agents achieve deodorancy by inhibiting the growth and activity of the microflora in the axillary vault thus reducing the microbial decomposition of sweat and the consequent production of body odor. Absorbents function either by “binding” available moisture or malodorous substances. Fragrances are effective by altering the perception of malodor and increasing the degree of “pleasantness.” Other modes of control become important from time...

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

SIGNIFICANCE AND USE
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 s...
SCOPE
1.1 This guide covers standard procedures for the quantitative sensory assessment of perceived olfactory intensity of malodors for the purpose of assessing the malodor reduction efficacy of consumer products including, but not limited to, air care, fabric care, home care, pet care, and similar products.
1.2 This guide is not intended to cover axillary deodorancy; refer instead to Guide E1207.
1.3 Malodors may be from natural or synthetic sources.
1.4 This guide is a compendium of information or series of options that does not recommend a specific course of action. The user of this guide is responsible for identifying the most appropriate test design and using the appropriate statistical tools to address the experimental design.
1.5 This guide is designed to provide guidance in product formulation and new product development, and for quality control issues.
1.6 The scope of this guide does not include all guidance necessary to support claims. For further guidance the researcher may refer to Guide E1958. The usage of methods described in this guide can be used as part of a comprehensive claims support strategy for technical types of claims (such as claims that the product will create a sensory change when used on malodor). However, this guide does not address other important elements of the claim support strategy, including determining the statistical confidence requirements, or determination of the consumer relevance of the data obtained, as discussed in 1.7.
1.7 The testing of products designed to reduce malodors via sensory testing as outlined in the present Guide can yield technical support for products’ efficacy claims. The methods described in this guide—assesors with identified sensory acuity and trained, malodors that may be lab-created or synthetic, and controlled exposure to malodors in a controlled indoor environment—can deliver results with high internal validity. Internal validity refers to s...

Standard Guide for Two Sensory Descriptive Analysis Approaches for Skin Creams and Lotions

SIGNIFICANCE AND USE
5.1 The procedures recommended in this guide can be used to assess the sensory characteristics before, during, and after usage of skin care products.
5.2 This guide is applicable to product categories that include skin lotions and creams, facial moisturizers, hand lotions and creams, anti-aging lotions and creams, suntan lotions, personal repellents, and other skin care products.
5.3 Procedures of the type described herein may be used to communicate perceived sensory properties within and between manufacturers and to the consumer through the media. These guidelines are suggested to meet the need for ascertaining the performance of experimental and commercial products.
5.4 These procedures are to be used by assessors who are screened for sensory acuity, trained to use their senses to evaluate products, and in the procedures outlined by the panel method of choice, either technical assessor or consumer behavioral approach.
5.5 This guide provides suggested procedures and is not meant to exclude alternate procedures that may be effective in training skinfeel panels and providing sensory evaluation descriptions.
SCOPE
1.1 The objective of this guide is to provide procedures for two different descriptive analysis approaches that may be used to qualitatively describe the sensory attributes of skin creams and lotions and quantitatively measure their intensity, similarities, and differences over time. Descriptive analysis can be used to define the sensory experience of skin care products that can then be used to provide direction in product formulation, competitive assessment, ingredient substitutions, research guidance, and advertising claim substantiation.
1.2 Guidelines are provided to assist the reader in determining which approach best meets their research objectives, either the (1) technical assessor or (2) consumer behavior approach to language development and evaluation.
1.3 Guidelines are provided for the selection and training of assessors, defining sensory attributes, measuring intensities on rating scales, developing procedures for the manipulation of the product alone and the product on the skin, product handling, and evaluation of skin condition before testing.

ASTM E2613-23(Practice)

Standard Practice for Determining the Fungus-Eliminating Effectiveness of Hygienic Handwash and Handrub Agents Using the Fingerpads of Adults

SIGNIFICANCE AND USE
5.1 This in vivo procedure is designed to test the ability of hygienic handwash or handrub agents to eliminate fungal contamination from experimentally-contaminated hands. Since the two thumbpads and all eight fingerpads can be used in any given test, it allows for the incorporation of an input control (two), control for culturable cells of the test fungus remaining after the inoculum has dried (two), fungal cells eliminated after treatment with a control or reference solution (two), and up to four replicates to assess the fungus-eliminating efficiency of the formulation under test. No more than 100 µL of the test fungal suspension is required to complete one test.
5.2 Whereas this practice is designed to work with fungi, similar ASTM standards exist for testing against viruses (Test Method E1838) and vegetative bacteria (Test Method E2276).
5.3 The levels of culturable microorganisms left on hands after washing can be reduced further by drying the washed hands with paper, cloth, or warm air (5). A step for the drying of fingerpads after exposure to the control or test solution, therefore, has not been included to avoid fungal removal by the drying process itself.
5.4 This practice is not designed to test surgical hand scrubs or preoperative skin preps.
5.5 The level of contamination with culturable fungi on each fingerpad after the drying of the inoculum should be at least 104 CFU so that it would permit the detection of up to a 4-log10 reduction in the viability titer of the test organism by a test formulation under the conditions of this test. This in itself does not represent the product performance criterion, which may vary depending on the jurisdiction and the nature of the formulation being evaluated.
SCOPE
1.1 This practice is designed to assess the ability of hygienic handwash and handrub agents to reduce levels of fungal contamination on hands (3) . This practice is not meant for use with surgical hand scrubs (Test Method E1115) or preoperative skin preps (Test Method E1173).
1.2 Performance of this procedure requires the knowledge of regulations pertaining to human experimentation.3
1.3 The practice should be performed by persons with training in microbiology in facilities designed and equipped for work with infectious agents at biosafety level 2 (4).
1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 This standard does not purport to address all of the safety concerns, 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.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
