“…Recently, we have extended this approach to evaluate the impact of consumer products ( Farage et al, 2010) . Consumer products can be broadly defined as products produced for, and purchased by individuals or households for use in their everyday lives, and they include personal care items, such as shampoo and hairspray, and household products, such as detergents and cleaning compounds.…”

“…The primary objective was to determine if the FQoL™ could be adapted for use in non-English-speaking geographies. In addition we wanted to compare overall responses, qualitatively, with those from the English-language version ( Farage et al, 2010) . The investigation was conducted in China using a similar design to the study conducted in the US.…”

The Farage Quality of Life™ questionnaire (FQoL™) was developed specifically to assess the impact of consumer products. The objective of this investigation was to achieve a Chinese language instrument. The FQoL™ underwent a forward and backward translation, with cognitive testing by 13 subjects. Slight modifications were made to the instrument, and an implementation study was conducted with 800 participants having a mean (±SD) age of 34.22 (±9.28) years. The subjects were randomly assigned to use 1 of 4 ultra absorbency pad products for the length of one menstrual cycle. Three pads (coded N, S and C) were products currently available on the retail market, a fourth (coded M) was an experimental product improvement on Product N. Subjects were asked to complete the FQoL™ once before (T1) and once after (T2) the start of their period, and the Least Square (LS) Means were determined. Within group comparisons for each item and FQoL™ subscale were conducted by comparing the LS Means for T1 vs. T2. Participants using Product N showed the highest number of significant (p<0.05) changes (11 items), demonstrating these subjects felt worse about items mainly in the subdomains for Emotions, Personal Pleasure, and Physical State. Participants using Product C showed significant changes in 7 items mainly in the subdomains for Emotion and Physical State. Participants using Product S and the experimental Product M showed significant changes in only 4 and 3 individual items, respectively. These were not associated with any particular domain or subdomain. Between group comparisons were conducted by comparing the LS Means for the T2 responses for each group. The group using Product N had LS Mean responses that were significantly worse than the group using Product M for the Emotion, Personal Pleasure and Physical State subdomains, the Energy/Vitality domain, and 2 individual items. The Product S group was worse than the Product M group for 2 individual items. The Product C group was worse than the Product M group for the Personal Pleasure and Physical State subdomains and 5 individual items. We found that the Chinese language FQoL™ detected changes in HRQoL during menstruation compared with before menstruation. Further, the measure was able to detect differences among groups of subjects using different menstrual protection products.

Manufacturers employ a stepwise approach to ensure the skin safety and compatibility of consumer products that are intended for contact with mucosal skin. The properties of the ingredients are evaluated fully, along with any available safety and skin compatibility information, to eliminate any chemicals that may be strong contact sensitizers or irritants. Contact sensitization potential is evaluated by applying a quantitative exposure assessment to each ingredient or component to determine if the extent of the expected exposure is likely to pose any risk of contact sensitization. Likely exposures are calculated using the manufacturer's unique knowledge of the intended product matrix, consumer usage patterns and measurements of particular exposure variables. If adequate safety assurance cannot be provided, further testing may be conducted. The skin compatibility and irritation potential of each ingredient is evaluated using existing test data, and experience from other products containing the same or a structurally similar ingredient. Once a finished product or formulation is developed, another round of assessments is conducted to ensure that no unexpected matrix effects negatively impact the skin compatibility profile. This may include clinical testing protocols involving single and multiple patch tests, and extended use testing, with visual and/or instrumental assessments. This approach to ensuring the skin safety of products has been used successfully for many decades, and adverse skin reactions to modern products are rare. The challenge for the future is to develop test protocols that will discriminate between products that are very similar in their favorable skin compatibility profile. Options to meet this challenge include testing protocols that will: (1) further exaggerate exposure conditions, such as the behind-the-knee protocol, (2) increase the sensitivity of scoring for irritant effects, such as with the use of instrumentation, and (3) quantitatively measuring additional endpoints, such as subjective sensory effects.
