Assessing the Role of Shape and Label in the Misleading Packaging of Food Imitating Products: From Empirical Evidence to Policy Recommendation

The effect of information about hazardous chemicals in consumer products on behaviour - A systematic review

Exposure to hazardous chemicals in consumer products poses significant risks to personal health and the environment, and the combined effects may be negative even if each individual exposure is low. This necessitates informed and effective policies for risk reduction. This systematic review aims to identify and analyse existing evidence on how consumer preferences, product use, and product disposal are affected by information on harmful chemicals in consumer products and by price interventions. The review is conducted according to the PRISMA 2020 guidelines, synthesises forty-eight scientific articles on the relationship between information and consumer responses. No corresponding studies on the effects of price interventions were found. A large share of the identified articles focused on household chemicals, where warning labels are common, while less has been published on "everyday products" where the presence of hazardous chemicals is less clear to consumers. Effects of information on hazardous chemicals on consumer behaviour are highly contextual and dependent on the type of product, consumer behaviour and what kind of label is used. Warning symbols are effective in communicating a general warning of a potential danger, although consumers often misinterpret specifics regarding the exact nature of that danger or what means should be taken to minimise it. Informational texts are more informative but are also often missed or quickly forgotten. Consumer willingness to pay for safer products is generally positive but low. Additional research on how consumers react to information and price signals on chemical hazards is needed to improve policy design.

Childhood poisonings: Effects of ambiguous product characteristics on preschool children's categorization of household chemicals

This study investigated preschool children's categorization and risk perception of products with ambiguous product characteristics (e.g., food-like packaging). These characteristics make it difficult for preschool children to categorize household chemicals correctly. This, therefore, increases the risk of unintentional poisoning. We hypothesized that ambiguity arises from different product characteristics, such as the type of packaging, the products' scent, or the packaging's color and transparency. In four behavioral tasks, N = 108 preschool children (M = 43 months, SD = 3) categorized different products and household chemicals with various types of packaging, colors, and scents. Individually wrapped dishwasher tablets were more likely to be categorized as edible than unwrapped ones. Furthermore, children who had interacted with any type of dishwasher tablet in the last 6 months performed better in identifying dishwasher tablets, regardless of packaging type. Household chemicals with a fruity scent were more likely to be categorized as drinkable than those with a chlorine scent. Finally, the children considered black bottles more dangerous and preferred them less than bottles of a different color. In contrast, bottle transparency generally did not seem to affect risk perception and preference. These findings confirm that ambiguous product characteristics influence children's categorization of unknown products and, thus, their risk perception and decision-making. Manufacturers and caregivers are advised to reduce the ambiguity of household chemicals by designing more neutral product packaging and choosing products with more neutral elements, respectively.

Biocidal products: Opportunities in risk assessment, management, and communication

In the coronavirus disease 2019 era, biocidal products are increasingly used for controlling harmful organisms, including microorganisms. However, assuring safety against adverse health effects is a critical issue from a public health standpoint. This study aimed to provide an overview of key aspects of risk assessment, management, and communication that ensure the safety of biocidal active ingredients and products. The inherent characteristics of biocidal products make them effective against pests and pathogens; however, they also possess potential toxicities. Therefore, public awareness regarding both the beneficial and potential adverse effects of biocidal products needs to be increased. Biocidal active ingredients and products are regulated under specific laws: the Federal Insecticide, Fungicide, and Rodenticide Act for the United States; the European Union (EU) Biocidal Products Regulation for the EU; and the Consumer Chemical Products and Biocide Safety Management Act for the Republic of Korea. Risk management also needs to consider the evidence of enhanced sensitivity to toxicities in individuals with chronic diseases, given the increased prevalence of these conditions in the population. This is particularly important for post-marketing safety assessments of biocidal products. Risk communication conveys information, including potential risks and risk-reduction measures, aimed at managing or controlling health or environmental risks. Taken together, the collaborative effort of stakeholders in risk assessment, management, and communication strategies is critical to ensuring the safety of biocidal products sold in the market as these strategies are constantly evolving.

Protecting the children -a virtual reality experiment on consumers' risk perceptions of household chemicals

Warnings on the labels of hazardous household chemicals (e.g. warning pictograms and use instructions) should create risk awareness and thus encourage safe storage, handling and disposal. However, scientific findings have called into question the effectiveness of warnings to prevent accidents, albeit mostly based on consumers' self-reports. This study aimed to contribute to existing data on household chemicals and consumer safety by applying a novel observational method using virtual reality (VR). The study participants (N = 119) were observed after receiving a task to childproof a virtual apartment from various interactable neutral and hazardous objects (i.e. knives, lighters and household chemicals with and without warnings) that were placed in the virtual apartment. For the analysis, the object placement (i.e. accessible or inaccessible to the children) and the level of interaction with the objects were coded, and the observational data were supplemented with data gathered through a questionnaire. The results showed that most hazardous household chemicals were moved to spots that were inaccessible to the children without any interactions of the participants with the warnings. Instead, they used their pre-existing knowledge and intuitive strategies to judge the objects' risks. These potentially misleading intuitive strategies should be increasingly considered in the regulation of hazardous household chemicals. This study also discussed the use and limitations of VR for the observation of human behaviour and decision making under uncertainty.

Seeing household chemicals through the eyes of children-Investigating influential factors of preschoolers' perception and behavior

INTRODUCTION

Children who encounter household chemicals run the risk of unintentional injury. The aim of this study was to understand which factors heighten children's attention or misguide their decision-making concerning household chemicals. We hypothesized that certain product attributes (i.e., label, packaging, closure types), storage context, and parental beliefs play a role in this setting.

METHOD

We conducted a laboratory study with N = 114 children (M = 45 months, SD = 6.5) and their parents (M = 38 years, SD = 4.92). Children completed a series of behavioral tasks in which they had to choose between products with different attributes, identify products in different storage contexts, and sort household chemicals.

RESULTS

The results confirmed that the children preferred products with cartoon-style labels compared to products without such labels. However, children's decision-making did not differ for products with different closure types (child-resistant vs sprayer-type closures). Regarding the storage context, our results showed that the children particularly struggled to identify dishwashing tabs when they were stored with other food items rather than household chemicals. In terms of parental beliefs, our study found that parents rated more household chemicals as child-safe than their children did.

PRACTICAL APPLICATION

Parents should buy household chemicals with neutral labels and pay attention to how their household chemicals are stored. Manufacturers should consider potential adverse effects when developing new product designs.

The exploration of size and toddler interaction with liquid laundry detergent capsules

Liquid laundry capsules have been involved in multiple poisoning incidents with young children in the home. There are a range of contributing factors for these incidents, including influences from industry, culture, home environments, and parenting/supervision. There also are influences from children’s behaviour and decisions in reaction to potential hazards. Previous research examined the influence of capsule product appearance and colour on children’s behaviour around hazardous household items, but little research examines the influence of product size. This research explored if differences in the size of liquid laundry capsules result in different levels of toddler interaction. We compared two commercially available capsule designs that are identical in physical appearance but differ in physical size. Our research was conducted using three studies: Study 1, forced-choice test in an out-of-context laboratory setting; Study 2, an ecologically-valid, simulated real-world setting replicating a home laundry cabinet with a container of capsules left open; and Study 3, a second ecologically-valid study replicating a home laundry cabinet, this time with a capsule left outside its container. Capsule interaction was measured by grasping choice among samples of 156 toddlers ages 9–36 months. The same sample was used for Studies 1 and 2, and a second identically sized sample recruited for Study 3. Results from Study 1 indicated toddlers selected the small (49.8% selection) and large (50.2%) capsule with nearly identical frequency. Study 2 largely replicated Study 1: Toddlers selected the small capsule or container of small capsules 26.8% of the time and the large capsule or container of large capsules 22.3% of the time. Study 3 also replicated previous findings: Toddlers selected the smaller capsule 18.0% of the time and the larger 19.2%. We discuss study results, which suggest no appreciable difference in toddler’s grasping choice to smaller versus larger laundry capsules.

Neuromarketing Applied to Educational Toy Packaging

This research work comes in response to the question of which aspects are more relevant for consumers when purchasing educational toys as opposed to other toys that are focused solely on leisure. This empirical research focuses on an educational toy distributed in Spain by the Educa brand (Conector family, reference "I learn English"), which is the product best-selling product of its brand in this area, and analyses how consumers make decisions concerning this product in relation to other products designed by competitors. The research looks into customer reactions while looking at these products, measuring brain activity generated by different aspects of product design and its influence on choice. The aim of the present study was to propose a model that optimizes the design of educational toy packaging. Through the use of neuromarketing techniques -attention through eye tracking, and emotion using galvanic skin response- as well as qualitative research techniques, the objective of this research is to determine the motivations in the processes of buying educational toys. The packaging design elements analyzed are brand, product family, toy name, recommended age, game image, number of questions/topics, and additional texts. The results suggest that the most important elements are the graphic details of the packaging, obtaining a perception of a higher educational level as more questions are addressed by the game. The simultaneous combination of qualitative techniques monitored with galvanic skin response (neuro-qualitative study) allows additional conclusions to be aligned with the end user of the product, including a prominent social component when the product is purchased as a gift for a third party.

Barriers to the safe use of chemical household products: A comparison across European countries

Chemical household products, such as cleaning and washing products or pest control and garden chemicals, are frequently involved in poisonings in private households. Consumer research has identified a number of barriers that impede the safe use of these products, ranging from unfamiliarity, to misconceptions and a lack of risk perception, to behavioural or situational barriers. This study aimed at investigating these barriers for consumers in eight European countries. Participants from eight European countries were recruited and asked to fill out an online questionnaire on their familiarity with hazard pictograms, perceptions and self-reported behaviour (Total: N = 5631, Austria: N = 731, Switzerland: N = 698, Germany: N = 711, France: N = 708, Italy: N = 695, Poland: N = 693, Sweden: N = 682, UK: N = 713). Across all countries, the lowest consumer familiarity was found for the meaning of the pictogram for "health hazard" (65% indicated having never seen it before). Small-sized differences between the eight countries were observed regarding people's familiarity, perceptions and self-reported behaviour. The results suggest that people apply hazard-related as well as product- and marketing-related strategies to judge the dangerousness of a chemical household product. These findings suggest a number of starting points for risk regulation and communication regarding hazardous household chemical products. Further, the results suggest that positive outcome expectancies and rules of thumb for judging the risks of a chemical household product are particularly relevant for people's self-reported safe use of chemical household products.
