SUMMARY Cosmetic products include a wide range of products that play an important role in human lives. An increasing number of people use them every day for cleaning, nurturing and improving the appearance, and the demand for these products is growing every year. Since these are products that are used every day, and it is extremely important to ensure the safety of consumers and provide them with the necessary information. To regulate the field of cosmetic products, a single European regulation has been adopted, which prescribes in detail the placing of cosmetic products on the market. This paper will describe the specific requirements that cosmetic products must meet to be properly found on the market, and their impact on the attitudes of users of these products. The survey provided results on consumer information and their attitudes about the labelling of cosmetic products in Croatia. OBJECTIVES Transparent label of product content and properties becomes not only a legally obligatory part of placing a product on the market but also a condition of its good perception by consumers and affects their positive attitude towards product quality and its use. The aim of this paper is to provide an overview of mandatory product information when placing a cosmetic product on the market and through an online questionnaire to examine the extent to which average consumers in Croatia are familiar with the data labelled on the product, how important these data are when choosing a product, whether they lack some information on the product label. METHODS To collect relevant data, the literature was searched, as well as reports and guidelines of leading regulatory bodies and agencies in the field of cosmetic products. The search selected the most relevant articles, which were then processed and included in the paper. The keywords used in the search were: "cosmetic product", "labelling", "cosmetic product regulation", "safety", "claims", "consumer attitudes". To be able to contribute to the work by gaining insight into the attitudes and beliefs of consumers about the data on the label, an anonymous online survey of consumers in Croatia was conducted. The questionnaire was created using the Google Forms tool and the collected data were processed with the same tool. 105 respondents from Croatia participated in the survey. Respondents were selected from private and business contacts to obtain as representative sample as possible. The questionnaire was sent to the selected respondents without restriction, via e-mail with a request to further forward the survey. RESULTS The results are presented through the regulatory aspect and through the analysis of the survey results. Cosmetic products are regulated at the EU level, so that all member states have harmonized regulation. The entire process of cosmetic product development from the original formulation to the placing on the market of the finished product and its further monitoring and notification in case of side effects is regulated and determined by law. The analysis of the survey results provided insight into the importance of product information to the consumer. The obtained results showed that 75% of the respondents read the label of product. Almost 45% of respondents will replace a product on which they cannot find the requested information with another one, on which the requested information is stated. CONCLUSION Cosmetic products are a large group of products that are used every day and it is extremely important to provide consumers with product safety and all the necessary information. The regulations are prescribed and regulated, but they are continuously updated. It is the obligation of the manufacturer to meet the requirements set through the regulatory framework. It determines the requirements for production, but also the conditions before placing on the market, as well as monitoring the product that is already on store shelves. Marketing advertising is one of the ways to communicate with the consumer, however, here too it is necessary to follow the regulations and permitted ways of communication. Analysing consumer attitudes can be crucial when designing a marketing campaign.
