In the past, while consumers were satisfied with soft soap and olive soap for personal care and housework, thanks to marketing and advertising, today we are convinced of their ineffectiveness and we are obsessed with hygiene. Over time, the consumption of these goods has become a common culture, an understanding and even an obsession. We started purchasing these products just for their attractive design, regardless of their harmful effects on our health and the environment. Furthermore, to achieve their primary purpose, advertisers and companies have trained consumers, especially women, to search for keywords such as "new", "improved", "enriched" and "advanced" which convey dubious messages. We women are convinced by the implicit messages given by advertising that we are not beautiful and clean enough, in other words, advertising promotes a lack of self-confidence by using ambiguous words and constantly pushes us to purchase these items that threaten our health and environment . In this essay I will examine how weasel words used specifically in the marketing of cosmetics and cleaning products persuade us and threaten our health and the environment. Weasel words are speech whose meanings are semantically changed by advertisers to avoid making a direct statement or promise. . Advertisers use ambiguous words to give an extremely sententious impression of what is said and written, but they only serve for unclear accusations, which we do not notice. However, linguist William Lutz has raised awareness of misleading words by analyzing how ambiguous words, equivocal words and false claims are used in advertisements. It states: "Advertisers use ambiguous words to appear... in the middle of the paper... they are not allowed to take advantage of consumers' lack of knowledge or experience. In conclusion, we have examined the misleading words related to skin care cosmetics personal and household cleaning products, which insidiously threaten our health and the environment. We encounter many ambiguous, carefully selected words in advertisements whose meaning they convey, which leads us to purchase these products awareness of words cleverly combined, we can see how advertisers can easily exploit women's consumerist behavior related to beauty and hygiene, which is one of their obsessions.
