Chemistry, Fear, and Public Misconception

The phrase ‘This product is chemical-free’ frequently appears in advertisements for food, cosmetics, soap, and household goods. Without a second thought, many people regard such a label as a guarantee of safety. Conversely, when reading a list of ingredients filled with names like sodium benzoate, ascorbic acid, or potassium sorbate, quite a few consumers immediately feel uneasy. The more foreign the name of a substance, the greater the suspicion towards it.

Ironically, from a scientific perspective, the claim of being ‘chemical-free’ is actually impossible. The water we drink is a chemical compound. The oxygen we breathe is a chemical element. Table salt, sugar, vitamins, proteins, and even the human body itself are entirely composed of various chemical compounds. Without chemistry, life would never have existed.

So why does the word ‘chemical’ sound frightening? Researchers call this phenomenon chemophobia, a tendency to view chemicals as synonymous with danger, especially if they originate from a synthetic process rather than being obtained naturally. Society does not actually hate the science of chemistry. People utilise its results every day, from medicines, fertilisers, and detergents to mobile phones. What is feared is the word ‘chemical’ itself, or more specifically, chemical substances.

This perception is not without cause. History records various tragedies involving chemicals, from industrial accidents like the 1977 Seveso disaster in Italy and the 1984 Bhopal tragedy in India, to environmental pollution caused by the pesticide DDT. There is also the misuse of hazardous materials, such as the use of formalin in food, mercury in illegal cosmetics, and acid attacks against law enforcement officers and activists. This collective experience has shaped the perception that chemicals are synonymous with threat and danger. Such concern is understandable, but problems arise when this fear develops into a rejection of almost everything labelled ‘chemical’, without distinguishing between what is genuinely risky and what is safe to use.

In the current era, social media reinforces this tendency. Almost daily, videos or narratives circulate claiming to have found ‘dangerous chemical substances’ in food, drinks, or cosmetics. Compound names that sound complicated are presented as if they are proof that a product is hazardous. The harder a substance’s name is to pronounce, the easier it is to suspect. Yet chemical names often sound unfamiliar. Ascorbic acid is nothing other than vitamin C. Sodium chloride is table salt. Even water, when introduced as dihydrogen monoxide, once made many people believe they were dealing with a dangerous substance. This simple experiment shows that our perception is often influenced by terminology, not by the actual properties of a substance.

Another way of thinking that reinforces chemophobia is the belief that everything natural is certainly safer than anything synthetic. Products labelled ‘natural’, ‘organic’, or ‘chemical-free’ are often more sought after. There is nothing wrong with choosing natural products, but nature is not always synonymous with safety. Arsenic, cyanide, and various mushroom toxins are natural compounds. Conversely, many synthetic drugs have saved millions of lives over decades. When we consume a vitamin C tablet, our body cannot distinguish whether the vitamin C came from an orange or was produced in a laboratory if the chemical structure is identical.

Another common misunderstanding is assuming that the mere presence of a substance automatically means it is dangerous. In toxicology, there is a classic principle: ‘the dose makes the poison’, meaning the dosage determines whether a substance becomes toxic. Table salt, often added to cooking, can harm the body if consumed excessively in a short time. Conversely, many substances often perceived as dangerous are actually safe to use as long as their levels remain within limits established by scientific studies. Unfortunately, this concept often escapes public conversation.

In the age of social media, fear often spreads faster than knowledge. Digital algorithms tend to promote content that is shocking, emotionally provocative, and easy to share. A title like ‘Five Deadly Chemicals in Your Kitchen’ is far more likely to attract attention than an explanation of toxicology, exposure, or risk assessment. As a result, society is flooded with anxiety-inducing information that lacks context.

Thus, the greatest challenge today is not the existence of chemicals, but the ability to distinguish correct information from misleading content. Scientific literacy becomes increasingly important when anyone can produce and disseminate information to millions of people via a mobile phone. A critical attitude towards the products we consume must be maintained, but being critical is different from fear based on misconception. The public has the right to know if a substance is genuinely dangerous or used improperly, and equally, the right to obtain information explaining why a substance is declared safe, how risks are assessed, and why dosage and exposure are the determining factors. Ultimately, what we need is not a world without chemicals—because such a world has never existed—but a society capable of understanding chemicals more rationally. In this era of information overload, the greatest threat is not merely the chemicals we use, but our inability to distinguish between fact and fiction.
