Some sunscreens contain ingredients like octocrylene or benzophenone, which can be harmful not only to our skin but also to the environment. In this article, we examine these ingredients and explain the connections.

Octocrylene & Benzophenone: Problematic UV filters in focus

Octocrylene is a widely used UV filter, frequently found in sunscreens and anti-aging creams. Its function: to protect against UVB rays and stabilize other sunscreens. This sounds sensible at first, but the substance also has a downside.

Over time, octocrylene can decompose, especially if the product has been open for a while and reacts with oxygen. This can produce a compound classified as potentially carcinogenic: benzophenone. Therefore, it's important to pay attention not only to the ingredients of a sunscreen, but also to its shelf life and storage conditions.

Many people are unaware that their sunscreen can become problematic over time. It's not just the sun protection that matters, but also what happens to the ingredients as the cream ages. This is a point that is often overlooked, but it's truly important for your health.

What exactly is octocrylene?

Octocrylene is a chemical UV filter often used to protect the skin from UVB rays – the rays primarily responsible for sunburn and premature skin aging. At the same time, octocrylene ensures that other sunscreen filters in the formulation remain stable and can maintain their effectiveness for longer.

This ingredient is found not only in classic sunscreens, but also in day creams with SPF, lip balms, and even some hair care products. In short, octocrylene is present in many cosmetics and is therefore a daily companion for many, often without their knowledge.

What is benzophenone?

Benzophenone is a compound that can form when octocrylene degrades over time, especially if the sunscreen has been opened and exposed to air for an extended period. The problem: In animal studies, benzophenone has shown potential carcinogenic properties. It is also suspected of being an endocrine disruptor and affecting thyroid function.

That's precisely why more and more people are consciously choosing sunscreens without octocrylene, to avoid potentially harmful substances like benzophenone coming into contact with their skin in the first place.

Health and environmental risks in detail

Octocrylene and benzophenone have been criticized for some time now, and with good reason. The issue is no longer just about potential risks to our health, but also about their impact on the environment. New scientific findings are increasingly raising questions that are prompting a rethink.

The potential hormonal effects of octocrylene are a particular focus. Studies suggest that this UV filter can interfere with the hormonal balance, and since hormones control many key bodily processes, an imbalance can have far-reaching consequences. Furthermore, octocrylene can cause irritation in sensitive skin and is even suspected of triggering so-called Mallorca acne. This is further evidence that not every ingredient is suitable for every skin type, making conscious product selection all the more important.

Another critical aspect concerns benzophenone. This substance can form when octocrylene in sunscreens breaks down over time, especially in older or already opened creams. Benzophenone is classified by expert panels as "probably carcinogenic"—an assessment that should not be ignored.

Even though the data on humans is not yet conclusive, there are legitimate concerns. Initial indications suggest that benzophenone could not only increase the risk of cancer but also impair thyroid function. All the more reason, then, to take a close look when choosing sun protection.

And then there's the environment. When we go swimming, the ingredients in sunscreen end up in the water. Octocrylene and benzophenone are suspected of damaging coral reefs and accumulating in the marine environment. This affects not only corals, but also fish and other marine life. It's a cycle that concerns us all.

• Octocrylene can enter the body through the skin.

• Benzophenone may be present in higher concentrations in older products.

• Both substances can have negative impacts on the environment, especially on marine ecosystems.

For whom is sunscreen without octocrylene particularly important?

Not every skin type tolerates all ingredients equally well; this is perfectly normal. It's especially important to take a closer look at the ingredients if you have sensitive skin. For certain groups of people, it may be advisable to consciously avoid octocrylene, simply to prevent potential irritation or unwanted reactions from the outset.

Especially where protection and tolerability are paramount, every ingredient counts. Less risk, more skin comfort. This allows sun protection to be specifically tailored to individual needs.

Pregnant women, breastfeeding mothers and hormonal disorders

During pregnancy and breastfeeding, the body is in a particularly sensitive phase – hormone levels change, and many women are very conscious of what they eat, use, or apply to their skin. Even with existing hormonal imbalances, it can be advisable to avoid certain chemical UV filters – especially those suspected of affecting the hormonal system.

Because:

– The hormonal balance is particularly susceptible to disruption during this time.
– The potential effects on the unborn child or infant are a focus for many expectant and breastfeeding mothers.
Those who already suffer from hormonal problems often look for products that are as gentle and well-tolerated as possible.

Whether it's pregnancy, breastfeeding, or a hormonal imbalance – the decision to avoid potentially harmful ingredients like octocrylene is a personal one. But for many, it's reassuring to play it safe, especially during these phases of life. Choosing the right sunscreen is a small but important step in that direction.

Understanding INCI: How to identify questionable UV filters

The list of ingredients on cosmetic products, the INCI list, can be quite confusing. But with a little practice, you can identify problematic UV filters. Beware: Sometimes these substances hide behind names that aren't immediately recognizable.

Typical terms and synonyms

Octocrylene isn't always immediately recognizable as such, as it sometimes hides behind other names. A bit like a chameleon changing its color. Knowing the common names is a clear advantage and allows you to better assess what's really in the product when looking at the ingredient list.

You should keep these terms in mind:

– Octocrylene (this is the common INCI name)
– Octocrilene
– 2-Cyano-3,3-Diphenyl Acrylic Acid 2-Ethylhexyl Ester

Benzophenone is another such case. It can not only form from octocrylene, but sometimes also appear directly as an ingredient. Look out for names like:

– Benzophenone-1, -2, -3 (where benzophenone-3 is also known as oxybenzone )
– Oxybenzone

A close look at the INCI list is therefore worthwhile. Manufacturers are required to list all ingredients, and the better informed you are, the easier it is to choose products that truly suit you and your skin. Clarity creates confidence and a good feeling when applying cream.

Tools for quick ingredient testing

Don't worry – you don't have to memorize every complicated ingredient. Luckily, there are handy tools to help you with just that. Imagine having a small digital assistant that tells you in seconds whether a product contains any questionable substances. Sounds good? It really exists!

These tools will make your life easier:

– Apps: There are smart apps that you can easily download to your smartphone. Scan the barcode or enter the product name and you'll get an assessment of the ingredients. Ideal for on the go and super easy to use.

– Online databases: If you want to delve deeper into a topic, many websites offer extensive ingredient databases. Simply enter the name and you'll find out how an ingredient is rated and what you should pay attention to.

– Checklists: Some consumer portals or blogs offer clear lists of the most common critical ingredients. You can print these out or save them on your phone – perfect as a quick decision-making aid when shopping.

With tools like these, you'll become an INCI pro in no time. The effort is minimal, the benefits are huge. Especially when it comes to your skin and health. And let's be honest: it feels good to know exactly what you're putting on your skin. Safe alternatives: These UV filters are considered safe.

There's good news: you don't have to forgo sun protection just because you want to avoid octocrylene and benzophenone. A number of UV filters are considered safe and still offer the necessary protection. These alternatives are often a good choice, especially if you have sensitive skin or simply want to play it safe.

Research in this area is constantly advancing. New and improved formulations are continually being released that not only provide effective protection but are also pleasant on the skin and leave no unwanted residue. It's therefore worthwhile to stay informed and carefully examine the ingredients.

Conclusion: Better to do without octocrylene

So, what's the takeaway? Sunscreen is super important, no question. But it's really worth taking a closer look at what's in it. Octocrylene and benzophenone might not be the best friends for our skin or the environment. Sure, the risk of skin cancer is much higher if you don't protect yourself at all. But if there are alternatives that work just as well, why not? There are so many good products without these substances these days. Just keep your eyes open and check the ingredients. Then you can enjoy the sun without having to worry.
