# When is bar soap better than shower gel? Bar soap can be a better choice in several situations:
Everyone who has ever found themselves in the cleaning products aisle of a store, trying to make sense of the flood of bottles, powders, and solid bars, knows how confusing that choice can be. It gets even more complicated when you want to shop both ecologically and effectively. Solid soap, loose washing powder, or liquid gel? Which form is truly gentler on the environment, and which will serve better in everyday life? The answers aren't always clear-cut, but once you understand the basic principles, making a choice becomes much more natural.
Interest in ecological household products has grown significantly in recent years. According to data from the European Commission, household consumption of cleaning and hygiene products accounts for a considerable share of total plastic waste in Europe. Switching to more sustainable alternatives is therefore not just a fashionable trend, but a genuinely meaningful step with a measurable impact. The question is: where to start and how not to get lost in it all?
Try our natural products
The form of the product matters more than you might think
At first glance, it might seem that what matters most is the composition — that is, whether the product contains harmful chemicals or, conversely, natural ingredients. That is of course important, but the form in which the product is available plays a crucial role in the ecological equation. Solid, loose, and liquid products differ from one another not only in their method of use, but also in the energy demands of their production, the amount of packaging required, and the carbon footprint associated with transportation.
Liquid products are still the most widespread format on the market. Detergents, shower gels, liquid soaps, and washing gels are popular thanks to their convenient application. However, liquid products have one major ecological drawback: they are largely made up of water. Experts estimate that a typical liquid shampoo or shower gel contains up to 80–90% water. This means we are essentially paying to transport water that is available directly from the tap. The plastic packaging in which liquid products come is then largely responsible for unnecessary waste.
Loose products — typically washing powders, baking soda, citric acid, or loose cleaning agents — fare somewhat better. Their advantage lies in their lower water content, but packaging plays a role here too. A paper box or cardboard sachet is more recyclable than a plastic bottle, yet it is still necessary to check whether the manufacturer actually uses recyclable or compostable materials. Loose products also tend to be more concentrated, so one box lasts longer than a comparable amount of liquid product.
Solid products — soaps, shampoo bars, solid conditioners, or solid cleaning tablets — are currently considered the most ecological option. The reason is simple: they are concentrated, require no plastic packaging, and their transportation generates fewer CO₂ emissions due to their lower weight. One solid shampoo bar can replace two to three bottles of liquid shampoo, while leaving a fraction of the waste. The British organisation Zero Waste Europe has long highlighted that switching to solid and packaging-free products is among the most effective steps an individual can take in their household.
Naturally, this does not mean that liquid or loose products are automatically a poor choice. It always depends on the specific product, its composition, packaging, and method of production. A mindful approach means not accepting one form as universally correct, but evaluating each purchase in a broader context.
How to genuinely choose ecological household products
Navigating ecological products is not always easy, particularly because the market is flooded with terms such as "natural", "organic", "eco", or "green" — and these expressions are not legally regulated in any way. Any manufacturer can essentially print them on packaging at will. So how can you tell what is genuinely gentle and what is merely cleverly designed marketing?
The first step is to focus on certifications. Products labelled with, for example, the EU Ecolabel, the German Blue Angel, or the Scandinavian Nordic Swan have undergone independent assessment and meet specific environmental criteria. These labels are not a guarantee of perfection, but they significantly increase the likelihood that the product is genuinely eco-friendly. Certifications such as COSMOS Organic or NATRUE function similarly in the area of cosmetics.
The second step is to read the ingredients. This applies particularly to cleaning products and cosmetics. Substances such as phosphates, microplastics, synthetic fragrances, or certain preservatives (such as parabens or triclosan) are problematic both for the human body and for aquatic ecosystems. Conversely, products based on plant-derived surfactants, baking soda, soap nuts, or citric acid are generally far gentler. Product ingredients can be verified using the INCI Decoder database, which explains individual ingredients in plain language.
The third factor is packaging. The ideal is a product with no packaging at all — such as a solid soap bought by weight or in a paper bag. If packaging must exist, it is appropriate to prefer glass, aluminium, or recyclable paper over plastic. And if plastic is unavoidable, then at least plastic labelled as recyclable or made from recycled material. Some brands also offer a refill system — the customer buys a bottle once and then replenishes it with concentrate, dramatically reducing the amount of waste generated.
The fourth aspect, which is often overlooked, is the concentration of the product. A highly concentrated product, where just a few drops are enough for washing a full load of dishes, is more ecologically advantageous than a diluted product that runs out within a week. Concentrated products are also more economical — even if their purchase price is higher, the cost per use works out lower.
Let us consider a concrete example: a family with three children uses on average two bottles of liquid dish soap, one bottle of shower gel, and one bottle of shampoo every week. Over a year, that amounts to approximately 200 plastic bottles. If this family switches to a solid dish soap bar, a solid shampoo bar, and a shower bar, they can reduce this number to a minimum — without having to sacrifice comfort or effectiveness. Precisely these small changes, multiplied across millions of households, have a real impact on the amount of plastic waste in the environment.
Local production also matters. A product made in the Czech Republic or neighbouring Germany has a significantly lower carbon footprint than one produced overseas and shipped to Europe by sea. Supporting local producers also has an economic dimension — it helps sustain jobs and develop the local economy. There are a number of Czech brands on the market that specialise in ecological household products and offer comparable or even higher quality than their foreign competitors.
As environmental activist and author Anne-Marie Bonneau once said: "We don't need a handful of people doing zero waste perfectly. We need millions of people doing it imperfectly." This thought is very liberating in the context of choosing household products. It is not about being perfect or switching to zero waste overnight. It is about making gradual, conscious decisions with every purchase.
The area of laundry deserves a chapter of its own. Laundry products are among those where switching to a more ecological option is relatively straightforward yet highly effective. Loose washing powders in cardboard boxes are generally gentler than liquid gels in plastic bottles. An even more ecological option is laundry sheets — thin, lightweight strips that dissolve directly in water and come in minimalist paper packaging. Their advantage lies not only in zero plastic waste, but also in their extremely low weight, which reduces emissions during transportation. Laundry sheets are still a relatively new product on the market, but their popularity is growing rapidly.
Let us not forget the universal helpers that many households already have at home but whose potential they do not fully exploit. Baking soda, vinegar, citric acid, and soap flakes form the basis for dozens of homemade cleaning products. By combining these simple ingredients, most common chemical preparations can be replaced — from cleaning the bathroom to degreasing the hob to polishing windows. Recipes are freely available and take just a few minutes to prepare. This path is not only the most ecological, but also the least expensive.
Choosing ecological household products is therefore a combination of several factors: the form of the product, its composition, its packaging, certifications, and its origin. None of these factors stands alone — it is only their combined assessment that makes sense. Solid products generally have the upper hand, but a quality loose washing powder in a paper box can be ecologically comparable to a solid laundry soap. Liquid products in a glass bottle with a refill system can be gentler than a solid product wrapped in unsuitable material.
The key is not dogmatic adherence to one form, but developing the ability to read between the lines — to understand what is written on the label and to distinguish genuine eco-friendliness from marketing greenwashing. The more a person practises this skill, the more natural and effortless such shopping becomes. And with every conscious purchase, they contribute to something that extends beyond the boundaries of a single household.
