The Best Natural Soap: Our Picks

Guide: Questions you should ask yourself before buying a natural soap

What is a natural soap?

Every day we use soaps to wash our hands, but what are natural soaps? Natural soaps are soaps that are made from traditional processes and natural raw materials. They are therefore completely ecologically degradable.

The traditional process used to make natural soaps is called the cold stirring process. In this process, the oils or fats are mixed with a lye at cool temperatures.

Natural soaps are also completely free of chemicals, softeners, surfactants and preservatives. They are a purely natural product.

Only high quality oils and natural ingredients are added to the soaps. Natural soaps also contain perfumes, but these are always made from very high quality raw materials.

What are the advantages of natural soap?

In contrast to conventional soaps, natural soaps are completely free of additional substances and are made only from natural raw materials.

Unlike normal soaps, which are often made with animal fats because they are cheaper, natural soaps are made from only vegetable oils. Natural soaps are therefore also usually vegan.

What ingredients do natural soaps have?

Natural soaps are made from vegetable oils. These include, for example, rapeseed oil, olive oil or coconut oil. Animal fats are almost completely avoided. Only milk fat is contained in some soaps.

The soaps are then refined with other natural additives. These include, for example, other nourishing oils.

You can see which additives are particularly popular and what effect they have in the table below.

Additive effect
Oils such as avocado oil or jojoba oil for an additional caring effect
Natural colouring agents such as clay colouring
Milk such as sheep's milk or donkey's milk particularly caring effect such as soothing or moisturising
Fragrances and perfumes such as essential oils give the soaps their special scents

What are the advantages of buying a natural soap?

Natural soaps contain the substances listed above. We would like to give you a brief list of what is contained in a natural soap:

  • vegetable oils
  • natural colours
  • natural fragrances/high quality perfumes
  • natural additives
  • sometimes milk fats

Natural colours include earth tones as well as red and yellow shades. (Image source: / Akhil Chandran)

If it is a genuine natural soap, then it must contain the ingredients mentioned above. In addition, natural soaps must be free from the following substances:

  • chemical additives
  • Petroleum and mineral oil
  • Palm oil
  • artificial colours and fragrances
  • Preservatives

How much does a natural soap cost?

Natural soaps are slightly more expensive than conventional soaps. On average, they cost between €5 and €30. Their prices vary due to the additives used.

Natural soaps are also more expensive compared to other soaps because of their high-quality ingredients. Other soap manufacturers can only sell their soaps so cheaply because in many cases they only add animal fats, petroleum or preservatives.

What are the alternatives to natural soaps?

Alternatives to natural soaps are normal soaps and shower gels, which are also made from vegetable fats.

There are also many variants that contain similar additives and thus also have a positive effect on the skin. (Image source: / Deanna Alys).

However, there is no guarantee that these soaps do not contain some of the "non-ingredients" listed above.

So if you are looking for a natural product that is also ecologically degradable, natural soap is one of the best solutions.

If you are looking for a vegan soap, there are of course other soaps that are vegan. However, you should thoroughly inform yourself in advance and read through the ingredients.

Decision: What types of natural soaps are there and which is the right one for you?

If you want to buy a natural soap, there are two alternatives you can choose between:

  • Soap block
  • Liquid soap

Liquid soaps are usually in a bottle. Hard soaps, on the other hand, are the soap blocks.

Both soaps have their advantages and disadvantages. We would like to briefly point these out to you.

What distinguishes a soap block natural soap and what are its advantages and disadvantages?

Soap blocks are characterised by their mostly square shape. One of the biggest plus points of solid soaps is their minimal plastic packaging. Accordingly, soap blocks are more environmentally friendly.

Mostly, soap blocks also contain higher-quality substances as well as saponified fats and unsaponified fats. The latter are particularly moisturising for the skin.

One of the biggest criticisms of soap blocks is the hygienic aspect. Blocks of soap are often described as a bacterial sink, especially when several people use the same soap.

In addition, it is often the case that soap blocks have an alkaline pH value. In contrast, our skin is slightly acidic. This means that these soaps can dry out the skin.

In order to give you a better overview and to support you in your purchase decision, we would like to list all the advantages and disadvantages again:

  • more environmentally friendly
  • higher quality fats
  • real soaps
  • Bacteria-haven
  • often not ph-neutral
  • generally a little rougher on the skin

What distinguishes a liquid natural soap and what are its advantages and disadvantages?

In contrast to soap blocks, liquid soaps consist of synthetically produced detergents and not of saponified fats.

However, their advantage is that they are often pH-neutral and thus do not additionally destroy the acid mantle of the skin. In addition, synthetic detergents are considered more skin-friendly and are milder for sensitive skin.

Another advantage is the pumping station, which can reduce the number of bacteria. This speaks especially in favour of using liquid soaps when they are used by several people.

A clear disadvantage of liquid soaps is the packaging. Due to the high plastic content, liquid soaps are harmful to the environment.

In order to make a better comparison, you will find all the advantages and disadvantages at a glance below:

  • milder for the skin
  • more hygienic due to the pump station
  • environmentally unfriendly
  • no real soaps

Buying criteria: Use these factors to compare and evaluate natural soaps

When buying a natural soap, there are a few factors you should consider. This way you can be sure to find the right product for you. These are:

  • Ingredients
  • Effect
  • Scent/colours
  • Intended use

In the following, we would like to present these factors in more detail.


Personal preferences and tolerances should influence the purchase of a natural soap. We have already listed the individual ingredients in the first part of our guide.

Although natural soaps consist almost entirely of natural ingredients, it is still possible that one or the other ingredient may be less or more tolerated. Allergy sufferers in particular should find out exactly which additives have been added to the soaps.

Although the soap consists almost 100% of vegetable substances, milk fat is added in some soaps. This means that not all natural soaps are vegan. Therefore, people who lead a vegan lifestyle should read the ingredients again before buying.


In connection with the ingredients, the effect of the ingredients must also be taken into consideration when choosing natural soap.

All ingredients have a very special and often unique effect. If the wrong choice is made, undesirable side effects such as dry skin may well occur.

To counteract this effect, we would like to briefly list the effects of frequently used ingredients.

Ingredient Effect Suitable use
Olive oil Healing and anti-inflammatory effect Inflammatory skin problems and rheumatic complaints
Rapeseed oil Moisturising and mild effect Sensitive skin
Coconut oil Drying and degreasing effect Not for sensitive, delicate and dry skin
Shea butter softens the skin, protects it from drying out and accelerates the healing process of minor injuries Dry and stressed skin as well as stretch marks
Jojoba oil Anti-inflammatory effect, nourishes and regenerates the skin Suitable for all skin types, especially for acne
Avocado oil Is absorbed particularly quickly by the skin, moisturising Skin diseases such as neurodermatitis.E.g. neurodermatitis

However, there are countless other ingredients. In order to be fully informed about the effects of your soap, we recommend that you look up all the ingredients that we have not listed.


Just as with other soaps, the scent and colour factor plays an important role when buying a natural soap.

As mentioned in the guide, only natural and very high quality substances are used in natural soaps. This also applies to the fragrances and colouring agents. Essential oils are particularly popular.

Soaps are available nowadays in an infinite number of variations, especially the fragrances give the individual soaps a special touch. (Image source: / Kelly Sikkema)

There are countless different natural soaps. Here you can choose the type of soap of your choice. For particularly sensitive skin, there are also natural soaps that are free of any fragrances.

Intended use

When you buy a natural soap, you should bear in mind that there are different uses. Depending on what you need the soap for, there are different variants.

Typical uses are: Skin, hair, face or a mixture. Read the packaging and decide according to your needs.

Facts worth knowing about glycerine soap

How do you make natural soap yourself?

To make natural soap, you need high-quality oils and fats. Natural soaps consist of the salts of these vegetable oils.

  1. These oils and fats must first be liquefied in a pot. Then a lye (sodium or potassium) is added to the liquid oils/fats. Sodium or potassium lye pulls salts out of fatty acids and a soap-glycerine mixture is formed. This process is called "saponification" or "soap boiling".
  2. Now this mixture must be mixed with a mixing rod for 2-3 minutes to create a kind of "soap glue". At this stage, additional ingredients such as fragrances, petals or colours can be stirred into the soap.
  3. When you have added all the additional ingredients, you can put your "soap glue" into a mould. The "soap glue" must now rest for 24 hours. After 24 hours, the soap can be cut into smaller pieces and must then mature for another 3-4 weeks.

What is the shelf life of natural soap?

Natural soap is a purely natural product and therefore requires special care. If you want to keep your natural soap for a longer period of time, it should be stored in a dark, dry and cool place.

However, natural soap can be kept for quite a long time if stored correctly. In order to benefit from your soap for a particularly long time during use, you should allow your soap to dry again after use.

Note: Due to its natural glycerine content, the soap is slightly softer than conventional soaps.
