Why do you have a Soap Allergy? What are Promising Solutions?

Why do you have a Soap Allergy? What are Promising Solutions?

From the 70s my parents went on holiday in Spain and brought Maja soap back home with them. The scent of that soap still reminds me of my sunburnt mother who blissfully unwrapped her soap.

The scent was too flowery for me, but what I liked was the paper packaging. I don’t have a soap allergy, but I want sustainable products, including their packaging. Nowadays there is hardly any soap available in Spain that is wrapped in paper. Even in the Eco store, the Marseille soap is wrapped in plastic.

I usually buy my soap at an old crafts market, if I happen to bump into it. Those are usually barren or have a banderole of paper around them. The best soap I have found so far is honey soap, which was a present from a nice beekeeper in the centre of Spain.

A soap allergy is a nuisance

People like soap that foams. This gives a sense of better cleaning. Foam is caused by sodium lauryl sulfate (SLS), which can also trigger allergies.

Compositions of soap

Ever since I watch closely at the nutrient lists of the foods we buy, I also pay attention to the composition of soap, toothpaste, detergent, etc. And maybe the ingredients that mainly consist of numbers are not bad at all, but I have developed a distrust against them.

This is for example the composition of Maja Soap: Sodium Palmate, Sodium Cocoate, Zea Mays Starch / Zea Mays (Corn) Starch, Parfum / Fragrance (Anis Alcohol, Citral, Citronellol, Coumarin, Eugenol, Geraniol, Limonene, Linalool), Glycerin, Paraffinum Liquidum / Mineral Oil, Cera Alba / Beeswax, Butyrospermum Parkii Butter / Butyrospermum Parkii (Shea) Butter, Aqua / Water, Sodium Chloride, Citric Acid, Tetrasodium EDTA, CI 77891 / Titanium Dioxide, CI 26100 Red No. 17 (D&C), CI 47000 Yellow No. 11 (D&C), CI 61565 Green No. 6 (D&C).

Even Sanex, which is a brand especially for sensitive skin, has a long list containing: Aqua, Glycerin, Sodium Laureth Sulfate, Cocamidopropyl Betaine, Coco-Glucoside, Sodium Chloride, Sodium Lactate, Lactic Acid, Sodium Benzoate, Sodium Salicylate, PEG-120 Methyl Glucose Trioleate.

A possible cause of your soap allergy: Sodium Lauryl Sulfate

Many soaps contain Sodium Lauryl Sulfate (SLS), which some say is carcinogenic, and others that it “only” causes skin irritation. The reason for adding SLS is that it foams so nicely.

The foaming makes it difficult to rinse it all off and can stay on your skin for days. And even penetrate it with negative influences on your kidneys and liver. In addition, SLS reduces skin fat from oils, causing your skin to dry out.

SLS is not only found in soap, but also in toothpaste, shampoo, shaving cream, shower gel, cleaning products, and detergents. There is also SLES – Sodium Laureth Sulfate – which appears to be slightly milder than SLS.

Consumer safety

The food and drug organizations still consider SLS and SLES to be safe enough for use by consumers. Yet it is a fact that more and more people are allergic to all kinds of products.

Make your own soap

If you don’t want to take any chances, make your own soap. That will foam less, but cleaning has nothing to do with foaming.

There are 2 ways to make your own soap:

  • Make everything yourself. This is more of a hassle, because you have to work with lye, but it seems to be an easy process;
  • Use a soap base, to which you add olive oil and coconut oil and other natural ingredients.

The best part of it – because it’s fun – is working with moulds, so that the soap takes on all kinds of shapes. Great to use as presents.

Choose 100% silicone moulds if you want a sustainable product. Silicons look like plastic, but they are not. The silicone production process is chemical, but the raw materials include sand or pebble.

Sustainable and organic

Use natural or organic ingredients as much as possible. For example, if you want a nice scent, add an organic essential oil. You can also add coffee for a scrub effect.

Dyes to give the soap a colour are offered on DIY-soap-making websites. I quit my ceramics studio because I no longer wanted to work with toxic heavy metals such as chromium oxide. So I would advise against dyes based on metals.

Textiles can be coloured with vegetable substances like onion peels. I don’t know (yet) if that is also possible with soap. The colour may be too faint. Do you know it? If so, please let me know in the comment box below.

Organic soap is milder and softer than the usual soap. It also hydrates better, which prevents your skin from ageing quickly.

Shampoo Tip

You can use your homemade soap as a shampoo. Rinse with a few drops of apple cider vinegar and you don’t even need to use a conditioner anymore.

Types of natural soaps

Natural soap against a soap allergy: Marseille soap

If you don’t have the time or feel like making your own soap, you can opt for a natural soap.

Most natural soaps take their name from the region where they come from. The composition is a combination of potassium salts with higher carboxylic acids, glycerol, citric acid and sodium chloride. (Doesn’t sound natural at all, don’t you think? Yet it is.)

Due to their antibacterial properties, these soaps are suitable for sensitive skin, oily skin, acne or a skin type that is prone to allergic reactions.

If you are looking for a soap with a specific name, pay attention to the composition. The names are not protected like for example the name Champagne is. They are hard soaps, which can be recognized by:

  • Contain no more than 4-5 natural ingredients;
  • Have a 100% natural composition, without preservatives and without cleaning agents;
  • Not much foaming, although some do;
  • Do not contain animal fats, but vegetable oil, making them vegan;
  • Often in a square block shape.

Aleppo soap

Natural soap

A natural Syrian soap from Aleppo made by hand following recipes handed down for thousands of years. In addition to olive oil, which is in most natural soaps, Aleppo soap contains laurel oil.

Castile soap

This one comes from central Spain. The story goes that the Crusaders brought the Aleppo soap to Europe in the 11th century. As laurel oil was unavailable in Europe it was replaced by olive oil, and in the case of Castile soap also at times by hemp oil. Castile soap is available as a hard soap and as a liquid soap.

Marseille soap

This soap from the South of France is similar to Castile soap, but it is a potassium soap. Seawater from the Mediterranean is used in the manufacturing process of Marseille soap, along with alkaline ash from sea plants and the typical French lavender.

Sulfur soap

Sulfur has a great antibacterial effect. The soap is recommended for people with oily or acne-prone skin. Since sulfur also dries out the skin, this soap is not suitable for everyone.

Peloid soap

The addition of peat (a specific type of peat with therapeutic properties) is characteristic of peloid soap. This soap is used, for example, in baths and spas.

Birch tar soap

It is a natural soap with an intense and rather unpleasant odour, which is often advised in the treatment of diseases like mycosis, psoriasis, alopecia, and acne. The dark, oily tar oil is extracted from the bark of trees such as pine, birch, or beech.

Soap allergies can be prevented

Natural soaps will cure and prevent a lot of allergies. Although there is always a possibility one of the substances won’t suit your skin. So it’s best to first try a small part of your body like your hands and forearms.

  1. I don’t have any problems with allergies, but my girlfriend does. She get’s allergy from most of the products, so we only stick to the natural ones. I came to read this article hoping to find some natural types of soaps which we don’t use yet. Thanks to your article, I now have a better idea.

    Which of the mentioned natural soaps have the best smell? If you could tell me that, I’d be very pleased. Thanks!

    • Hi Petar, I am so pleased that my article was of help. Great to hear that.

      Most of these soaps have a quite neutral smell. I must add that my nose is not very good, so a soap really must smell fierce for me to be able to smell it. But still, I can say that most soaps are neutral because of their substances. I use essential oils myself and add more drops than usual, so that I can smell it. 🙂 For me, that’s a good solution.

      If you go to an ecological shop they will probably have natural soap, like Marseille or Castile, as well as mixtures of natural soap with either oils or other ingredients to make them smell. Just be aware that those are not mixtures with palm oil or copra oil because those are not the best quality.

  2. Many years ago while vacationing in Spain, I developed an anaphylactic shock to the soap which was used to wash the sheets in the hotel we stayed at. Not knowing that I was allergic to soap, I even took my showers with the soap that was provided. I still remember the luscious black soap I just loved. On the third day I developed a rash which I treated myself with some antihistamine that was in our travel medicine container. On the fourth day the rash went wild. I had big blotches up to two inches long traveling up and down my body. Then my face swelled as well as my throat. I was not able to swallow any longer. By that time my husband had called the concierge who in turn had called a doctor.

    • That sounds like an awful experience, Ronnie, phew. I hope you are fully recovered. It’s strange you had it only in that hotel. Have you discovered which brand was the culprit?
      Take care and thanks for your reaction!
