If you glance at the ingredient label of your favourite shampoo, it’s likely that you’ll find at least one alcohol-based item without straining your eyes. They are nigh on ubiquitous, even in ‘natural’ shampoos. There are tens (if not hundreds) of thousands of web searches every month looking for “alcohol free shampoos”.  Unfortunately for them, there are two main types of alcohol found in shampoos.  One you want to avoid and one you want to use.

Curious?

In this article we’ll explore the purpose and drawbacks of each type, as well as the alternatives if you want to avoid alcohols altogether.

Why are alcohols added to shampoo?

Alcohols are primarily used in shampoos as non-ionic emulsifiers, essential for keeping the ingredients mixed together in a cream or lotion [1]. Without an emulsifier, the ingredients would separate based on their solubility in water or oil, which would leave a highly undesirable product, similar in texture to curdled milk.

Note: the functionality of an –alcohol group can be used to modify the solubility of other ingredients. An example of this would be the secondary alcohol sulfates, which act primarily as surfactants (e.g. sodium sec‐lauryl sulfate) [2]. In this review, we’ll focus on the alcohols used as emulsifiers.

Which alcohols are found in shampoo?

There are two main types of alcohol found in shampoos: ‘short chain’ and longer chain ‘fatty’ alcohols.

Short chain alcohols are commonly found in products that need to evaporate quickly, such as perfumes and hairsprays. They aren’t overly common in shampoos, primarily because they are extremely water soluble, and so rapidly draw moisture from your hair [3]. Examples include:

  • ethanol
  • propanol
  • SD alcohol 40
  • isopropyl alcohol

Fatty alcohols are more commonly found in shampoos, as they have a less severe drying effect – and can conversely help to retain moisture [4]. Fatty alcohols are found naturally in some plants, such as coconuts, but this doesn’t necessarily mean that those found in your shampoo are ‘natural’. It’s more common for them to be manufactured synthetically on an industrial scale [5]. Fatty alcohols are easy to identify on ingredient labels, as they all have similar names:

  • cetyl alcohol
  • cetearyl alcohol
  • stearyl alcohol
  • myristyl alcohol.

The alcohols found in shampoos can be neatly summarised, by saying that:

  • short chain alcohols will draw moisture out of your hair
  • fatty alcohols are moisturising

Of course there’s an exception. In this case, ‘benzyl alcohol’ is a fatty alcohol but is extremely irritating to the scalp. It’s actually Benzyl alcohol is an incredibly popular ingredient that manufacturers love, but it will normally be one of the last ingredients as it’s used as a preservative in low concentrations.  If it’s any higher on the ingredient list, then you might want to consider avoiding the product altogether! [6].

What are the drawbacks?

Short chain alcohols have a number of downsides, but this is one of the reasons they aren’t routinely added to shampoos. They can be irritating, leading to contact dermatitis, and are known to remove the moisture from hair with repeated use [7]. If you find a shampoo with short chain alcohols high on the ingredient list, then they should probably be avoided.

Fatty alcohols have generally less negative publicity, but they can still cause irritation with repeated use. Cetearyl alcohol is a known allergen, which can present as severe contact dermatitis of unidentified cause (although this is more likely with cetearyl alcohol creams and bandages) [8]. Alarmingly, many fatty alcohols are derived directly from palm oil, which is linked with deforestation, habitat degradation, climate change, and abuse of native populations [9].

What are the alternatives?

So fatty alcohols are the ‘good’ alcohols, but are still derived from palm oil, which has a devastating impact on the environment and local communities – is there an alternative? Firstly, you can find ‘certified sustainable’ products that only use sustainable palm oil derived fatty alcohols, but you will need to research the awarding organisation to make sure it’s credible. There are also several alternatives to fatty alcohol emulsifiers:

1. Lecithin

Lecithin is a mixture of fats found in plant material, and acts as an effective emulsifier. The composition differs depending on the source, for example: soybean, rapeseed, or sunflowers. Like many ‘natural’ emulsifiers, the source can sound good, but the industrial process used to extract the material is not. In this case, non-polar solvents such as hexane and benzene are used to recover lecithin from plant material [10].

2. Emulsifying Wax

You’ll see this used by a lot of smaller manufacturers or hoe crafters of shampoos.   That’s because its incredibly easy to get hold of and easy to use too.

3. Xanthan Gum

One of my personal favorites, this fermented ingredient is actually a naturally forming bacteria.  You can produce it from whey – the leftovers from cheese.  I wish this stuff was more widely used!

4. Non-chemical emulsification

It’s possible to avoid chemical emulsifiers entirely by applying enough heat and mechanical energy. This is the gold standard in emusifying a shampoo, but is isn’t industry standard because it’s expensive.  The emulsified product is likely to separate over time (vastly reducing shelf lives) [11]. Anyone that has ever bought expensive peanut butter knows that all you have to do to restore the emulsion is stir or shake the product – but very few shampoos ask you to use this technique.  I wish they would personally.  Wouldn’t you rather shake your bottle than have emulsifying chemicals added to save you the hassle?

Pharmaceutical Specialities Free & Clear Shampoo

Designed to treat Seborrheic Dermatitis, Dry Scalp and Psoriasis

Pharmaceutical Specialties formed in 1974 to “start a company to make better products than were commercially available for people with sensitive skin”. And boy, have they achieved it with this Free and Clear shampoo.

What is perhaps surprising on a website dedicated to dandruff treatments is that this isn’t a dandruff shampoo at all.

It’s rather a "a non-medicated, mild shampoo for sensitive skin and scalp.”

That said, we can’t use a medicated shampoo all the time, and this is my go to shampoo for those “between” washes.
