[Post updated: 18.06.24]<\/h6>\n

In this post, we are going to show you four natural solubilisers. We’ll take a look at how they work and what you, the formulator, need to focus on when working with them.<\/p>\n

Our list of solubilisers covers some currently available on the market that can be used in natural skincare.<\/p>\n

But first, let\u2019s recap on the group of cosmetic ingredients solubilisers belong to and the role they play in our natural cosmetic formulations.<\/p>\n

What are solubilisers?<\/h2>\n

Solubilisers belong to the surfactant group alongside emulsifiers.<\/p>\n

While they are classified in the same cosmetic ingredient group, there are differences between solubilisers and emulsifiers.<\/p>\n

We discuss these differences in our post: Solubiliser vs emulsifier: which one do you need in your formulations?<\/a><\/p>\n

At a fundamental level, solubilisers are completely soluble in water. They are effective in dispersing small concentrations of oils in aqueous mediums, usually less than 2%, depending on the ingredient.<\/p>\n

Typically, these oil-soluble compounds have a small molecular size, as is the case with essential oils, fragrances, and some oil-soluble preservatives.<\/p>\n

It is important to note that solubilisers are usually less effective at dispersing vegetable oils.<\/p>\n

When dispersed, the minimal oil phase is distributed in small particles, resulting in a clear solution.<\/p>\n

We cover more on the science of surfactants in our post on how to make a natural mint and rosemary shampoo<\/a>.<\/p>\n

When to use solubilisers<\/h2>\n

If you intend to incorporate a small amount of oil, such as an essential oil, into a water-based product, using a solubiliser is worth considering.<\/p>\n

A classic example of this is a facial toner with added essential oils. Without a solubiliser, the oil droplets would remain on the water\u2019s surface, forming a concentrated pool.<\/p>\n

Not only does this look aesthetically unpleasing, but it also poses a risk to the consumer. As the essential oil remains undispersed in concentrated drops, it is possible to apply excessive amounts, which could cause skin reactions.<\/p>\n

To create a clear and visually appealing aqueous base, the essential oil should be mixed with a solubiliser before adding it to the water medium. This process results in a crystal-clear solution without the oil pool on the surface.<\/p>\n

Some solubilisers create cloudy solutions, and as long as the oil doesn\u2019t separate, it should not cause any risks. Customers can use the product without worrying about using concentrated amounts of essential oils topically.<\/p>\n

It’s important to note that solubilisers are typically not used to incorporate carrier oils into a water base. Although, some solubilisers may be suitable for this purpose.<\/p>\n

Also, some preservatives have oil-soluble components that should be solubilised before being added to a water-based product. This is to ensure proper dispersion and safety.<\/p>\n

How to use a natural solubiliser<\/h2>\n

You always need to follow the supplier\u2019s recommendation regarding usage amount.<\/p>\n

The amount of solubiliser needed to disperse oils will also depend on the chosen oil.<\/p>\n

Here, we are working with blue chamomile essential oil and testing various ratios. You will always need to follow these steps:<\/p>\n

    \n
  1. Blend the essential oil with the solubiliser until you get a homogenous mix.<\/li>\n
  2. Try to avoid creating too much foam.<\/li>\n
  3. Add this mix to the aqueous base and blend well. (You can also add the water to the blend.)<\/li>\n<\/ol>\n\n

    Testing our Natural Solubilisers<\/h2>\n

    Now let’s see how they work in practice.<\/p>\n

    In this first picture, we added blue chamomile essential oil to water without any solubiliser. As you can see, they don\u2019t mix, and the oil floats on the water\u2019s surface.
    \n\"natural<\/p>\n

    Next, we added the essential oil and a solubiliser to a watch glass. We will mix them before adding them to the water base.
    \n\"how<\/p>\n

    Below, you can see a comparison between the essential oil added without a solubiliser and then solubilised at different ratios. In the middle beaker, we got a cloudy solution, and by adding more solubiliser, we got a clear solution in the third one.
    \n\"<\/p>\n

    Remember, not all essential oils will need the same ratios of solubiliser, so keep experimenting and share your findings in the comments below.<\/p>\n
