Colours - pigments or dyes?

Monday, 2 January 2017 11:35

We sell both Water Based Dyes and Liquid Pigments and we are often asked which is the best to use.

Water based dyes are ideal for both melt and pour soap bases and bath bombs.  They are water soluble and work well in both clear and opaque bases.

However, they will bleed.  By this we mean if two different coloured soap bases are next to each other in stripes or layers for example, the colours will merge and mix over time.  If you are looking to make soap in layers then do consider the use of pigments instead.

We recommend that only dyes are used in bath products (salts, bombs) as this will avoid any staining of the bath.

Pigments are also suitable for melt and pour soap bases but are really only suitable for opaque bases.  If you use a pigment in a clear base the result will be hazy and give a grainy appearance.  Pigments are supplied in liquid form and so you should shake the bottle before use to ensure all the colour has not sunk to the bottom.  We do not recommend their use in bath products such as salts or bombs because the tiny bits of colour will stick in any scratches in the bath and possibly stain it.

Both are supplied in a concentrated form and can be further diluted with deionised water if required.   You can always add more colour but you cannot take it away!

Using colours in salts can also give varying results in that the colour may not be as expected.  Please do test first before launching any large scale manufacturing to ensure you will get the required end result.  Test test test and test again is always the best advice.

Using Titanium Dioxide

Monday, 2 January 2017 11:36

Titanium Dioxide is the ingredient that turns a clear soap base into an opaque soap base.

It comes in powder form with the look and texture of flour.  It is also known by the Colour Index number of CI 77891or Pigment White 6.

So how do you add it to melt and pour soap?  Firstly do not add it directly as a powder - it will clump and lump and not disperse in to the soap base well.

It is best to mix it with either water or vegetable glycerine to make a paste before adding to the melted soap.

Add up to 1% of the melted soap base to make it white.  Be careful not to add too much as it will sink to the bottom when the soap is set.

If you are using this in cold process soap making, then you can also disperse it into your base oils.

Fragrance Oils or Essential Oils?

Monday, 2 January 2017 11:36

What's the Difference?
 

Fragrance Oils are manufactured oils.  They can contain essential oils and many fragrance oils such as Orange and Lemon do.  However, they will also contain synthetic ingredients to produce delicious fragrances such as Christmas Spice or Seaweed and Juniper or even Chocolate Orange.  They are man made in a factory and while they may contain some natural ingredients they cannot boast a claim as being a "natural product."

Essential oils are pure and natural oils that are usually obtained by distillation from the originating plant.  Many are available, all with different prices and all with different properties.

Both our fragrance and essential oils are concentrated and so should not be applied undiluted directly to the skin.

As to which oil to use - it is all a matter of personal preference.
 

Fragrance Oils will produce a huge range of different scents.  Whereas Essential Oils may have other therapeutic benefits.

Remember that if you are using Essential Oils to check that they are suitable for your application.  Some oils for example have a limit to their usage in cosmetics.
