Madder root (Rubia tinctorum) is a traditional natural dye plant that we can use to create a range of pink to purple in cold process soap. This is my favorite method for producing a true Barbie pink, along with tips on how to grow and harvest madder root in your own garden.

This video provides a comprehensive guide to creating homemade pink soap using madder root. It covers everything from growing and harvesting the plant to the specific cold-process soap-making technique used to achieve a clean, vibrant color without speckles.
This is homemade madder root soap.
It's based on a very simple cold processed soap recipe that
normally would be a creamy white color.
But with the addition of madder root, it's pink.
And depending on the technique you use,
the quality of the plant material, and the quantity,
you can get soap that ranges from a pale pink
to true pink to almost purple.
I am going to show you how to make my favorite
madder root soap recipe. It's a technique that's very easy.
It will give you this exact color of
soap and it makes five to six bars
and best of all you can make it from the comfort of your kitchen.
Madder is a weedy looking plant that we grow not for its beauty
but for the incredible red color
it hides away in its roots.
It comes from the natural compound alizarin and Europeans have
used it for hundreds if not thousands of years for dyeing wool,
fabric and other textiles.
Matter is an ingredient that soap makers tend to buy
and you can get it as dried root pieces
or as a powder so a root powder but you can
also grow it yourself and that's what I've been doing
in this birdie's bed here at the side of the house.
It grows in temperate regions so think
Europe, North America.
I think technically zones five to nine if you're using the U.S. system
but it loves a sunny place that is free draining
and it likes to grow undisturbed for several
years. It also does need quite a bit of moisture especially
when it's in its early stages but if
you give it that just forget about it
and then you have your own supply of homegrown organic
matter that you can use to dye wool
and fabrics and to use to make handmade soap.
You harvest the roots in late autumn once
the plants are three or more years old.
At that point the aerial parts might have died
back telling you it's time to dig the roots.
First cut the stems close to the crown
and then lift the roots as gently as you can.
It can be challenging though.
Then wash the roots with water and remove all the soil you can.
Chop it into small pieces and then dry it out completely.
It can take several weeks if you
leave them at a dry ventilated place out of direct sunlight.
In soap making we tend to use
dried matter root rather than fresh for a couple of reasons.
The first is pretty obvious,
we tend to buy it most of us
and it preserves it for long-term shelf storage.
The other thing is that when you dry
the roots it concentrates that natural compound called
alizarin that creates the natural pink color, the pink to red color.
And so you do need to dry the madder root
if you want the best effects for your handmade soap.
And as far as starting off with something purchased,
these are both purchased from a UK company, a dye stuff company.
You can use so many different techniques to make matter root soap.
One of the easiest is just adding
the powder directly to your soap batter.
But you can use both of these,
the roots or the powder, to infuse into oil
and then use the oil in soap making.
You can add it to the lye solution.
You can also use the powder to create pencil lines in your soap.
I'm going to show you the technique that works the best for me.
It doesn't leave any speckles in the soap.
It creates a nice...
Clean pink color and it is something that I use regularly
because one of my
soaps that I sell is made with madder root. So let's get to it.
Before we start making a soap it's safety first.
I go over soap making safety in depth in the
natural soap making for beginners course
but basically you need to wear eye and hand protection
and work in a way that protects yourself and other people
and animals from coming into contact with
anything caustic. You should
also measure all of your ingredients into separate containers
As shown on the screen.
We'll begin by making, and then cooling down, a matter infusion.
Pour the distilled water into a small saucepan
and heat it until it's at least scalding hot.
There will be some water evaporation during this stage,
so once the water is very hot,
measure 113 grams back into the heatproof jug.
Add the matter powder into the water
and make sure that it's well mixed.
Allow this infusion to cool
to room temperature. It takes about an hour.
Next, strain this infusion through a sieve lined with a cheesecloth.
This will catch the matter pieces
and stop them from getting into your soap.
It's an aesthetic step and optional.
If you wanted, you could have the matter pieces in your soap.
In a well-ventilated place,
pour the lye into the madder infusion and stir well.
Don't breathe in the steam that rises from the jug
and then allow the solution to cool down to 100 to 110 Fahrenheit.
That's 38 to 43 Celsius.
While it's cooling, melt the pan of solid oils on low heat.
Stir and break the oils apart as they melt
to help speed things along and do not leave the pan.
It melts quicker than you would think.
When the oils are almost completely melted,
take the pan off the heat
and allow the final pieces to melt.
Stir the jug of liquid oils
and gently pour it into the pan.
Stir all the oils together and take a temperature reading.
You want to cool these oils to 100 to 110 Fahrenheit,
38 to 43 Celsius.
When both the pan of oils and lye solution
are within this temperature window,
Gently pour the lye solution into the oils.
Stir well, then carefully place an immersion blender
into the solution.
I put mine in at an angle and burp it
to get as much air out of the head as possible.
Air can cause bubbles, froth, and splattering.
You want to then alternate using the immersion blender
as a spoon and stirring and holding it in one place
and pulsing a few times on the low setting.
When the immersion blender is moving ensure
that it's not on otherwise it can cause splatters.
Keep stirring and pulsing until
the soap mixture begins to thicken ever so slightly
then put the immersion blender down
and swap back to hand stirring with a spatula.
Stir until you see the faintest sign
of trace on the surface of the soap.
That's when you drizzle a little bit on top
and you see the faintest little trail of soap
left on the surface. At this point you can stir
in the essential oil if you're using it
and mix it in very well. Pour the soap batter into your mold of choice.
A loaf mold is better for encouraging gel
and showing off the pink color though.
Then take measures to help the soap reach gel phase.
You could wrap the soap with a thick towel taking care
not to get it into the soap.
What I tend to do though is put the soap
in an oven preheated to 170 Fahrenheit
which is 75 Celsius and then turn the oven off.
The warmth will push the soap into gel and enhance its color.
Leave the soap in the mold for two days before popping it out
and cutting it into bars and just look at that stunning pink color.
Once you've made your madder root soap and you've cut it into bars,
you need to cure it before you use it.
We've used a lot of water in the recipe
and that water needs to evaporate out.
That's one of the main purposes of curing.
Now technically the soap is safe to handle
and safe to use after 48 hours, but if you do use it,
it can disintegrate, the quality of the soap won't be great,
the lather won't be great,
so it's just better to wait.
And to cure it all you need to do is put down some greaseproof paper
in some place that is out of direct sunlight,
nice and airy, space out your bars and just leave them
there. Forget about them for a month and that water will reduce,
the soap will become more gentle,
The lather will be incredible.
And four weeks later, you can use the soap.
And I would recommend keeping it stored in the same kind of place,
so nice and airy, until you do use it.
And that's how you make madder root soap.
It's really easy. It is quite fun if you're a gardener
and you like to grow
plants to use in interesting recipes and interesting crafts.
