Goat milk bath: what it is and how to run one
A goat milk bath is a warm bath with goat's milk, usually as a powder, dissolved into the water. It turns the water soft and pale and gives the bath a gentle, creamy feel. Keep the water warm rather than hot, soak for 15 to 20 minutes, and skip it altogether if you are allergic to milk.
Quick answer
- What it is: a warm bath with goat's milk or goat milk powder dissolved in it.
- What's in goat's milk: fats, proteins, lactose (milk sugar) and minerals, in roughly the same proportions as cow's milk.
- How to run one: dissolve the powder in warm water first, add it to a warm bath and soak for 15 to 20 minutes.
- What it's for: the look and feel of the water, and the ritual. It is a cosmetic, not a medicine.
- Who should skip it: anyone with a milk allergy.
What is a goat milk bath?
A goat milk bath is a bath with goat's milk added to the water. The easiest form is goat milk powder, which is goat's milk dried to a fine powder: it keeps in the cupboard, measures easily and dissolves into warm water without the waste of pouring in litres of fresh milk.
You'll also find goat milk in soaps, creams and bath products. Milk-based ingredients are widely used across the cosmetics industry.
What is in goat's milk?
Goat's milk carries fats, proteins, lactose and minerals in water. The fats sit in tiny emulsified droplets and the proteins in fine clusters, spread evenly through the liquid. By weight, goat's milk is roughly 4% fat, 3% protein and 4% lactose, with under 1% minerals.
Those are the same building blocks as cow's milk, in broadly similar amounts. Goat's milk is still dairy, so it isn't a choice for anyone avoiding milk.
What does a goat milk bath do for your skin?
A goat milk bath changes how the water looks and feels. The water turns pale and soft, and many people find skin feels comfortable and smooth afterwards rather than squeaky-clean. That is the whole of it: a goat milk bath is about the feel of the water and the pleasure of the soak.
It is a cosmetic, not a medicine. If you have a skin condition, speak to your GP or pharmacist before trying something new.
Did Cleopatra really bathe in milk?
There is no ancient source for Cleopatra's milk bath. One historian traces the story to writers of the 1700s, who moved it from a lesser-known Roman empress onto Cleopatra; films of the 1930s and 1960s then made it famous.
The milk bath that ancient writers did record belonged to Poppaea Sabina, wife of the Roman emperor Nero. Pliny the Elder wrote that she kept five hundred donkeys for their milk and bathed in it. So the most famous milk bath in history was donkey's milk, and its bather was Roman rather than Egyptian.
How do you run a goat milk bath?
To run a goat milk bath, dissolve the powder in a jug of warm water, add it to a warm bath, and soak for 15 to 20 minutes.
- Run the bath warm, not hot. Close to body temperature is right; it should feel pleasantly warm on your elbow or wrist.
- Dissolve the powder first. Whisk it into a jug of warm water so it doesn't clump, then pour it in as the bath finishes filling. Follow the amount on the pack.
- Swirl the water with your hand so the milk spreads evenly.
- Soak for 15 to 20 minutes.
- Rinse with clean water if you like, pat dry, and moisturise while your skin is still slightly damp.
- Rinse the bath afterwards so no milk is left on the surface.
For more on timing and temperature, see how long to soak in the bath.
How often can you have a goat milk bath?
Once or twice a week suits most people, as a ritual rather than a routine. If your skin feels dry or reacts in any way, take a break.
Who should avoid a goat milk bath?
Anyone with a milk allergy should avoid a goat milk bath: goat's milk is dairy, just as cow's milk is. If you have sensitive skin, patch-test any new bath product on a small area first. Check with your doctor or midwife if you are pregnant or have a skin condition.
Goat milk vs oat milk in the bath
Goat milk and oat milk give the water a similar pale, creamy look, but they are entirely different ingredients:
- Goat milk is dairy: milk from goats, usually dried to a powder.
- Oat milk powder and colloidal oat come from oats, a plant, so contain no dairy.
For more on oat, see our guide to the oat milk bath.
Goat milk in SLATE
SLATE's MILK block is made with goat milk powder. It makes up 5% of each pressed block, about 1.1 g in a 22 g block, alongside the base every block shares: Epsom salt (10%), kaolin clay (3%) and the bicarbonate and citric acid that make it fizz as it dissolves.
To be clear about amounts: a single MILK block adds a little goat's milk, not a full milk bath. Twelve MILK blocks hold about 13 g of goat milk powder; a full Grid™ of 27 holds about 30 g. The more MILK blocks you add, the more of a milk soak your bath becomes. Pair them with a scent block for fragrance. The System explains how texture and scent blocks combine.
