Cupuacu body lotion for dry skin

May 3, 2022 | Body care, Formulations

I am continueing my formulations with cupuacu butter as it is wondeful for dry skin. This time we are making body lotion for dry skin with several humectants.

Formulating a cupuacu body lotion

1. Star ingredient – cupuacu butter

The main ingredient here is cupuacu butter which has an impressive ability to hold water molecules. It is a rather hard butter that doesn‘t leave a film on the skin and has a satiny, velvety dry feeling after application. Which is why I thought it would be great to make a body lotion for dry skin.

Cupuacu butter has a strong scent that is similar to chocolate, but it is deeper and long lasting. It also has phytosterols that improve skin‘s barrier function and polyphenols that are powerful antioxidants.


I have used a high amount of this butter which also affected the viscosity of the final lotion. As the butter has quite a lot of fatty acids it made the lotion thicker.

If you like cupuacu butter – here some other recipes that you can try:

2. humectants

I have used 3 different humectants – sodium lactate, erythritol and 1,3-propanediol. Sodium lactate has on of the highest ability to hold water after hyaluronic acid. It can also work as a weak buffer to prevent changes in skin pH.

Erythritol is a sugar alcohol that is used in dental care as well as a moisturizing active in skincare. It also has some hair detangling properties.


1,3-propanediol is an ingredient primarily used as a solvent, humectant and emollient. It is a safe ingredient that retains moisture and decreases viscosity. As it has several benefits to the skin, it can be found in almost any type of product. However, if you don‘t have it, use glycerin instead.

3. formula and recipe

Phase A

59.4 g | 59.4 % Distilled water

8 g | 8 % 1,3-pranediol

2 g | 2 % Sodium lactate

3 g | 3% Erythritol

Phase B

5 g | 5 % Glyceryl stearate SE

15 g | 15 % Cupuacu butter

5 g | 5 % Rice bran oil

2 g | 2 % Behenyl alcohol

Phase C

0.6 g | 0.6 % Cosgard (preservative)

This makes 100 g of the product.



  1.  Weigh all ingredients from phase A and B into different beakers. Weigh beaker with A phase ingredients and write it down.
  2. Place the beakers into a water bath and heat them until they reach 75-80°C / 167-176°F.
  3. Weigh beaker with A phase ingredients again and add hot distilled water to account for the missing water (that has evaporated during heating).
  4. Combine both phases in one beaker and mix with a blender. It is necessary to use a blender here, as glyceryl stearate SE emulsifier needs high shear to combine oil and water phases.
  5. Blend for the mixture for a minute or two, then leave it to cool a bit and blend once again. Repeat this several times.
  6. When the lotion reaches 40°C / 104°F add the preservative and blend again.
  7. Check the pH – it should be 6.0-7.0 range for the preservative and emulsifier to work.
  8. Leave it to cool.


  • You can use glycerin instead of 1,3-propanediol.
  • Provitamin B5 or water can be used instead of sodium lactate.
  • You can use water instead of erythritol.
  • Another emulsifier can be used instead of glyceryl stearate SE.
  • Cetyl, cetearyl alcohols can be used instead of behenyl alcohol.
  • You can use a different broad spectrum preservative.



6. application and perception

The body lotion for dry skin spreads easily, leaves a fresh feeling. The scent from cupuacu butter stays for a bit, then disappears.

After a week or so the texture shifts to more of a rich thick cream. This happens because of high amount of cupuacu butter, that has lots of stearic acid. And stearic acid is a very good thickener that gives this creamy feeling.
