Frequently Asked Questions (FAQs)

1. Does castor oil make a hard bar of soap?

Castor alone makes a mushy not hard or brittle bar, though if used in higher percentages, it can make a nice shampoo bar. It'll never reach the fluffy lather of a coconut oil shampoo bar, though. Castor oil added to a soap recipe results in a stable lather that is low, dense, and creamy.

2. What does castor oil do in a bar of soap?

It increases lather in the soap which a imparts rich and creamy texture leaving a very bubbly feel. Castor oil is a humectant, i.e., it keeps our skin aptly moisturized. Around 10% of castor oil in the soap recipe will make wonders. The fatty-acid make-up of castor oil is unique.

3. Is castor oil soap good for skin?

There are innumerable Castor oil soap benefits like it is rich in ricinoleic acid which helps in fighting the skin bacteria that cause acne. It easily penetrates the skin layers and makes the skin smooth, supple to vitalize it naturally.

4. What kind of soap is used to make castor oil?

Castor oil is a natural thick, clear oil that helps produce a rich, creamy lather in soap. Castor oil is a humectant which attracts moisture to your skin. We suggest using 5% - 8% castor oil in cold process/hot process soap recipes.
