Question

Pink colour in soap is produced by using
Options​

Answer 1

What colorant you use plays a big role in how vibrant the soap will be. For instance, micas create gorgeous color in melt and pour soap, but some can morph or fade in cold process soap. Before choosing the colorant for your recipe, make sure to check how it performs. The descriptions on Bramble Berry have information on how the color performs, and some also have pictures of the colors in a finished bar of soap. The Talk It Out Tuesday: Colorants post also has helpful information, including how to use each color in your recipe.

Answer 2

Answer:

Phenolphthalein.

Explanation:

In an acidic solution, phenolphthalein is colourless, but in a basic solution, it turns pink.

Soap is a very basic product.  Hence, Phenolphthalein has a pink colour in soap solutions.
