In the Philippines, Kojic Soap is at rage in the market. Kojic Soap is known to have whitening abilities in an instant. Here's how to make one:
Glycerin Soap Base (Melt & Pour)
Orange Soap Colorant
2g Kojic Acid
2g distilled water
1kg MP base
8-10 drops of Papaya FO
0.5g of TD
5-10 drops of Orange colorant
1. Dissolve Kojic Acid in distilled water.
2. Melt base.
3. Let the base cool a little.
4. Add kojic solution to melted base.
6. Add TD, FO, then colorant.
Kojic Acid tends to oxidize. Always keep the soap in room temperature. Allow moisture to lock in the soap therefore refusing to allow humidity on it.
Kojic Acid tends to give orange-brown discolorations on the edges of the soap that's why soap companies that offer Kojic color them with an everlasting orange hue. But don't worry, it's just an aesthetic problem and the kojic power is still there. Well, now I know why. A tip to avoid having that discoloration (that your buyers wouldn't want) is to choose soap colors that would hide this discoloration. Example: ORANGE, brown or black.
There is another type of kojic that sells in the market. It's called: Kojic Dipalmitate. Its much more expensive than Kojic Acid but it does not give that awful brown discoloration. It is oil soluble and blends easily and perfectly. But yeah, my pocket doesn't blend easily with it's price.
In the picture, I made an activated Charcoal Kojic Soap and it is one of my bestest sellers!
