2 teaspoons sodium lactate, 2 teaspoons fizzy lemonade colorant, and 1.6 oz. pink grapefruit fragrance oil.

Batch Notes

I created the silicone duck mold by casting a toy rubber duck in liquid silicone. I lowered the amount of coconut oil in this recipe to make a less astringent soap for children.
