"lavender infused" or "dandelion infused" that means that the sunflower oil used in them was infused with the botanicals before making the bars! Kathleen Pimm - NJ I started making handmade soaps 5 years ago and have evolved into selling it at various markets. My formula has evolved and I stay with the one that makes the hardest bar of soap. Soap formulation is a science that I have embraced. Preplanning the design and colors are important steps to making a successful batch of soap. Preplanning skin safe fragrance amounts are also important to me. I enjoy using different additives such as African Black Soap, milks and salts.
