Thank you for visiting! All soap is handmade in small-batches using the cold process method, with natural colorants and essential oils.

Delta Tule is a woman-owned company (with a lot of family support) in sunny California next to the San Joaquin River. All soap & body care products are carefully handmade by me (Leah) in small batches. I am also a mom and graphic artist and spent most of the summers of my childhood on the California Delta. It is still one of my favorite places to be, and the inspiration for this brand.

I make soap using the cold-process method, where I have full control of all the ingredients. Some of my favorites are essential oils, botanicals, and natural colorants such as cosmetic-grade clays, activated charcoal, and herbal infusions. I never use sodium lauryl sulfate, parabens, or phthalates, and only test products on willing humans.

I love the benefits of using natural soap plus helping to reduce single-use plastics. I started making soap for a variety of reasons. I was (and still am) mesmerized by the balance between science and art in the soap making process. After months of research, I finally made my first batch and was immediately hooked.

Why choose handmade soap you say?

A true soap retains its natural glycerin produced during saponification, the process of turning oils into soap. Glycerin is a natural moisturizer and cleanser that increases lather and produces a milder soap. Saponification occurs by mixing fats (natural oils) and sodium hydroxide (lye) at precise ratios and temperatures.

In many commercial soaps, the valuable glycerin is extracted, sold, and replaced with cheaper synthetic alternatives. These may be harsher and irritating to some skin types.

I also suffer from a range of seasonal allergies and skin sensitivities. Many ingredients in store-bought products are always a risk for an attack of itchy and irritated skin. Using handmade soap has helped my skin in so many ways. I love being able to share the benefits with others. The fact that it's a practical product that also helps reduce single-use plastics is also a win!

So many reasons for me to love everything about soap and "momtreprenuership." Thank you for supporting me and my family in our small business adventure. We hope you love our soap as much as we do!
