vegetable oils

Our soaps start with vegetable oils good enough to eat.

The excellence of our soaps comes from the integrity of our basic ingredients. We use only food-grade oils to nourish your skin. By blending four base oils—olive, rice bran, palm kernel, and soy—we handcraft a bar of soap that's moisturizing, long-lasting, and luxuriously lathering.

This type of soap making is alternately called “cold process soap,” “lye soap,” or since we use olive and all vegetable oils, “Castile soap.”

To convert the oils into soap, we add lye, sodium hydroxide. Don’t fear; there is no lye left in finished bars. The fatty acids and the lye neutralize each other and form a salt called soap. Basic chemistry.

During the process, glycerin is formed from triglycerides. The glycerin is a natural by-product of cold process soap making. It composes about 8% of each bar. Glycerin feels silky smooth on your skin. It’s a humectant, gathering moisture from the air.

You can pronounce the ingredients in all our products.

We use no synthetic preservatives, no petroleum products, no triclosan, no phthalates, no formaldehyde, no artificial colorants and dyes… The list of what we don’t include is frightening.

almond oil

We add to our basic soap recipe one or more oils and/or butters to moisturize your skin. This is called “superfatting.”

We also offer oils and butters to use as moisturizers. You'll find them more effective than conventional lotions.

essential oils

The aromas in Herbaria soaps and products come from essential oils derived from plants. We are careful to select oils from sustainable plants, avoiding those from endangered species such as sandalwood or rosewood. Read more about the benefits of essential oils


The primary texture we add to our soaps is oatmeal. It is unsurpassed for exfoliating and soothing your skin. As for colorants, we choose herbs and clays, no synthetic colorants.
