Our Process
Small Batch. Cold Process. No Shortcuts.
Since 1973, the Bogue family has hand-crafted cold-process goat milk soap in Ojai, California — from Helen, to Susan, to her son Adam. This is the process, step by step, exactly as we do it today.
This Is Not Hobby Soap.
Every bar of Bogue Milk Soap is still made the way Susan first learned it at Grandma Helen's all-handmade shop, Dos Manos, which Helen opened in 1973: small batch, real goat milk, and the traditional cold-process method — no shortcuts, no mass production. Three generations later, this is exactly how a bar goes from fresh milk, local botanicals, mineral clays and plant oils to a cured, hand-cut bar that already fits in your hand and is ready for your bathroom shelf — not an artificially colored slice of soap loaf.
Preparing the soap base
Cold-process soap only turns out as good as its ingredients. We start with raw goat milk, blended with distilled water and a touch of powdered goat milk. Fresh milk carries naturally occurring lactic acid — a gentle alpha hydroxy acid — along with a fat and protein structure that holds up through saponification without breaking down or scorching.
Some of that distilled water is frozen ahead of time, so the milk stays cold right up until it’s blended into the batch. Heat is the enemy of good goat milk soap: it can scorch the milk’s natural sugars and turn a creamy bar orange or brown before it’s even cured.
Each small batch uses about 250 oz of goat milk, plus another 650 oz from our 12+ organic plant oils and butters — so while we’re melting the solid oils, we’re cooling the liquid ones to keep every ingredient at the right temperature before they meet.
Mixing Oils, Butters & Lye
Each batch starts with a base of plant oils and butters. Where most soap — including a lot of what you'll find on store shelves — is built from just one to four oils, we blend at least twelve, sometimes more depending on the batch, with our Bespoke and Wellness lines adding one to three more on top of that. Every oil and butter is brought together with a lye (sodium hydroxide) solution.
This is the chemical reaction called saponification, and it's what actually turns oil into soap. Getting the ratio of oils to lye right — what's known as the “superfat” — is what determines whether a finished bar is gentle and moisturizing or overly harsh and drying.
Our plant oils, water, and goat milk are all organic — together that's about 900 of the 1,000 ounces in a finished batch, with the rest coming from the lye solution itself. And there's no artificial dye or fragrance anywhere in it: every bit of color and scent comes from botanicals and pure essential oils, never a synthetic fragrance oil.
Blending in the Goat Milk
Because milk can scorch or curdle if it gets too hot during saponification, we blend the goat milk in carefully once the base mixture is ready, at a closely controlled temperature. This is the step that most separates a true goat milk soap from one that simply lists milk far down an ingredient list — for us, the milk is a core structural ingredient, not an additive stirred in at the end.
Adding Botanicals, Clays & Essential Oils
Once the base is blended, each formula gets its individual character. It starts with botanicals infused into olive oil — the first ingredient that begins to set one blend apart from another.

Pouring, Layering, Striping & Topping by Hand
Hand-Poured, Striped & Layered
Every batch is poured into molds by hand, not machine-dispensed. Blends with a striped or layered look are spooned in while the soap is still workable — which means no two bars are ever perfectly identical, a small trade-off we're happy to make for a genuinely handmade product.
Bespoke Exfoliating Tops
For special bespoke bars with an exfoliating top half, the aggregates are mixed in and poured on as a separate top layer. From there, infused herbs or scrubs are added on top of some bars as a finishing touch.
Why We Never Rush the Cure
This is the step that separates real cold-process soap from a soap that just looks handmade.
After unmolding and cutting, bars cure on open racks for roughly four to six weeks.
During curing, the saponification reaction finishes fully, excess water evaporates, and the bar becomes harder, milder, and longer-lasting.
A bar sold before it's cured would be softer, could irritate skin from residual lye, and would dissolve far faster in the shower.
We don't rush this step.
Cutting & Quality Checks
Cured logs are cut into individual bars that fit comfortably in your hand, using a rack and wire bread loaf slicer. Each batch is checked before it's approved for sale: consistent color and texture, no air pockets or soft spots, correct weight of over 5oz per bar, and confirmation that saponification finished properly. Bars that don't meet the standard don't go out under the Bogue name.

Why the Process Matters
None of this is about romanticizing “handmade” for its own sake. A properly cured, cold-process goat milk soap genuinely behaves differently on skin than a quickly manufactured bar: it retains more natural glycerin, it's milder because the lye has fully reacted and mellowed over weeks of curing, and the fresh goat milk's lactic acid and fat content are still intact rather than degraded by high heat. The unique plant oil and butter base, the mineral clays, and pure essential oils all lift this soap to another level. That's the difference our customers notice, and it's the same process — just refined through three generations of practical experience at the soap bench — that's been running in Ojai since 1973.

Frequently Asked Questions
How long does the soap actually take to cure?
Bars cure on open racks for roughly four to six weeks. During that time the saponification reaction finishes fully, excess water evaporates, and the bar becomes harder, milder, and longer-lasting.
Why not sell the soap right after it's cut?
A bar sold before it's cured would be softer, could irritate skin from residual lye, and would dissolve far faster in the shower. We don't rush this step — it's what separates real cold-process soap from a bar that just looks handmade.
What quality checks does each batch go through?
Every batch is checked before it's approved for sale: consistent color and texture, no air pockets or soft spots, correct weight of over 5oz per bar, and confirmation that saponification finished properly. Bars that don't meet the standard don't go out under the Bogue name.
Why does each bar look slightly different?
Every batch is poured into molds by hand, not machine-dispensed. Blends with a striped or layered look are spooned in while the soap is still workable, which means no two bars are ever perfectly identical — a small trade-off we're happy to make for a genuinely handmade product.
What goes into the soap besides goat milk?
Botanicals are infused into olive oil, then we add mineral clays for color and skin benefits, along with pure, steam-distilled essential oils — as many as 10 or more for some shave soap blends. We also decide what a bar won't contain: no synthetic fragrance oils, no artificial dyes, and no unnecessary fillers.
Is this really handmade, or mass-produced?
Every bar is still made the way Susan first learned it at Grandma Helen's all-handmade shop in 1973: small batch, real goat milk, and the traditional cold-process method — no shortcuts, no mass production. Three generations later, it's the same process, just refined through decades of practical experience at the soap bench.
