How we make cold process soap in Mapleton, Utah

Cold process bar soap is where Wild Bear Market started. Before the car fresheners, the room sprays, and the solid dish soap, there was a family in Mapleton, Utah, stirring pots of oil and lye and hauling trays of curing bars to craft fairs. Christina, the Wild, and Justin, the Bear, founded the company in 2019 with exactly one product line, and it is still the thing we are proudest to make by hand. You can read the whole beginning on our Our Story page, but this post is about the part most people never get to see: how a bar actually comes together.

The short version is that we make soap the slow, old-fashioned way, from a short list of plant oils and butters, in small batches we can watch over from start to finish. The clean, simple ingredients are usually what get someone to pick up their first bar. The scent is what brings them back. More on that at the end.

What cold process soap actually is

Every true bar of soap starts the same way, with oils and a lye solution. Cold process is the method where we combine those two at low temperature and let them do the work themselves, rather than cooking the batch with outside heat. When oils and lye meet, a reaction called saponification begins, and over the next several weeks it turns those raw ingredients into soap and natural glycerin.

That word, lye, makes some people nervous, so here is the honest version. Lye (sodium hydroxide) is the ingredient that makes soap soap. There is no such thing as a real bar of soap made without it. What matters is that saponification uses it up. In a properly made, properly cured bar, the lye is fully converted, and what is left in your hands is gentle, glycerin-rich soap. Being straight about that is more useful than pretending soap makes itself.

The ingredients we start with

A cold process bar is only as good as the oils that go into it, so that is where our attention goes first. We build our bars on plant-based oils and butters, the kind of short, readable list we would want on our own bathroom sink:

• Rich butters like shea and cocoa butter, which give a bar its conditioning, lotion-like feel.
• Coconut oil, which brings the lather and the cleansing.
• Softer oils like olive and other plant oils, which round out a mild, skin-friendly bar.

We scent our bars with phthalate-free fragrance and formulate them with no California Proposition 65 listed ingredients, because a lot of the people who buy handmade soap are exactly the kind who read the back of the package before anything touches their family. We would rather earn that trust than talk around it. What we leave out is part of the recipe too.

A small batch, start to finish

Here is roughly how a batch comes together in our Mapleton kitchen.

We measure everything by weight. Soap making is closer to baking than cooking. Every oil, the water, and the lye are weighed to the gram, because the ratio is what makes a bar safe and mild instead of harsh. This is the least glamorous step and the most important one.

We warm the oils and mix the lye solution. The butters and hard oils are melted gently and combined with the liquid oils. Separately, lye is dissolved into water. Both are brought to a friendly, similar temperature so they blend smoothly.

We bring the batch to trace. The oils and lye solution are combined and blended until the mixture thickens slightly to a pudding-like state soap makers call trace. That is the signal that saponification is underway and the batch is ready for the good part.

We add scent and character. At trace we fold in the fragrance and any natural touches for a given bar, whether that is a swirl of color, a dusting of botanicals, or the oats in an oatmeal bar. This is where a batch stops being chemistry and starts being a specific Wild Bear scent.

We pour, insulate, and wait. The soap goes into molds and rests for a day or so while the reaction finishes and the loaf firms up. Then we unmold and cut it into bars by hand, which is why no two bars are ever quite identical twins.

We cure for four to six weeks. This is the patience part. Fresh-cut bars are set on racks to cure for about a month or more. During the cure, extra water evaporates and the bar hardens, so it lasts longer in your shower and lathers better. There is no shortcut here, and we do not take one.

By the time a bar reaches you, it has been handled, checked, and waited on by actual people in a small Utah town. That is not a marketing line. It is just how small-batch cold process works.

Why we still do it the slow way

We could make more soap, faster, with different methods. We stick with cold process because it keeps the glycerin in the bar, lets us control every ingredient, and produces the kind of mild, long-lasting bar that started this whole company. Small batches also mean we can actually stand behind every one, which is why our bars come with our 100% Scent Satisfaction Guarantee. If a scent is not for you, we will make it right.

The part people fall for

Clean ingredients and an honest process are why someone tries their first bar. The scent is why they keep a stack of them in the linen closet.

That is the quiet magic of a cured bar of soap. Oat Milk & Honey is warm, creamy, and comforting, the bar people reach for when they want their shower to feel like a soft morning. Coastal Linen is bright and fresh, like clean laundry drying in sea air. Sugar Bear is all sugared citrus, and Garden Mint is a cool, green wake-up. The clean formula gets your attention. The scent, still on your skin a few minutes after you towel off, is what turns one bar into a standing order.

Frequently asked questions

What is cold process soap?

Cold process soap is soap made by combining plant oils and butters with a lye solution at low temperature and letting saponification turn them into soap and natural glycerin. It is the traditional, from-scratch method, and it is how we make every Wild Bear bar in Mapleton, Utah.

Is there lye in your bar soap?

Every real bar of soap is made with lye, because saponification is the reaction that creates soap in the first place. In a properly made and fully cured bar, the lye is completely converted, so what you wash with is gentle, glycerin-rich soap, not lye.

How long does cold process soap take to make?

The mixing and pouring happen in a single day, but the bars then cure on racks for about four to six weeks. Curing lets extra water evaporate so the bar gets harder, lasts longer, and lathers better. That wait is why we make in small batches and plan ahead.

What ingredients are in your soap?

We build our bars on plant-based oils and butters like shea butter, cocoa butter, coconut oil, and olive oil, scented with phthalate-free fragrance. Our soap is formulated with no California Proposition 65 listed ingredients.

Why choose handmade bar soap over a bottle of body wash?

A cold process bar keeps its natural glycerin, uses a short list of ingredients you can read, and skips the plastic bottle. For people who like knowing exactly what they are putting on their skin, and who enjoy a good scent, a handmade bar is an easy trade.
