How to Start a Soap Making Business
Handmade soap is a product people use every day, gift often and reorder when they love it. That makes a soap making business an appealing side hustle or small brand. But soap sits closer to the rules than many crafts, especially once you make skin claims. This guide covers the methods, the regulations in the US and UK, safe production, costing and how to win repeat customers.
Key takeaways
- Choose a method that fits your skills and space: melt and pour, cold process or hot process.
- In the US, true soap is regulated by the CPSC, but products with cosmetic claims fall under FDA rules. Your wording matters.
- In the UK, cosmetics need a Cosmetic Product Safety Report, a Responsible Person and notification on the government's SCPN portal before sale.
- Cost every bar fully, keep batch records and build repeat buyers with a small, reliable core range.
Mid-January is a good time to begin. Many people make healthier, simpler routines in the new year, and handmade soap fits that mood. If you make cold process soap, the long cure time also means bars you pour now could be ready for spring markets, Mother's Day gifting and wedding favor season.
A quick note: this article is general information, not legal, regulatory, tax or insurance advice. Cosmetic and product safety rules are detailed and change over time, so check the official guidance in each country where you sell, and speak to a qualified safety assessor, lawyer or accountant where relevant.
Choose your soap making method
Your method affects your equipment, your safety setup, your production time and how much creative control you have.
Melt and pour
You buy a premade soap base, melt it, add color and fragrance, and pour it into molds. There is no lye handling at your end, bars are ready quickly and it is beginner-friendly. The trade-off is less control over the base ingredients and a story that is harder to differentiate.
Cold process
You combine oils and butters with a lye solution and let the chemical reaction, called saponification, turn them into soap. You control every ingredient, which allows distinctive recipes and designs. Bars need to cure for several weeks before sale, and working with lye requires strict safety precautions.
Hot process
Similar ingredients to cold process, but you cook the soap to speed up saponification. Bars have a more rustic look and can be usable sooner, although many makers still let them cure for better hardness.
Pro tip
Many successful soap makers start with melt and pour to test designs, packaging and demand, then move to cold process once they know what sells. You do not have to master everything before your first market.
Understand the rules before you sell
This is the section most hobbyists skip, and the one that matters most for a real business. Set up the usual basics as well: a business structure, registration, any licenses and permits your location needs, insurance, pricing and an invoicing setup.
United States: soap or cosmetic?
In the US, true soap is regulated by the Consumer Product Safety Commission (CPSC). But if your product makes cosmetic claims, such as moisturizing, deodorizing or anti-aging, it falls under FDA rules for cosmetics, which bring their own labeling and safety requirements. Claims to treat or prevent conditions, such as acne or eczema, can push a product into drug territory, which is far more heavily regulated.
That means your product descriptions, labels and social media posts all matter. "Gentle bar with shea butter" reads very differently from "heals dry skin". Read the FDA's current guidance on soap and cosmetics, and keep your claims modest and accurate.
United Kingdom: cosmetic safety requirements
In the UK, soap sold for use on the skin is generally treated as a cosmetic. Before you sell, each product needs a Cosmetic Product Safety Report (CPSR), usually prepared with a qualified safety assessor; a Responsible Person who is accountable for compliance (often you, as the maker); and notification on the government's Submit Cosmetic Product Notifications (SCPN) portal. Labels must also meet cosmetic labeling rules. If you sell into the EU, separate EU requirements apply.
Common mistake
Tweaking a recipe after it has been assessed, for example swapping an oil or increasing the fragrance, and continuing to sell it under the old safety report. In the UK, a changed formula generally needs its safety assessment updated. Treat every recipe change as a new product until you have checked.
Insurance and records
Talk to a broker about product liability and public liability insurance. Many markets and shops will ask for proof. Keep batch records for every pour: date, recipe, ingredient suppliers and lot numbers, and the batch code on the label. If a customer reports a reaction, you can trace exactly what went into that bar.
Set up a safe, consistent workspace
Consistency is what separates a business from a hobby. Customers who love a bar want the next one to be identical.
- Dedicate your space. Use a clean area with good ventilation, washable surfaces and equipment used only for soap.
- Gear up for lye. If you make cold or hot process soap, wear eye protection, gloves and long sleeves, and keep lye away from children and pets.
- Use a recipe calculator. Check every cold or hot process recipe with a lye calculator and weigh ingredients on an accurate digital scale.
- Write standard recipes. Record exact weights, temperatures and steps for each product so every batch matches.
- Label and log batches. Give each batch a code and record it in a simple log.
- Cure and inspect. Cure bars on racks with airflow, then check every bar for texture, appearance and hardness before packing.
Cost and price your soap
Soap looks inexpensive to make, but costs add up once you include packaging, cure time, testing and safety work. Count everything.
- Oils, butters, lye or melt and pour base
- Fragrance or essential oils, colorants and additives
- Wrapping, labels and boxes
- Your time for making, cutting, curing, packing and selling
- A share of overheads: safety assessments, insurance, equipment, market fees and website costs
Soap costing template
Use this table for each product. All amounts below are made-up examples for illustration only.
| Product | Ingredients per bar (example) | Packaging (example) | Labor and overhead (example) | Total cost (example) | Retail price (example) | Wholesale price (example) |
|---|---|---|---|---|---|---|
| Oatmeal and honey bar | $0.90 | $0.40 | $1.30 | $2.60 | $9 | $4.50 |
| Charcoal and tea tree bar | $1.10 | $0.40 | $1.30 | $2.80 | $9 | $4.50 |
| Gift box of three bars | $3.00 | $1.60 | $2.40 | $7.00 | $26 | $13 |
Make sure your wholesale price still covers your full cost with a margin, and that your retail price leaves room for wholesale. Then check what comparable handmade soaps sell for locally and online, and decide where your brand fits.
Hypothetical example
Amira, based in Manchester, starts with three cold process bars. Before her first market she works with a safety assessor to get a CPSR for each recipe, names herself as Responsible Person and notifies each product on the SCPN portal. She keeps her descriptions simple, such as "unscented bar with olive oil", and avoids skin-condition claims. When a local gift shop asks for a fourth scent, she does not rush it. She tests the recipe, gets it assessed and adds it two months later with full paperwork in place.
Find buyers and keep them coming back
Soap is a consumable, so your real goal is repeat customers, not one-off sales.
- Markets and fairs. Let people see and smell your bars. Offer a small "try three" bundle to encourage new buyers.
- Online shop. Sell through your own site or a marketplace such as Etsy. Platform fees apply, so check Etsy's current fee schedule.
- Local wholesale. Gift shops, salons, spas, cafes and holiday rentals can be great stockists.
- Subscriptions and refills. A simple "new bar every month" or a reminder email when a bar is likely to be running out keeps customers loyal.
- Email marketing. In the US, include a clear unsubscribe option and a valid postal address. In the UK and EU, follow PECR and GDPR consent rules.
- Customer photos. Ask permission before you reuse a customer's photo of your soap on your website or social media.
Pro tip
Include a small card in every order explaining how to make a bar last longer, such as using a draining soap dish. Happier customers who get more value from each bar are more likely to buy again and recommend you.

Frequently asked questions
Is it legal to sell homemade soap?
In many places, yes, as long as you follow the rules where you sell. In the US, check whether your product is true soap or a cosmetic based on how you describe it. In the UK, soap used on skin generally needs a safety report, a Responsible Person and SCPN notification. Check local home business rules too.
Can I say my soap helps with eczema or acne?
Be very careful. Claims to treat or prevent a condition can change how your product is regulated and bring much stricter requirements. Most small makers stick to describing ingredients, scent and feel, and leave medical claims out entirely.
Is melt and pour soap a "real" handmade product?
Yes, many customers happily buy melt and pour soap, especially for gifts and designs. Be honest about your method in your descriptions, and note that the same safety and labeling rules apply to what you sell.
How many products should I launch with?
A small range of three to five bars is usually enough. It keeps testing, paperwork and stock manageable, and lets you learn what customers love before you expand.
