There's no federal definition of "natural" for personal care products. No threshold a formula has to clear, no standard to meet, and no agency checking. Any manufacturer can put the word on any product, and most of them do.
That leaves you in an awkward spot. The claim carries real commercial weight with shoppers and almost no informational weight for the brand buying production. Two manufacturers can describe themselves in identical language while one holds audited certifications and the other holds an opinion. If you're building on ingredient quality, the useful skill isn't detecting sincerity on a sales call. It's knowing which documents to ask for, and what each one does and doesn't prove. That's the conversation Botanie tends to have on a first call.

In Short
Natural is unregulated in US personal care, so it tells you nothing on its own and can't be substantiated if a retailer or a regulator asks. What can be substantiated is narrower and more useful: third-party certifications with published standards and audit trails, disclosed organic content percentages by weight, and ingredient documentation running back down the supply chain. USDA National Organic Program certification and Leaping Bunny certification show up most often in this category, and NSF/ANSI 305 exists specifically because food-oriented organic rules don't translate cleanly to soap. A natural soap manufacturer worth signing hands over the paperwork without being pressed. One that answers the question with adjectives is telling you what it doesn't have.
"Natural" Has No Legal Definition. Here's What Does.
Start with classification, because it decides which rulebook applies to you. Per the FDA, a product counts as soap only if it's composed mainly of alkali salts of fatty acids, if those salts are the only source of the cleaning action, and if it's labeled and marketed only as soap. Meet all three, and you're regulated by the Consumer Product Safety Commission rather than the FDA.
Almost no brand stays inside that box, and that's a deliberate choice. The FDA counts a product intended for "moisturizing the skin, making the user smell nice, or deodorizing the user's body" as a cosmetic. Those are the claims that sell, so most brands accept cosmetic status and the obligations that come with it.
Notice what's missing from all of those thresholds. None of them mention the word natural. The regulatory system cares about what you claim your product does, not how wholesome the ingredient list reads, which is exactly why your substantiation has to come from somewhere else.
Three sources do the real work: certification bodies with published standards, disclosed organic content percentages by weight, and ingredient documentation that runs back to the supplier. Everything else is marketing.
The demand justifying that effort is real. Grand View Research projects US organic personal care to grow from $6.88 billion in 2025 to $14.58 billion by 2033, with shower and bath the fastest-growing segment at 10.8 percent annually.

The Certifications That Carry Weight
Three standards come up repeatedly in natural soap, and each proves something different. Knowing which is which keeps you from overstating a claim you can't back.
USDA National Organic Program
NOP is the strictest option, and the one retailers recognize instantly. Administered through accredited certifiers, it governs agricultural ingredients and the handling operations that process them, and it requires documentation at every step of the chain.
Its limitation is scope. NOP was built for food, and its rules don't map neatly onto a chemical reaction like saponification.
NSF/ANSI 305
This standard closes that gap. Established in 2009 as the American National Standard for organic claims in personal care, NSF/ANSI 305 requires at least 70 percent organic content by weight, requires the exact percentage on the label, and permits the limited chemical processing soap needs. As NSF puts it, soaps with organic ingredients "are permitted to undergo chemical processing known as saponification, without which these products could not lather."
Leaping Bunny
Leaping Bunny is the cruelty-free standard with teeth. The Leaping Bunny Standard requires a Fixed Cut-off Date applied across a company's entire product range, a supplier monitoring system backed by written Declarations of Product Compliance and Raw Material Compliance, independent third-party audits, and annual recommitment. It's ongoing work, not a one-time badge.
Here's how the three compare, plus the word everybody uses.
| Standard | What it proves | What it doesn't cover |
|---|---|---|
| USDA National Organic Program | Certified organic agricultural ingredients and certified handling, documented at every step | Chemical processing steps specific to personal care, including saponification |
| NSF/ANSI 305 | At least 70 percent organic content by weight, with the exact percentage disclosed on the label | Animal testing policy, and it isn't the same credential as NOP certification |
| Leaping Bunny | No animal testing across the full product range, verified by supplier declarations and independent audit | Ingredient quality, organic content, or anything about formulation |
| "Natural" | Nothing. There's no standard, no threshold, and no auditor behind it. | Everything above |
One more thing worth getting right. Plant-based and vegan are product attributes rather than certifications. Both are fine to state when they're true, and listing them beside audited standards is the error that gets flagged in a retailer review.
What to Ask a Natural Soap Manufacturer For, in Writing
Six documents tell you more than any capabilities deck, and all six are reasonable to request on a first call.
Ask for the certificate itself, with the certifier named and the scope stated. A manufacturer certified for some products and not others is common and perfectly fine, as long as you know which side your blend falls on.
Ask for the organic content percentage by weight for your formula, not the flagship formula, in a number you can check. Ask for the ingredient listing in both common language and INCI, which is faster to evaluate than a sales conversation and much harder to fudge. Botanie publishes organic percentages and INCI listings per product for exactly that reason.
Ask how harvest variation gets handled. Natural inputs are agricultural, and color, scent intensity, and hardness genuinely shift between crops. A partner who raises this before you do has managed it before.
Ask what the facility won't make. A narrow offer is usually what makes deep certification possible, because every additional process is another chain to document. And ask who holds the substantiation records, since MoCRA requires records adequately substantiating product safety, and it's worth knowing whose file that lives in.
Where Natural Formulation Gets Operationally Hard
This is the honest answer to why certified natural production prices are above commodity, and it isn't really about sourcing. It's about time and variability.
Curing isn't negotiable. Cold process soap finishes saponification on its own schedule, and that time sits inside your lead time whether or not your launch calendar has room for it. Any manufacturer promising to compress it is compressing something you'll notice in the bar.
From-scratch production retains the glycerin, and it gives a formulator real control over the oil profile. That control is the whole argument for the process, and it's also why it takes longer than buying a base.
Scenting with essential oils and plant extracts adds iterations. Strength varies between batches, and the same oil behaves differently in a hot soap batter than it does in a test pour. That's a real part of why development runs a quarter rather than a month.
Certification is permanent overhead rather than a milestone. Annual recommitment, refreshed supplier declarations, and continuous inspection are what you're actually paying for when you buy from a certified facility.
The regulatory floor is also still being built. Final Good Manufacturing Practice regulations and fragrance allergen labeling rules hadn't been issued as of early 2026, according to Foley & Lardner. Manufacturers already operating to an audited standard tend to absorb new requirements without disruption, which is worth weighing when you pick a partner you plan to keep.
Want to see the documentation before you commit? Certificates, scopes, and organic percentages are all fair to ask for up front. See what Botanie holds.
Three Claims That Won't Survive a Retailer Audit
- "All natural ingredients." There's no standard behind it, so there's nothing to produce when a buyer asks for substantiation. Replace it with the certification and the organic percentage, both of which are checkable.
- "USDA Organic, Leaping Bunny, and vegan certified." Two of those are audited certifications, and one is a product attribute. Listing them together is the mistake that draws a correction request, and it undermines the two claims that are real.
- "Certified organic," full stop. Certification has a scope. If the certificate covers some blends but not yours, the claim doesn't carry over to your carton. Ask which side your formula sits on before you print.
How Botanie Handles the Natural Question
Botanie has held both certifications since 2008: USDA National Organic Program certification administered by Oregon Tilth, and Leaping Bunny certification, continuously since the same year.
Organic content is published per product rather than described in general terms. Bar soaps run 85 percent organic content, castile and foaming soaps land in the 81 to 82 percent range, and organic ingredients are marked in the listings. Ingredient lists appear in common language and in INCI for both raw and finished product, which is the resolution that makes a claim checkable rather than merely stated.
Formulas are built from oils, butters, and botanicals, scented with essential oils and plant extracts, and cut to 25 sizes from .6 to 7.6 ounces. Minimums are sized for brands the large manufacturers turn away: bar first orders at 2,160, splittable into two blends of 1,080; reorders at 1,080 per blend; liquid from 50 gallons; and shampoo bars at 3,500 per blend.
The exclusions protect the certified chain. Botanie doesn't make melt-and-pour, extruded or triple-milled bars; novelty shapes; clear glycerin novelty soaps; OTC drug products; or liquid detergents such as shower gel and dish soap.
Conclusion
A natural soap manufacturer isn't defined by how it describes itself. It's defined by what it can hand you when a retailer, a regulator, or a skeptical customer asks the obvious follow-up question.
Certificates with named certifiers, organic percentages by weight, INCI listings, supplier declarations, and a clear statement of what the facility won't produce are the entire substance of the thing. Everything else is adjectives, and adjectives don't survive an onboarding review.
Botanie has made all-natural cold process bar soap, shampoo bars, and true liquid soap in Missoula, Montana for more than two decades, and works with 500+ brand partners who need the documentation to hold up. Ask for the file on the first call, and your shortlist gets short quickly.
