Cold process soap labeling requirements
How you must label cold process soap depends on one question: is it being sold as plain soap, or does it make cosmetic claims? The answer decides which agency's rules apply, so settle it before you design the label.
The distinction that controls everything
The same bar of soap can fall into three different regulatory buckets:
- True soap — its cleansing comes from an alkali-fatty-acid reaction, and it is sold only as soap with no cosmetic or drug claims. True soap is exempt from FDA cosmetic rules and is regulated by the Consumer Product Safety Commission under the Federal Hazardous Substances Act.
- Cosmetic soap — it is marketed as moisturizing, exfoliating, deodorizing, anti-aging, or for fragrance and skin benefits. Those are cosmetic claims, so the product is a cosmetic and must meet FDA cosmetic labeling rules.
- Drug soap — it claims to treat acne, kill germs, relieve eczema, or similar. Those are drug claims and trigger OTC Drug Facts labeling beyond the scope of this page.
Most handmade cold process soap that mentions skin benefits or fragrance lands in the cosmetic bucket.
If it is a true soap (CPSC / FPLA)
A true soap label must carry an identity statement ("soap"), a net-weight statement in dual units, and the name and place of business of the maker or distributor under the Fair Packaging and Labeling Act (16 CFR Part 500). An INCI ingredient declaration is not federally required for true soap, though many makers list ingredients voluntarily.
If it makes cosmetic claims (FDA / FPLA / MoCRA)
Cosmetic soap must carry the full cosmetic label set: the statement of identity, the net quantity of contents in dual units, the name and place of business, the ingredient declaration in INCI names in descending order of predominance (21 CFR 701.3), the MoCRA adverse-event contact on the label, and a California Prop 65 warning where required.

Does cold process soap need an ingredient list?
If the soap makes cosmetic claims it must list ingredients in INCI names in descending order of predominance. A true soap sold only as soap is not federally required to, though many makers list ingredients voluntarily.
What makes soap a cosmetic instead of just soap?
Cosmetic claims. If the soap is marketed as moisturizing, exfoliating, deodorizing, anti-aging, or for fragrance or skin benefits, it is a cosmetic and must meet FDA cosmetic labeling rules. Plain soap sold only as soap is regulated by the CPSC instead.
Does MoCRA apply to handmade cold process soap?
MoCRA applies to cosmetics. Handmade soap that makes cosmetic claims is a cosmetic and must carry the MoCRA on-label adverse-event contact. A true soap with no cosmetic claims is not a cosmetic and falls under CPSC rules instead.
What must a true soap label include?
An identity statement (soap), a net-weight statement in US customary and metric units, and the name and place of business of the maker or distributor under the FPLA.
