How to find a cosmetic chemist — without losing your IP.

• Freelance independent chemist. $80–$200/hr or $4k–$25k per formula. Best for one-SKU custom work; you own IP if the contract says so.
• Contract manufacturer's in-house lab. "Free" — bundled with production. The catch: the manufacturer owns the formula and can sell it to others.
• Boutique formulation lab. $15k–$80k per formula, full development + stability. Best fit once you're scaling and want exclusive IP without committing to one CM.

• Society of Cosmetic Chemists (SCC) directory — vetted professionals by region.
• Cosmetics & Toiletries trade publications and conference attendee lists.
• LinkedIn search for "cosmetic chemist" + your category (sun care, retinol, body).
• Referrals from your packaging supplier — they know who actually ships.

Skip Fiverr and Upwork for active formulation. Plenty of "consultants" there; almost no production chemists.

Before any work begins, get in writing: who owns the formula, who can sell it, and what happens to the bench notes if you leave the manufacturer. A standard work-for-hire clause assigning all rights to your company is the floor.

If the chemist or manufacturer pushes back, the formula isn't really yours — and your "brand" is renting its core asset.

Bring: hero claim in one sentence, three benchmark products to dupe or beat, target retail price, target margin, regulatory market (US / EU / Health Canada — they differ), preferred actives and any hard "do not include" list, and texture/sensorial direction in plain language.

Vague briefs produce vague formulas. Tight briefs produce hero SKUs.

• Won't sign an NDA before discussing the brief.
• Quotes a formula without stability testing in scope.
• "I have a great base I use for everyone" — that's PLR, not custom.
• No references you can call.
• Vague on timeline ("a few months").
