How it works
From idea to batch in 3 steps
- 1
Pick your base
Start from a balanced, tested preset — butters, balms, scrubs, oils, creams and more.
- 2
Customize & balance
Swap ingredients and adjust percentages while guardrails check emulsifiers, preservatives and IFRA limits.
- 3
Scale & pour
Get exact batch weights in grams or ounces, step-by-step phases, and a shareable recipe card.
Melanin-first
100+ ingredient profiles annotated for melanated skin and coily/curly hair — barrier support, porosity and comedogenic ratings, not generic advice.
What's inside the OS
Every tool a formulator needs.
Formulate
Guided builders for body butter, hair butter, lotion, cleanser and more.
Calculate
Emulsifier balance (HLB), pH, saponification, shelf life, stability, batch scaling and costing.
Check safety
Comedogenic scores, essential-oil safety limits (IFRA, the fragrance industry's standards), active compatibility and allergens.
Ingredient intelligence
A 320-ingredient library with 100+ profiles annotated for melanated skin, official label names (INCI) and category browsers.
Build a brand, not just a batch
What independent brands need to launch with confidence
- Stand out in the marketCreate original formulas that belong to your brand, not a recipe everyone copied from the same blog. Your formulas stay yours.
- Know every ingredientA 320-ingredient library with 100+ profiles annotated for melanated skin and coily/curly hair, so you choose ingredients on purpose, not by trend.
- Tailored to your productDial in texture, scent, and ingredients with the formula builders, the butter texture tool, and the fragrance pyramid.
- Compliance guidance, not approvalThe FDA does not approve cosmetics before they are sold. Our guides walk you through what is required: facility registration and product listing (unless you qualify for the small-business exemption), safety substantiation records, serious adverse-event reporting within 15 business days, and label rules. You file and remain responsible; we do not file, certify, or approve anything for you.
- Scale as you growStart with a small test batch, then scale up with the batch scaler. Every plan includes INCI labels, batch logs and version history; Studio adds per-unit costing.
