Your numbers
Formula lines and batch target
Use the filled example first. Then replace each field with a measured value or your best current estimate.
Step 1Answer one question at a time. Your example values stay available.
Important limit
Correct arithmetic does not establish a safe or stable cosmetic.
Use supplier-confirmed INCI names, permitted use levels, phase instructions, pH limits, preservation, compatibility, stability, microbial, packaging, safety, claims, and market-specific review before sale.

How to use the Cosmetic Formula Phase & Batch Sheet
Scale percentages and organize water, oil, and cooldown phases. The calculator runs privately in your browser and is designed to make the assumptions behind the answer visible.
What to have ready
Use exact formula weights plus supplier-confirmed INCI names, use ranges, phase instructions, pH limits, and compatibility information.
Key inputs: Ingredient entries; Target batch weight; Transfer and process allowance.
How to use the result
Use the result as a bench-trial or label draft. Supplier instructions, stability, preservation, safety, and market-specific review still control the finished product.
