The Formulator Home Lab

The Formulator Home Lab by So Good Co helps you explore small-batch DIY formulation drafts. Start with four free Skin starter routes, save and refine your draft, and export a PDF. Unlock Skin Lab for more pantry choices and goals, or add Soap Lab for educational cold-process and hot-process soap drafts.

YOUR FREE STARTING POINT Choose a cleanser, mist, face oil serum or balm route. Adjust the batch, explore ingredient substitutions, save an editable draft and return to your recent work. Free Skin PDF export does not require a purchase.

KEEP YOUR WORK ORGANIZED Save named drafts on your device. Record ingredient stock and purchase costs with explicit weight or volume units. Compatible stock can be deducted when you mark a batch made; missing, short or incompatible stock is reported.

OPTIONAL LAB UPGRADES Skin Lab is a one-time unlock for a richer pantry and additional guided choices. Soap Lab is a separate one-time unlock with NaOH calculations, oil and water weights, water discounts and prominent error and handling guidance. Soapmaking involves caustic lye and is intended for careful adults who understand protective equipment and responsible handling.

OPTIONAL INGREDIENT SCANNER Ingredient Scanner Monthly looks up barcodes in the on-device product catalog. Not every product is included. For unmatched products, subscribers can save package and ingredient-list photos locally. Saved photos remain available to view and export without an active subscription. Monthly subscriptions renew until canceled; the purchase screen shows the current price and terms.

IMPORTANT LIMITS Drafts are informational and educational. They are not laboratory-validated formulations, medical advice or a diagnosis. Preservation, finished pH, stability and shelf life require appropriate review and testing; refrigeration does not replace a validated preservative system. Hair + Scalp remains a preview, and Body Lab is not available as a finished lab.

The app does not require sign-in. Optional camera features open only when requested. Saved drafts and product photos stay on your device unless you choose to share them.
