The whole run in one place: an all-purpose, laundry or dish recipe in percentages or grams, every batch traced by lot, the fragrance allergens to declare surfaced, the hazard-label cues laid out, and the cost per bottle known before you price it. Advisory, never a certification.
Work a surfactant blend as percentages of the batch, or as actual weights — Alchemis keeps both consistent. Change one ingredient and the rest redistribute; lock the ones you don't want touched. Scale a 1 L test up to a 20 L run and every quantity comes with it.
Each production run gets a lot number, a make date, and production steps — with ingredients assigned to the step they're added at, and per-step splits when you dilute or divide. Photos from along the way and an activity log, then finished bottles carry the lot, so you always know what went into which.
Cleaners fall under the EU Detergents Regulation 648/2004. As you formulate, Alchemis lists the fragrance allergens that reach the pack at or above 0.01%, and the always-list perfume and preservative wording (Annex VII A.2 / A.3). It also reminds you of the duties you complete yourself — the public ingredient data sheet and its URL on the pack, the constituent weight-band lists, and dosage instructions. Guidance, never a certification.
Best-effort guidance to catch issues early, never a certification. The ingredient data sheet, its URL on the pack, weight-band lists and dosage remain your duties. Always defer to your own supplier documentation and a qualified assessor.
A cleaner is a chemical mixture under CLP, so it carries a hazard label. Alchemis suggests the block by product category — the GHS07 pictogram, the word Warning, a hazard statement like H317, and EUH208 for the sensitising fragrance — with reminder notes about your PCN/UFI and safety data sheet. Confirm the real classification against your ingredient SDSs and an assessor.
These are advisory cues, not a CLP classification. SDS authoring is coming soon — for now Alchemis gives guidance notes only, and it does not handle REACH. Verify the pictograms, H- and EUH-phrases, PCN and UFI with your SDSs and a qualified assessor.
Surfactants, acids, fragrance, the bottle and the trigger — every cost rolls up from your supplier prices into a per-bottle COGS. Set a margin or a markup and Alchemis suggests the selling price, so you price from the real number instead of a guess. Direct sales and consignment are both tracked.
Recipes, batch tracking, the allergens to declare, hazard-label cues and cost per bottle — for cleaners and five other crafts. Advisory, never a certification. Free forever for hobbyists.
