terms that cross categories
Some concepts appear across multiple glossaries but mean different things in each context — or build on each other as a maker grows from hobby to business. These are worth understanding in full.
Fragrance load — candle vs. soap
In candles, exceeding the maximum fragrance load causes seeping and fire risk — the fragrance oil pools at the bottom of the vessel and can't bond with the wax. In cold process soap, the concern is different: high fragrance loads cause acceleration, where the batter thickens too fast to work with. Same concept, very different consequences. See both: candle fragrance load · soap fragrance load
Usage rate — fragrance, soap, and beauty
Usage rate is the recommended percentage of an ingredient relative to total formula weight. In candles it is called fragrance load. In soap it applies to both fragrance and additives. In bath and body products it governs actives, preservatives, and emulsifiers. Every makesy ingredient page lists the recommended usage rate for its product format.
Cure time — candles vs. cold process soap
Both candles and cold process soap require cure time — but for completely different reasons. Candle cure time (48 hours to 2 weeks) allows wax and fragrance molecules to fully bond, improving hot throw. Soap cure time (4–6 weeks) allows saponification to fully complete and excess water to evaporate, producing a harder, milder, longer-lasting bar.
Cold throw vs. hot throw — diffusers vs. candles
A reed diffuser's entire scent performance is measured in cold throw — passive evaporation at room temperature with no heat source involved. A candle, by contrast, has both a cold throw (unlit) and a hot throw (lit, heat-amplified). Understanding which throw type applies to a format changes how you select and load fragrance oil for it.
Castile soap — soap making vs. home cleaning
Soap makers think of castile soap as a finished bar or liquid product for skin cleansing. Laundry and home cleaning makers use the same castile soap as a concentrated cleaning base — diluted into all-purpose sprays, dish soap, and floor cleaners. One ingredient, two very different product categories, and different dilution and pH rules for each.
Business Glossary vs. Wholesale Glossary — what's the difference?
The Candle & Soap Business Glossary covers the maker-facing commercial vocabulary: pricing your products, choosing sales channels, branding, legal basics, shipping, and the makesy ecosystem. The Wholesale & Business Glossary goes deeper into the operational and strategic layer: sourcing, manufacturing models, pricing strategy for scale, retail buyer vocabulary, operations, finance, and legal compliance for growing brands. Start with the Business Glossary and graduate to Wholesale as your volume grows.
A lot of the confusion people hit early in making comes down to vocabulary. Not knowing what a term means — or misunderstanding it — leads to wasted materials, frustrating results, and products that don't perform the way they should. We built this glossary to remove that barrier. Every definition here is written with the practical meaning in mind: what you need to know when you're standing at a workbench deciding what to do next, not what you'd find in a chemistry textbook.
