Worth knowing
- Caution: Hot lye scorches it: it darkens and can smell burnt or of ammonia. Keep it cold, and keep the soap cool so it does not gel. Lovely Greens supplier or guide
- Danger Its sugars, heated above 84 °C with lye, can give off toxic carbon monoxide. Keep it cool and work where air moves. NOAA CAMEO Chemicals primary source
- It spoils fast: keep it cold and use it within days. Too much in the bar can grow mould. The Nerdy Farm Wife supplier or guide

David Fisher, The Complete Photo Guide to Soap Making (Creative Publishing International, 2018), p. 20: dyes "give a full range of hues—from subtle to bright and bold", but "can bleed between layers or swirls of soap, especially in melt-and-pour soap. Some are not stable in cold process soap, so test them first"; oxides "are very stable and strong in soap". Natural colours, pp. 82–84. In an infused oil: "Annatto: yellow-orange"; "Alkanet: light to deep purple, depending on the amount used"; "Paprika: orange-peach". In the lye solution: "Indigo: light to deep blue"; "Madder root: pinkish-red"; "Rose clay: deep rose pink". Added to the oils or at trace: "Activated charcoal: light gray to deep black"; "Black walnut hull (ground): speckled brown, also an exfoliant"; "Calendula flower petals (whole or ground): nice, warm yellow"; "Carrots (puréed or juiced): muted orange"; "Cinnamon: reddish tan to brown"; "Cocoa powder: tan to brown"; "Cucumber: pale yellow-green"; "Rosehips (ground): speckled reddish brown"; "Sage: muted green"; "Spirulina: pastel green/blue-green". For "a bright, white bar of soap": "Add titanium dioxide: about 1 teaspoon per 1 pound (454 g) of oils."
The Nerdy Farm Wife, carrot soaps: soaps "using 100% carrot juice"; fresh juice keeps "a day or two, when refrigerated, but you can freeze it".
Lovely Greens, natural soap additives: pumpkin purée "1 oz (28 g) ... for every pound (454 g) of soapmaking oils"; aloe in hot lye "can burn".
