- Cupuaçu butter — close on silky finish, no wax behaviour.

- Cetyl palmitate — slightly firmer, more wax-like feel.
- Cetyl alcohol — more creamy, less wax character.
- Stearyl palmitate — firmer, higher melting point.
- Behenyl alcohol — firmer feel, more conditioning.
- Jojoba wax esters — softer, slightly more buttery feel.

- Stearic acid — closest substitute, slightly firmer feel.
- Cetearyl alcohol — different chemistry (fatty alcohol), similar texturing role.
- Behenic acid — longer chain, firmer feel.
- Beeswax — natural wax alternative for structure.
- Cetyl palmitate — wax-ester form that gives smoother slip with similar body.

- Candelilla wax — slightly softer, less glossy, use 80-90% of the rice bran amount.
- Carnauba wax — harder, higher melting, glossier.
- Beeswax — softer, tackier, honey-scented; not vegan.
- Sunflower wax — similar hardness, slightly higher melting.

- Cetyl palmitate — softer, lower melting point, more silky than firm.
- Myristyl myristate — softer still, more "melt-on-skin."
- Behenyl alcohol — similar firmness, slightly different feel.
- Beeswax — firmer, more structured, different scent.
- Rice bran wax or candelilla wax — plant-based alternatives for stick structure, slightly different texture.

- Rice bran wax — close on hardness and melt point, very similar use.
- Candelilla wax — softer, slightly lower melting, use 1.2-1.5x the amount.
- Carnauba wax — harder, glossier, use 70-80% of the sunflower amount.
- Beeswax — softer, tackier, honey-scented; not vegan.

- Hydrogenated vegetable oil — broader family, similar role, less precise feel.
- Stearyl palmitate — similar firmness, slightly different feel.
- Behenyl alcohol — closely related, fatty alcohol form, also conditioning.
- Cetyl palmitate — softer wax-ester alternative.
- Glyceryl behenate — similar fatty acid, monoester form, more emulsifying than structural.

- Lactic acid — gentler AHA, also good for pH.
- Glycolic acid — stronger AHA, sharper pH effect.
- Malic acid — closely related fruit acid, similar role.
- Tartaric acid — gentle fruit acid, less common but works for pH.

- Sodium hydroxide (NaOH) — for hard bar soap and most pH adjustment.
- TEA (triethanolamine) — gentler synthetic base for pH.
- Arginine — natural amino acid base for pH neutralization.
- Sodium hydroxide solution (50% commercial) — pre-dissolved version, less safe but ready to use.

- Potassium hydroxide (KOH) — used for liquid soap; produces soft potassium soaps.
- Triethanolamine (TEA) — gentler base for carbomer; synthetic, less natural positioning.
- Arginine — natural amino acid base, used for carbomer neutralization.
- Sodium carbonate (washing soda) — much milder, smaller pH shift.
