- Petrolatum (petroleum jelly) — similar occlusive gel texture, but petroleum-derived.
- Aloe vera gel (high concentration) — water-based gel, but much thinner and different skin feel.
- Hydroxyethyl cellulose gel — water-based thickener, but produces a different, more mucilaginous texture.

- Copaiba essential oil — the distilled version, lighter and less complex, lower usage rate (0.5-2%), lacks the diterpene acid fraction but retains the beta-caryophyllene.
- Frankincense resin oil (CO2 extract) — similar resinous character, anti-inflammatory and wound-healing, different terpene profile.
- Tamanu oil — different chemistry entirely (a true fatty oil with calophyllolide), but occupies a similar niche in wound-care and anti-inflammatory formulas.
- Black pepper CO2 extract — another source of beta-caryophyllene, warming sensation, used in pain-relief blends.

- Decyl Glucoside — slightly heavier, more cleansing, less effective as a solubilizer. Use when you want more cleaning power and less clarity work.
- Polyglyceryl-4 Caprate / Polyglyceryl-6 Caprylate — premium PEG-free solubilizers, more expensive, slightly better at solubilizing heavy essential oils.
- Polysorbate-20 or Polysorbate-80 — classic synthetic solubilizers, very effective, but PEG-based and therefore off-label for certified-natural formulas.

- Coco Betaine — almost identical, slightly more 'natural' label appeal, slightly higher impurity risk in low-grade batches. The most common direct swap.
- Sodium Lauroamphoacetate — milder, slightly less foam-boosting, better choice for very sensitive skin or eye-area cleansers.
- Disodium Cocoamphodiacetate — the gentlest of the amphoterics, used in premium baby washes, more expensive and harder to source.

- Cocamidopropyl Betaine — almost identical performance, slightly more refined, very slightly milder on sensitive skin, more common in commercial formulas. The standard swap.
- Sodium Lauroamphoacetate — milder still, less foam-boosting, a step up in mildness for ultra-sensitive products like eye-area cleansers.
- Disodium Cocoamphodiacetate — premium baby-shampoo grade, very gentle, less foam, more expensive.

- Decyl Glucoside — lighter, thinner, cleaner foam, very slightly less conditioning. The direct swap when you want less viscosity.
- Lauryl Glucoside — thicker, more viscosity-building, slightly less mild but still very gentle. Use when you want a glucoside that thickens the formula.
- Caprylyl/Capryl Glucoside — much lighter, doubles as an essential-oil solubilizer, less foam. Use in toners, mists, and clear cleansers.

- Coco Glucoside — very similar, slightly thicker, slightly creamier foam, gentler conditioning feel. The closest direct swap.
- Lauryl Glucoside — thicker, more viscosity-building, slightly less mild. Use when you want a glucoside that also thickens.
- Caprylyl/Capryl Glucoside — even lighter, also a solubilizer for essential oils, thinner foam. Use in toners and micellar waters.

- Cocamidopropyl Betaine — workhorse secondary surfactant, very common.
- Coco-Glucoside — non-ionic mild secondary surfactant.
- Decyl Glucoside — non-ionic mild secondary surfactant.
- Sodium Cocoyl Glutamate — primary or secondary mild surfactant.
- Coco-Betaine — closely related to cocamidopropyl betaine.

- Coco Glucoside — slightly thinner, slightly milder, creamier foam. Use when you want less viscosity and slightly more gentleness.
- Decyl Glucoside — thinnest, mildest, cleanest foam. Use for face and baby formulas where viscosity is not the goal.
- Caprylyl/Capryl Glucoside — much thinner, doubles as an essential-oil solubilizer. Different use case (toners, sprays), not a direct swap.

- SCS (Sodium Coco-Sulfate) — much cheaper, stronger cleansing, fluffier foam, more drying. Swap this in only if cost is the priority and you can compensate with more conditioning agents.
- SLSA (Sodium Lauryl Sulfoacetate) — similar mildness, much fluffier foam, slightly easier to dissolve. Use for bubble bars or kids' products.
- Sodium Cocoyl Glutamate / Sodium Lauroyl Glutamate — even gentler, amino-acid based, lower foam, more expensive ($18-22/kg). Best swap for very sensitive skin.

- SCI (Sodium Cocoyl Isethionate) — much milder, creamy lotion-like foam instead of fluffy bubbles, more expensive (about double the price), gentler on the scalp. Use this if your customer has sensitive skin.
- SLSA (Sodium Lauryl Sulfoacetate) — similar foam volume to SCS, much milder, large molecule that does not penetrate skin. Better for bubble bars and bath products, slightly pricier.
- Sodium Cocoyl Glutamate — amino-acid based, the mildest of the realistic swaps. Foams less, costs more (around $18-22/kg), but a beautiful choice for facial cleansers and baby shampoos.

- SCS (Sodium Coco-Sulfate) — much cheaper, stronger cleansing, similar foam volume but slightly less fluffy, more drying. Use for shampoo bars where cost matters.
- SCI (Sodium Cocoyl Isethionate) — milder, creamier (not bubblier) foam, better for face and baby products, more expensive.
- Sodium Cocoyl Isethionate + a foam booster like coco glucoside — a softer, more luxurious feel with decent foam, but never matches SLSA's bubble volume in bath products.

- SCI (Sodium Cocoyl Isethionate) — milder, more skin-friendly, common in syndet bars.
- Sodium Coco-Sulfate (SLS-derived from coconut) — different chain spec, related.
- Sodium Lauryl Sulfoacetate (SLSA) — milder, more expensive.
- Sodium Cocoyl Glutamate — gentle amino-acid surfactant, very mild.

- Sodium cocoyl glutamate — another amino acid-based anionic surfactant with similar mildness. Slightly different foam character, widely available.
- Sodium lauroyl methyl isethionate — very mild, sulfate-free anionic with a creamier foam. Popular in facial cleansers.
- Coco-glucoside — a nonionic glucoside surfactant, extremely mild, though the foam profile is lighter and less creamy.
- Disodium cocoyl glutamate — the disodium form of cocoyl glutamate, even milder, often used in combination with its monosodium counterpart.
