Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Stearic Acid
- Fatty acid emulsifier, white waxy solid; adds slip feel
- Myristic Acid
- Saturated fatty acid, saponification feedstock; insoluble alone, pairs with stearic acid.
- PEG-32
- Not decoded yet
- Potassium Hydroxide
- Strong alkali pH adjuster, trace usage (<0.1%); corrosive, must be neutralized.
- Palmitic Acid
- Palmitic acid for emulsification/emollient; solid fat, high melting point, occlusive.
- Lauric Acid
- Lauric acid for cleansing and emulsification; high comedogenic rating, recommend limiting to 1-2% or combining with other acids.
- Glyceryl Stearate
- Emulsifier at 1-3%; may require acid to prevent saponification
- PEG-100 Stearate
- Non-ionic emulsifier, requires ionics for stability; check PEG for formaldehyde.
- Lauramide Dea
- Cocamide DEA, foam booster/thickener; sensitizing, restricted in EU (≤0.3%); consider alternatives.
- Cocamidopropyl Betaine
- Cocamidopropyl betaine; zwitterionic co-surfactant reducing irritation and boosting foam, common in mild cleansers.
- Lavandula Hybrida Oil
- Essential oil for emollience and fragrance; contains allergens like linalool, requires EU 26 labeling
- Pinus Sylvestris Leaf Oil
- Pine leaf oil, woody scent; contains peroxides and monoterpenes, may irritate sensitive skin, add at low temps and control total load.
- Potassium Cocoate
- Soap-type anionic surfactant for cleansing and emulsifying; watch pH and skin tolerance.
- Salicylic Acid
- Lipophilic BHA at 0.5-2%; exfoliant/sebum control, irritation/sensitization at high conc., photosensitivity (SPF needed), avoid sensitive/pregnant.
- Asiaticoside
- Plant glycoside, healing and antioxidant; poor solubility, use low levels with solubilizers.
- Asiatic Acid
- Pro-healing active, 0.1–1%; stability affected by light, store protected from light.
- Madecassic Acid
- Madecassoside hydrolysis product for barrier repair and anti-inflammatory action; mild, low typical usage
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
