Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Myristic Acid
- Saturated fatty acid, saponification feedstock; insoluble alone, pairs with stearic acid.
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Stearic Acid
- Fatty acid emulsifier, white waxy solid; adds slip feel
- Potassium Hydroxide
- Strong alkali pH adjuster, trace usage (<0.1%); corrosive, must be neutralized.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Palmitic Acid
- Palmitic acid for emulsification/emollient; solid fat, high melting point, occlusive.
- Glycol Distearate
- Glycol distearate for thickening and emulsification; non-ionic, improves viscosity
- Lauric Acid
- Lauric acid for cleansing and emulsification; high comedogenic rating, recommend limiting to 1-2% or combining with other acids.
- Disodium Lauryliminodiacetate
- Not decoded yet
- Sodium PEG-4 Cocamide Sulfate
- Not decoded yet
- Lauramide Dea
- Cocamide DEA, foam booster/thickener; sensitizing, restricted in EU (≤0.3%); consider alternatives.
- Sorbitan Stearate
- Non-ionic emulsifier for O/W systems; hydrophobic, requires co-emulsifiers, inert at high purity
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Methylparaben
- Preservative, narrow spectrum; often combined, check allergen risk and regulatory limits.
- Etidronic Acid
- Etidronic acid chelator, restriction III/53 (<0.01%); binds metal ions to prevent oxidative discoloration.
- Tetrasodium EDTA
- Chelator removing metal ions to enhance antioxidant and preservative efficacy; very low usage, typically 0.05-0.1%, no direct skincare function.
- Propylparaben
- Medium-chain preservative; restricted use, pH-sensitive efficacy.
- Olive Oil
- Plant oil base providing emolliency and occlusion; high PUFA content requires antioxidants to prevent oxidation.
- Citrus Aurantium Dulcis Juice
- Not decoded yet
