Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Squalane
- Emollient from plants or synthetic; light texture
- Polysorbate 20
- Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Isopropyl Myristate
- Light synthetic ester, fast-drying and non-greasy; high comedogenic risk, limit in acne-prone skin
- Quartz
- Mineral abrasive for physical exfoliation; particle size and polish critical, high hardness may damage stratum corneum.
- Sodium Carbomer
- Carbomer sodium, strong gelling agent; requires neutralization, high thickening power, may interact with cationic actives.
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Hexylene Glycol
- Polyol solvent and humectant with penetration enhancement; limit concentration to avoid irritation, no specific allergen tag
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
