Ingredients explained
- Salicylic Acid
- Lipophilic BHA at 0.5-2%; exfoliant/sebum control, irritation/sensitization at high conc., photosensitivity (SPF needed), avoid sensitive/pregnant.
- Water/Aqua/Eau
- Primary aqueous solvent and carrier; no specific incompatibilities, focus on microbial stability.
- Alumina
- Alumina, inorganic abrasive/thickener; nano-grade requires inhalation risk assessment.
- Bentonite
- Natural clay for oil absorption in masks or thickening; no allergenicity, ensure high purity batches
- Kaolin
- Kaolin absorbent and bulk for powders/masks; check for heavy metals and comply with EU colorant limits IV/119
- Maltodextrin
- High-MW multifunctional excipient for thickening, binding, and emulsion stability; inert, non-penetrating conditioning.
- Propanediol
- Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Aloe Barbadensis Leaf Juice
- Natural humectant and soother with high water activity; requires preservative system, generally well-tolerated
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Titanium Dioxide
- Physical UV filter and colorant up to 25%; nano form requires attention
- Zinc Oxide
- Physical UV filter, 30% max in EU; oily at high levels, pair with oils for feel.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Polyacrylate Crosspolymer-6
- Water-soluble thickener; requires neutralizer, performs best at pH 5–7
- Polysorbate 20
- Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.
- Protease
- Protease for exfoliation; control pH and concentration to protect barrier, avoid strong acid/alkali.
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- T-Butyl Alcohol
- Fast-evaporating solvent; sharp odor and potential irritation at high levels, limit usage
- Triethoxycaprylylsilane
- Silane coupling agent at 0.1-0.5%; enhances inorganic filler adhesion, trace use, low toxicity, avoid direct contact with aqueous systems.
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
