Formulation view Aqueous gel mask leveraging glycerin and sodium hyaluronate for hydration, enriched with colloidal gold and caffeine. Thickened with carbomer neutralized by sodium hydroxide, preserved with a phenoxyethanol and potassium sorbate system. Designed for soothing and circulation improvement, ideal for rescue care. Factory observation: Uniform dispersion of gold particles is critical to prevent sedimentation, and precise pH control during neutralization is essential.

Ingredients explained
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Water/Aqua/Eau
- Primary aqueous solvent and carrier; no specific incompatibilities, focus on microbial stability.
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Caffeine
- Active ingredient, 0.1–2%; promotes circulation, irritation risk at high concentration.
- Olivine Extract
- Mineral extract rich in silicate; acts as skin conditioner, limited published irritancy data.
- Colloidal Gold
- Colloidal gold particles used for color or claimed antimicrobial/soothing effects; monitor metal ion migration and potential toxicity.
- Pentylene Glycol
- Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- Sodium Metabisulfite
- Antioxidant/preservative at 0.05–0.2%; irritating for sensitive skin, avoid with oxidizers
- Mica
- Mineral colorant for pearlescence; heavy metal screening required
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Gold
- Gold in nano or microparticle form, for coloring and slip; usage restricted by regulations
- Iron Oxides
- Inorganic pigment for color; particulate form, inhalation risk low in cosmetics.
- Titanium Dioxide
- Physical UV filter and colorant up to 25%; nano form requires attention
