Formulation view Clay mask using kaolin, diatomaceous earth, and silica for high oil absorption, combined with tea seed extract and salicylic acid. Carbomer provides texture; hydroxyacetophenone supports preservation. Ideal for oily skin deep cleansing. Factory observation: monitor diatomaceous earth dust exposure and kaolin heavy metal compliance during production.

Ingredients explained

Water

Primary solvent and base; requires preservative system to prevent microbial growth

Silica

Silica powder at 1–10%; absorbs oil, thickens, provides matte finish, for oil-control products

Propanediol

Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative

Kaolin

Kaolin absorbent and bulk for powders/masks; check for heavy metals and comply with EU colorant limits IV/119

Glycerin

Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives

Diatomaceous Earth

Diatomaceous earth for oil absorption/opacification at 1–5%; high surface area, handle dust carefully.

1,2-Hexanediol

Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives

Butylene Glycol

Polyol humectant and solvent at 1–5%; aids solubilization, light feel

Camellia Sinensis Seed Extract

Tea seed extract with oils/polyphenols; humectant/conditioner/scent, control concentration due to lipid content.

Betaine

Betaine for mild moisturizing/surfactant; low concentration 1-2% common, high may irritate.

Carbomer

Gelling thickener requiring neutralization; watch out for ion compatibility

Tromethamine

pH adjuster, alkaline; precise dosing required

Hydroxyacetophenone

Hydroxyacetophenone as antioxidant; often boosts Vitamin C, works in acidic pH.

Titanium Dioxide

Physical UV filter and colorant up to 25%; nano form requires attention

Ammonium Acryloyldimethyltaurate/VP Copolymer

Cationic polymer providing suspension, thickening, and conditioning; often paired with anionic thickening systems, low usage, imparts slip.

Cellulose

Plant-derived thickener at 0.1–1%; requires full hydration, poor cationic compatibility

Charcoal Powder

Charcoal; adsorbs impurities/oil for cleansers, provides opacity, can be drying or matte.

Calamine

Mineral powder for absorbing, opacifying and protecting skin; low irritation at low levels.

Cellulose Gum

Cellulose gum, water-soluble thickener/stabilizer; may destabilize with cationics, hydrate first.

Xanthan Gum

Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration

Silica Dimethyl Silylate

Dimethicone modified silica for dry touch; anti-caking and oil absorption

Disodium EDTA

Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy

Ethylhexylglycerin

Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel

Ethylcellulose

Water-insoluble film former and viscosity builder for suspensions; requires dispersion or premixing.

Gardenia Florida Fruit Extract

Extract for color and conditioning; watch dark batches in clear systems

Dextrin

Polymer thickener and binder from starch fermentation; biodegradable, hygroscopic, may affect powder flow

Lauric Acid

Lauric acid for cleansing and emulsification; high comedogenic rating, recommend limiting to 1-2% or combining with other acids.

Zea Mays Starch

Corn starch for oil absorption and suspension; powder, hygroscopic, needs moisture control

Aluminum Hydroxide

Aluminum hydroxide for emollient/thickening; opacifier, used in antiperspirants, particulate risk.

Mannitol

Polyol humectant with binding/skin conditioning properties; high levels may cause osmotic irritation

Hyaluronic Acid

High-water-binding humectant at 0.1-1%; high-MW for surface film, low-MW for dermal potential, check cationic compatibility.

Hydrolyzed Hyaluronic Acid

Low-MW humectant with superior penetration vs high-MW; 0.1-0.5% typical, hygroscopic, store dry to prevent clumping.

Sodium Hyaluronate

Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture

Polyglyceryl-10 Stearate

Polyglyceryl-10 stearate emulsifier; multi-source, mild, co-emulsifier

Salicylic Acid

Lipophilic BHA at 0.5-2%; exfoliant/sebum control, irritation/sensitization at high conc., photosensitivity (SPF needed), avoid sensitive/pregnant.
