Ingredients explained

Aqua/Water/Eau

Water as solvent/base; main ingredient, microbial control needed, paired with preservatives.

Glycerin

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

Propanediol

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

Alcohol

Ethanol for solubility/drying at 5-15%; high conc. is drying/irritating, avoid lip/eye, low residue, balance with humectants.

Cyclopentasiloxane

Cyclopentasiloxane for emollient/solvent; volatile silicone, smooth feel, check VOC regulations.

Squalane

Emollient from plants or synthetic; light texture

Camellia Sinensis Leaf Extract

Green tea extract for antioxidant/astringent; contains caffeine, possible irritation in sensitive skin.

Inositol

Humectant at 0.5–2%; gentle moisturizing, suitable for sensitive skin

Algae Extract

Algae extract with humectant and conditioning effects; may contain natural fragrant components.

Sericin

Animal-derived silk protein, used for anti-static and hair/skin conditioning; provides smoothness and repair.

Glycyrrhiza Glabra Root Extract

Liquorice root extract for soothing and brightening; batch variability, watch polyphenol interactions

Oryza Sativa Germ Oil

Rice bran oil, moisturizing conditioning; 1–5% typical, low irritation, low comedogenicity

Hydrogenated Lecithin

Emulsifier from lecithin; stable, used in powder emulsions

Ziziphus Jujuba Fruit Extract

Natural antioxidant extract; polyphenols, prone to browning.

Scutellaria Baicalensis Root Extract

Scutellaria root extract with baicalin for antioxidant and soothing effects; also provides astringent and humectant properties.

Isocetyl Stearate

Isocetyl stearate; emollient, low comedogenic risk

Polyglyceryl-2 Triisostearate

Mild non-ionic emulsifier for creams; oily feel, suitable for dry skin, control usage for oily skin

Polyglyceryl-10 Isostearate

Gentle emollient and emulsifier; improves texture, low comedogenic risk

Ethylhexylglycerin

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

Glyceryl Stearate

Emulsifier at 1-3%; may require acid to prevent saponification

Behenyl Alcohol

Fat alcohol emulsifier/thickener at 1-3%; low comedogenic risk, check solubility in strong acid/base systems, add antioxidants.

Arginine

Arginine for moisturizing/conditioning; amino acid, high biocompatibility, often used in blends.

Carbomer

Gelling thickener requiring neutralization; watch out for ion compatibility

Xanthan Gum

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

Biosaccharide Gum-1

Biosaccharide Gum-1, fermented colloid for hydration and soothing, low comedogenic.

Sodium Hyaluronate

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

Cetearyl Alcohol

Fatty alcohol emulsifier at 1-5%; non-ionic surfactant

Sodium Lauroyl Lactylate

Mild emulsifier at 1–5%; suitable for sensitive skin, mind cationic surfactant compatibility

Sorbitan Stearate

Non-ionic emulsifier for O/W systems; hydrophobic, requires co-emulsifiers, inert at high purity

Caprylic/Capric Triglyceride

Light occlusive and solvent at 1–10%; non-greasy feel, suitable for oily and combination skin

Parfum/ Fragrance

Fragrance ingredient providing product scent; may contain 26 allergens, labeling required
