Ingredients explained

Water

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

Methyl Trimethicone

Methyl trimethicone, light volatile silicone; non-comedogenic, good powder compatibility.

Butylene Glycol

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

Dimethicone

Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin

Biosaccharide Gum–1

Not decoded yet

Bis-PEG-18 Methyl Ether Dimethyl Silane

Silicone modifier for smoothness; contains PEG, used for foam and cleansing, manage PEG residuals

Glycerin

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

PEG-60 Hydrogenated Castor Oil

Non-ionic emulsifier and solubilizer at 1–5%; contains PEG, check acid compatibility and sensitive skin irritation

Methyl Gluceth-20

Not decoded yet

Silica

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

Tocopheryl Acetate

Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light

Algae Extract

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

Sodium Hyaluronate

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

Yeast Extract

Yeast extract for skin care and protection; common, low allergy risk

Citrus Reticulata Peel Extract

Citrus peel extract containing photosensitizing compounds; handle with care to avoid photo-reactions, subject to EU restrictions.

Aloe Barbadensis Leaf Extract

Aloe vera leaf extract for soothing and humectant; monitor polysaccharide level and endotoxins

Hordeum Vulgare Extract

Barley extract with beta-glucans/amino acids, moisturizing/soothing at 1–5%; watch for microbial growth.

Polygonum Cuspidatum Root Extract

Polygonum cuspidatum root extract, source of resveratrol antioxidant; water or alcohol soluble, check color shift with iron ions

Cucumis Sativus Fruit Extract

Botanical extract for conditioning; note extraction impact on active retention

Vitis Vinifera Seed Extract

Grape seed extract with OPCs; potent antioxidant; used for skin protection and UV support; needs stabilizers.

Rosmarinus Officinalis Extract

Rosemary extract; antimicrobial; photo-toxic and allergen risks.

Selaginella Tamariscina Extract

Humulus Lupulus Extract

Hops extract: antimicrobial/antiperspirant/conditioner/fragrance; test on sensitive skin.

Padina Pavonica Thallus Extract

Not decoded yet

Astrocaryum Murumuru Seed Butter

Plant oil for emollience and conditioning; high lipid content, pair with emulsifiers

Helianthus Annuus Seedcake

Sunflower seed cake; physical exfoliant and bulking agent. Coarse texture, use caution for sensitive skin, requires homogenization.

Cocos Nucifera Oil

Occlusive moisturizing oil at 1–10%; highly comedogenic, use with caution for oily skin.

Punica Granatum Fruit Juice

Pomegranate juice; rich in polyphenols for fragrance and skin conditioning. Low pH requires neutralization; prone to browning, use antioxidants and dark packaging.

Caffeine

Active ingredient, 0.1–2%; promotes circulation, irritation risk at high concentration.

Trehalose

Trehalose; mild humectant and stabilizer for proteins/actives; hygroscopic, light skin feel.

Propylene Glycol Dicaprate

Lightweight emollient ester; replaces mineral oils with non-greasy feel; good for oily skin systems

Dipotassium Glycyrrhizate

Dipotassium glycyrrhizinate for moisturizing/soothing; inhibits 5-LOX, water-soluble, for sensitive skin.

Sodium PCA

Sodium PCA, NMF component, 1-10% humectant; salty/tacky at high levels.

Phytantriol

Botanical-derived humectant from phytane derivatives; enhances skin water retention

Ethylhexyl Palmitate

Synthetic ester emollient with light skin feel; small molecule, slightly comedogenic, use cautiously for acne-prone skin, often blended with other oils.

Acetyl Carnitine Hcl

Not decoded yet

Caprylyl Glycol

Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol

Carbomer

Gelling thickener requiring neutralization; watch out for ion compatibility

Tromethamine

pH adjuster, alkaline; precise dosing required

Polymethylsilsesquioxane

Silicone polymer for emolliency, matte effect, and suspension; used in foundations or powder suspensions, typical usage 1-5%, smooth skin feel.

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

Linolenic Acid

Omega-6 fatty acid for barrier repair; prone to oxidation, needs antioxidants and low light exposure

Linoleic Acid

Essential fatty acid for barrier repair and hydration; oxidizes easily, high levels may be comedogenic

Disodium EDTA

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

Nordihydroguaiaretic Acid

Lipid peroxide scavenger, BHT alternative; low dose (0.1–0.25%), check photostability

Ethylbisiminomethylguaiacol Manganese Chloride

Manganese chelator/antioxidant stabilizer; synergizes with Vit E; avoid iron contact

Phenoxyethanol

Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
