Glycerin

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

Butylene Glycol

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

Acetamide Mea

Not decoded yet

Hexylene Glycol

Polyol solvent and humectant with penetration enhancement; limit concentration to avoid irritation, no specific allergen tag

Niacinamide

Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity

Scutellaria Baicalensis Root Extract

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

Propanediol

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

Arginine

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

Aloe Barbadensis Leaf Extract

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

Glycine Soja Germ Extract

Soy germ extract with proteins and lipids for hydration; soy is a common allergen, labeling required.

Triticum Vulgare Germ Extract

Wheat germ extract, nutrient-rich; contains gluten, test for sensitivity.

Cleome Gynandra Leaf Extract

Not decoded yet

Chondrus Crispus Extract

Carrageenan for thickening and moisturizing; seaweed-based, pH-sensitive

Crambe Abyssinica Seed Oil

Crambe abyssinica seed oil for hair/skin; oleic-rich, high oleic ratio may be comedogenic

Geranium Maculatum Extract

Geranium extract for toning; botanical actives, watch batch variation and potential allergenicity.

Taraxacum Officinale Leaf Extract

Taraxacum leaf extract for soothing; plant extract may contain particulates, filtration needed.

Sambucus Nigra Flower Extract

Plant extract for soothing and toning; high levels of crude extracts may sensitize.

Hibiscus Sabdariffa Flower Extract

Roselle flower extract rich in anthocyanins, used for skin conditioning and antioxidant support

Calendula Officinalis Flower Extract

Calendula extract for soothing and repair; aqueous systems, monitor extract residues.

Fructose

Strong humectant; high levels can increase viscosity and hygroscopicity.

Retinyl Palmitate

Vitamin A ester for skin conditioning; light-sensitive, requires protection, avoid in pregnancy.

Tocopheryl Acetate

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

Ascorbyl Palmitate

Ascorbyl palmitate, lipophilic Vit C ester, antioxidant; oxidizes, needs light/air protection.

Hydrolyzed Cottonseed Extract

Not decoded yet

Glucose

Low-MW humectant and buffer; high hygroscopicity requires careful preservation and humidity control.

Inositol

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

Sucrose

Sucrose, water-soluble thickener and humectant; high levels prone to hygroscopy.

Trehalose

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

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Oryza Sativa Extract

Physical exfoliant and absorbent powder for cleansing and texture; abrasive particles, avoid high frequency on sensitive or compromised skin

Glycine Max Seed Extract

Soybean extract for hair and skin conditioning and protection; contains plant proteins.

Daucus Carota Sativa Root Extract

Carrot root extract with carotenoids; skin conditioning, low photosensitivity, may stain.

Chenopodium Quinoa Seed Extract

Quinoa seed extract, protein/polypeptide conditioner; water-soluble, check charge interactions with actives.

Panax Ginseng Root Extract

Botanical extract for skin and hair conditioning; activity and irritation risk vary by source/purity, patch test for sensitive skin

Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light

PPG-26-Buteth-26

Not decoded yet

PEG-40 Hydrogenated Castor Oil

Solubilizer and emulsifier for oil-soluble ingredients; high concentrations may cause contact dermatitis in sensitive skin.

Carbomer

Gelling thickener requiring neutralization; watch out for ion compatibility

Aminomethyl Propanol

pH buffer at 0.1–1%; irritating at high levels, avoid direct mixing with strong acids/bases

Ethylhexylglycerin

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

Cellulose

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

Mannitol

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

Lactose

Low-irritant humectant and skin conditioner, common in gentle formulations.

Lactic Acid

AHA pH adjuster at 0.5-5%; exfoliation/humectancy, mild at low conc., irritating at high, avoid conflict with alkaline preservatives.

Hydroxypropyl Methylcellulose

High polymer for thickening and film formation; water-soluble, used in physical sunscreens or gels, tacky at high levels

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Gluconolactone

Multifunctional agent for chelation and permeation; acidic, may irritate at high levels, buffer recommended.

Sodium Hyaluronate

Sodium Sulfite

Sulfite antioxidant to prevent oxidation; sulfites are known allergens and must be strictly declared on labels.

Sodium Citrate

Sodium citrate for buffering and chelating; adjust pH, careful with strong acid reactions.

Aluminum Hydroxide

Calcium Gluconate

Chelator and conditioner, improves stability; water-soluble calcium source

Phenoxyethanol

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

Disodium EDTA

Fragrance/Parfum

Fragrance mixture for odor; complex composition with potential allergens, use with caution in sensitive or children's products.
