Ingredients explained

Water

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

Ethylhexyl Methoxycinnamate

UVA absorber used with other filters; poor water stability and photolability, requires light stabilizers, max concentration typically 10%.

Homosalate

UVB sunscreen agent, often combined with others; stable but migratory; ensure regulatory compliance.

Ethylhexyl Salicylate

Ethylhexyl salicylate, UVB absorber; volatile, requires combination with UVA filters for broad spectrum.

Diethylamino Hydroxybenzoyl Hexyl Benzoate

Novel UVB absorber at 0.2-1.5%; narrow band, requires combination, high photostability, verify regional limits, low irritation.

Propanediol

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

Dimethicone Crosspolymer

Crosslinked silicone polymer providing silkiness and viscosity control; for hair and skin; inert but hard to biodegrade.

Pentylene Glycol

Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin

Salvia Hispanica Seed Extract

Plant extract with mucilage and saponins; acts as skin emollient and conditioning agent.

Centella Asiatica Extract

Centella asiatica extract for soothing/repair; low irritation, common in sensitive skin products.

Houttuynia Cordata Extract

Houttuynia cordata extract for anti-inflammatory and soothing effects; contains volatile oils, patch test recommended for sensitive skin.

Ammonium Acryloyldimethyl Taurate/VP Copolymer

Cationic polymer enhancing conditioning agent deposition on hair; improves detangling and antistatic properties.

Fructooligosaccharides

Prebiotic polysaccharide for hydration/skin conditioning; high levels may feel sticky

Saccharide Hydrolysate

Saccharide hydrolysate, strong humectant with hygroscopic properties; suitable for various dosage forms.

Acrylates/C10-30 Alkyl Acrylate Crosspolymer

Crosspolymer for thickening/film; needs neutralization to pH 7-8 to hydrate, check ion strength.

Ethylhexylglycerin

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

Triethanolamine

Triethanolamine for buffering; restricted, limit concentration to avoid high pH and irritation

Pullulan

Microbial polysaccharide for film forming and thickening; water-soluble film former used in capsules or moisturizing films.

Octyldodecanol

Light emollient/emulsifier at 1-5%; low comedogenic, non-greasy feel, broadly compatible, sensitive-skin friendly.

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

Anthemis Nobilis Flower Extract

Chamomile extract used for soothing; check for potential sensitizing allergens.

Echium Plantagineum Seed Oil

Linoleic-rich seed oil; high oxidation risk, requires antioxidants and light protection to maintain stability

Helianthus Annuus Seed Oil

Sunflower seed oil for emollient/occlusive; high linoleic acid, low comedogenicity.

Persea Gratissima Fruit Extract

Avocado extract for emollience/hydration; oily base, may clog acne-prone skin at high levels.

Calendula Officinalis Flower Extract

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

Cardiospermum Halicacabum Flower/Leaf/Vine Extract

Plant-derived skin-conditioning extract; used at low levels, stability must be verified.

Dimethicone

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

Xanthan Gum

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

Polyglyceryl-3 Methylglucose Distearate

Non-ionic emulsifier at 1–3%; mild, easily combined with other surfactants.

Polysorbate 20

Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.

Polyacrylate Crosspolymer-6

Water-soluble thickener; requires neutralizer, performs best at pH 5–7

Titanium Dioxide

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

C12-15 Alkyl Benzoate

C12-15 alkyl benzoate; emollient, emulsifier, and antistatic; aids stability and smoothness, moderate low comedogenicity.

Tocopherol

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

Glyceryl Stearate

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

Aloe Barbadensis Leaf Extract

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

PEG-100 Stearate

Non-ionic emulsifier, requires ionics for stability; check PEG for formaldehyde.

Aluminum Stearate

Aluminum stearate used as anticaking, emulsion stabilizer, and viscosity controller; restricted to IV/150 uses, avoid direct contact with acids.

Oleth-10

Not decoded yet

Polyhydroxystearic Acid

Emulsifier and stabilizer at 1–3%; non-ionic, prone to hydrolysis.

Alumina

Alumina, inorganic abrasive/thickener; nano-grade requires inhalation risk assessment.

Isodeceth-6

Not decoded yet

T-Butyl Alcohol

Fast-evaporating solvent; sharp odor and potential irritation at high levels, limit usage

Simethicone

Silicone antifoam and conditioner; non-allergenic, smooth feel

Phenoxyethanol

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

Fragrance

Fragrance; concentration must control allergen risk, label specific components
