Ingredients explained

Avobenzone

Organic UV filter for UVB and part of UVA-I; poor photostability, used in synergy with other filters.

Homosalate

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

Octisalate

Octyloleate, ester solvent and emollient; used in sunscreens or diluting oils, light texture

Octocrylene

UV-B absorber and photostabilizer; has concentration limits, consider potential coral toxicity and allergenicity for specific groups.

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

Butylene Glycol

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

Octyldodecyl Neopentanoate

Ester emollient; light oil feel; low irrit, low comed, good for fresh systems

Argania Spinosa Kernel Oil

Jojoba oil rich in unsaturated fats; good penetration, non-comedogenic, prone to oxidation requiring antioxidants

Tocopheryl Acetate

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

Glyceryl Stearate

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

Styrene/Acrylates Copolymer

Film former and opacifier for powder makeup; some batches contain sensitizing monomers.

Dimethicone

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

Yeast Extract

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

PEG-100 Stearate

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

Cetyl Alcohol

Cetyl alcohol for emulsification/thickening; high concentration >10% may irritate.

Stearic Acid

Fatty acid emulsifier, white waxy solid; adds slip feel

Phenoxyethanol

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

Saccharide Isomerate

Novel polyol humectant with skin feel improvement; high hydration, suitable for lightweight formulas.

Persea Gratissima Oil

Avocado oil rich in fatty acids and vitamin E; occlusive moisturizer, use with caution on oily skin.

Diethylhexyl Syringylidenemalonate

New UV filter (UVA/UVB); EU limits 2.8%/1.4%, potential sensitizer, stability required

Pentylene Glycol

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

Hydrolyzed Wheat Protein/PVP Crosspolymer

Film former and hair conditioner complex for styling and protection; wheat protein may trigger allergies.

Sodium Hyaluronate

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

Sclerotium Gum

Non-ionic gum for gels; neutral pH, requires dissolution via heating or fine milling

Bisabolol

Soothing and anti-inflammatory agent, 0.01–0.1%; low irritation, good for sensitive skin.

Octyldodecanol

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

Sodium Phytate

Chelating agent stabilizes metal ions to prevent oxidative degradation; also used in oral care, high safety profile.

Caprylic/Capric Triglyceride

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

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Ethylhexylglycerin

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

Disodium EDTA

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

Ceramide NP

Ceramide N3 for barrier repair; lipophilic, needs oil phase or emulsion, avoid high standalone use.

Citric Acid

Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH

Sodium Citrate

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

Ammonium Hydroxide

Strong alkaline pH adjuster; use in low concentrations to neutralize acids, avoid direct mixing with strong acids.

Ceteareth-25

Not decoded yet

Glycerin

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

Behenic Acid

Behenic acid, emulsifier and thickener; high comedogenic rating, limit use on acne-prone skin.

Cholesterol

Cholesterol; barrier repair lipid mimicking stratum corneum; often blended with ceramides, plant or fermentation source.

Ceramide NS

Ceramide NS for barrier repair; gentle and suitable for sensitive or dry skin.

Ceramide EOS

Barrier-repairing ceramide, 0.1–1%; optimal with hydrated lipids, suitable for dry skin

Ceramide EOP

Ceramide EOP, repairs skin barrier lipids; often blended with cholesterol and fatty acids.

Ceramide AP

Ceramide analog for barrier repair; best results when combined with cholesterol and free fatty acids

Caprooyl Phytosphingosine

Plant-derived biomimetic lipid for hair and skin conditioning.

Caprooyl Sphingosine

Biomimetic lipid for hair and skin conditioning; often formulated with other lipids.

Tocopherol

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

Ascorbyl Palmitate

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