Ingredients explained

Water/Aqua/Eau

Primary aqueous solvent and carrier; no specific incompatibilities, focus on microbial stability.

Glycerin

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

Isododecane

Synthetic hydrocarbon solvent providing dry, silky skin feel; high volatility, non-comedogenic, common in sunscreens and foundations, usage 5-30%.

Hydrogenated Polydecene

Hydrogenated polydecene, light mineral oil alternative, low comedogenic; silky, non-greasy.

Caprylic/Capric Triglyceride

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

Butylene Glycol Dicaprylate/Dicaprate

Light diester emollient, light and non-greasy; often used as solvent; oxidizes easily, needs antioxidants.

Talc

Inorganic mineral powder for texture and oil absorption; must be asbestos-free; fineness affects skin feel and safety, avoid inhalation.

Alcohol Denat

Denatured ethanol; solvent, penetration enhancer, and quick-dry agent; high % may compromise barrier in dry skin.

Hydrogenated Poly

Hydrogenated poly C6-14 olefins, saturated oil; occlusive, low permeability

Hydrogenated Polyisobutene

Hydrogenated polyisobutene; petroleum-derived lubricant forming breathable film; high purity, low irritation/comedogenicity.

Butylene Glycol

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

Dipropylene Glycol

Solvent for essential oils; better humectancy than PEG

Nylon-12

Not decoded yet

Polyglyceryl-4 Diisostearate/Polyhydroxystearate/Sebacate

Composite emulsifier for stable O/W systems, provides mild cleansing.

Vinyl Dimethicone/Methicone Silsesquioxane Crosspolymer

Rheology-modifying silicone polymer for suspension and feel; requires silicone-compatible system

Magnesium Sulfate

Bulk agent at 0.1–1%; highly water-soluble, avoid high local concentration.

Alumina

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

Silica

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

Dimethicone

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

Dimethicone/Vinyl Dimethicone Crosspolymer

Crosslinked silicone thickener at 0.5-2%; silky/matte feel, non-comedogenic, partial oil phase incompatibility, use co-solvent/pre-emulsification.

Polyglyceryl-3 Oleate

Gentle emulsifier, low irritancy; suitable for sensitive skin formulas, requires appropriate emulsification temperature.

Sorbitan Isostearate

Non-ionic emulsifier (low HLB); typically used in blends, low comedogenicity, soft skin feel.

Stearalkonium Hectorite

Inorganic clay gellant with silky feel; must disperse well, high local dose can irritate.

Diisostearoyl Polyglyceryl-3 Dimer Dilinoleate

Modified ester oil for silkiness/emollience; biocompatible, can act as a solvent.

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Dimethicone Crosspolymer

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

Propylene Carbonate

Inert solvent and viscosity modifier; often used as penetration enhancer, mild at low levels

Polymethylsilsesquioxane

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

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Tocopheryl Acetate

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

Triethoxycaprylylsilane

Silane coupling agent at 0.1-0.5%; enhances inorganic filler adhesion, trace use, low toxicity, avoid direct contact with aqueous systems.

Niacinamide

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

Sargassum Pacificum Thallus Extract

Not decoded yet

Tocopherol

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

1,2-Hexanediol

Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives

Hydrolyzed Extensin

Hydrolyzed protein (grape source) for moisture and conditioning; low MW, low allergy risk.

Glycine Soja Oil

Soybean oil emollient; prone to oxidation, needs antioxidants; suitable for dry skin

Phenoxyethanol

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

Macrocystis Pyrifera Extract

Giant kelp extract; moisturizing polysaccharides; ocean theme, check for marine allergies.

Sodium Hyaluronate

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

Pancratium Maritimum Extract

Seaholly extract; provides natural moisturizing polysaccharides; mild and highly hydrating at low usage levels.

Hydrolyzed Ginseng Saponins

Used for anti-aging and skin conditioning; hydrolyzed form is stable, no known allergenic risks.

Hydroxypropyltrimonium Hyaluronate

Cationic hyaluronic acid, 0.1–1%; water-soluble thickener and conditioning agent.

Hydrolyzed Hyaluronic Acid

Low-MW humectant with superior penetration vs high-MW; 0.1-0.5% typical, hygroscopic, store dry to prevent clumping.

Sodium Acetylated Hyaluronate

Acetylated HA; modified for hydrophobicity, improved penetration and non-tacky feel compared to standard HA.

Hyaluronic Acid

High-water-binding humectant at 0.1-1%; high-MW for surface film, low-MW for dermal potential, check cationic compatibility.

Hydrolyzed Sodium Hyaluronate

Low-molecular-weight hyaluronic acid derivative with better penetration and strong hydration; different molecular weights provide hydration at various depths, typical concentration 0.1-1%.

Sodium Hyaluronate Crosspolymer

Crosslinked high-MW HA; forms surface hydrogel for long-lasting hydration, minimal penetration, physical film-forming.

Potassium Hyaluronate

Hyaluronic salt, excellent humectant; efficacy varies with MW, best with occlusive base

Titanium Dioxide

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

Iron Oxides (Ci 77491

Ci 77492

Iron oxide red; stable inorganic pigment, non-toxic; ensure dispersion to prevent sedimentation.
