Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Dimethicone

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

Propanediol

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

Glycerin

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

1,2-Hexanediol

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

Sodium Acrylates Copolymer

Water-soluble film former for styling and thickening; check residual acryloyl chloride for sensitive skin.

Dimethicone Crosspolymer

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

Butylene Glycol

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

Pseudoalteromonas Ferment Extract

Microbial ferment for humectancy and skin conditioning; gentle.

Glycereth-26

Glycereth-26, humectant/viscosity modifier at 1–5%; non-ionic water-soluble, boosts stability and feel.

Lecithin

Phospholipid emulsifier at 1-5%; biocompatible, moisturizing/antioxidant, prone to oxidation (add TBHQ), mild for sensitive skin.

Maltodextrin

High-MW multifunctional excipient for thickening, binding, and emulsion stability; inert, non-penetrating conditioning.

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Pentylene Glycol

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

Lens Esculenta Seed Extract

Lentil seed extract with proteins; provides skin protection and conditioning

Parfum

Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.

Disodium EDTA

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

Hydrolyzed Hyaluronic Acid

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

Sodium Hyaluronate

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

Xanthan Gum

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

Citric Acid

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

Biosaccharide Gum-1

Biosaccharide Gum-1, fermented colloid for hydration and soothing, low comedogenic.

Carbomer

Gelling thickener requiring neutralization; watch out for ion compatibility

Polysorbate 20

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

Sodium Lactate

Sodium lactate for moisturizing and exfoliation; pH buffering agent

Sodium Salicylate

Preservative (V/3 limit) and keratolytic aid; caution for sensitive skin and pregnancy.

Salicylic Acid

Lipophilic BHA at 0.5-2%; exfoliant/sebum control, irritation/sensitization at high conc., photosensitivity (SPF needed), avoid sensitive/pregnant.

Palmitoyl Tripeptide-1

Palmitoyl Tripeptide-1 for repair; requires lipid carrier, unstable in aqueous phase

Palmitoyl Tetrapeptide-7

Palmitoyl Tetrapeptide-7 boosts collagen; use 0.1–1%, formulate with lipid carriers
