Ingredients explained

Water

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

Propanediol

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

Tetrahexyldecyl Ascorbate

Lipophilic Vitamin C derivative, antioxidant and brightening; more stable than VC, oil-soluble, must pair with oil phase

C9-12 Alkane

C9-12 alkanes; solvent and emollient. Lightweight feel, verify source and refining history.

Glycerin

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

Tocopheryl Acetate

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

Behenyl Alcohol

Fat alcohol emulsifier/thickener at 1-3%; low comedogenic risk, check solubility in strong acid/base systems, add antioxidants.

Stearic Acid

Fatty acid emulsifier, white waxy solid; adds slip feel

Ferulic Acid

Antioxidant, often combined with vitamin C and E; 0.5-2%, photolabile

Cetyl palmitate

Waxy ester increasing viscosity and providing heavy feel; used as emulsifier carrier, low comedogenicity, strong occlusion.

Polyglyceryl-2 stearate

Polyglyceryl ester emulsifier; mild, non-ionic, suitable for O/W emulsions with good stability.

Oleic Acid

Oleic acid for emolliency/emulsification; high levels may increase skin penetration

Soy acid

Not decoded yet

Polymethylsilsesquioxane

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

Sodium Hyaluronate

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

Hydrolyzed collagen

Hydrolyzed protein for film-forming and moisture; molecular weight limits penetration, check source for shellfish allergies

Hydrolyzed elastin

Hydrolyzed elastin, moisturizer; MW determines penetration, large MW surface conditioning.

Diamond Powder

Diamond powder as abrasive; high hardness, check particle uniformity

Curcuma Longa Root Extract

Turmeric root extract, contains curcumin, colorant/antioxidant; high doses may sensitize.

Zingiber Officinale Root Extract

Root extract for scent and toning; may irritate compromised skin.

Tocopherol

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

Haematococcus Pluvialis Extract

Haematococcus pluvialis extract rich in astaxanthin; potent antioxidant; used in anti-aging and photoprotection formulas.

Glyceryl Stearate

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

Gluconolactone

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

Stearyl Alcohol

Stearic alcohol; fatty alcohol for emulsion thickening/structure, often blended with soaps, moderate comedogenicity.

Polyglyceryl-6 distearate

Non-ionic emulsifier; mild, PEG-free, good compatibility for cream systems.

Carbomer

Gelling thickener requiring neutralization; watch out for ion compatibility

Coco-caprylate/Caprate

Lightweight mid-chain ester, quick spreading, suitable for oily skin, non-comedogenic.

Sodium PCA

Sodium PCA, NMF component, 1-10% humectant; salty/tacky at high levels.

Disodium EDTA

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

Vegetable Oil

Generic vegetable oils for hair/skin conditioning; specify oil type and oxidative stability.

Jojoba esters

Jojoba esters, light emollient ester, low comedogenic; sebum-like, excellent spreadability.

Sodium stearoyl lactylate

Mild emulsifier/stabilizer for O/W; control usage to prevent viscosity issues

Cetyl Alcohol

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

Butyrospermum Parkii Butter

Shea butter for occlusive moisturizing; high melt point, rich texture, caution for oily skin.

Histidine HCL

Amino acid salt for pH buffering and hair conditioning; gentle buffering system, potential sensitization at high concentrations.

Sodium Lactate

Sodium lactate for moisturizing and exfoliation; pH buffering agent

Xanthan Gum

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

Polyglyceryl-3 beeswax

Beeswax-derived emulsifier, mild and biodegradable; offers emollience for sensitive formulations

Sodium carboxymethyl beta-glucan

Modified glucan for thickening and cleansing aid; low irritation, suitable for most formulas

Calcium gluconate

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

Ceramide NP

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

Glycine Soja Sterols

Plant-derived emollient and conditioner; high purity and suitable for sensitive skin

Sucrose stearate

Succrose ester emulsifier/emolient with cleansing properties; HLB determines emulsion type.

Carnosine

Dipeptide skin conditioner with antioxidant and buffering properties; used in synergy with other actives.

Lactic Acid

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

Lecithin

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

Polyglyceryl-10 laurate

Mild non-ionic emulsifier for O/W systems; cetyl ester structure may irritate sensitive skin, use at 0.5-3%.

Wheat amino acids

Wheat amino acids for hair/skin; contains gluten, allergy caution

Ethylhexylglycerin

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

Mica

Mineral colorant for pearlescence; heavy metal screening required

EDTA

Chelating agent for stability; use metal salts, keep concentration low (<0.1%) to maintain pH.

Sodium Hydroxide

Strong base neutralizer for pH adjustment; handle with extreme care

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Phenoxyethanol

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