Formulation view Soap base combined with amino and amphoteric surfactants, including PEG emulsifiers. Features salicylic acid, botanicals, and menthol derivatives. Ideal for mixed/oily skin seeking deep cleansing and cooling sensation. Formulator note: PEG emulsifiers require monitoring for formaldehyde releasers; salicylic acid and menthol provide instant cooling and exfoliation, which may irritate sensitive skin, so short-term use is advised.

Ingredients explained

Water

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

Stearic Acid

Fatty acid emulsifier, white waxy solid; adds slip feel

Glycerine

Workhorse humectant at 3-10%; tacky at high levels, pair with occlusives, low irritancy.

Myristic Acid

Saturated fatty acid, saponification feedstock; insoluble alone, pairs with stearic acid.

Lauric Acid

Lauric acid for cleansing and emulsification; high comedogenic rating, recommend limiting to 1-2% or combining with other acids.

Potassium Hydroxide

Strong alkali pH adjuster, trace usage (<0.1%); corrosive, must be neutralized.

PEG-8

Not decoded yet

PEG-60 Glyceryl Isostearate

Non-ionic solubilizer/emulsifier; high HLB, often paired with anionics, may increase penetration.

Potassium Cocoyl Glycinate

Amino acid surfactant for mild cleansing; fine foam, low irritation, suitable for sensitive and baby products

Cocamidopropyl Betaine

Cocamidopropyl betaine; zwitterionic co-surfactant reducing irritation and boosting foam, common in mild cleansers.

Glyceryl Stearate

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

PEG-100 Stearate

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

Polysorbate 20

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

Sorbitan Olivate

O/W emulsifier, HLB ~15, requires ionic co-surfactant, potential sensitizer.

Polyquaternium-7

Not decoded yet

Propanediol

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

Fragrance

Fragrance; concentration must control allergen risk, label specific components

Sodium Chloride

Salt for gel viscosity control; used as precipitant in soaps

Sodium Methyl Cocoyl Taurate

Amino acid based mild surfactant, soft lather; cleaning power increases with salt but may dry out.

Chlorphenesin

Phenolic antimicrobial; strict EU limits apply, potential allergen, careful dosing required for leave-on products.

Salicylic Acid

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

Methyl Diisopropyl Propionamide

Fragrance ingredient providing herbal or fruity notes; used in low doses; potential allergen, compliance labeling required.

Caprylyl Glycol

Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol

Disodium EDTA

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

Tocopheryl Acetate

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

Sodium Hyaluronate

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

Centella Asiatica Extract

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

Ficus Carica Fruit Extract

Fig fruit extract, humectant with polysaccharides and enzymes for skin moisturizing

Acmella Oleracea Extract

Eyebright extract, used for calming and anti-oxidant purposes; often included in eye-care formulas.

Amaranthus caudatus seed extract, skin conditioner; plant extract, focus on extract concentration and allergen screening.

Ulmus Davidiana Root Extract

Plant extract for basic skin conditioning; low usage, ensure raw material consistency

Undaria Pinnatifida Extract

Kelp extract; algal polysaccharides. Hydrating and film-forming, verify compatibility in high-salt formulas.

Menthyl Lactate

Menthyl lactate, cooling and fragrance agent, provides mild menthol sensation for refreshing

Butylene Glycol

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

Ethyl Menthane Carboxamide

Cooling agent; immediate tingle, recommend 0.1-0.3% usage

Ethylhexylglycerin

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

1,2-Hexanediol

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

Aloe Barbadensis Leaf Extract

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

Limonene
