Surfactants & Emulsifiers

Surfactants let cleansers lift dirt and oil from skin, while emulsifiers keep creams and lotions from separating. This category covers common members like glycerin-derived cleansers and emulsifying waxes. Browse 23 entries in this category.

Behentrimonium Chloride

A cationic conditioning ingredient that reduces hair static and improves combing in rinse-off and leave-on formulas.Waxy flakes and a white cream smear on terracotta

Ceteareth-20

An ethoxylated fatty-alcohol emulsifier: the number describes chemistry, not a 20% cream concentration.Comb and loose hair fibers beside an ivory conditioner swatch

Cetrimonium Chloride

A positively charged conditioning ingredient used for slip and static control, not evidence of hair regrowth.Translucent cleansing gel with coconut shell and sugar crystals

Coco-Glucoside

A nonionic sugar-based surfactant used to cleanse and foam, often in products positioned as mild.Thick white emulsion in a ceramic bowl with a small whisk

Glyceryl Stearate

A glycerin-and-stearic-acid ester that helps oil and water stay mixed while adding body and slip.Ink and paper collage of waxy flakes and a clear liquid vessel

Polyethylene Glycol (PEGs)

A family of polymers and derivatives with different sizes and uses; cosmetic PEGs, laxatives and rare PEG allergy need separate interpretation.Rough-cut coconut-oil soap bars with coconut and creamy lather

Sodium Cocoate

The sodium soap made from coconut-oil fatty acids, valued for cleansing and lather but capable of drying skin in high-pH formulas.White surfactant noodles, coconut shell, and soft cleanser foam

Sodium Cocoyl Isethionate

A coconut-fatty-acid-derived anionic surfactant valued for dense foam and generally milder cleansing than soap.Cream cleanser foam crossing cobalt and rust-red paper waves

Sodium Lauroyl Sarcosinate

An anionic surfactant used for cleansing and foam in facial washes, shampoos, and oral-care products.Risograph-style illustration of cleansing foam in a basin

Sodium Methyl Cocoyl Taurate

A taurate cleanser made with coconut-derived fatty acids; sulfate-free does not mean irritation-free.Ivory waxy flakes in a ceramic bowl beside a cream swatch on linen

Stearic Acid

A waxy fatty acid used to shape creams and cleansers, not an exfoliating acid or a proven standalone skin treatment.Powder bowl, thick clear gel and a small whisk

Xanthan Gum

A fermentation-derived thickener and stabilizer, not a live probiotic or a primary cleansing surfactant.

Surfactants & Emulsifiers

  1. 01Behentrimonium ChlorideA cationic conditioning ingredient that reduces hair static and improves combing in rinse-off and leave-on formulas.
  2. 02CarbomerThe gel-builder behind every clear serum — an invisible thickener with a confusing name and a clean safety record.
  3. 03Cellulose GumPlant cellulose made water-loving — the thickening fiber in ice cream, toothpaste, and the gut-permeability research debate.
  4. 04Ceteareth-20An ethoxylated fatty-alcohol emulsifier: the number describes chemistry, not a 20% cream concentration.
  5. 05Cetearyl AlcoholThe fatty-alcohol blend that gives creams their body — a 'drying alcohol' by name only, and an emollient in fact.
  6. 06Cetrimonium ChlorideA positively charged conditioning ingredient used for slip and static control, not evidence of hair regrowth.
  7. 07Cetyl AlcoholThe C16 fatty alcohol behind silky creams — a moisturizing thickener from coconut/palm, not a drying alcohol.
  8. 08Cocamidopropyl BetaineThe foam-boosting co-surfactant from coconut — gentle enough for baby shampoo, with an allergy reputation built on impurities.
  9. 09Coco-GlucosideA nonionic sugar-based surfactant used to cleanse and foam, often in products positioned as mild.
  10. 10Decyl GlucosideThe sugar-based cleanser — genuinely plant-derived, genuinely gentle, and the backbone of the 'clean' cleansing era.
  11. 11Glyceryl StearateA glycerin-and-stearic-acid ester that helps oil and water stay mixed while adding body and slip.
  12. 12Guar GumThe bean-derived thickener and fiber — a functional food ingredient with real cholesterol and blood-sugar data.
  13. 13Polyethylene Glycol (PEGs)A family of polymers and derivatives with different sizes and uses; cosmetic PEGs, laxatives and rare PEG allergy need separate interpretation.
  14. 14Polysorbate 20The gentler, water-loving polysorbate — a mild cleanser and solubilizer with less gut controversy than its big sibling.
  15. 15Polysorbate 80The emulsifier that makes oil and water mix — essential in vaccines, ice cream, and creams, controversial in some gut studies.
  16. 16Sodium CocoateThe sodium soap made from coconut-oil fatty acids, valued for cleansing and lather but capable of drying skin in high-pH formulas.
  17. 17Sodium Cocoyl IsethionateA coconut-fatty-acid-derived anionic surfactant valued for dense foam and generally milder cleansing than soap.
  18. 18Sodium Laureth SulfateSLS's gentler cousin — the ethoxylated cleanser behind most shampoos, milder by design and by decades of data.
  19. 19Sodium Lauroyl SarcosinateAn anionic surfactant used for cleansing and foam in facial washes, shampoos, and oral-care products.
  20. 20Sodium Lauryl Sulfate (SLS)The foaming workhorse of shampoo and toothpaste — an effective, safe-at-rinse-off cleanser with an irritation reputation to manage.
  21. 21Sodium Methyl Cocoyl TaurateA taurate cleanser made with coconut-derived fatty acids; sulfate-free does not mean irritation-free.
  22. 22Stearic AcidA waxy fatty acid used to shape creams and cleansers, not an exfoliating acid or a proven standalone skin treatment.
  23. 23Xanthan GumA fermentation-derived thickener and stabilizer, not a live probiotic or a primary cleansing surfactant.
