Surfactant
Sorbitan Stearate

A nonionic emulsifier (the mono-stearate ester of sorbitan) with a low HLB, used to form or stabilize water-in-oil emulsions in creams and lotions.

emulsifier
Creates stable water-in-oil emulsionsImproves product texture and spreadability
Surfactant
Sorbitan Tristearate

A nonionic triester of sorbitan and stearic acid (three stearate groups) with a low HLB, used to form and stabilize water-in-oil emulsions in creams and lotions.

Surfactant
Steareth-10

A PEG-10 ether of stearyl alcohol used as an emulsifier and surfactant in creams and lotions.

emulsifiersurfactant
Stabilizes oil-in-water emulsionsImproves texture and spreadability of creams and lotions
May contain trace 1,4-dioxane as a manufacturing by-product of ethoxylation; purification steps can reduce levels (FDA recommends ≤10,000 ppb in cosmetics)
Surfactant
Steareth-20

A PEG-20 ether of stearyl alcohol used as an emulsifier in a wide range of cosmetic emulsions.

May contain trace 1,4-dioxane as a manufacturing by-product of ethoxylation; purification steps can reduce levels (FDA recommends ≤10,000 ppb in cosmetics)
Surfactant
Steareth-21

A PEG-21 ether of stearyl alcohol functioning as an emulsifier in cosmetic creams and lotions.

emulsifiersurfactant
Stabilizes oil-in-water emulsions with slightly higher HLB than Steareth-20Improves consistency and skin feel of emulsions
May contain trace 1,4-dioxane as a manufacturing by-product of ethoxylation; purification steps can reduce levels (FDA recommends ≤10,000 ppb in cosmetics)
Surfactant
Stearoyl Glutamic Acid

A fatty acid-amino acid conjugate (stearic acid + glutamic acid) used as a mild emulsifier and skin-conditioning agent, particularly common in Japanese sunscreen formulations.

emulsifierskin-conditioning
Acts as an amino acid-derived emulsifier with good skin compatibilityProvides a smooth, non-greasy skin feel
Surfactant
Steartrimonium Bromide

A quaternary ammonium compound used as an antistatic agent and mild surfactant, also providing some antimicrobial activity.

antistaticsurfactantpreservative-booster
Provides antistatic conditioning to skin surfaceMild antimicrobial supporting preservation
Quaternary ammonium compound; may be irritating at high concentrations
Surfactant
Sucrose Laurate

A sucrose ester of lauric acid used as a mild, plant-derived emulsifier and surfactant in cleansers and emulsions.

emulsifiersurfactantskin-conditioning
Mild, naturally-derived sugar ester surfactant suitable for sensitive skinBiodegradable and plant-derived
Surfactant
Sucrose Stearate

A sugar ester of stearic acid that acts as a mild nonionic emulsifier for oil-in-water systems, with a high HLB and skin-conditioning properties.

emulsifieremollient
Gentle, plant-derived oil-in-water emulsificationLeaves a soft, conditioning finish on skinFree of ethoxylated compounds — suitable for natural formulations
Surfactant
Trideceth-10

An ethoxylated C13 fatty alcohol with 10 ethylene oxide units, used as a mild nonionic emulsifier and solubilizer in cosmetic formulations; differs from Trideceth-6 by degree of ethoxylation.

emulsifiersurfactantsolubilizer
Helps blend oil and water phases in emulsionsImproves product texture and spreadabilityMild surfactant with low irritation potential
Surfactant
Trideceth-6

A nonionic ethoxylated tridecanol (6 EO units) used as an emulsifier and solubilizer in sunscreens and lotions.

emulsifiersurfactantsolubilizer
Stabilizes oil-in-water emulsionsHelps solubilize lipophilic ingredients in aqueous systems
May contain trace levels of 1,4-dioxane if not properly purified (common PEG concern)
