Common Name(s): Peg-10 oleamine,polyoxyethylene-10 oleylamine,peg-10 octadecenylamine

CAS Number: 26635-93-8

DESCRIPTION

What It Does: Conditions hair and skin while reducing static in water-based formulas.

Why It's Used: Used as a mild amine-based conditioning surfactant with antistatic properties; peg-10 modification provides good water compatibility.

How It Works: 10 eo units give hlb ~12–13; amine terminus provides mild cationic character; oleyl chain provides conditioning emolliency.

Typically Found In: Conditioning products,antistatic hair care,skin conditioning formulas

TECHNICAL DETAILS

Primary Category: Functional ingredient – surfactant

Secondary Functions: Antistatic,conditioning,emulsifying

Application Areas:

Typical Concentration Range: 0.5%–3%

SOURCING & ETHICS

Vegan Status: Conditional - feedstock declaration required

Halal Status: Unverified - feedstock declaration required (plant, animal and petrochemical routes all exist)

Source Notes: Oleylamine from oleic acid reduction (plant origin); eo from petrochemical. [audit 2026-07-29 rev2: origin-dependent: the same inci exists in plant, animal and petrochemical versions and the name does not discriminate. determination requires shariah-panel sign-off.]

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Comedogenicity Rating: 1/5 – low

Sensitivity Concerns: Generally well tolerated at typical use levels; mild cationic character.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Good safety profile. ewg score: 1–2.

Works Well With: Cationic conditioners,amphoteric surfactants

Avoid Combining With: Avoid high concentrations with anionic surfactants

SCIENTIFIC NOTE

Ethoxylated amines become less cationic as eo count increases; peg-10 oleamine has predominantly nonionic character at most formulation ph values; cas 26635-93-8.
