What is PPG-2 Hydroxyethyl Cocamide and what is it used for?
PPG-2 Hydroxyethyl Cocamide (CAS 201363-52-2) is a coconut-derived nonionic amide surfactant. It is used in personal-care cleansers and lotions as an emulsifier, emollient and skin- and hair-feel agent, and as a foam and viscosity modifier in surfactant systems.

Request SDS →PPG-2 hydroxyethyl cocamide (CAS 201363-52-2) is a propoxylated coconut-fatty-acid amide and a mild nonionic surfactant. Formulators reach for it when a single ingredient needs to do several jobs at once: cleanse gently, stabilize and refine foam, lend a soft emollient afterfeel, and solubilize fragrances and oily actives into water-based systems. Because it carries no charge, it plays well across anionic, amphoteric, and other nonionic surfactants, which is why it shows up as a workhorse co-surfactant in personal-care and cleansing formulas where mildness and sensory quality matter.
What it is and why it works
Structurally, it pairs a coconut-derived fatty acid chain with a hydroxyethyl (propoxylated ethanolamine) head. That combination is what gives it its dual personality. The fatty portion delivers emolliency and a refatting, conditioned skin feel; the propoxylated, hydroxyl-bearing head provides nonionic surfactancy and water compatibility. The result is a clear-to-amber liquid that behaves less like a harsh primary detergent and more like a mildness-and-feel modifier. It thickens through shear-thinning rheology, holds foam together, and helps marry oil-loving and water-loving phases without the irritation potential associated with stronger anionic systems.
Applications by sector
Cleansing and personal care
This is the primary home for the material. In shampoos, body washes, shower gels, bubble baths, and facial cleansers, PPG-2 hydroxyethyl cocamide is used as a secondary surfactant to soften the harshness of the anionic base (typically a sulfate or sulfosuccinate). It improves foam density and stability, contributes a creamier lather, and leaves a refatted, non-stripped afterfeel on skin and hair. Its nonionic character means it can be dosed into existing surfactant blends without disrupting charge balance, so it is a practical lever for reformulating toward a milder claim profile.
Skin care
In lotions, cleansing milks, and emulsified cleansers it works as an emollient and as a solubilizer, helping carry fragrance oils, lipophilic actives, and emollient esters into otherwise aqueous formulas. That solubilizing ability lets formulators add oily ingredients at usable levels while keeping the finished product clear or stable, which is why it appears in both rinse-off and leave-on skin-care formats.
Conditioning
The fatty-amide backbone deposits a light conditioning film, so it is also used in hair conditioners, leave-in treatments, and moisturizing systems where a soft, smooth feel is the goal. It is rarely the sole conditioning agent; more often it complements cationic conditioners or supports slip and detangling alongside them.
Household and industrial cleansers
Outside personal care, its nonionic surfactancy and foam behavior make it useful as a co-surfactant in hand cleansers, hard-surface and HI&I cleaning products, and textile auxiliaries. Nonionics are valued in these systems because they tolerate hard water and electrolytes better than anionics and can fine-tune foam and wetting without adding charge-related instability.
Forms and grade
PPG-2 hydroxyethyl cocamide is typically supplied as a liquid, ranging from clear to pale yellow or amber depending on grade and lot. It is most often offered at high active content rather than as a dilute solution, though exact active percentage, color, and viscosity vary by manufacturer and grade. We confirm assay, appearance, and identity on the Certificate of Analysis issued per lot rather than relying on generic literature values, so formulators can match incoming material to their specification before it enters production.
Handling
Handle as a personal-care surfactant raw material in line with good manufacturing practice. The lot-specific Safety Data Sheet governs storage, personal protective equipment, spill response, and incompatibilities, and should be reviewed before use. We provide the SDS together with the CoA for every shipment.

Frequently Asked Questions
What is PPG-2 hydroxyethyl cocamide?
PPG-2 hydroxyethyl cocamide (CAS 201363-52-2) is a propoxylated coconut-fatty-acid amide and a mild nonionic surfactant. It is used in personal-care and cleansing formulations as a co-surfactant, emollient, foam and viscosity modifier, and solubilizer.
What is PPG-2 hydroxyethyl cocamide used for?
Formulators use it as a mild secondary surfactant in shampoos, body washes, and facial cleansers, as an emollient and solubilizer in skin care, and as a conditioning and foam-stabilizing agent. It also serves as a nonionic co-surfactant in household, HI&I, and textile cleaning products. It is supplied as a raw material to manufacturers.
Why is it considered a mild surfactant?
It is nonionic, so it carries no charge and is gentler on skin than strong anionic detergents. In a formula it tempers the harshness of the anionic surfactant base while improving foam quality and leaving a refatted, conditioned afterfeel, which makes it a common building block in mildness-focused formulations.
What is it made from?
It is synthesized from coconut-derived fatty acids combined with a propoxylated ethanolamine (hydroxyethyl) moiety, placing it in the nonionic cocamide surfactant class. Full identity data are provided on the CoA per lot.
What is the INCI name and CAS number?
The INCI name is PPG-2 Hydroxyethyl Cocamide and the CAS number is 201363-52-2. We provide identity and assay data on the Certificate of Analysis per lot.
What packaging is available for bulk supply?
We supply PPG-2 hydroxyethyl cocamide to formulators in industrial packaging such as drums and pails, with a CoA and SDS per lot. Request a quote with your target volume and packaging preference for current bulk pricing.
Is PPG-2 hydroxyethyl cocamide safe?
The Cosmetic Ingredient Review (CIR) Expert Panel concluded in its July 2019 final report that PPG-2 hydroxyethyl cocamide, reviewed among 40 alkoxylated fatty amides, is safe in cosmetics in the present practices of use and concentration when formulated to be non-irritating. FDA 2019 VCRP data list it in 354 cosmetic formulations, the most of any ingredient in that review. Confirm hazard and handling details against the lot-specific SDS for your grade.
What does PPG-2 hydroxyethyl cocamide do in shampoo?
It serves as a nonionic secondary surfactant that builds foam density, stabilizes lather, and softens the harshness of the anionic base. Reported rinse-off use concentrations reach 4%, per the Council survey data cited in CIR’s 2019 assessment, and 338 of its 354 reported cosmetic uses are rinse-off products. Because the molecule carries no charge, it drops into sulfate, sulfosuccinate, or amphoteric systems without disturbing charge balance.
Is PPG-2 hydroxyethyl cocamide bad for hair?
Published review data do not support that concern. In hair products it deposits a light conditioning film, stabilizes foam, and improves wet slip. The CIR Expert Panel reviewed reported hair-preparation use at concentrations up to 7.5% and concluded in 2019 that it is safe in the present practices of use and concentration when formulated to be non-irritating. Verify each lot against its CoA rather than literature values.
What is PPG in skincare?
PPG stands for polypropylene glycol. In an INCI name, the number after PPG is the nominal count of propylene-oxide (propoxyl) units on the molecule, so PPG-2 hydroxyethyl cocamide carries a short two-unit propoxyl chain on its amide head. Commercial material is a mixture, with a distribution of propoxyl groups and coconut-amide chain lengths. CIR reviewed polypropylene glycols separately in 2012 and found them safe in the present practices of use and concentration when formulated to be non-irritating.
