Ethyl Lauroyl Arginate
Ethyl Lauroyl Arginate, commonly abbreviated LAE, is a cationic surfactant antimicrobial derived from the natural amino acid L-arginine, lauric acid, and ethanol.
The full chemical name is ethyl-Nα-dodecanoyl-L-arginate hydrochloride. The molecule has CAS number 60372-77-2 and is used as a broad-spectrum food antimicrobial active against Gram-positive and Gram-negative bacteria, yeasts, and moulds.
We source bulk Ethyl Lauroyl Arginate from top China manufacturers for our partners. The manufacturer is in Henan. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Ethyl Lauroyl Arginate is a white to pale-yellow free-flowing powder of 85 percent minimum active content.
A standard food grade is the pure active, for incorporation into liquid pre-blends made at the customer's site.
Ready-to-use liquid concentrates are also produced. These dissolve LAE at 5 to 20 percent in a glycerol or propylene-glycol carrier for direct dosing into surface sprays and brines.
A cosmetic and personal-care grade is produced for use in oral-care, deodorant, and preservative-booster applications, where the cationic profile contributes both antimicrobial and substantivity benefits.
Material ships in 20 kg lined fibre drums or, for liquid concentrates, in 25 kg pails and 200 kg drums.
Applications
- Surface application on ready-to-eat deli meats and cooked sausages
- Poultry chill-tank treatments to reduce surface pathogen loads
- Marinades and brines for whole-muscle and emulsified meat products
- Salad-dressing and mayonnaise systems as a secondary preservative
- Refrigerated dairy desserts and dips
- Bottled and dispensed beverage preservation systems
- Mouthwash, toothpaste, and other oral-care formulations
- Deodorants and antiperspirant sticks as an odour-control active
- Wipes and surface sanitizer concentrates
- Hard-surface cleaners for food-contact equipment
- Cosmetic preservative-booster blends in combination with traditional preservatives
- Pet-food packaging coatings and active-packaging films

How We Help Source Ethyl Lauroyl Arginate
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Ethyl Lauroyl Arginate out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Ethyl Lauroyl Arginate together with other ingredients such as Calcium Propionate, Sodium Diacetate and Sodium Propionate into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Ethyl Lauroyl Arginate received GRAS recognition in the United States in 2005 under FDA GRAS Notice 164. The notification covers use as an antimicrobial in cooked, ready-to-eat meat and poultry products at up to 200 mg/kg.
The U.S. Department of Agriculture Food Safety and Inspection Service issued a separate directive covering use on meat and poultry surfaces, with sanitary-handling expectations.
In the European Union, Regulation 1333/2008 authorises the substance under the additive number E243 for surface treatment of heat-treated meat products and sets category-specific maximum-use limits.
The cosmetic and oral-care use is regulated under EU Regulation 1223/2009 as a preservative entry in Annex V, with concentration limits set by product category.
Kosher and Halal certifications exist from the main producers, with Halal certification dependent on the source of the lauric acid used in the acylation step.
Manufacturing Process
Ethyl Lauroyl Arginate is manufactured by a two-step synthesis from L-arginine, ethanol, and lauric acid.
In the first step, L-arginine is esterified with ethanol under acid catalysis to give L-arginine ethyl ester hydrochloride. The reaction runs in excess ethanol at moderate temperature until conversion is high enough for the second step.
The second step is an N-acylation of the α-amino group of the arginine ester with lauroyl chloride or activated lauric acid. The acylation is carried out under controlled pH so that only the α-amine reacts, leaving the guanidinium group of the arginine side chain intact.
The crude product is recrystallised from aqueous ethanol to remove residual amino acid and fatty-acid impurities. Final drying delivers a powder meeting food-grade purity specifications.
The original process and the dominant commercial supply were developed by Vedeqsa, the food-ingredients arm of LAMIRSA in Spain, which holds the original GRAS notification.
