No neutralization step
The salt goes straight into the reaction, so you skip dosing caustic into MCA and handling the heat it releases.
SMCA
Chloroacétate de sodium (SMCA) Fournisseur de Chine
Chloracétate de sodium (SMCA, sodium monochloroacetate) is the pre-neutralized form of MCA, used where a process needs the chloroacetate group without adding caustic first — betaine surfactants, CMC and carboxymethylated intermediates. SUNCHEM supplies SMCA in 25 kg bags with a batch COA on every shipment.

Présentation du produit & avantages clés
SMCA carries the same reactive –CH₂Cl group as monochloroacetic acid, already neutralized as the sodium salt. Charging the salt avoids the heat and extra water of neutralizing MCA in the reactor, which is why it is the usual feed for cocamidopropyl betaine and other amphoteric surfactants, and an option for CMC and carboxymethyl starch.
Buyers usually check assay, humidité, sodium chloride and the pH of a solution: together they decide the salt load and the residual chloroacetate in the finished product.
Standard feed for betaines
Quaternizing fatty amidoamines and tertiary amines with SMCA is the established route to cocamidopropyl betaine and lauryl betaine.

Applications par industrie
Where SMCA is used, et que confirmer avant de changer d'approvisionnement.
Bétaïne & amphoteric surfactants
Reacted with fatty amidoamines such as cocamidopropyl dimethylamine, or with alkyl dimethylamines, to make cocamidopropyl betaine (CAPB), lauryl betaine and related amphoterics for shampoos, body wash and detergents.

|---|---|
| Betaine or CMC plant that neutralizes MCA today | SMCA — charge the salt directly |
| Process that needs the free acid | Monochloroacetic acid (MCA) |
| Low residual chloroacetate in the finished product | Agree assay and moisture limits, and check stoichiometry in a trial |

SMCA vs monochloroacetic acid
Faites glisser ou faites défiler horizontalement pour voir toutes les colonnes →
| Produit | CAS | Formule | Mol. poids | When to choose |
|---|---|---|---|---|
| SMCA | 3926-62-3 | C₂H₂ClNaO₂ | 116.48 | Pre-neutralized; common in betaine and CMC plants that dose the salt |
| MCA | 79-11-8 | C₂H₃ClO₂ | 94.50 | Acid form; most CMC, herbicide and pharma routes |
Both deliver the same –CH₂COOH group. Choose by how your process is set up, and confirm with a trial.
Emballage & stockage
Emballage
25 sacs de kg. Tell us your pallet pattern and labeling requirements with the order.
Stockage
Keep bags closed in a cool, dry place; SMCA takes up moisture. Store away from strong acids and oxidizers and follow the SDS for handling.
Transport
Classified as toxic for transport (ET 2659, Classe 6.1, GE III); it ships with dangerous-goods documents.

Bétaïne, CMC or an intermediate: each sets different limits for assay, moisture and chloride. Tell us which one and the grade you make.
Comparez les chiffres qui comptent
Put assay, humidité, NaCl and solution pH on the same COA template as your incoming inspection, so offers are compared like for like.
Plan for dangerous goods
SMCA ships as UN 2659, Classe 6.1. D'accord sur l'emballage, labeling and the destination port early so the booking does not delay the first order.

Voir le produit →Chloroacétate de sodium (SMCA) FAQ
What is sodium chloroacetate used for?
Mainly to make betaine surfactants such as cocamidopropyl betaine, and as the etherifying agent for CMC and carboxymethyl starch. It is also used in pesticide, pharmaceutical and dye-intermediate synthesis.
What is the difference between SMCA and MCA?
SMCA is the sodium salt of monochloroacetic acid. It supplies the same reactive group but is already neutralized, so you do not have to add caustic to MCA in the reactor.
How is SMCA packed and shipped?
Dans 25 sacs de kg. It is classified as toxic for transport (ET 2659, Classe 6.1, GE III) and ships with dangerous-goods documents.
Can I get the TDS and a sample before ordering?
Oui. Send your application and planned test; we provide the TDS and SDS with the quotation and arrange a sample sized for your trial.
