Chemistries

Narrow range ethoxylates

NR ethoxylates are nonionic surfactants (nonionic surface-active agents). Narrow range ethoxylates are readily biodegradable and Narrow range ethoxylates have lower free alcohol and a peaked ethoxymer distribution around the target level of ethoxylation. These specialty alkoxylated surfactants offer improved performance compared to conventional ethoxylates.

All of the following surfactants have received the EPA's Safer Choice approval and been granted a Full Green Circle. You can see these approvals and listing at www.cleangredients.org under the Harcros Chemicals Inc. company page.

T-Det® A 26-Series NR ethoxylates are based on Harcros patented narrow range technology. Narrow range ethoxylates have lower free alcohol and a peaked ethoxymer distribution around the target level of ethoxylation. Their cloud point and solubility make these products suitable for use in a wide variety of formulations including hard surface cleaners, laundry detergents and all-purpose cleaners. Learn more about our alkoxylation capabilities.


T-Det® A 26-Series consists of linear C12-C16 ethoxylates. These products exhibit excellent detergent properties and can be used in a wide variety of formulations.

Compatibility, Handling & Storage

Due to its nonionic structure, this product is compatible with anionic and cationic surfactants and is stable in the presence of acids, bases, and salts. Please refer to SDS for further information

FAQ

Frequently Asked Questions - Narrow Range Ethoxylates

Find answers to common questions about narrow range ethoxylates

Narrow range ethoxylates are nonionic surfactants with a narrow distribution of ethylene oxide (EO) units, providing more consistent performance compared to broad range ethoxylates. They offer improved properties including better cloud point control, more predictable performance, and enhanced compatibility in formulations.
Narrow range ethoxylates offer more consistent performance, better cloud point control, improved formulation predictability, enhanced compatibility with other ingredients, and more uniform properties. They are particularly valuable in applications requiring precise performance characteristics.
Narrow range ethoxylates are used in home care (detergents), personal care (shampoos, body washes), textile processing, agriculture, and industrial applications where consistent performance is critical.
Narrow range ethoxylates have a tighter distribution of EO units, resulting in more consistent properties, better cloud point control, and more predictable performance. Standard ethoxylates have a broader distribution, which can lead to more variable performance characteristics.
