NP-10

NP-10 is a nonionic surfactant, chemically known as Nonyl Phenol Ethoxylate (10 moles EO), widely used in textile processing, detergent formulation, and various industrial applications. It is valued for its excellent wetting, emulsifying, dispersing, and detergency properties, making it a versatile auxiliary in both textile and non-textile industries.

In textile wet processing, achieving uniform wetting and penetration of chemicals is essential for consistent dyeing and finishing results. NP-10 plays a crucial role in improving liquor penetration by reducing surface tension, allowing dyes and auxiliaries to interact more effectively with fibers. Because it is nonionic, NP-10 remains stable across a wide range of pH levels and water hardness conditions.

Performance Characteristics

NP-10 exhibits strong emulsification power for oils, waxes, and greases. This makes it highly suitable for scouring, desizing, washing, and oil removal processes. It performs efficiently at both low and high temperatures, providing flexibility in different processing environments.

Unlike ionic surfactants, NP-10 does not react with cationic or anionic chemicals, which ensures compatibility with a broad range of textile auxiliaries, dyes, and finishing agents.

Key Applications

Textile Scouring & Washing
NP-10 is commonly used to remove natural oils, spinning oils, and impurities from cotton, polyester, and blended fabrics.

Wetting Agent in Dyeing
Improves initial wetting and penetration of dyes, especially in reactive and disperse dyeing processes.

Emulsifying Agent
Used to emulsify oils, silicones, and waxes in textile finishing formulations.

Detergent & Cleaner Formulation
An important raw material in liquid detergents, industrial cleaners, and degreasing agents.

Industrial Applications
Widely used in agrochemicals, paints, coatings, leather processing, and metal cleaning due to its strong surface-active properties.

Benefits of NP-10

• Excellent wetting and penetration ability

• Strong emulsification of oils and greases

• Stable over wide pH and temperature range

• Compatible with most textile chemicals

• Effective in hard and soft water

• Improves processing efficiency and fabric cleanliness

Typical Usage Guidelines

NP-10 is usually diluted with water before application. Dosage depends on fabric type, process stage, and level of impurities.

General Guidance:

• Low dosage for wetting and penetration

• Medium dosage for washing and scouring

• Higher dosage for heavy oil or grease removal
  Always conduct laboratory trials before bulk use to determine optimal concentration.

Importance for Bangladesh Textile Industry

Bangladesh’s textile and garments industry relies heavily on efficient wet processing chemicals to ensure quality, productivity, and cost control. NP-10 is widely used in local dyeing mills, washing plants, and finishing units because of its consistent performance and affordability.

It supports high-volume production by improving bath efficiency, reducing reprocessing, and ensuring uniform fabric treatment. For export-oriented factories, NP-10 helps maintain fabric cleanliness and process reliability.

Storage & Handling

Store NP-10 in a cool, dry place in tightly closed containers. Avoid prolonged exposure to direct sunlight. Under proper storage conditions, the product maintains stability for extended periods.

Safety Information

NP-10 is intended for industrial use only. Operators should follow standard chemical handling practices, including protective gloves and eye protection.
