Magnasoft Derma NT

Magnasoft Derma NT textile enhancer is a patented, quat functional silicone copolymer with a repeating block structure that combines several chemical entities in one linear molecule. Close to self-emulsifiable, Magnasoft Derma NT textile enhancer can be applied by spray but is particularly well suited for exhaust applications, where its outstanding emulsion stability allows it to deliver full benefits to the end user.

Magnasoft Derma NT textile enhancer is a new textile auxiliary agent designed to deliver a hydrophilic, voluminous, silky hand to all types of fabrics at lower use levels than other products and, very significantly, to retain this performance attributes through several home laundry cycles.

Key Features and Benefits:

• Combines a silky feel and a rich, bulky hand for a unique and unusually powerful softness effect.
• Does not alter the hydrophilic nature of cotton and cotton blends.
• Increases the hydrophilicity of synthetics.
• Provides stretch recovery with a significant elastomeric effect, particularly on knits.
• Gives in-depth softness.
• Is effective on virtually all types of fibers.
• Provides softness and durability effects that are fast to at least ten home laundry washes and particularly pronounced with cellulosic fibers.
• Almost self-emulsifiable; it can generate emulsions that possess extreme shear and pH stability (acid and alkaline)
• Causes virtually no yellowing of white or light shade goods.
• Does not affect the color of dark fabrics.
• Odor-free

 

Typical Physical Properties:

 

Appearance	Colorless to slightly brown fluid
Viscosity, cSt, 25°C/77°F	15,000
Density, gr/cm3	0.980

 

Potential Applications:

Magnasoft Derma NT textile enhancer is a textile auxiliary agent that may add significant value to all types of knit and woven fabrics. Magnasoft Derma NT textile enhancer is particularly effective on knits, providing the typical silicone softener effects and increasing their stretch recovery. Magnasoft Derma NT textile enhancer is effective on woven fabrics and is compatible with durable press resin, and fluorocarbon soil release finishes.

Magnasoft Derma NT textile enhancer is generally applied as a water emulsion. Due to its polar nature, Magnasoft Derma NT textile enhancer can be easily emulsified using simple mixing devices and containers widely available throughout the industry. There is no need for homogenization or colloid milling.

Magnasoft Derma NT textile enhancer emulsions possess extraordinary shear stability in a wide pH range (3-12) at temperatures up to boiling and in the presence of high salts. Tests in a jet dyer (liquor to goods ratio 1:10, 40°C /104°F, pH 4-5, 20 min, pump level 6) demonstrated excellent emulsion stability. As a result, Magnasoft Derma NT textile enhancer can be used under demanding conditions (jet finishing, EVAC, etc.).

Ingredients	Twenty Percent Actives Formulation Weight %	Forty-Three Percent Actives Formulation Weight %
Magnasoft Derma NT textile enhancer	23.5	50.6
Tridecyl Alcohol 6 EO Ethoxylate	10.5	25.8

Procedure:

• Charge Magnasoft Derma NT textile enhancer and ethoxylates. Mix well till entirely homogeneous.
• Dissolve the sodium acetate and acetic acid into the water.
• Slowly add the water solution to the silicone/surfactant blend while mixing. Avoid stirring too much air into the mixture.
• Filter into the containers.

Performance Comparision:

The data in Table 2 demonstrate excellent softness, good wettability, and no yellowing of fabrics treated with Magnasoft Derma NT textile enhancer. The various products listed in these tables were emulsified to a 20% actives emulsion and used at either 15 g/lt (for the 0.25% silicone pick up) or at 30 g/lt (for the 0.5% silicone pick up).
