  Dispersant and wetting agent , AkzoNobel is undoubtedly a leader in the agrochemical industry in the production of wetting and dispersing agents based on naphthalene sulfonates
The trade name is morwet & reg; Various naphthalene sulfonates and naphthalene sulfonate polycondensates are famous for their versatility and formula stability to a variety of active components of technical drugs
They have excellent wetting, dispersion, low foam, hard water resistance and caking resistance
Morwet® The product series includes various wetting agents and dispersants for solid (DF, WDG, WP , SP, etc
) and liquid dosage forms (SC, SL, as, FS, etc
) 1
  Solid dosage form , Solid dosage forms are more and more popular because they do not contain solvents, are more friendly to the environment and make workers safer in the field
Solid dosage forms need to come from the wettability, dispersion and suspension characteristics provided by surfactants
Morwet® Brand naphthalene sulfonate can consistently meet the requirements of formula designers and users
Morwet & reg; Naphthalene sulfonate and naphthalene sulfonate polycondensate can be used in wettable powder (WP), water dispersible granules (WDG), dispersible tablets (DT), extruded granules (g), soluble powder (SP) and other solid dosage forms In addition to their wetting and dispersion properties, morwet & reg; Naphthalene sulfonate is also useful for granulation production, either by disc granulation, spray drying, extrusion molding or fluidized bed technology
nbsp; For the general recommendations for solid dosage forms, the following initial addition concentrations are the recommended dosage of the dispersant and wetting agent alone
If it is necessary to combine other dispersant wetting agents, the dosage shall be considered separately
For formulation development of WP or WP, the initial formulation should be morwet D-425 as dispersant, morwet EFW is a wetting agent, and the initial concentration should be within the following range:

Products	wettable powder	water dispersible granules	water suspension
Morwet  D-425	2-3%	3-5%	1-3%
Morwet  EFW	1-2%	2-3%	0 5%-2%

  In some cases, if the content of wetting agent is low, morwet D-450 acts as the only additive (both as dispersant and wetting agent, so as to simplify the formula), and the initial addition is 3 ~ 4%
The granulation process will affect the actual need for the concentration of wetting agent and dispersant
The higher the compactness of component granulation, more attention should be paid to the rewetting and disintegrating properties of particles and more dispersants should be added
A robust, durable and widely used formula must be based on the addition of the best surfactant product and the concentration to ensure the required performance 2
  Liquid dosage form , General recommendations for liquid dosage forms, usually water suspended dosage forms (SC) are based on morwet D-425 is a dispersant
For the suspension with solid phase concentration of 480-500g / L, the addition concentration is 2-2
5% (weight); For formulations with higher solid concentration (720 g / L), the d-425 addition concentration must be increased to 3-5%
The amount of surfactant formulation components should be proportional to the surface area of solid particles added to the final formulation
If the average particle size of solid particles is smaller, the surface area is larger, so more surfactants need to be added 3
  Dispersant knowledge , Dispersant is used for uniform suspension of technical components
The development of a fully dispersed formula can ensure the consistency of technical drug components in field application, so as to ensure the efficacy and prevent the occurrence of drug damage as far as possible
Morwet  D-425 is a model of dispersant used in aqueous suspension and dry dosage forms
In terms of dispersing various technical components in different water hardness applications, morwet D-425 naphthalene sulfonate polycondensate is more effective than other products
Using morwet & reg; Dispersant also helps to ensure that the original components are dispersed effortlessly in the sprayer, with excellent dispersion, suspension, hard water, wide application range of pH, high temperature stability, low foam, anti caking and wide spectrum applications
nbsp; To meet the requirements of more challenging formulations, the following performance enhanced morwet & reg; are now available; Dispersant: morwet D-500  Improve suspension stability in hard water applications and provide unique steric effect
It can also act as an effective wetting agent and improve the resuspension performance of the suspension
It can provide excellent dispersion performance in both solid and liquid dosage forms, such as in sulfonylurea WDG
Morwet  D-110  The low melting point technical drug system with high silica content provides hard water suspension and can also contribute to the buffer effect in barrel mixing applications
It is applicable to the formula containing white carbon black and can effectively improve the suspension rate
Morwet  D-450  For simpler formulation system, it can act as wetting agent and dispersant at the same time
In addition, morwet D-450 also contributes to the disintegration of particles in water and improves the suspension of dry dosage form
It is more suitable for highly hydrophobic technical drugs or simplifies the formulation of hydrophilic technical drugs
Morwet  D-390  Dispersant with better cost performance is prepared by compounding alkyl naphthalene sulfonate formaldehyde polycondensate and lignin sulfonate through special process Excellent dispersant, better than lignin and naphthalene sulfonate, can provide better dispersion, heat storage stability and hard water resistance
