Solvents, wetting and defoaming

n-Butyl acetate

Distinguish n-butyl acetate from other butyl acetate isomers before comparing resin solubility and evaporation behavior.

Solvents, wetting and defoaming

Isopropyl alcohol

Isopropyl alcohol can serve as a volatile co-solvent. Specify nonvolatile residue separately for electronics or high-finish surface cleaning.

Solvents, wetting and defoaming

Propylene glycol monomethyl ether (PM)

PM is a glycol ether co-solvent. Distinguish it from its acetate ester and specify isomer composition and moisture.

Solvents, wetting and defoaming

Polyether-modified siloxane wetting agents

Evaluate substrate wetting on the actual surface at production coating speed. Check foam and intercoat adhesion at the same time.

Solvents, wetting and defoaming

Silicone defoamers

Balance foam control with compatibility. Excessive incompatibility can cause craters or oil spots.

Metal surface pretreatment

Sodium metasilicate

Anhydrous and pentahydrate metasilicate grades have different effective alkalinity. Calculate cleaning-bath additions for the form purchased.

Metal surface pretreatment

Technical-grade phosphoric acid

For metal treatment, specify both acid concentration and impurities that affect the conversion coating. Qualify the industrial grade separately from high-purity acid.

Metal surface pretreatment

Zinc phosphate conversion coating chemicals

Zinc phosphating is generally quoted as a system. Specify bath make-up, replenisher and surface conditioning before agreeing film and corrosion tests.

Metal surface pretreatment

Zirconium conversion coating chemicals

Zirconium conversion films are thin. Evaluate the substrate, film formation and complete coating system rather than relying on visible color.

Detergency, wetting and foam

Fatty alcohol ethoxylates (AEO)

Fatty chain length and average EO number affect wetting, cloud point and cold appearance. Request AEO-7 and AEO-9 as separate grades.

Detergency, wetting and foam

Linear alkylbenzene sulfonic acid (LABSA)

LABSA is an acid intermediate. Distinguish it from neutralized sodium LAS when checking identity, active content and processing requirements.

Builders, chelation and anti-redeposition

Detergent zeolite 4A

Detergent zeolite 4A removes hardness through ion exchange. Also assess powder dispersion and rinse residue.

Builders, chelation and anti-redeposition

Tetrasodium glutamate diacetate (GLDA)

Tetrasodium GLDA is often evaluated in solution. Align the active basis for pricing and specify pH and hardness for performance comparisons.

Bleaching, stain removal and enzymes

Proteases for detergents

Compare detergent proteases by a common activity method and a defined protein stain. Check activity retention after storage.

Bleaching, stain removal and enzymes

Amylases for detergents

Evaluate detergent amylases on starch-based food stains under the actual wash time, temperature and formulation.

Bleaching, stain removal and enzymes

Lipases for detergents

For lipases on fatty stains, define the grease, wash cycle and formulation compatibility conditions.

Thickening, moisturization and emulsification

Glycerol (glycerin)

Glycerol absorbs moisture. Calculations based on neat glycerol or commercial solution affect the water balance and finished skin feel.

Thickening, moisturization and emulsification

Propylene glycol (1,2-propanediol)

Propylene glycol serves as a humectant and co-solvent. Grade, water content and impurity requirements depend on end use.

Thickening, moisturization and emulsification

Carbomers

Carbomer grade, dispersion and post-neutralization viscosity govern gel behavior. A single viscosity value cannot establish grade equivalence.

Thickening, moisturization and emulsification

Cetearyl alcohol

Cetearyl alcohol is a fatty alcohol mixture. The C16/C18 ratio can change cream consistency and texture on crystallization.
