The long-term storage stability of a waterborne pigment concentrate is outwardly reflected in whether the particle size increases again, whether sedimentation occurs, whether flocculation develops, whether viscosity drifts, and whether color development remains stable. At its core, it depends on ...
In small-molecule drug discovery, the value of a molecular building block depends not only on whether its structure is novel, but also on whether it can be effectively introduced into target molecules and provide well-defined variables for structural optimization.
Many personal and home care products encounter the same issue during development: they smell very fragrant from the bottle and have a noticeable scent during use, but after rinsing, towel-drying, air-drying, or standing for a period of time, the fragrance quickly weakens. Common solutions ...
Most coatings use resin as the continuous phase and typically exhibit high electrical resistance after film formation. For ordinary decorative and protective coatings, this insulating property is not necessarily a problem. However, in applications such as antistatic flooring, electronic-industry ...
When daily chemical products show a decrease in viscosity during summer, the issue should not simply be attributed to “high temperature.” An increase in temperature does reduce the viscosity of most liquid systems, but the extent of viscosity thinning mainly depends on whether the thickening ...
“Neutral putty,” “821 putty,” and “ordinary interior wall putty” are not standard classifications within the same category. Neutral putty is more of a market term formed according to the acidity/alkalinity or cementitious system characteristics of the formulation. 821 putty is more ...
In personal care and household formulations, many key challenges are related to oil, water, and interfaces. Sebum, oily soils, fragrance oils, and oil-soluble actives usually do not readily enter the aqueous phase; water also does not easily wet oily, waxy, or low-surface-energy surfaces. ...
In personal and household care formulations such as shampoos, body washes, hand soaps, dishwashing detergents, and hard-surface cleaners, foam performance is often directly perceived by consumers and is also commonly used by formulators to assess the state of a formulation system. During product ...
Cationic surfactants are a class of surfactants whose hydrophilic end carries a positive charge in aqueous solution. Like other surfactants, they have an amphiphilic molecular structure: one end is hydrophilic, and the other is hydrophobic. What makes cationic surfactants different is that their ...
