IntroductionWhen stress is applied on some matter there occur changes in the structure or the flow of the matter. The study of these changes under the influence of applied stress is known as Rheology.Rheology Modifier is an additive which is used to modify the viscosity of any material. They are also known as Thickening Agent. Rheology Modifiers are classified as Associative and Non Associative Rheology Modifier. Non Associative Rheology Modifiers are the ones which have been used in traditional times. These include hydroxyethyl cellulose (HEC) which contributes desired body in paints, cosmetics and are also used in ideal household products. It also maintains water retention at various levels. But now in modern times we use one of the most common Associative Modifier i.e popularly known as Hydrophobically Modified Alkali Soluble Emulsions which exhibit relatively low solution viscosity. They provide coatings a better rheology. They usually control the viscosity of acqueous syste...
