What is water-based thickener

Introduction: thickener is mainly used to improve and increase the viscosity of liquid What is water-based thickener? Let's take you to know There are many kinds of thickeners According to the mechanism of action, the thickeners used in practice can be divided into two categories: water phase thickener and oil phase thickener The former has many varieties and the latter is quite few The water-based thickener mainly refers to that in water system, when the thickener reaches a certain concentration, the lipophilic end group is associated to form micelles; in water-based polymer system, the lipophilic group of the thickener is mainly associated with polymer particles, and the polymer compounds that complete the thickening characteristics in this way are called water-based thickeners At present, there are four kinds of thickeners available in the market: inorganic thickener, cellulose, polyacrylate and associated polyurethane thickener 1 Cellulose thickeners have a long history of use and many varieties, including methylcellulose, carboxymethylcellulose, hydroxyethyl cellulose, hydroxypropylmethylcellulose, etc., which used to be the mainstream of thickeners, among which hydroxyethyl cellulose is the most commonly used one 2 polyacrylate thickeners are basically classified into two types: one is water-soluble polyacrylate, the other is acrylic or methacrylic acid homopolymer or copolymer emulsion thickener The thickener is acidic itself, and it must be neutralized with alkali or ammonia to pH8~9 to achieve thickening effect, also known as acrylic acid swelling thickening agent 3 Polyurethane thickener is a newly developed associative thickener in recent years Inorganic thickening agent is a kind of gel mineral formed by water swelling and thixotropy, mainly bentonite, attapulgite, aluminum silicate, etc bentonite is the most commonly used Today's small edition of Baibai safety net gives a brief introduction to what is water-based thickener If you want to know more about the function of thickener and the knowledge of food additives and food safety, please continue to pay attention to our website and hope that today's content can help you Editor in charge: sun Dianwei
