Composite salt-resistant thickening agent, and preparation method and application thereof

Abstract

The invention discloses a composite salt-resistant thickening agent, which belongs to the field of daily chemicals. The composite salt-resistant thickening agent consists of xanthan gum, guar gum and sodium alginate, wherein the weight ratio of the xanthan gum to the guar gum to the sodium alginate is (5-8):(2-5):(1-3); and the composite salt-resistant thickening agent is prepared by the following steps of: dissolving the xanthan gum, the guar gum and the sodium alginate into water in turn; stirring and uniformly mixing; adjusting to the concentration for use by using water; and adjusting pH value to be 6 to 8; and heating at the temperature of between 50 and 80 DEG C for 10 to 60 minutes. The amount of the used thickening agent is 0.01 to 1.0 percent of the weight of the salt-containing daily chemical. The composite salt-resistant thickening agent has acid and alkali resistance, high temperature resistance, anti-freezing effect and does not have toxic or side effect, is excellently matched with a common surfactant (such as sodium alcohol ether sulfate AES, sodium ammonium dodecyl sulfate K12A and the like) in the daily chemical and has the advantages of simple manufacturing process, low technological condition and low comprehensive cost.

Description

technical field [0001] The invention relates to an auxiliary material for daily chemical products, in particular to a composite salt-resistant thickener. Background technique [0002] In recent years, the application of salt (i.e. NaCI) in the field of cosmetics has become more and more extensive. Using the functions of sterilization, disinfection, anti-inflammatory, antipruritic, blood circulation, and cleaning of salt, daily chemical products with different functions can be prepared according to different proportions. These salts Similar daily chemical products are a new generation of household daily chemical products that are pollution-free and non-toxic and side effects that have become popular in the world in recent years. [0003] Adding salt (NaCI) to the formula of daily chemical products has a great influence on the quality stability of the formula. A small amount of salt can thicken the daily chemical products. %) of the salt will destroy the micellar structure fo...

Problems solved by technology

[0008] At present, there is an important problem in common commercially available thickeners for salt-containing daily chemical products: in daily chemical products with high salt content (salt content exceeds 20% in milky daily chemical products), the thickener will be unstable or invalid Or the suspension stability is not ideal, and it cannot achieve the required viscosity, stability, and suspension, so that the product has quality problems such as yellowing, layering, salt sinking, and poor fluidity during the shelf life. The main reasons are Among the many optional thickeners, no thickener suitable for daily chemical products with a salt content of more than 20% has been found; or the performance of a single thickener is not comprehensive enough to combine salt resistance and thickening. Suspension, suspension, and stability are equal to one, which often cannot meet people's needs. Relying on a certain thickener alone can solve the salt-resistant stability of salt-containing daily chemical products, and the effect is ideal.
