Amino acid shampoo composition and preparation method thereof

Abstract

The invention relates to a cleaning composition and a preparation method thereof, belonging to the technical field of cosmetics. The composition comprises, by weight, 15 to 50% of an amino acid surfactant, 10 to 30% of sodium alpha-olefinsulfonate and 15 to 50% of a betaine surfactant. The composition provided by the invention effectively overcomes the problem of difficulty in thickening of conventional products with the amino acid surfactant as a main surfactant, realizes thickening mainly through complex formulation of an anionic surfactant and an ampholytic surfactant, and constructs a micelle from sodium C14-16 olefin sulfonate and the betaine surfactant in a proper ratio so as to realize system thickening; other thickening agent is not needed; cold preparation can be realized, so production time is substantially reduced; and the prepared cleaning composition has abundant and fine foam, is greatly saved in cost and overcomes the problem of difficulty in thickening of the amino acidsurfactant and the problem of low foam of the amino acid surfactant.

Description

technical field [0001] The invention belongs to the field of cosmetics and relates to a low-cost thickened cleaning composition. Background technique [0002] Amino acid shampoos generally have problems of high cost and low foam in the market. The main reason is that the cost of amino acid surface activity is high, the cheapest is more than 12 yuan / kg, and the expensive one is even nearly 100 yuan / kg. The foam height of amino acid surfactants is lower than that of commonly used sulfate surfactants, and the biggest problem with amino acid surfactants is that it is difficult to thicken. Conventional shampoo thickeners often cannot thicken effectively, or there will be Obvious defoaming, such as cocamide MEA, PEG-150 distearate, PEG-120 methyl glucose dioleate, acrylic acid (ester) copolymer, the thickening effect is very limited. In recent years, in order to solve the problem of difficult thickening in the corresponding market, such as PEG-120 methyl glucose triisostearate, ...

AI Technical Summary

Problems solved by technology

Mainly due to the high cost of amino acid surface activity, the cheapest one costs more than 12 yuan / kg, and the expensive one is even nearly 100 yuan / kg

The foam height of amino acid surfactants is lower than that of commonly used sulfate surfactants, and the biggest problem with amino acid surfactants is that it is difficult to thicken. Conventional shampoo thickeners often cannot thicken effectively, or there will be Obvious defoaming, such as cocamide MEA, PEG-150 distearate, PEG-120 methyl glucose dioleate, acrylic acid (ester) copolymer, the thickening effect is very limited

In recent years, in order to solve the problem of difficult thickening in the corresponding market, such as PEG-120 methyl glucose triisostearate, PEG-150 pentaerythritol tetrastearate, acrylic acid (ester) / C10- 30 alkanol acrylate crosslinked polymers and other products that effectively thicken amino acid surface activity, but they have various problems such as high cost, defoaming, need for heating, and complicated process

[0003] In addition, in the prior art, only amphoteric surfactants are used to thicken amino acid surfactants. For example, Lu Haiwei studied the compounding of amino acid / amphophoteric surfactants, and found that cocamide betaine is effective for different amino acid surfactants. The surface activity and thickening effect are different. It has a thickening effect on sodium lauryl sarcosinate and sodium cocoyl alaninate, but it has a thickening effect on sodium lauryl glutamate, sodium cocoyl methyl taurate and coconut oil. Sodium oleoyl glycinate has no effective thickening effect (Lu Haiwei. Amino acid / amphoteric surfactant compound thickening system and rheological research [D]. East China University of Science and Technology, 2013.)
