Abstract

A cationic surfactant for shampoo or cosmetics is prepared from more raw chemical materials through proportioning, synthesizing, centrifugal separation, washing, vacuum drying and pulverizing. Its advantages are high opsonizition and visosity increasing power, and no collection.

Description

Cation guar gum

The invention belongs to a kind of prescription and production method of macromolecule cation tensio-active agent.

Existing like product cationic hydroxyethyl cellulose, conditioning property, thickening capabilities are poor, are easy to generate and gather, and life-time service makes hair produce the sense of bearing a heavy burden.

The objective of the invention is, a kind of chemical formulation and production method of novel high polymer cats product of energy place of cation Natvosol is provided.

The present invention is by the number of chemical raw material, is prepared from through preparation, synthetic, centrifugation, washing, impurity elimination, vacuum-drying, pulverizing etc., and key is that the scope and the production method of each component is:

A. fill a prescription

Guar gum flour 20--30% 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride 7--12% sodium hydroxide 2--5% white carbon black 0.1--0.3% alcohol (95%) 50--70% deionized water 5--10% (weight percent)

B. production method (by prescription)

1. building-up reactions

Under good the stirring, guar gum is dispersed in the alcohol, add white carbon black, sodium hydroxide solution successively, treat that temperature rises to 55 ℃ after, add 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride, temperature remains on 55--60 ℃, reacts 2--3 hour;

2. centrifugation

The feed liquid that reaction is good is centrifugal, carries out solid-liquid separation;

3. washing impurity elimination

Alcohol with 80% washing leaching cake half an hour under 40--45 ℃ temperature, and then centrifugal washing again, repeatedly several times, meet the requirements to impurity;

4. filter cake vacuum-drying to moisture content is met the requirements;

5. pulverize, sieve, pack and be finished product.

Ultimate principle

(1) 3-chloro-hydroxypropyl-trimethyl ammonium chloride carries out closed loop under the alkali effect

(2) epoxypropyl three ammonium chlorides and guar flour (polygalactomannan) carry out etherification reaction.CH ₂-CHCH ₂N ⁺(CH ₃) ₃CL+(C ₁₈H ₃₀O ₁₅) _n-C ₁₈H ₂₉O ₁₅-

Using method of the present invention is

Be used for products such as pearly shampoo, body lotion, Liquid soap, consumption is 0.2--0.5%.In use, cation guar gum should be added in the deionized water under good the stirring, add the EDTA of formula ratio, or transfer to pH value 6.0--6.5 with citric acid, cation guar gum dissolves rapidly, adds other raw material more successively.

Advantage of the present invention is

Cation guar gum is compared with the positively charged ion hyetellose, all improve a lot at aspects such as conditioning property, thickening capabilities, and the cation guar gum life-time service does not have and gather, and can not make hair produce the sense of bearing a heavy burden.

Embodiment

Prescription:

Guar gum flour 100kg, 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride 32kg, caustic soda 10kg, white carbon black 0.3kg, alcohol (95%) 205kg, deionized water 25kg.

Production method:

1. building-up reactions

Under good the stirring, guar gum is dispersed in the alcohol, add white carbon black, sodium hydroxide solution successively, treat that temperature rises to 55 ℃ after, add 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride, temperature remains on 58 ℃ of reactions 2 hours 30 minutes.

2. centrifugation

The feed liquid that reaction is good is centrifugal, carries out solid-liquid separation;

3. washing impurity elimination

Alcohol with 80% is washing leaching cake under 40--45 ℃ temperature, half an hour, and then centrifugal washing again, repeatedly several times, meets the requirements to impurity;

4. filter cake vacuum-drying to moisture content is met the requirements;

5. pulverize, sieve, pack and be finished product.
