Abstract
The present invention relates to a thickening agent for a liquid lotion, and a preparation method and the application thereof. The thickening agent is manufactured by mixing polyether and (methyl radical) acrylic acid according to the molar ratio of 1: 0.5 to 1: 6, adding an acid catalyst, keeping temperature between 90 and 180DEG, and stirring 1 to 6 hours for esterification and copolymerization reaction to obtain random copolymer as active constituents. The thickening agent had good densification capability, so the thickening agent can obviously increase product viscosity and effectively reduce product cost when used for preparing a low concentration liquid detergent. The thickening agent has favourable chelating power, can carry out complexation to the metal ions, such as calcium ions, magnesium ions, copper ions, iron ions and the like in water, increases washing effects, has favourable washing and degreasing interoperability, improves the washing action of other surfacetants, and can reduce the greasy feeling of the liquid detergent. The preparation method is a one-step synthesis method, has the advantages of simplicity, convenience, easy operation, no solvent and easy reaction control, and can not pollute products because of the solvents.
Description
Technical field: the present invention relates to a kind of thickening material that is used for liquid lotion, the invention still further relates to its preparation method and application.
Background technology: the effective concentration of liquid detergent is the most critical factor that influences product cost.In order to make the human consumer easy to use, also to satisfy appearance requirement, liquid washing agent should have certain viscosity, should there be the unlikely again trickling of certain fluidity too fast, and the effective concentration that reduces liquid lotion will make product thinning and trickle too fast, so the performance of thickening material directly influences the cost of liquid washing agent.General lower concentration liquid lotion can adopt stearic acid macrogol ester 638, cooperate relatively large NaCl salt to make thickening material, but because of the NaCl consumption big, its viscosity instability, easily make the solution system whiting, its clean effect is not good, when 638 consumptions are big, then can produce Gel mile shape gel, not be suitable for the liquid lotion of preparation good fluidity.In addition,, wish thickening material except good thickening power can be provided, outstanding washability and anti-hard water ability can also be provided, have good cooperative ability, and reduce the soapy feeling of washing composition from the angle of preparation liquid lotion.
Summary of the invention: the object of the present invention is to provide a kind of good thickening capabilities that both had, can effectively reduce the cost of liquid washing agent again, also have good washing, degreasing, chelating function and good cooperative ability simultaneously, and can reduce the thickening material of the soapy feeling of liquid washing agent.
Another object of the present invention provides a kind of preparation method of thickening material of the present invention.
A further object of the invention is that thickening material of the present invention is used in liquid lotion.
The invention provides a kind of thickening material that is used for liquid lotion, the active ingredient that it is characterized in that this thickening material be methacrylic acid or vinylformic acid and polyethers under the acid catalyst effect through esterification, the random copolymers of copolymerization gained, its content is the 80%-98% of thickening material weight, used polyethers and methacrylic acid or acrylic acid mol ratio are between 1: 0.5～1: 6, used acid catalyst accounts for polyethers, the 0.2-3% of methacrylic acid or vinylformic acid and acid catalyst gross weight, and adopt following method preparation: (a) polyethers is mixed with methacrylic acid or vinylformic acid, (b) add acid catalyst, (c) maintain the temperature at 90～180 ℃ and stir 1～6h, carry out esterification, copolymerization makes.
Preferred polyethers is one or more polyoxyethylene nonylphenol ethers, polyoxyethylene glycol, castor oil polyoxyethylene ether, paregal O, polyoxyethylene octylphenol ether, styryl phenyl Soxylat A 25-7, vinylbenzene phenyl Soxylat A 25-7 polyoxypropylene base ether, fatty alcohol-polyoxyethylene ether, Tweens nonionogenic tenside, SYNPERONIC PE/F68.More preferably polyoxyethylene nonylphenol ether, paregal O, fatty alcohol-polyoxyethylene ether.Most preferably be paregal O, fatty alcohol-polyoxyethylene ether.
Preferred acid catalyst is one or more sulfuric acid, nitric acid, thionamic acid, phosphoric acid, toxilic acid, alkyl benzene sulphonate (ABS), chlorsulfonic acid, tosic acid, methylene-succinic acid, grape acid, oxalic acid, citric acid.Most preferably be thionamic acid, tosic acid.
Preferred polyethers and methacrylic acid or acrylic acid mol ratio are 1: 1～1: 2, this is that thickening effectiveness is not remarkable at least because of working as methacrylic acid or vinylformic acid consumption, greatly then thickening effectiveness is good when methacrylic acid or vinylformic acid consumption, but the oneself viscosity of product is very big, stirs difficulty.
Preferred temperature of reaction is 120-150 ℃, this be because during polymerization because the sterically hindered cause of esterification products makes its reaction activity higher, and high temperature just is beneficial to thermal-initiated polymerization, but temperature of reaction Gao Zehui makes the reaction product color and luster darker, is unfavorable for using.
Methacrylic acid or vinylformic acid can replace as methylene-succinic acid, toxilic acid with following one or more unsaturated carboxylic acids, are general preferable methyl vinylformic acid, vinylformic acid, most preferably are vinylformic acid.
The invention provides a kind of method for preparing thickening material of the present invention: be characterised in that (a) with polyethers and methacrylic acid or vinylformic acid by the mixed in molar ratio between 1: 0.5～1: 6, (b) add acid catalyst, its amount is the 0.2-3% of polyethers, methacrylic acid or vinylformic acid and acid catalyst gross weight, (c) maintain the temperature at 90～180 ℃ and stir 1～6h, carry out esterification, copolymerization makes.
The present invention also further provides thickening material of the present invention has been used in liquid lotion.
The advantage of thickening material of the present invention and effect can be by following method detection validation: because of there is esterification in reaction process, so its acid number can reduce gradually, and also there is a polyreaction, so the oneself viscosity of product can constantly increase, so can come the detection reaction degree by acid number and the oneself viscosity of measuring product.Its final thickening properties can be measured by the obtaining liq liquid detergent.Generally can select following prescription test for use: linear alkyl benzene sulphonic acid: 4%, product of the present invention: 2%, 6501 (1: 1 type): 2%, NaCl:0.3% uses NaOH to transfer PH=7～8, adds water to 100%.Test condition: 25 ℃, the 3# rotor of use NDJ-II type rotational viscosimeter, rotating speed 30r/min.After tested, thickening material of the present invention has good thickening capabilities, be used to prepare the viscosity that the low-concentration liquid washing composition can enlarge markedly product, effectively reduce product cost, have good chelating ability simultaneously, metal ions such as the calcium in can complexing water, magnesium, copper, iron, promote washing effect, and have good washing, degreasing cooperative ability, improve other tensio-active agent cleaning functions, and can reduce the soapy feeling of liquid washing agent.In addition, the present invention also provides a kind of preparation method of single stage method synthetic thickening agent of easy, easy handling, does not use solvent, makes reaction be easy to control, and can be because of the solvent pollution products.
