Description
Technical Field
The invention belongs to the field of daily chemical products, and particularly relates to a detergent composition with suspending capability.
Background
The cleaning products commonly used are various in forms and various in types, and in order to improve the attractive appearance of the products and achieve certain effect purposes, a certain proportion of effect substances such as mica flakes, ZPT (zinc pyrithione), glycol distearate, air, organic silicon, friction agents and the like are suspended in the cleaning products, and when the cleaning products suspend the substances, the system is required to have certain suspending capacity, namely the system has a certain yield value, and the prior art is mainly realized by adding suspending agents.
The existing common suspending agents include gums, acrylic polymers, celluloses, silicates, derivatives and the like,
gum suspending agents commonly found in the prior art, such as acacia, gum arabic, guar gum, xanthan gum and the like;
the common acrylic polymers are two types of crosslinked polymers and copolymers, such as Carbopol and pemul series products of Lu Bo run company, and Salcare and Aculyn series products of Pasteur company, etc.; common celluloses include carboxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose, and the like; in addition, the silicate includes sodium magnesium lithium silicate, magnesium aluminum silicate, etc.
The gum and cellulose have high viscosity when used in the system, but have poor suspending ability and are not ion-resistant, and in addition, have certain decomposition problems and are easy to grow microorganisms.
The silicate suspending agent is usually composed of sodium magnesium lithium silicate and magnesium aluminum silicate, and forms a clamping house structure (Card House structure) by utilizing the action of surface charges, so that the silicate suspending agent has good shear thinning effect and good rheological property, but the silicate suspending agent has low yield value, poor suspending capability and great limitation in use.
The acrylic polymer is mainly carbomer and acrylic acid (ester) copolymer (such as Aquar SF-1) at present, the material has strong suspension capability, is generally much higher than natural polymer glue, has better rheological property and stronger ion resistance, but the suspension agent has a great problem that a polymer film formed by volatilizing water of a product during use has strong toughness, a pump head is easy to block in a pumping material, the pumping material cannot be normally used, and the transparency is greatly influenced by the pH value of a system.
In summary, most of the cleaning agents with good suspension effect in the prior art have higher system viscosity and have great influence on transparency, and finally, colloid is easy to form after volatilization, so that the use is influenced.

a. Standard apparent addition
b. Low surface activity additive amount
c. High apparent addition
1. The viscosity test method comprises the following steps: the test conditions were 25.+ -. 0.3 ℃ and 500mL of the test sample was carried out in a 500mL beaker using a model DV2TLVTJO viscometer available from Brookfield, and different rotors and rotational speeds were selected depending on the viscosity conditions.

1. the clean system charge was filled into a sample volumetric flask (care was taken to avoid air bubbles entering).
2. The turbidity data was click tested.
Experimental data shows that the detergent system prepared by adding the copolymer of the invention into the synthetic polymers of the groups A and F has lower viscosity and better transparency (generally, turbidity is lower than 200 and transparency is better); a has a very low viscosity compared to the class DE gum cellulose type suspending agents, and is still acceptable, although the turbidity is relatively high.
2. Suspending ability test
The invention changes a thermodynamic acceleration experiment to test the suspension stability of a system, and specifically comprises the following steps:
referring to fig. 1, a mixture of two types of particles (the weight ratio of the two types of particles is about 1:1, and the weight ratio of the two types of particles is 0.2-0.5%) is added into a transparent glass sample bottle with a height of 12cm and a volume of 50ml and containing a cleaning agent to be detected, the cleaning agent height is 10cm, a fringe picture is placed behind the glass sample bottle as a reference object, the distribution state of particles at the initial stage is recorded, then the mixture is placed into a 50-DEG constant temperature oven, the floating and sinking degree of the particles is observed, and the observation is compared with the investigation at the initial stage when the mixture is observed for 28 days according to the change of the particle height as a judgment basis.
Judgment standard: the system has no change of 10 minutes, slight decrease of 8 minutes, larger decrease of 5 minutes, serious decrease of 3 minutes and complete sinking of 0 minutes, and is considered to have better stability in a system with more than 5 minutes.
In addition to the variation in the dosage of suspending agent, this experimental example also investigated the effect of surfactant content on the thermodynamic stability of the system of the present invention and examples of higher and lower apparent addition are provided below.
Note that:
the particles 1 are selected fromPink Princess (average particle size 700 μm) DS54150.

The particle 2 was Puencelluloses green, 50/80 (average particle size 300 μm).
Production company: shanghai Pu En Biochemical technologies Co., ltd.
a. Thermodynamic stability data for example A and comparative examples
b. Thermodynamic stability data for low surface active additive examples
c. High apparent addition example thermodynamic stability data
The experimental data of the groups show that at low surface activity content, the polymer still has better transparency, lower viscosity and better suspending capability in the pH range of the system.
Example group F1, with increased high surface active content (about 30% total surfactant), was tested for viscosity and clarity at pH 4, 7, 10 by adding a series of effective amounts of the present polymer (0.6% 0.9%1.2%1.8%3.0%, respectively).
From the experimental data, it can be seen that the polymer suspending agent has good stability at specific content and pH relative to the fibers and gums, while the copolymer of the present invention has better stability in the cleaning system at higher addition compared to the same polymer BCF group, better than that of the F group, and inferior to that of the C and B groups.
Meanwhile, the experimental example also provides an embodiment in which air is used as a suspended matter:
example G (suspended matter is air):
example G preparation method:
(1) Adding water and a suspending agent at normal temperature, and stirring and dissolving uniformly;
(2) Sequentially adding surfactant, heating to 80-85 deg.C, and stirring to dissolve uniformly;
(3) Cooling to normal temperature, adding antiseptic, and stirring;
(4) The air injection process comprises the following steps: connecting a rubber hose with a syringe, placing the other end of the rubber hose at the bottom of the beaker, slowly injecting air with a required volume in a stirring state, and carefully controlling the injection speed to form relatively uniform air bubbles in the combined structure;
(5) The preparation of the examples was completed by adjusting to the target pH with a pH adjustor.
Experiments show that when the copolymer of the invention reaches a certain addition amount, air bubbles can be stably suspended (the required suspension force and density difference (suspended matter and suspended matter) of suspended matters in a composition system are in direct proportion, and generally, the density difference of air and a material body is the limit condition in the field).
Note that: in example G, 10% Teaxpon N70, 6% TEGO BETAIN CK KB AS, 1.2% Miranol ultra L-32 and 0.5% Teaxpon N70 were added in mass percent; in addition, a small amount of preservative and a pH adjustor for adjusting the pH to a target pH are added.
3. Curing gel test
The test is carried out in three groups of experiments, specifically:
a. foam pump test the performance of a cleaning system containing a suspending agent in a foam pump head wrapper was tested rapidly.
The test steps are as follows:
1. 100ml of the cleaning composition is filled into a pressure pump, and the air in the pump is discharged by pressing until the material body foams out;
2. five presses, compare the foaming of the cleaning composition;
3. putting the mixture into a 50-DEG oven to bake for 48 hours, enabling the moisture in the pump head to volatilize rapidly, accelerating simulation of actual use conditions, taking out, continuing pressing for five times, and evaluating foam conditions;
4. continuously putting the mixture into a 50-DEG oven for baking for 48 hours after the use is finished;
5. taking out the test of pressing for five times, and evaluating the foam condition;
6. the cycle continues.
The foam conditions herein were evaluated mainly for three performance indicators, as compared to a blank without suspending agent.
The first index, foam extrusion smoothness, is expressed by 5 minutes to indicate that the press is normal 5, 4 to indicate that a little more force is needed, 3 to indicate that a larger force 2 is needed and a larger force 1 is needed to be completely blocked.
The second index, the amount of extruded foam, is expressed by 5 minutes, the 5 foam amount is normal 4 foam amount slightly less, the 3 foam amount is obviously reduced by 2 little foam 1 has no foam.
Index three, uniformity of the extruded foam, expressed in 5 minutes, was slightly non-uniform 5 normal 4, significantly non-uniform 3, very non-uniform 2, and completely non-uniform 1.
The above experimental comparison shows that when the cleaner composition added with the copolymer of the invention is used in a pump head packing material, the foam is easier to squeeze compared with other schemes, the formed foam is more uniform, and jelly can not be formed to block the pump head after a plurality of times of drying.
Note that: to prevent clogging of the pump head with particulate matter, the system was cleaned without particulate matter in this test, and the system was tested for pH at 4, 7, and 10.
Note that: the foam pump for the test adopts a common market packing material, and is an R700-40/410A-AA pump head packing material produced by Shanzhi Rong Sen pump industry Co.
b. Film forming puncture test
The test uses a film puller and texture analyzer to perform a film penetration test on a cleaning composition containing a polymer.
Because the low concentration of suspending agent is difficult to form a film and the puncture effect is not ideal, three groups of DEF completely fail, an embodiment of suspending agent with higher concentration is adopted and compared with a comparative example with high concentration to explore the film forming puncture performance of the two.
Composition ratio of each example and comparative example
The experimental steps are as follows:
s1, preparing a plastic soft film, and clamping the film onto a film puller;
s2, placing a wet film preparation device close to the left push rod, and placing the required distance downwards (the wet film preparation device is 400 mu m according to the thickness of the film);
s3, weighing 6g of the composition containing the cleaning agent, and uniformly distributing the sample close to the wet film preparation device;
s4, starting a film making device, and pulling out a film with the thickness of 7.5 cm or so at the speed of 1 in/sec;
s5, loosening the clamp, and transferring the prepared film and the plastic film into a flat plate together, and baking at 80 ℃ for 2 hours;
s6, taking out and placing in an oven with the temperature of 25 ℃ and 55%RH again for cooling for 1 hour;
s7, a stainless steel needle type probe with a diameter of 1.2mm and a flat type probe with a width of 9.2mm are respectively used for downward running at a speed of 1.5mm/sec, and after the probe is contacted with a film, puncture test is carried out at a speed of 2mm/sec with a force of 5 g.
In the step 3, the samples are distributed according to the width of the film drawing device, and the samples are distributed at the position within the width of the Yu Lamo device.
Referring to fig. 2, it can be seen that the film formed of AA1 is more likely to break than the other two, and on the other hand demonstrates that the copolymer of the present invention has better film forming properties in detergent compositions and better effectiveness in foam pump packages.
Note that:
the plastic soft film can be cut by a common plastic file bag;
film drawing device: BYK company, model: byko-drive;
wet film preparation: shanghai modern environmental engineering technologies Co., ltd., model: SZQ.
The 5g in step 7 is the unit of lancing apparatus, equivalent to a pressure of 0.05N.
c. Shear thinning ability test
In order to rapidly test the use performance of a cleaning system containing a suspending agent in a spray pump head packing material, the test adopts a spray test and simplifies the test method.
The testing steps are as follows:
s1, filling 100ml of cleaning composition into a pressure pump, and pressing and discharging air in the pump until a material body is sprayed out;
s2, pressing for five times, and comparing the spraying condition of the cleaning composition.
The test evaluates mainly two properties, as a control with a blank without suspending agent.
Performance one and evaluation criteria: the smoothness of spray extrusion is indicated by 5 minutes for 5 for normal pressing, 4 for slightly more force, 3 for greater force 2 for greater force 1 for complete blockage.
Performance two and evaluation criteria: extrusion spray uniformity, expressed in 5 minutes, is 5 normal 4 slightly uneven, 3 significantly uneven 2 very uneven 1 completely uneven.
Note that: the spray pump adopts a common packing material in the market, R600-20/410B-CAA spray pump head packing material produced by Shanzhi Rong Sen pump industry Co., ltd, and in order to prevent particulate matters from blocking the pump head, no particulate matters are added into the cleaning system material in the test, and the conditions of pH values of 4, 7 and 10 are tested.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
