Method.
Background technology
Water-in-oil type (W/O) system refers to grease etc. as foreign minister or decentralized medium that hydroaropic substance is interior phase or dispersion
Phase, hydroaropic substance is dispersed in the system in oil in forms such as drops;It is relatively broad in products applications such as BB frosts, but open in formula
Send out and technique productions in, be frequently encountered the problem of dispensing viscosity stability, be mainly reflected between batch that the differences in viscosity opposite sex is big, resistance to
Situations such as viscosity B coefficent is obvious after heat is cold-resistant, quality risk is higher.Jing is analyzed, it is believed that be the rheology modifier product due to oil phase
Plant relative aqueous phase stream change modifying agent not enough to enrich, and it is strong without aqueous phase stream change modifying agent in terms of the effect of interior phase aggregation is prevented.
The content of the invention
The purpose of the present invention is to overcome above-mentioned technical problem, there is provided a kind of side of raising water-in-oil type creams viscosity stability

Compared to prior art, the method for the raising water-in-oil type creams viscosity stability that the present invention is provided is by described
Add hydrophilic smectites modifying agent and oil loving organic clay class modifying agent in water-in-oil type creams, can significantly carry
High water-in-oil type creams viscosity stability, prepared creams stable performance, rheological property is good.
Specific embodiment
With reference to embodiment, the present invention is described in further detail, but embodiments of the present invention not limited to this.
The method of the raising water-in-oil type creams viscosity stability that the present invention is provided is by the water-in-oil type creams
Add hydrophilic smectites modifying agent and oil loving organic clay class modifying agent, wherein the smectites modifying agent
Consumption accounts for the 0.01-5% of the water-in-oil type creams gross mass, and the consumption of the organic clay class modifying agent accounts for the Water-In-Oil
The 0.01-5% of type creams gross mass.
Embodiment 1-3, its formula is shown in Table 1.
Table 1
The smectites modifying agent is distinguished as the component of E phases, the organic clay class modifying agent as the component of A phases
Add in the preparation process of the water-in-oil type creams, the smectites modifying agent of wherein embodiment 1 is:Hectorite, it is organic
Clay class modifying agent is:Distearyl dimethylammonium hectorite;The smectites modifying agent of embodiment 2 is:Lithium magnesium silicate, it is organic glutinous
Great soil group modifying agent is:The bentonite of quaternary ammonium salt -18;The smectites modifying agent of embodiment 3 is:Bentonite, organic clay class is modified
Agent is:Distearyl dimethylammonium hectorite.Comparative example 1 only add organic clay class modifying agent distearyl dimethylammonium hectorite and
Without smectites modifying agent, comparative example 2 is only added smectites modifying agent hectorite and is modified without organic clay class
Agent.The preparation method of embodiment 1-3 and comparative example 1-2 is as follows:
Step S1, mill A phase each component high speed homogenizations 30min, is warming up to 80 DEG C, insulation;
Step S2, E phase is pre-mixed, and is warming up to 80 DEG C, high speed homogenization 20 minutes;
Step S3, B phases each component is put under agitation in E phases, high speed homogenization 2 minutes;
Step S4, under agitation E phases are slowly added into A phases, high speed homogenization 10 minutes;
Step S5, addition C phases, stirring is cooled to 40 DEG C, adds D phases, is stirred until homogeneous, and detection is qualified can to discharge.
Water-in-oil type creams viscosity stability is tested
By the creams of preparation be divided into three parts be individually positioned in -15 DEG C, 25 DEG C, carry out viscosity tracking and testing within 6 months at 45 DEG C.
Method of testing adopts BROOKFIELD DV2T RVT JO type digital display viscosity apparatus, in 04# rotors, 12rpm, carries out under the conditions of 25 DEG C
Test, concrete test result is shown in Table 2.
Table 2
From table 2 it can be seen that by adding hydrophilic smectites modifying agent and oil loving organic glutinous in creams
After great soil group modifying agent, at each temperature storage viscosity B coefficent is little, has good stability, and only adds hydrophilic smectites modifying agent
Or oil loving organic clay class modifying agent, then viscosity stability differ greatly, the viscosity error scope of comparative example 1 has exceeded
± 30%, even there is layering equistability exception in comparative example 2, and illustrate present invention offer adds parent in water-in-oil type creams
Aqueous smectites modifying agent and the method for oil loving organic clay class modifying agent is stablized to improving water-in-oil type creams
Property has very great help.
Compared to prior art, the method for the raising water-in-oil type creams viscosity stability that the present invention is provided is by described
Add hydrophilic smectites modifying agent and oil loving organic clay class modifying agent in water-in-oil type creams, can significantly carry
