Technical field
The present invention relates to technical field of skin care, and in particular to a kind of side for improving water-in-oil type creams viscosity stability
Method.
Background technique
Water-in-oil type (W/O) system refers to grease etc. that for foreign minister or decentralized medium, hydroaropic substance is interior phase or dispersion
Phase, hydroaropic substance disperse system in the oil in the form of drop etc.;It is relatively broad in products applications such as BB frosts, but opened in formula
In hair and technique production, the problem of being frequently encountered dispensing viscosity stability, the differences in viscosity opposite sex is big, resistance between being mainly reflected in batch
Situations such as viscosity change is obvious after heat is cold-resistant, quality risk is higher.Through analyzing, it is believed that be the rheology modifier product due to oily phase
The opposite water phase rheology modifier of kind is not abundant enough, and strong without water phase rheology modifier in terms of the effect for preventing interior phase aggregation.

High water-in-oil type creams viscosity stability, prepared creams performance are stablized, and rheological property is good.
Specific embodiment
Below with reference to embodiment, the present invention is described in further detail, and embodiments of the present invention are not limited thereto.
The method provided by the invention for improving water-in-oil type creams viscosity stability passes through in the water-in-oil type creams
Hydrophilic smectites modifying agent and lipophilic organic clay class modifying agent are added, wherein the smectites modifying agent
Dosage accounts for the 0.01-5% of the water-in-oil type creams gross mass, and the dosage 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, formula are shown in Table 1.
Table 1
The smectites modifying agent is distinguished as the component of E phase, the organic clay class modifying agent as the component of A phase
It is added in the preparation process of the water-in-oil type creams, wherein the smectites modifying agent of embodiment 1 are as follows: hectorite, it is organic
Clay class modifying agent are as follows: distearyl dimethylammonium hectorite;The smectites modifying agent of embodiment 2 are as follows: lithium magnesium silicate, it is organic glutinous
Great soil group modifying agent are as follows: -18 bentonite of quaternary ammonium salt;The smectites modifying agent of embodiment 3 are as follows: bentonite, organic clay class are modified
Agent are as follows: distearyl dimethylammonium hectorite.Comparative example 1 only add organic clay class modifying agent distearyl dimethylammonium hectorite and
Smectites modifying agent is not added, and it is modified without adding organic clay class that comparative example 2 only adds smectites modifying agent hectorite
Agent.Embodiment 1-3 and comparative example 1-2's the preparation method is as follows:
Step S1, A phase each component high speed homogenization is milled 30min, is warming up to 80 DEG C, heat preservation;
Step S2, E phase is pre-mixed, and is warming up to 80 DEG C, high speed homogenization 20 minutes;
Step S3, B phase each component is put under stiring in E phase, high speed homogenization 2 minutes;
Step S4, E phase is slowly added to A phase under stiring, high speed homogenization 10 minutes;
Step S5, C phase is added, stirring is cooled to 40 DEG C, and D phase is added, is stirred until homogeneous, and detection qualification can discharge.
The test of water-in-oil type creams viscosity stability
The creams of preparation are divided into three parts and are individually positioned in 6 months progress viscosity tracking and testings at -15 DEG C, 25 DEG C, 45 DEG C.
Test method uses BROOKFIELD DV2T RVT JO type digital display viscosity apparatus, and in 04# rotor, 12rpm is carried out under the conditions of 25 DEG C
Test, specific test result are shown in Table 2.
Table 2
From table 2 it can be seen that by adding hydrophilic smectites modifying agent and lipophilic organic glutinous in creams
After great soil group modifying agent, storage viscosity change is small at each temperature, has good stability, and only adds hydrophilic smectites modifying agent
Or lipophilic organic clay class modifying agent, then viscosity stability differs greatly, and the viscosity error range of comparative example 1 has exceeded
± 30%, even there is layering equistability exception in comparative example 2, illustrates the addition parent provided by the invention in water-in-oil type creams
The method of aqueous smectites modifying agent and lipophilic organic clay class modifying agent is to the stabilization for improving water-in-oil type creams
Property has very great help.
Compared to the prior art, the method provided by the invention for improving water-in-oil type creams viscosity stability passes through described
