Description
Technical Field
The invention belongs to the technical field of biology, and particularly relates to a water-in-oil composition with high water phase content and containing saccharides or acids, salts thereof or amino acids, and a preparation method thereof.
Background
Water-in-oil (W/O) emulsions are formed by mixing oil, water and an emulsifier. The morphology of the system is such that the water is dispersed in the oil in the form of small droplets. The aqueous phase is the internal or dispersed phase and the oil is the external or dispersion medium. In water-in-oil emulsions, the action of the emulsifier is critical to the formation and stability of the emulsion. The emulsifier molecule is generally composed of a nonpolar, oleophilic hydrocarbon chain part and a polar, hydrophilic group, and has the dual properties of hydrophilicity and lipophilicity. The addition of the emulsifier can greatly reduce the tension of an oil/water interface and form an interface film on the interface by adsorption, thereby ensuring the stability of the emulsion to a certain extent. The water-in-oil law is widely applied to scientific research, production and daily life, for example, in the research and production of skin care products and the like, the application of a water-in-oil system can often obtain satisfactory results.
At present, the water-in-oil system cosmetics series products on the market are commonly sunscreen cream, isolation cream and the like. In order to disperse the powder, high-content oil is usually added, the high-content oil easily causes heavy skin feel, stickiness and air impermeability, and consumers need to perform tedious makeup removing steps such as makeup removing and cleansing with a facial cream after using, otherwise pores are blocked, the phenomenon of large pores is caused, and the like, so that the product is not suitable for people with sensitive skin and oily skin. In addition, some skin care products of water-in-oil system are also on the market, but for the stability of the system, the proportion of the emulsifier and the oil phase is increased for most products, which causes the undesirable use experience of heavy texture, greasy skin feel, poor ductility and the like of the products. A further problem is that the water phase content of the existing water-in-oil products on the market is below 80% on average and not more than 90% at the most. Some products are easy to leak oil and even separate oil in high-temperature weather in order to pursue the water outlet effect and neglect the stability of the products. Moreover, the existing water-in-oil system product is relatively energy-consuming in preparation process, needs high-temperature heating to provide certain energy during preparation, and needs long-time rapid stirring and homogenization to achieve the effect of uniform material body.
In addition to the above problems, the existing water-in-oil type products also have common diseases of all skin care products, namely, some preservatives, bacteriostats and the like are added for long-time storage of the products. Cosmetics with excessive or improper preservatives can lead epidermal cells to develop immature and loose structure, so that the epidermal layer becomes thin, is easy to be stimulated by the outside and has reduced defense force; in addition, preservatives can damage cellular DNA, causing the skin to lose its elasticity and causing problems such as sagging and fine lines. The skin cells damaged by the preservative can be continuously defectively propagated to make the skin quality worse and worse, so that the skin care purpose is inverted, and the effect is opposite.

The emulsifier formulation, in mass fractions, is shown in table 1.
TABLE 1 different proportions of emulsifier components
The preparation process comprises the following steps:
the water phase raw materials are evenly mixed by a glass rod at the temperature of 25 ℃, and are equally divided into 5 parts for standby.
At 25 ℃, the emulsifier is uniformly mixed by using a glass rod, and then is uniformly mixed with the oil phase for later use.

And finally, placing the semi-finished product wrapped by the water in oil in a sterilization pot for moist heat sterilization at the temperature of 121 ℃ for 20min to obtain the water in oil type composition.
The water phase content of the water-in-oil composition prepared above was examined, and the results are shown in Table 2.
TABLE 2 Water phase content in Water-in-oil compositions with emulsifiers of different proportions
As can be seen from Table 2, the mixture of PEG/PPG-12/16 polydimethylsiloxane, polyglycerol-3 disiloxane polydimethylsiloxane and PPG-1-PEG-9 lauryl glycol ether is used as an emulsifier, the water phase content in the obtained composition is more than 90%, and the water phase content is the highest and the wrapped water phase content is 95.5% in the ratio of 4 (0.75% of PEG/PPG-12/16 polydimethylsiloxane, 0.25% of polyglycerol-3 disiloxane polydimethylsiloxane and 1% of PPG-1-PEG-9 lauryl glycol ether), so that the composition can be completely wrapped and is the optimal ratio.
Example 3
This example is based on the formulation 4 of example 2 and examined the effect of different emulsifiers on the water phase content of the water-in-oil composition. In this example, the components and preparation method were the same as in example 2, except that the emulsifier formulation was different from that of example 2. The emulsifier formulation of this example is shown in table 3.
TABLE 3 different emulsifier formulations
The water content of the water-in-oil compositions prepared according to formulations 7 to 15 was examined and the results are shown in Table 4.
TABLE 4 Water phase content in Water-in-oil compositions with emulsifiers of different proportions
It can be seen from table 4 that the use of a mixture of polydimethylsiloxane, polyglycerol-3 disiloxane polydimethylsiloxane and PPG-1-PEG-9 laureth as emulsifier is a fundamental guarantee of the high water content obtained with the composition, the three components being none at all.
Example 4
This example is to examine the influence of the rotation speed on the water-phase wrapping amount of the water-in-oil composition, and also examine the influence of the rotation speed on the stability, texture, viscosity, water-yielding rate, etc. of the resulting composition.
The formulation of this example was identical to formulation 4 of example 2, and the preparation was identical to that of example 2 except that the rotational speed was controlled. The specific contents are as follows:
this example prepares water-in-oil compositions in groups, controlling the stirring speed to be: 50r/min, 100r/min, 150r/min, 200r/min, 250r/min, 300r/min, 350 r/min, 400 r/min, 500 r/min, for a total of 9 levels as shown in Table 5. Each part of the water phase and the oil phase are added and mixed evenly, and the other part is added.
TABLE 5 Whole course unified rotation speed experimental design
After the preparation, the water phase content of the 9 water-in-oil compositions A to I was measured, and the texture, viscosity and water application rate of the prepared compositions were examined, and the results are shown in tables 6 and 7.
TABLE 6 influence of different rotation speeds on the water phase content of the water-in-oil composition under the condition of uniform rotation speed in the whole course
TABLE 7 influence of different rotation speeds on the texture, viscosity and water-in-oil composition and the speed of water application in case of uniform rotation speed throughout the process
As can be seen from tables 6 and 7, the rotation speed affects to some extent the degree of entrapment of the oil in the prepared composition relative to the aqueous phase. Specifically, at a low rotation speed of 50-100 r/min, the water phase cannot be completely wrapped by the oil phase, and the oil-water separation phenomenon is easy to occur. The rotating speed is more than 150r/min, the water phase wrapping degree in the composition reaches more than 90%, and the water phase can be completely wrapped when the rotating speed reaches 200r/min and more. However, when the rotation speed exceeds 300r/min, the viscosity of the obtained composition becomes high, the texture becomes thick and heavy, the composition is not easy to push away, and the water is slowly coated or does not directly flow out. The reason is that under the condition of low rotating speed, the water phase and the oil phase which are added firstly form a stable water-in-oil system, and then the added components are difficult to wrap; under the condition of high rotating speed, oil drops are too small in dispersion and too tight in wrapping with the water phase, so that the viscosity of the product is increased, the texture is thick, and the water is not easy to flow out when the oil drops are coated. Therefore, the comprehensive consideration is that the rotating speed is controlled to be 150-300 r/min, preferably 200-300 r/min, so that the water phase wrapping content in the composition is ensured, the viscosity of the composition is proper, and the composition is light, thin and moist, is easy to discharge water when being smeared, and is suitable for people with sensitive skin or dry skin.
Example 5
This example is to examine the effect of conditions of moist heat sterilization on the stability of water-in-oil compositions.
The formulation of this example was identical to the formulation 4 of example 2, and the preparation method was identical to that of example 2 except that the conditions for moist heat sterilization were controlled differently. After the sterilization, the texture state of the water-in-oil composition was checked, and it was observed whether or not it was different from that before the sterilization, and it was examined whether or not the number of colonies in the composition met the relevant regulations.
In this example, 3 parts of the wrapped water-in-oil type semi-finished composition were prepared by the above method, and placed in autoclave respectively, and the conditions of moist heat sterilization were controlled as follows:
a: the temperature is 105 ℃, the pressure is 0.0194Mpa, and the time is 1h;
b: the temperature is 115 ℃, the pressure is 0.0676Mpa, and the time is 30min;
c: the temperature is 121 deg.C, the pressure is 0.103Mpa, and the time is 20min.
The results are shown in Table 8.
TABLE 8 Effect of different Sterilization conditions on the stability of Water-in-oil compositions
As can be seen from Table 8, the water-in-oil composition of the present invention has stable water-in-oil system when sterilized at 121 deg.C, and can ensure the sterility and safety of the product without adding any antiseptic and bacteriostatic component.
Example 6
This example is to examine the compatibility of the saccharide or acid and its salt or amino acid component with other components in the water-in-oil composition of the present invention.
The formulation of the water-in-oil composition of this example was such that the saccharides or acids and their salts or amino acids contained in the aqueous phase of the water-in-oil composition of formulation 4 of example 2 were defined as specific functional ingredients, and the remaining components and the preparation method were the same as those of example 2. The functional components are divided into three combinations, which are respectively: 1) Ectoin and dipotassium glycyrrhizinate with the effect of relieving and repairing; 2) Niacinamide and arbutin with whitening and freckle removing effects; 3) The content of 3D salicylic acid PCA zinc and the like with acne removing and oil controlling effects is shown in Table 9. The amount of water phase wrapped in the prepared product, the texture, viscosity and compatibility with the functional materials were examined and the results are also shown in table 9.
TABLE 9 Effect of added functional materials on Water-in-oil compositions
As can be seen from Table 9, the added functional raw materials have no influence on the texture and viscosity of the product, and the added functional raw materials have good compatibility, and can be completely wrapped by the oil phase together with other material components in the water phase, so that the development of the water-in-oil type cosmetic product is facilitated, and the added value, the use value and the economic value of the product are improved.
Example 7
This example is to examine the stability of the water-in-oil composition of the invention. This example is a study of the stability of the water-in-oil composition prepared in example 2 and the water-in-oil composition with efficacy prepared in example 6. The investigation conditions are as follows: first, one part of each of the prepared water-in-oil compositions was stored at a constant temperature of 8 ℃ as a control sample, and the remaining part was divided into 4 parts, followed by the following treatments: 1) Freezing at-15 deg.C for one month; 2) Freezing at-15 deg.C, heating to 45 deg.C, thawing, and circulating for one month; 3) Storing at 45 deg.C for three months; 4) Centrifuging at 2000r/min for 30min. After the completion of each treatment method, the presence or absence of stratification, water discharge and oil bleeding of each water-in-oil composition was observed, and the microbial condition thereof was examined, and the results are shown in table 10.
