Problems solved by technology

Although there are also some solvent-based products in the prior art that can emulsify after being washed with water, their decontamination mainly uses oily components as solvents to dissolve the dirt on the skin, so the decontamination ability is weak, and the solvent-based products Product packaging costs are high

Embodiment 1-5

[0036] The formulations of Examples 1-5 are shown in Table 1 below.

[0037] Table 1

[0038]

[0039] The oil-in-water emulsions of Examples 1-5 were prepared according to the following steps:

[0040] 1). Dissolve glycerin and chloroacetamide preservatives in water to form a water phase, and then add an oil-in-water emulsifier (that is, cetearyl polyoxyethylene (15) ether and glyceryl stearate) and detergents (i.e., cocamidopropyl betaine, octyl / decylamidopropyl betaine, disodium lauryl sulfosuccinate, N-cocamidoethyl-N-hydroxyethyl Aminodiacetate disodium or N-cocoamidoethyl-N-hydroxyethylaminoacetate) were added to the entire water phase obtained by each formula, and heated to 80 ° C to dissolve to obtain a homogeneous water phase mixture, That is, phase B;

[0041] 2). Mix ethylhexyl palmitate and di-ethylhexyl carbonate to obtain the oil phase, that is, phase A, and then add phase A to phase B obtained in step 1) within 5 minutes under stirring at 800rpm (that is,...

Embodiment 6

[0053] The formulation of Example 6 is shown in Table 2 below.

[0054] Table 2

[0055]

[0056] The oil-in-water emulsion of Example 6 was prepared according to the following steps:

[0057] 1). Dissolve glycerin, xanthan gum and chloroacetamide preservatives in water to form a water phase, then add the oil-in-water emulsifier and detergent into the resulting entire water phase, and heat to 80°C to dissolve to obtain a homogeneous The aqueous phase mixture of the phase, that is, the B phase;

[0058] 2). Mix ethylhexyl palmitate and di-ethylhexyl carbonate to obtain the oil phase, that is, phase A, and then add phase A to phase B obtained in step 1) within 3 minutes under stirring at 800rpm (that is, adding an oil phase accounting for 18wt.% of the total amount of the emulsion per minute), the entire system remains in a uniform emulsified state throughout the addition process; and

[0059] 3). After all the oil phase A is added, increase the stirring speed to 1000rpm f...

Embodiment 7

[0063] The formulation of Example 7 is shown in Table 3 below.

[0064] table 3

[0065]

[0066] The oil-in-water emulsion of Example 7 was prepared according to the following steps:

[0067] 1). Dissolve the chloroacetamide preservative in water to form a water phase, then add the oil-in-water emulsifier and detergent into the resulting entire water phase, and heat to 80°C to dissolve to obtain a homogeneous water phase mixture, That is, phase B;

[0068] 2). Mix ethylhexyl palmitate and di-ethylhexyl carbonate to obtain the oil phase, that is, phase A, and then add phase A to phase B obtained in step 1) within 15 minutes under stirring at 600 rpm (that is, add the oil phase that accounts for 5.7wt.% of the total amount of emulsion per minute), the whole system maintains a uniform emulsified state throughout the addition process; and

[0069] 3). After all the oil phase A is added, turn on the homogenizer for homogenization to obtain the oil-in-water emulsion product, na...

Abstract

The invention relates to an oil-in-water emulsion with high content of oil phase and cleaning effect, which comprises 45-90% by weight of oil phase, 5-45% by weight of water phase, 3-10% by weight of emulsifier component and 2-10% by weight of detergent component with the HLB value of being larger than 18 based on the total weight of the emulsion, wherein the HLB value of the emulsifier component is 8-18, and the compound HLB value is 10-15. In addition, the invention further relates to a preparation method and a use of the emulsion. The oil-in-water emulsion has storage stability and can release skin-moisturizing grease during smearing, be changed into the emulsion after being leached with water, be easy to flush clean and leave non-greasy skin feeling on skin, so that the oil-in-water emulsion can be widely used in products for personal nursing and making up.

Description

technical field [0001] The invention relates to an oil-in-water emulsion with a high oil phase content and a cleaning effect, a preparation method and application of the emulsion, and the emulsion can be widely used in the cosmetic industry. Background technique [0002] Existing makeup remover or cleansing products for skin on the market generally have three types: surfactant type mainly based on soap base or other surfactants, solvent type mainly based on solvents such as oily components, moisturizers, alcohol and water, etc. And the oil-in-water emulsified type between the former two. The first type of surfactant type has strong degreasing power, the second type of solvent type has relatively high requirements for packaging, and the third type of oil-in-water emulsified type has a creamy appearance, is convenient to use, and can release oil quickly after use. Functions such as removing makeup. However, the general oil-in-water emulsified type has a low oil content and h...
