Embodiment 1

[0033]

[0034]

[0035] Note: Phase A is the oil phase component and emulsifier of the water-in-oil pre-emulsion, phase B is the water phase component, and phase C is the oil phase component.

[0036] The steps for preparing the above-mentioned products are as follows:

[0037] 1. Prepare water-in-oil pre-emulsion at room temperature:

[0038] First add 5wt% WE 09 with 2wt% CT is mixed at room temperature and stirred evenly; then the water phase component (a mixture of water and glycerin) is added dropwise, and stirred continuously while adding to obtain a water-in-oil pre-emulsion.

[0039] 2. Mix the remaining oil phase component C evenly and heat to 70°C.

[0040] 3. Add the water-in-oil pre-emulsion to the oil phase components, stir slowly to disperse it evenly, keep the temperature of the mixture at 85°C, and keep stirring to make it evenly mixed.

[0041] 4. Injection mold at 80°C, cool to room temperature and place in -15°C refrigerator for 45 minutes to fo...

Embodiment 2

[0045]

[0046]

[0047] Note: Phase A is the oil phase component and emulsifier of the water-in-oil pre-emulsion, phase B is the water phase component, and phase C is the oil phase component.

[0048] The product of Example 2 was prepared according to the procedure of Example 1 using the components and amounts shown in the table above.

[0049] image 3 A magnified 400-fold photomicrograph of a thin layer of a high-moisture content lipstick with a water content of 30 wt% prepared for Example 2 applied to a glass slide. It can be seen from the photos that the interior of the lipstick sample is uniform, and the water phase is also uniformly distributed in the form of round particles.

Embodiment 3

[0051]

[0052]

[0053] Note: Phase A is the oil phase component and emulsifier of the water-in-oil pre-emulsion, phase B is the water phase component, phase C is the oil phase component, phase D is the pigment component, and phase E is the pearlescent component.

[0054] The steps for preparing the above-mentioned products are as follows:

[0055] 1. Prepare water-in-oil pre-emulsion at room temperature:

[0056] First add 4.4wt% WE 09 with 1.76wt% CT is mixed at room temperature and stirred evenly; then the water phase component (mixture of water and glycerin) is added dropwise, and stirred continuously while adding to keep the mixture in an emulsified state to obtain a water-in-oil pre-emulsion.

[0057] 2. Mix the remaining oil phase component C evenly and heat to 90°C.

[0058] 3. Add the water-in-oil pre-emulsion to the oil phase component C obtained in step 2, stir slowly to disperse it evenly, keep the temperature of the mixture at 85°C, and keep stirring t...

Abstract

The invention provides a lipstick prescription with high water content and a preparation method thereof. The lipstick prescription with high water content comprises the following components in percentage by weight: 1-10 weight percent of emulsifying agent, 1-30 weight percent of aqueous phase component and 69-98 weight percent of oil phase component. Pigment, a pearlized component or a water-soluble active component also can be added into the lipstick according to the requirements. The preparation method comprises the following steps: taking two or three mixtures of aliphatic acid polyglycerin ester, aliphatic acid ester and polyorganosiloxane modifier as the emulsifying agent; forming water-in-oil pre-emulsion; and then mixing the pre-emulsion and the oil phase component togther. The method effectively improves the water content in the lipstick. The lipstick with high water content has good shape stability in the processes of storage and use and does not have any phenomenon of rough surfaces or generated air holes. The prescription can reduce the lipstick cost, further add the water-soluble active component in an aqueous phase and bring bran-new experience to a consumer and can be widely used for a lip care product.

Description

technical field [0001] The invention relates to a lipstick with high water content and a preparation method thereof, belonging to the technical field of personal care products. Background technique [0002] Lip balms or lip balms usually come in a purely oil-based formula, and regular lip balms generally don't have added moisture. Since many of the skin or lip protective ingredients are water soluble, they are difficult to add to traditional lip balms or lip balms. Lip balms or lipsticks with a certain water content have appeared in the market at present, but their water content is generally still lower than 5wt%. [0003] Prior art patent CN1260166A reports water-in-oil cream products with a water content higher than 25 wt%, but these products cannot maintain a stable solid shape during storage and use, and cannot meet the needs of forming lipstick products with high water content. Contents of the invention [0004] In order to solve the problem of low water content and...
