Problems solved by technology

However, lip products such as lipsticks are generally pure oily systems, and the water phase and oil are incompatible with each other, which hinders the application of spirulina extract in lip products
In addition, lip products such as lipstick often need to undergo high-temperature operations such as heating and secondary filling during the production process, while spirulina extract is not resistant to high temperature for a long time, and is easy to deactivate and flocculate under long-term high temperature, so that "sweating" in
This further limits the use of spirulina in lip products

[0036] Provide a kind of lip cosmetics containing spirulina extract, the ratio of each component is as shown in table 1 below:

[0037] Table 1. Composition ratio of lip cosmetics

[0038]

[0039]

[0040] The preparation method of this lip cosmetic is as follows:

[0041] (1) Weigh white oil, ethylhexyl palmitate, polyisobutylene, octyldodecanol, synthetic wax, C12-15 alcohol benzoate, microcrystalline wax, and turpentine extract according to the dosage of the above formula and add In the reaction pot, turn on the heating equipment and stir slowly, control the temperature at 95-100°C, wait until the wax in the system is completely dissolved to form phase A, keep it warm for 10 minutes, and turn on the cooling device;

[0042] (2) Water, sunflower wax, jojoba wax, green wattle wax, polyglycerol-3, polyglyceryl-6 distearate, jojoba ester, polyglyceryl-3 beescerate, cetacean Weigh the wax alcohol and Spirulina spirulina extract into another reaction pot, heat to 70-75°C...

Embodiment 2

[0046] Comparative Experiment

[0047] According to the method in the combination and ratio reference example 1 in the following table 2, the preparation of each comparative example is carried out:

[0048] Table 2. Comparative experiment formula (wt%)

[0049]

[0050]

[0051] Among them, Span-60 (Sorbitan Stearate); ABIL EM 90 (Cetyl PEG / PPG-10 / 1 Dimethicone); BAREMUL ML (Isosteareth-20, Sorbitol Tansequioleate); ISOLAN GPS (polyglyceryl-4 diisostearate / polyhydroxystearate / sebacate). The ratio of sunflower wax, jojoba wax, green wattle wax and polyglycerol-3 refers to Acticire wax. Polyglyceryl-6 distearate, jojoba ester, polyglyceryl-3 mescelic acid ester, cetyl alcohol refer to Mellifera MB charm bee.

[0052] Store under four conditions of normal temperature, high temperature (45°C), low temperature (-8°C), and light, respectively, and observe the stability of the product. After three months of testing, the results are shown in Table 3, Table 4 and Figure 1 to ...

Abstract

The invention provides a lip cosmetic containing spirulina extract and a preparation method thereof. The lip cosmetic comprises the following components in percentage by weight: oil phase matrix 67-91.1 wt%, algae extract 0.5-2 wt%, and a composite emulsifier 4-8 wt%; wherein the composite emulsifier comprises a first emulsifier and a second emulsifier, wherein the first emulsifier comprises sunflower wax, jojoba wax and acacia decuttens flower wax; and the second emulsifier comprises polyglycerol-6 distearate, jojoba ester, polyglycerol-3 beesmate and cetyl alcohol. The sunflower wax, jojobawax and acacia decuttens flower wax are compounded with the polyglycerol-6 distearate, jojoba ester, polyglycerol-3 beesmate and cetyl alcohol, and can effectively increase water transfer ratio and reduce water transfer temperature, thereby reducing occurrence of "sweating" during a molding process. Moreover, the compounding of the emulsifiers can effectively avoid flocculation of the algae extract and ensure activity of the extract.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to lip cosmetics containing spirulina extract and a preparation method thereof. Background technique [0002] Lipstick is a necessity in our life, it can keep our lips not chapped, long-lasting moisturizing and long-term water-locking effect. The basic formula of traditional lipsticks is a wax-based oil system, which mainly uses oil to moisturize the lips and lock in moisture, so that the lips are not dry and have a supple and elastic effect. With the improvement of living standards, people have higher and higher requirements for the efficacy of lipsticks, and some functional ingredients will gradually be added to lipsticks. However, the active substances added to lipsticks are generally oil-soluble or oil-dispersed ingredients, and many effective water-soluble ingredients cannot be added to lip products due to oil-water immiscibility and high temperature resistance and easy inac...
