Description

Technical Field

[0001] This invention relates to the field of cosmetic technology, and in particular to a lip gloss film-forming agent and its preparation method. Background Technology

[0002] Lip gloss is a cosmetic product for the lips, applied directly to the lips or over lipstick. Its primary purpose is to give the lips a glossy finish, and sometimes it adds a small amount of color. It is typically in liquid or soft solid form, ranging from translucent to solid opacity, and can have matte, shimmer, shine, and / or metallic textures.

[0003] Film-forming lip glosses typically refer to those that, after application, form a thin film on the lips over time. This film makes the lip makeup look more glossy, often achieving a glass-like lip effect, and is relatively less prone to fading and transferring. For example, some mirror-finish lip glosses, after forming a film, can maintain their color well even after drinking water or slight contact. However, current film-forming agents lack sufficient gloss and have relatively poor abrasion resistance.

[0004] Therefore, how to provide a lip gloss film-forming agent with high refractive index and abrasion resistance is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In response to the aforementioned research status and existing problems, this invention provides a lip gloss film-forming agent and its preparation method. This invention uses a water glass process to produce silicone resin, introducing alkyl (C3~C20) and phenyl groups into the traditional silicone resin, which greatly improves the film-forming properties of the new silicone resin. Furthermore, the water glass resin has a large molecular weight and high rigidity, the introduction of phenyl groups provides high refractive properties, and the alkyl groups provide the softness of organic groups. Through testing, the film-forming properties, adhesion, and flexibility are significantly improved.

[0006] One objective of this invention is to provide a lip gloss film-forming agent with the following chemical formula:

[0007] ;

[0008] Where R=C n H 2n+1 The n is a positive integer.

[0009] Preferably, it includes: component A, component B, and component C, wherein, by mass ratio, component A comprises water:acid:alcohol = 1:(0.2-1.3):(0.2-1.3).

[0010] The B component comprises: water glass:water = 1:1 to 1:5;

[0011] The C component comprises: capping agent: alkylsilane: phenylsilane = 1: (0.1-0.3): (0.1-0.3).

[0012] Preferably, the acid is selected from concentrated hydrochloric acid, concentrated sulfuric acid, or trifluoromethanesulfonic acid;

[0013] The alcohol is selected from methanol, ethanol, isopropanol or n-butanol.

[0014] Preferably, the capping agent is selected from trimethylchlorosilane and hexamethyldisiloxane;

[0015] The alkylsilane is selected from propyltrimethoxysilane, propyltriethoxysilane, octyltrimethoxysilane, octyltriethoxysilane, lauryltrimethoxysilane, or lauryltriethoxysilane;

[0016] The phenylsilane is selected from methylphenyldimethoxysilane, methylphenyldiethoxysilane, diphenyldimethoxysilane, diphenyldiethoxysilane, phenyltrimethoxysilane, or phenyltriethoxysilane.

[0017] The second objective of this invention is to provide a method for preparing a lip gloss film-forming agent, comprising the following steps:

[0018] 1) Add component A into the reactor according to the mass ratio, raise the temperature and maintain it at 20±5℃, and stir for 10-30 min;

[0019] 2) Add component B into the reactor according to the mass ratio, stabilize the temperature inside the reactor at 30±5℃, and stir for 10-30 minutes;

[0020] 3) Add component C into the reactor according to the mass ratio, stabilize the temperature inside the reactor at 50±5℃, and stir for 2-4 hours;

[0021] 4) Cool to 20±5℃, add the extractant, stir for 0.5-1h and then stop stirring. Transfer to a separatory vessel and let stand to separate the contents.

[0022] 5) Take the organic solution layer, wash it with hot water at 70±5℃ for 10-30 minutes, repeat the washing until pH=7, and stir;

[0023] 6) Heat to 100-150℃ and distill off the extractant to obtain solid resin.

[0024] Preferably, the stirring speed in the preparation method is controlled at 50-200 r / min.

[0025] Preferably, the repeated washing is performed 3-5 times.

[0026] Preferably, the extractant is selected from isododecane, isohexadecane, or hexamethyldisiloxane.

[0027] In summary, compared with the prior art, the present invention has at least the following technical advantages:

[0028] Given that traditional film-forming agents are hard and brittle when forming lip gloss films due to the lack of organic functional groups, this invention aims to overturn the structure of traditional film-forming agents by introducing more organic functional groups, such as phenyl and high alkyl groups, and changing the silicone resin structure to MDQ or MTQ to form a better branched structure, which is more branched and has better softness than Dow1640.

[0029] The MQ type silicone resin, composed of water glass and end-capping agent, has a traditional structure. The prepared silicone resin is hard and brittle when forming a lip gloss film due to the lack of organic functional groups (Wacker 803, a comparative case later). However, by introducing more organic functional groups, such as phenyl and high alkyl groups, the structure of the MQ silicone resin can be changed to MDQ or MTQ, forming a better branched structure that is more branched and has better softness than Dow1640.
