Description

Durable liquid foundation composition

Technical Field

The invention relates to the technical field of cosmetics, in particular to a durable foundation liquid composition.

Background

Currently, consumer performance requirements for liquid foundation compositions include, but are not limited to, providing sun protection, good color intensity, good color retention, water resistance, and/or perspiration resistance, and emulsifiers are typically used to provide that good skin feel of the liquid foundation composition. The colorants in prior liquid foundation compositions are easily transferred to clothes or towels. In order to solve the technical problems, the prior art is to add a film-forming agent into the foundation liquid composition, but the addition of the film-forming agent can cause high viscosity of the foundation liquid composition and make the foundation liquid composition difficult to spread when being applied, thus damaging good skin feel. If a film former is added to the foundation composition to achieve good skin feel, the film former will not successfully retain the actives or color of the foundation composition on the skin after contact with moisture or oil. It is therefore a technical challenge how to make a liquid foundation composition that provides good color strength and good color retention even after contact with moisture or oil.

In addition to the above-mentioned technical problems, the existing liquid foundation compositions have the following drawbacks:

1. the makeup effect is not lasting, the makeup is easy to remove, and the condition of makeup or removal is easily caused after oil or sweat appears on the face;

2. the foundation liquid composition which is declared to be moisturizing and rich in color on the market at present has a weak effect on resisting darkness.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a durable foundation liquid composition.

The term "anti-darkening" is defined as the color maintenance time of a liquid foundation composition, and when used in the present invention, the specific evaluation criteria for "anti-darkening" are: before sample loading, instant, 3h, 5h and 8h, using Visia 7 to shoot, and analyzing the variation values of skin brightness difference (delta L) and skin color Individual Type Angle (ITA) of the photos corresponding to the sample loading, instant, 3h, 5h and 8h before sample loading

The present invention relates to a long-lasting liquid foundation composition comprising an oil-dispersible film former component; a liquid oil component; an emulsifier component; thickener component: and one or more colorants.

More specifically, the durable liquid foundation composition consists of the following components in percentage by mass:

liquid oil: 10 to 35 percent;

film-forming agent: 0.5-10%;

emulsifier: 0.5-10%;

thickening agent: 0.2-4%;

colorant: 5 to 20 percent.

Preferably, the durable foundation fluid composition consists of the following components in percentage by mass:

liquid oil: 20 to 35 percent;

film-forming agent: 5 to 8 percent;

emulsifier: 4 to 7 percent;

thickening agent: 0.5-2%;

colorant: 10 to 15 percent.

Wherein the liquid oil is one or more of cyclopentadimethylsiloxane, polydimethylsiloxane, phenyl trimethicone, C20-24 alkyl polydimethylsiloxane and stearyl polydimethylsiloxane.

Wherein the film forming agent is silicone resin with film forming effect. The requirements of the foundation fluid composition for the film forming agent at least comprise the following steps: has good skin feel; film-forming agents contact moisture or oil after film formation requires successful retention of the actives or color of the foundation composition on the skin, while silicone resins having a film-forming effect are selected as film-forming agents based on cost considerations. Since the film-forming agent is required to be uniformly dispersed in the foundation composition, the mass percentage of the liquid oil in the foundation composition is determined based on the mass percentage of the film-forming agent in the foundation composition. The inventor finds out through experiments that: if the mass percentage of the film forming agent in the foundation liquid composition is less than 0.5%, the film forming effect of the foundation liquid composition is poor; if the mass percentage of the liquid oil in the liquid foundation composition is lower than 10%, the corresponding film forming agent and the corresponding coloring agent are unevenly dispersed in the liquid foundation composition; if the mass percentage of the film forming agent in the foundation liquid composition is higher than 10%, the problems of poor smearing, heavy stuffiness and the like of the foundation liquid composition are easily caused; if the mass percentage of the liquid oil in the liquid foundation composition is higher than 35 percent, the viscous feeling of the liquid foundation composition is easily too strong; if the mass percent of the film forming agent in the foundation liquid composition and the mass percent of the liquid oil in the foundation liquid composition are not reasonably matched, the foundation liquid composition system is easy to be unstable.

Preferably, the film forming agent is trimethylsiloxysilicate, the trimethylsiloxysilicate is an oil-soluble film forming agent with strong hydrophobicity and strong adhesion to powder, and the film forming agent has good water resistance and friction resistance when used in the foundation fluid composition and can effectively reduce toner migration; when the film forming agent is trimethylsiloxy silicate, the silicon alkoxy silicate is preferably dispersed in high-volatility liquid oil such as cyclopentadimethylsiloxane, so that the film forming speed can be increased in the coating process, and the effect of quick makeup can be achieved.

Wherein the emulsifier is polyether modified organosilicon emulsifier. The foundation liquid composition is compounded by adding the polyether modified organic silicon emulsifier and the silicon resin, and the polyether modified organic silicon emulsifier and the silicon resin have a synergistic effect, so that a film formed by the foundation liquid composition can tightly lock a coloring agent, and simultaneously has double effects of water resistance and oil resistance, thereby improving the migration resistance of the foundation liquid composition. The inventor finds out through experiments that: the mass percentage of the emulsifier in the foundation liquid composition and the mass percentage of the film-forming agent in the foundation liquid composition have a large influence on the makeup-holding effect, the mass percentage range of the film-forming agent in the foundation liquid composition is 0.5-10%, so that the mass percentage range of the emulsifier in the foundation liquid composition needs to be controlled to be 0.5-10%, and when the film-forming agent and the emulsifier are in the proportion and the addition amount, a water-resistant and oil-resistant double-layer protective film is better formed, so that the makeup-holding effect is greatly improved.

Preferably, the emulsifier is PEG/PPG-18/18 polydimethylsiloxane. The PEG/PPG-18/18 polydimethylsiloxane has a certain thickening effect and improves the stability of the foundation fluid composition to a certain extent. In addition, during the smearing process of the foundation liquid composition, the PEG/PPG-18/18 polydimethylsiloxane can form a dense and skin-attached reticular film to firmly lock the coloring agent on the film, and the PEG/PPG-18/18 polydimethylsiloxane has the hydrophobic characteristic, so that the formed film has a good water-resistant effect, and the removal of makeup caused by contact with moisture is reduced.

Wherein the thickening agent is organically treated bentonite. The organically treated bentonite can improve the stability of a foundation liquid composition system, and the organically treated bentonite can enable the coloring agent to be better attached to the skin to fill fine lines, and meanwhile, the skin attaching performance during smearing can be improved, the floating powder phenomenon is avoided, good concealing force is kept, and the natural naked makeup effect is not lost.

Preferably, the thickener is disteardimonium hectorite.

Wherein the colorant is compounded by triethoxycaprylylsilane and titanium dioxide, and the mass percent of the titanium dioxide is not less than 90%. Titanium dioxide is a toner, triethoxyoctylsilane can modify a titanium dioxide coating, the titanium dioxide is dispersed in a liquid composition system of the foundation, the triethoxyoctylsilane is added, and the triethoxyoctylsilane is attached to the surface of the titanium dioxide to form a layer of organic film through heterogeneous surface film forming effect and surface chemical bonding effect, so that the titanium dioxide obtains hydrophobic property. And after the triethoxyoctylsilane and the titanium dioxide are compounded, the skin-sticking property and the skin feeling of the titanium dioxide can be improved. In actual use, the foundation liquid composition provided by the invention can also select other pigments according to specific color requirements.

The lasting foundation liquid composition provided by the invention has good makeup holding effect and anti-darkness effect, has strong texture and high fineness, does not have the phenomena of makeup removal, oil bleeding, toner aggregation and the like after being smeared, and has excellent makeup effect. The film formed by coating the foundation liquid composition can tightly lock the colorant and has double effects of water resistance and oil resistance, thereby improving the migration resistance of the foundation liquid composition.

The following description is made with reference to specific embodiments.

the balance being solvents and other additives.

Wherein the solvent is one or more of glycerol, propylene glycol, dipropylene glycol, butanediol, polyethylene glycol, ethylhexyl glycerol, sorbitol, hexanediol, and pentanediol.

Wherein the liquid oil is cyclopentadecyldimethyl siloxane and polydimethylsiloxane according to the mass ratio of 1: 2, compounding; the film forming agent is trimethylsiloxy silicate; the emulsifier is PEG/PPG-18/18 polydimethylsiloxane; the thickener is disteardimonium hectorite; the colorant is triethoxyoctylsilane and titanium dioxide in a mass ratio of 1: 85 compounding

The liquid foundation compositions provided in this example can be prepared using techniques and methods well known in the art. Generally, all the adjunct ingredients such as thickeners, chelating agents, hydrophilic skin adhesion promoters and/or oil soluble actives are placed in the main vessel, added to the solvent, mixed until homogeneous and heated to about 80 ℃. Oil soluble ingredients such as solvents, emollients, emulsifiers, emulsion stabilizers, preservatives, hydrophobic skin adhesion promoters, and/or oil soluble actives are mixed in separate containers until homogeneous and heated to about 80 ℃. The oil soluble ingredients were added to the adjuvant ingredients and homogenized for 5 minutes until homogeneous and the resulting mixture was cooled to room temperature. During the cooling period, the remaining ingredients are blended into it.

The foundation composition of the present invention may then be formulated and packaged as an emulsion, or other acceptable carrier for foundation compositions. Tests conducted on the foundation composition provided in this example unexpectedly showed that the film-forming agent, emulsifier, and liquid oil work together to improve the synergistic effect of make-up retention and color retention of the foundation composition, and that the foundation composition has a non-greasy skin feel and appearance. The inventor also unexpectedly finds that the foundation composition has excellent makeup holding effect and excellent anti-darkness effect, and the inventor believes that the foundation composition has excellent anti-darkness effect due to the following reasons:

1. the coloring agent is compounded by triethoxycaprylylsilane and titanium dioxide, the triethoxycaprylylsilane can modify the titanium dioxide coating, and the coloring agent is dispersed in liquid oil compounded by cyclopentadimethylsiloxane and polydimethylsiloxane, so that the color does not change obviously when the coloring agent contacts air for a long time;

2. the film forming agent is trimethylsiloxy silicate, and the trimethylsiloxy silicate brings luster after forming a film through the synergistic effect of the film forming agent and the colorant, which is beneficial to the product to be lasting and not dull; the film-forming agent and the emulsifier have the synergistic effect to prevent the trimethylsiloxy silicate from forming a film which is too hard and brings a tight uncomfortable feeling, and the film-forming agent and the liquid oil have the synergistic effect to prevent the trimethylsiloxy silicate from forming a film which is too soft and can not fix the colorant on the face, so that the makeup and the card powder are easy to remove;

3. the emulsifier is PEG/PPG-18/18 polydimethylsiloxane, and the synergistic effect of the emulsifier and the colorant ensures that the appearance color of the foundation fluid composition is as close as possible to the painting color;

4. the thickening agent is disteardimonium hectorite, and the mass percentage range of the disteardimonium hectorite in the foundation fluid composition can be controlled to ensure that the colorant is dispersed in the foundation fluid composition more uniformly, thereby reducing the phenomenon of darkening and sinking caused by nonuniform dispersion of the colorant.

5. The liquid oil is compounded by cyclopentadecyldimethyl siloxane and polydimethylsiloxane, and the liquid oil has a high refraction value and can maintain the high refraction value for a long time, so that the liquid oil is beneficial to the foundation fluid composition to achieve the effect of resisting darkness.

The foundation composition may also contain any other additives commonly used in such compositions, including but not limited to dispersion promoters, oily gelling agents, humectants, softeners, UV-sunscreens, antioxidants, fragrances, defoamers, humectants, chelating agents, preservatives, cosmetic actives, water proofing agent additives, vitamins, vitamin derivatives, conditioning agents, botanical extracts, pharmaceutical actives, binders, essential fatty acids, sphingolipids, sunscreens, fat soluble polymers, polyacrylates, and silicone polymers compatible with fatty materials. One skilled in the art will be careful to select these other compounds and/or the amounts thereof which are useful so that the additives under consideration do not, or do not substantially, adversely affect the advantages of the compositions of the present invention. One skilled in the art can select these materials for use in order to prepare a composition having the desired characteristics, such as consistency or texture.

In addition, the foundation composition can be converted by changing the solvent to an oily gel, an oily liquid, an oil, a paste, a stick, or an aerosol form, or in the form of a carrier dispersion comprising an ionic or nonionic lipid. These pharmaceutical forms can be prepared according to the usual methods of the field under consideration. These topically applied compositions may be cosmetics for protecting, treating or caring for the face, neck, hands or body.
