Problems solved by technology

However, silica-based powders have the following disadvantages: On the one hand, silica will become transparent after oil absorption, causing makeup to become oily after a period of time. The industry usually uses silica with higher oil absorption in order to prolong oil control and makeup. Effect
However, silica powder with greater oil absorption will become more transparent after oil absorption, and the glossy phenomenon will become more obvious after saturation, thus losing the soft focus effect of silica itself; on the other hand, the ability of silica powder to absorb oil is too high. Powerful, it is easy to cause dry skin; in addition, porous silicon is prone to flying powder due to its light texture

Embodiment 1

[0054] Such as figure 1As shown, Example 1 of the present invention provides a hydrophobic and oil-controlling powder with amino acid treatment and a soft-focus effect. The powder includes the following components in parts by weight:

[0055] Component 1: 63 parts of silica;

[0056] Component 2: 27 parts of calcium sodium aluminum silicate;

[0057] Component 3: 3 parts of lauroyl lysine;

[0058] Component 4: 2 parts of polydimethylsiloxane.

[0059] A method for preparing powder in above-mentioned embodiment 1, it may further comprise the steps:

[0060] Step 1: Put 60-80°C deionized water 40-50 times the weight of component 1 into the stainless steel bucket, set the speed of the electric mixer at 300-500rpm, and stir the deionized water to form a vortex;

[0061] Step 2: Add 1 / 10-1 / 5 sodium hydroxide by weight of component 3 to the deionized water in step 1 and wait for it to be fully dissolved, then drop component 3 into the stirred solution, and continuously disperse...

Embodiment 2

[0069] Embodiment 2 provides a kind of hydrophobic oil control powder with soft focus effect treated with amino acid, the powder includes the following components in parts by weight:

[0070] Component 1: 50 parts of silica;

[0071] Component 2: 20 parts of calcium sodium aluminum silicate;

[0072] Component 3: 1 part of lauroyl lysine, 1 part of lauroyl sarcosine;

[0073] Component 4: 1 part of triethoxyoctylsilane, 1 part of polydimethylsiloxane.

[0074] The method for preparing the powder in the above-mentioned Example 2 is consistent with that of Example 1.

Abstract

The invention discloses hydrophobic oil-control powder treated by amino acid and having a soft coke effect and a preparation method of the hydrophobic oil-control powder, and belongs to the technical field of cosmetics. The powder comprises the following raw materials in parts by weight: a component 1: 50-70 parts of silica; a component 2: 20-40 parts of sodium calcium aluminum silicate; a component 3: 1-5 parts of one or two of lauroyl lysine and lauroyl sarcosine; and a component 4: 1 to 4 parts of one or two of triethoxyoctyl silane and polydimethylsiloxane. According to the invention, the silicon powder and the sodium aluminum calcium silicate are scientifically combined and proportioned, and after composite treatment, the light and smooth skin feeling and oil absorption and control effects of the silicon powder are retained, and meanwhile, the long-acting soft coke effect of the sodium aluminum calcium silicate is also played, the oil gloss is inhibited, and the long-acting soft coke effect is achieved; the surface of the powder is treated by amino acid, and flaky amino acid components are introduced, so that the skin-friendly property of the powder is improved while the moisture is preserved, and the dry feeling of the silicon powder after oil absorption is reduced.

Description

technical field [0001] The invention relates to a hydrophobic and oil-controlling powder with a soft-focus effect after amino acid treatment and a preparation method thereof, belonging to the technical field of cosmetics. Background technique [0002] Loose powder is a kind of facial beauty cosmetics. The professional name is "fixing powder", also known as "honey powder" and "loose white powder". Loose powder is a powder product that does not contain oil and is all made of powder raw materials. It is mainly used after foundation lotion or foundation cream, most of which are used for post-beauty touch-ups and make-up, to adjust skin tone, prevent oily skin from being too smooth or sticky, show dull but transparent skin color, reduce sweat and sebum, Enhance the durability of cosmetics, produce a soft, fluffy skin feel, and some loose powders also have a certain sunscreen effect. [0003] Soft focus originally refers to using a soft focus lens or adding a soft focus filter i...
