Description
Technical Field
The invention relates to a hydrophobic oil-control powder with a soft-focus effect in amino acid treatment and a preparation method thereof, belonging to the technical field of cosmetics.
Background
The loose powder is one of face beautifying cosmetics, and is named as ' fixed make-up powder ', honey powder ' and ' loose white powder ' in the technical name. The loose powder is a powder product which does not contain oil and is prepared from powder raw materials. The powder is mainly used for coating after foundation emulsion or foundation cream is used, is mostly used for cosmetic after-decoration and make-up, adjusts skin tone, prevents greasy skin from being excessively smooth or sticky, shows dull but transparent skin color, reduces sweat and sebum, enhances the persistence of cosmetics, generates soft and fluffy skin feel, and has a certain sunscreen effect.
Soft focus originally means that a soft focus lens is used in photography or a soft focus filter is added in front of the lens, so that the photographed image achieves the fine and soft effect. "soft focus" in cosmetics is simply referred to as the haze of cosmetic particles, and the haze is the ratio of the scattered light flux to the transmitted light flux which are transmitted through a sample and deviate from the incident light direction, and the lower the light transmittance, the higher the haze, and the better the soft focus effect, and the soft light effect of cosmetics is generally measured by a haze meter.
The existing bulk powder base material mostly adopts spherical porous silica, the silica is oil control powder with soft-focus effect and high dispersion performance, the oil absorption of the silica is 180ml/100g, the silica is spherical powder, the touch is smooth, the silica is extremely easy to pave, pores can be effectively filled, fine line defects are covered, the surface of the silica is porous, the specific surface area is large, the silica can absorb grease, skin smoothness is maintained, and makeup and oil control are effectively maintained. However, the silica-based powder has the following disadvantages: on the one hand, silica becomes transparent after absorbing oil, which leads to oil-shine after a period of time, and the industry generally adopts silica with higher oil absorption to prolong the oil-control make-up effect. But the silica powder with larger oil absorption is more easily transparent after oil absorption, and the oil-light phenomenon is more obvious after saturation, so that the soft-focus effect of silica is lost; on the other hand, silica-based powders tend to be too powerful in absorbing oil and fat, and tend to cause dry skin; in addition, the porous silicon is easy to generate the phenomenon of powder flying due to light texture.

As shown in FIGS. 2-5, and in combination with the comparison of the properties of silica with calcium sodium aluminosilicate, it is seen that calcium sodium aluminosilicate has a more regular size combination than silica;
the aluminum calcium sodium silicate is a smooth solid sphere structure with a non-porous surface, and is different from a common porous silica surface in that a plurality of pores exist, so the aluminum calcium sodium silicate does not have the strong oil absorption and water absorption characteristics of porous silicon, and in addition, the solid structure of the aluminum calcium sodium silicate has larger specific gravity of the product, so the aluminum calcium sodium silicate is applied to a powder product and is not easy to fly.
