China Powder Network News At present, powder raw materials are more and more widely used in cosmetics, such as pigment powder, white powder, body powder and pearl powder, etc., and their applications in skin care, color makeup, oral care and other fields have been very mature.
Among them, pigment powder is used to adjust the color tone of cosmetics; white powder has the functions of covering, whitening, and blocking ultraviolet rays; there are many kinds of body powder, and the main function is to adjust product spreadability, adsorption, skin-adherence, texture, and lighten vision. Focus and load active ingredients, etc.; pearlescent powder can improve product gloss and texture.

1 Physical powder - common inorganic powder
Because physique powder can effectively improve the skin feel of cosmetics, more and more beauty brands pay attention to it, and it is widely used, covering skin care, color makeup, oral care, sunscreen and other fields. Body powders include inorganic powders, organic powders and natural powders. The most commonly used inorganic powders are talc, mica, silicon dioxide, calcium carbonate, and perlite.
2 3 major applications of inorganic powder in cosmetics
2.1 Skin care - scrub, soap, shower gel, talcum powder
Mica powder
Mica powder is a general term for a group of complex hydrated aluminum silicate salts, which are light gray scaly crystalline powders. Mica powder has strong adhesion and moderate gloss and softness. After special processing, it can be made into synthetic mica, which can improve the whiteness, brightness and durability of color cosmetics products. , liquid foundation, etc.
perlite
Perlite minerals provide gentle physical exfoliation in scrubs, soaps and body washes while promoting lather formation and are an ideal natural alternative to oil-based beads and pumice stones.
calcium carbonate
Natural calcium carbonate can be incorporated into various skin care product lotions and anhydrous formulations. They provide a smooth and comfortable skin feel, reduce stickiness and speed up drying. In addition, calcium carbonate is also widely used in soaps, in addition to reducing costs as a filler, calcium carbonate can also enhance skin care and the amount and speed of foam generation, while enhancing the brightening effect of soaps.
Kaolin
Kaolin clay is ideal for improving sebum absorption, provides a soft touch to body powders, has excellent skin adhesion, and increases matting potential in powders. In addition, the kaolin and diatomaceous earth ranges impart excellent fine exfoliation, barrier formation and sebum absorption properties in moisturisers, day creams, BB creams, CC creams, anti-acne creams and creams for oily skin, as well as improve the rheology of the product control.
talcum powder
Talc is a white fine crystalline powder with a layered structure, with good lubricating feeling, soft texture, moderate adhesion, high whiteness and certain covering power. Talc has good lubricity, soft texture, moderate adhesion, high whiteness, and certain covering power. It is the most commonly used filler in powder products, mainly used in the manufacture of fragrant powder, powder cake, talcum powder, etc.
2.2 Makeup - lipstick, foundation, blush
calcium carbonate
The brightness and opacity of high-purity calcium carbonate make it suitable for use in decorative cosmetics such as lipsticks, foundations, blushes and eyeshadows. They adjust the coverage of the product and provide a matte finish through sebum absorption. For example, calcium carbonate is used in lipsticks to enhance coverage and color intensity. When used in powder cakes, the compressibility, moderate hardness, excellent whiteness, and diverse powder morphology of calcium carbonate powder make it an ideal choice for pressing powders.
Kaolin
A naturally white kaolin solution that imparts an instant, natural matte finish to pressed powders when used in pressed powders, improves pressed powder durability, uniformity and adhesion, and reduces titanium dioxide usage. In addition, in lipstick products, kaolin can enhance the product's adhesion and oily retention. Kaolin is also an ideal filler in products such as mascara and nail polish.
silica
Spherical silica, ultra-fine silica, porous silica, various products, widely used in various cosmetics, very rich functional properties. In lipsticks, it can increase viscosity, improve overall stability, uniform pigment distribution, improve temperature resistance, and prevent discoloration; in makeup and eye care (including compact powder, foundation, rouge, eye shadow, eyebrow liner and eyeliner) etc.), silica is an efficient anti-caking agent and free-flowing agent, can improve storage stability and powder product dispersion.
2.3 Oral Care - Teeth Cleaning, Teeth Whitening
calcium carbonate
High-end calcium powder for oral care, with calcium carbonate core and hydroxyapatite shell, widely used in toothpaste. Hydroxyapatite is the main component of enamel and dentin in teeth, and calcium carbonate ensures effective remineralization of enamel by repairing microscopic defects, resulting in a smoother, whiter tooth surface.
Kaolin
Kaolin is added to toothpaste to achieve the best balance between cleaning performance and abrasiveness, toothpaste with kaolin is about half as abrasive compared to toothpaste with hydrous silica, helping to keep teeth healthy while still Shows excellent cleaning performance.
perlite
Particle size engineered perlite is a milder polish used in toothpaste.
Epilogue
Inorganic powder is used in cosmetics, and its naturalness, mineral quality, chemical inertness, good skin tolerance and price are several important characteristics. At present, the powder processing technology and modification technology are gradually mature, and the application of functional mineral powder in the cosmetics industry is also a very promising development direction.
