With the increasing popularity of color cosmetics products, the application of powder raw materials in cosmetics is becoming more and more widespread. Powders used in the cosmetic industry can be used to adjust the color tone of cosmetics and so on. PMSQ is an important raw material that is usually used in cosmetics. Why use Polymethylsilsesquioxane in cosmetics?
PMSQ powder has the effect of improving skin feel and is increasingly emphasized by beauty brands, covering skin care, color cosmetics, sunscreen, etc. PMSQ has a wide range of applications in cosmetics, such as color cosmetics, skin care creams, sunscreen sprays, etc. Its excellent thermal and thermal stability, as well as its ability to withstand the effects of heat and humidity, makes it a good product for the skin and the body. Its excellent thermal and chemical stability makes PMSQ an ideal cosmetic additive to improve the stability and extend the shelf life of cosmetics. In addition, PMSQ can also increase the smoothness and softness of cosmetics and improve their touch and texture.
There are four aspects of PMSQ in cosmetics:
- What powders can be used to improve cosmetics?
- What are the performances of PMSQ?
- What are the applications of PMSQ?
- How to improve PMSQ performance?
1. What powders can be used to improve cosmetics?
(1) Poly(methyl methacrylate) (PMMA)
PMMA has cross-linked and non-cross-linked two kinds, the hardness is lower than silica, which can regulate the fluidity of the product, and improve the molding of the product, there is no hiding power, smooth skin feel, the powder and powder has a lubricating effect, to improve their
In the powder and powder lubrication, improve the dispersion of pigments, to avoid the use of unevenness, in the skin surface to form a uniform film of smoothness, in the foundation and skin care products to provide a soft powder feel.
At present, the typical structure of commercially available PMMA is hemispherical, porous and non-porous, of which the average particle size of hemispherical PMMA is 9.0 μm, with high oil-absorbing value, the average particle size of porous PMMA is 8.0 μm, which can selectively absorb sebum and only absorb oil but not water, and the average particle size of non-porous PMMA is 7.0 μm, with low oil-absorbing value.
(2) Polymethylsilsesquioxane (PMSQ)
PMSQ is a spherical powder, particle size distribution is very uniform, and there are generally two microstructures, with a spike-like raised spherical PMSQ concealer effect than the spherical good, PMSQ particle size the smaller the more matte makeup, the larger the particle size of the more silky skin feel.
PMSQ has the stability of inorganic powder, and at the same time has excellent spreadability, smoothness, and mobility, and has good water resistance and a certain degree of oil-absorbing properties, by improving the light diffuse transmittance, changing the route of the light, bringing a soft-focus effect on the skin to help cover wrinkles and imperfections, to create a matte natural makeup, widely used in skin care, sunscreen and color cosmetics products.
XJY-801 Polymethylsilsesquioxane
It is a polymer formed from Methylsilsesquioxane, which is an insoluble, non-melting, three-functional component of dense cross-linked curing resin. Polymethylsilsesquioxane is a silicone round particles that can be used in many skincare and cosmetic applications because the backbone of all these silicone resins consists of repeating units of siloxanes, elemental silicones, and oxygen, which provide an excellent tactile sensation on the skin, the different grades of typical particle size can produce excellent performance benefits when incorporated into a variety of facial lotion and cosmetic formulations.
These benefits include reduced pigment aggregation in pressed powders and excellent spreadability in skin care and sunscreen products. Polymethylsilsesquioxanes have superior handling, which is primarily used to protect and condition the skin, reduce the appearance of fine lines and wrinkle masking effects through the use of foundations and decorative cosmetics, and may help to improve repair of the skin when it develops an aged appearance.
(3) Silicone elastomer powder
Silicone elastomer powder is generally vinyl polydimethylsiloxane or polymethylsiloxane silsesquioxane crosslinked polymers, the appearance of white spherical, with a raised surface, the average particle size of the powder is 12 μm. Such powders are obtained by using silicone resins cloaked with spherical silicone rubber particles, with a soft feel, a smooth feel, as well as excellent dispersion, but also to give the product an excellent soft light, soft focus effect to help conceal Wrinkles, pores, make-up more natural, suitable for use in formulations with oil control, soft focus effect.
(4) Nylon Powder
Nylon powder (Nylon), also known as polyamide powder, is a polyamide ester powder, that appearance of white microporous oval powder, particle size between 8.0 ~ 12.0 μm, and hardness is lower than PMMA, is soft, has good heat resistance, wear resistance, and self-lubricating, low coefficient of friction.
Personal care products are often used in nylon -6 and nylon -12 powder, the current surface treatment and modification of nylon is more widely used, the surface treatment of oleophilic increase, skin adhesion is good, spreading and tactile improvement is obvious.
2. What are the performance characteristics of PMSQ?
PMSQ is a silicone compound with a wide range of promising applications. Due to its unique silicone-oxygen bonding structure and regular molecular arrangement, PMSQ exhibits excellent thermal, chemical, and electrical insulation properties. In addition, the melting point of PMSQ is affected by the preparation method and conditions, while its molecular weight also has a significant effect on the melting point. With the increase in molecular weight, the melting point of PMSQ usually shows an increasing trend.
3. What are the applications of PMSQ?
Polymethylsilsesquioxane (PMSQ) is a silicone compound that is widely used in cosmetics and other personal care products. This compound has the following properties and effects:
(1) Touch and spreadability: Polymethylsilsesquioxane provides a soft touch and excellent flows freely, which can be used as a moisturizing agent, making it useful in a wide range of cosmetic applications, such as powder cakes, loose powders, foundations and powders, eye shadows, blushes, lipsticks, lip glosses, and sunscreen products.
(2) Skincare function: It has good skin care functions, including lubrication, anti-ultraviolet radiation effect, good breathability, slow release of flavors and fragrances, good surface slip and obvious dustproof function, and UV filters. This compound is non-toxic and non-irritating to the skin and mucous membranes, but irritating to the eyes, so it is considered safe.
(3) Enhancement of cosmetic effects: Polymethylsilsesquioxanes can enhance the spreadability and smoothness of cosmetic products, adding luster to them. In emulsified skin care formulations 4-10% is typically used to improve smooth skin feel, gloss, powdery, and softening effects, giving the formulation a delicate porcelain appearance. In make-up formulations, 2-5% is used to achieve anti-caking properties, smooth surfaces, and enhanced feel.
Polymethylsilsesquioxane (PMSQ) is a silicone compound with a wide range of application prospects, and its excellent performance characteristics have led to a wide range of applications in cosmetics, silicone powder, spherical silicone micro powder, and hair care, and other enhanced aesthetics fields. In the process of use, attention needs to be paid to its possible safety risks, and it is recommended that sufficient research and testing be carried out to ensure its safety.
4. How to improve the performance of PMSQ?
PMSQ can also be used as raw materials such as silicone powder and spherical silicone resin micropowder for the preparation of various cosmetic ingredients and personal care products. Silicone powder is a powder with excellent oil absorption and smoothness and can be used to prepare cosmetics such as foundations, loose powders, and eye shadows. Spherical silicone micro-powder is a microparticle with excellent moisture absorption and moisturizing properties, which can be used to prepare skin care products, shampoos, and other personal care products.
