What are the special properties of boron nitride used in cosmetics

Boron nitride is a common multi-functional additive, mainly in the field of chemical applications, boron nitride has also been widely used in cosmetic formulations mainly because of its unique properties at the same time with a smooth texture, good adhesion, bright white gloss, Heat characteristics, and easy to cooperate with a number of advantages.

Now boron nitride is already a special material for cosmetic applications. Full use of the size of the differences in particle size, crystal size, and surface area and other physical properties to highlight the various needs on the formula. The classification of these specifications is the key to changing the characteristics of the formula.

The optical properties of boron nitride are substantially the same as those of the most commonly used cosmetic materials, with a slight increase in softness. In many powder materials, boron nitride is more prominent physical properties, boron nitride has a good dispersion effect of very low reflectivity, and shielding ability. In addition, boron nitride is also the single most effective ingredient in infrared sunscreen products.

To increase the direct transfer effect, the particle size or slip must be increased; to increase the dispersion effect of the powder particles must be relatively small, to reduce the reflection effect must also reduce the size of the particle.

Therefore, to highlight the soft-focus effect must choose the material that has a good transfer effect, a high degree of dispersion, and low reflectivity. However, all boron nitride specifications have the above basic demand characteristics. Choose to use boron nitride, the only can have these characteristics at the same time with high slip and high adhesion of good material.

Currently used in a variety of formulations, such as powder, foundation, eye shadow, lipstick, and rejuvenation formula. Thus, Boron Nitride does highlight the advantages of changing the visual effect in many formulations. At present, there are a number of different specifications for special requirements such as slippage, brightness, adhesion, and oil absorption coefficient.

The composition ratio of boron nitride in cosmetics
Lip and eye pencils 1-5%
Face and body powder 5-30%
Eye shadow/blushes 5-40%
Lipstick 2-5%
Concelaers/Foundations 3-7%
Skin care lotions 3-10%
Sunscreens 1-5%

Cosmetic grade boron nitride powder can be applied to foundation powder, powder, lipstick, talcum powder, eye shadow, blush, sun cream, and moisturizing skin care products.
