UVプロテクション
ミネラルフィルター
Are we entering the age of mineral sunscreens? Nearly 16 percent of sunscreens launched in 2020 were mineral based, according to Mintel. Mineral sunscreen taps into formulas that include zinc oxide or titanium dioxide, as opposed to formulas with chemical ingredients, to reduce harmful ingredients, skin irritation and on a large scale, environmental impact.
Paired with dispersion, Sensient’s pure mineral filters create sun protection by absorbing and scattering UV energy. Natpure® Screen TWG, a dispersion of ultrafine titanium dioxide, is a convenient and effective solution for formulators seeking to enter the mineral sunscreen market. It gives greater control over sunscreen active ingredients and helps to ensure consistent UV protection.

The right viscosity is a sensory must for sunscreen. How do chemists maintain low viscosity for smooth application? By coating the pigment with what is called a surface treatment. Experts in surface treatment technology, Sensient has developed various surface treatments that:
- 分散性の向上
- より安定した、均質な、性能の高い処方
- 高顔料濃度での配合がしやすい
- より良い感性体験
- マッセでよりニクイ質感、肌への塗布も簡単
- より透明感のある肌へ
- 肌への白浮きを抑え、より自然な仕上がりに
- より優れたSPF保護性能
Technical properties:
- 高い疎水性
- 耐水性の向上
- 易分散性
- より良いSPF値
- 光触媒の安定性

Sensient has also developed expertise in pigment dispersions, which simplify formulation by eliminating the need for powders along with the equipment investments and labor requirements they bring. Simplicity aside, dispersions have many technical advantages, including higher transparency with no sedimentation, no re- agglomeration, and a two-year shelf life.

For both an SPF and sensory boost, beads deliver a combination of light reflection properties and sensorial impact. Sensibead® SI 175 and Covabead® Crystal are two popular bead solutions from Sensient that are globally compliant. Whether formulated with mineral or organic filters, these beads enhance SPF while achieving optimal water and oil absorption. Covabead® Crystal also adds blue light protection.

フィルムフォーマー
In addition of using surface treatments, water and shear resistance in sunscreen come from film formers. Sensient makes a wide range of transparent film formers, including natural film former like our Natpure® Film AP. Natpure® Film AP is a sugar-based film forming agent coated with acacia gum for extra flexibility and suppleness. Find out more here.
分散剤
A dispersant is a superior wetting agent: achieve high concentration of mineral filters with low viscosity increase which helps improve overall performance and aesthetics. Natpure® Feel-M Eco is an excellent natural emollient that acts as a non-volatile silicone replacement that nourishes the skin and offer low viscosity with any untreated and treated mineral filter.
