矿物防晒成分
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.

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.

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.

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.
