Protection contre les UV
Filtres à minéraux
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.
Traitements de surface
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:
- Améliore la dispersibilité
- Formule plus stable, plus homogène et plus performante
- Plus facile à incorporer dans une formule à forte charge pigmentaire.
- Une meilleure expérience sensorielle
- Texture plus agréable dans la masse, application facile sur la peau
- Plus de transparence sur la peau
- Moins de blanchiment sur la peau pour un aspect plus naturel
- Meilleure protection SPF
Technical properties:
- Haute hydrophobie
- Meilleure résistance à l'eau
- Dispersion facile
- Meilleure valeur SPF
- Stabilité photocatalytique
- Données in vivo disponibles
Cosmetic benefits:
- SPF amélioré
- Étalement plus important
- Moins de blanchiment
Dispersions
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.
Perles
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.

- Sensation de poudre sur la peau
Covabead® Crystal
Technical properties:
- Faible absorption d'eau et d'huile
- Propriétés de réflexion de la lumière
- SPF Boosting avec filtre minéral et organique
Cosmetic benefits:

Formateurs de films
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.
Dispersant
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.
