The poor dispersion of mineral sun filters is a major constraint encountered during the formulation of sun care products. This is because the Sun Protection Factor (SPF) is directly linked to the proper distribution of filters and screens on the skin. Some ingredients have proved to be highly effective in improving the SPF of a formula without increasing the percentage of filters. Thus, LaraCare® A200 and Olivem® 1000 Crystal Skin™, ECOCERT active substances extracted from North American Larch and Tuscany Olive Oil respectively, have demonstrated their efficacy as SPF boosters. 
Both act by homogenising the distribution of (organic and mineral) filters on the skin.

Whilst stabilising the emulsion by reducing the size of particles in the dispersed phase, LaraCare® A200 (INCI: Galactoarabinan) acts by steric bulk, which limits the forces of attraction between the filters. Aggregate formation is reduced and decreases the percentage of filters for equivalent efficacy.

Olivem® 1000 Crystal Skin™ (INCI: Cetearyl Olivate; Sorbitan Olivate), is capable of generating liquid crystals that are biocompatible with the lipid layer of the stratum corneum. The latter act as filter transporters, distributing them uniformly on the surface of the skin “by merging” with the hydrolipid film.
