Abstract: Matrix compositions comprising structurally diverse matrix particles (1) formed from at least five different types of primary particles distinguishable from one another due to different characteristics, shape characteristics, or both, (2) that constitute 15-50% of the matrix composition by weight, (3) that comprise or more types of particle agglomerates, (4) where at least 33% of the weight concentration of the matrix particle mixture being composed of UV-protectant metal oxide particles having a minimum particle size of over 100 nm, (5) where scanning electron microscope analysis of the composition fails to identify any significant number of discrete matrix particles of having a size of 100 nm or less, and (6) the composition exhibits one or more of sun protection factor (SPF) of at least 30, a critical wavelength of at least 370 nm, UVA/UVB ratio of at least 0.333, and a UVA1 to UV ratio of at least 0.7.
