A composition comprising a physical sunscreen, one or more adjuvants, and a carrier oil is provided. The composition also includes at least one of a compound having multiple phenyl groups, a film former or dispersant, and a silicone surfactant. The composition may also include an organic sunscreen. The combination of these ingredients exhibits an unexpected synergistic effect, in that the photoactive properties of the composition (e.g., SPF, UV absorption) are significantly higher than would be predicted based on the values for each of the components individually.

Enhanced photoactivity of semiconductors and/or sunscreens

A novel three-component synergistic preservative system has zinc oxide, a phenoxyethanol component, and caprylyl glycol. The preservative system provides sufficient preservative activity without the use of other preservatives such as parabens. It provides broad spectrum activity against yeast and molds, and remains effective long term.

Synergistic preservative system

A method of analyzing metal oxides. In this method, metal oxide is provided, heated with microwaves, and a conductivity parameter of the metal oxide is determined. From the conductivity parameter, a determination is made regarding a pyroelectric effect of the metal oxide.
