Zn-Al LAYERED DOUBLE HYDROXIDE AS HOST MATERIAL FOR SUNSCREEN COMPOUND OF p-AMINOBENZOIC ACID
ABSTRACT: Zn-Al layered double
hydroxide can be used as host material for UV active compound p-aminobenzoic
acid (PABA), which is having capability to block UV light of sunlight. The
formation of Zn-Al-PABA was best developed in which the nucleation process was
done at room temperature and followed by hydrothermal treatment at 100oC. To make a better product, the molar ratio of
Zn to Al to PABA was adjusted to 3:1:1. From the elemental analysis and the
content of PABA, it was observed that the product has structural formula of
Zn0,745Al0.254(OH)1.650(PABA)0.349. 0.684H2O. The particle size of the powder
as estimated using SEM was in the range
100-200 nm. FTIR and XRD proved that the p-amino benzoate ion occupied the
interlayer space. This material is expected to have high sun protection factor
(SPF).
