Study on improving menthol adsorption performance of silica particles by olege
[Objective]To improve the menthol adsorption properties of silica.[Methods]Fragrance-absorbing particles were prepared using silica adsorption-melted menthol oleogel.The impact of palm oil addition ratio on the oleogel hardness,oil binding capacity,and thermodynamic properties was investigated.Comparative particles microstructure,flow properties,and the loaded menthol encapsulation efficiency,storage stabilityand release characteristics to assess the enhancement of silica particle adsorption properties by the oleogel.[Results]When palm oil addition ratio were 50%and 80%,the oil binding capacity of oleogels were over 90%,and the hardness and peak melting temperature of the gels increased with the palm oil ratio.Microscopic observations revealed the adsorption of oleogels on the surface of silica particles.Encapsulation efficiency of menthol increased from 73.43%to 82.05%and 91.19%,while storage endpoint encapsulation efficiency rose from 30.77%to 69.83%and 80.28%.Concurrently,menthol sustained-release properties were enhanced.[Conclusion]Oleogel effectively improves the adsorption properties of silica particles for menthol.
