The effect of simple syrup dilution in Berotec ® Syrup with other liquids was investigated with regard to changes in appearance and pH value. These changes were tested immediatly and 3 and 7 days after admixing at 30°C and 5°C. The decrease of redistribution occured in admixture with Pontal® Syrup and Asverin® Syrup. A cotton-like substance was observed in all cases of admixtures tested within 7 days at 30°C and identified by IR Spectrum UV Spectrum and high-performance liquid chromatography as Hydroxypropylmethylcellulose (HPMC) which was the additive in Berotec® Syrup.
