Aspartame
Aspartame is a low-calorie artificial sweetener approximately 200 times sweeter than sucrose (table sugar). It is a methyl ester of the dipeptide composed of aspartic acid and phenylalanine. Due to its intense sweetness and low-calorie nature, aspartame is widely used as a sugar substitute in various food and beverage products. It is popular among consumers seeking to reduce caloric intake, especially diabetics and those on weight management programs. Aspartame breaks down at high temperatures, limiting its use in certain cooking or baking applications. It is approved by numerous global food safety authorities, including the FDA and EFSA.
Carbocisteine AJI 92
Carbocisteine AJI 92 is a high-purity pharmaceutical-grade amino acid derivative, chemically known as S-carboxymethyl-L-cysteine. It is a white to off-white crystalline powder with a slightly sulfurous odor and is freely soluble in water. Carbocisteine functions primarily as a mucolytic agent—reducing the viscosity of mucus and promoting expectoration in respiratory tract infections. The "AJI 92" specification refers to its compliance with the purity standards established by Ajinomoto's amino acid quality benchmarks, ensuring it meets stringent pharmaceutical-grade quality control for active pharmaceutical ingredients (APIs). It is widely used in oral syrups, tablets, and granules in both human and veterinary medicine.
Carbomer
Carbomer is a high molecular weight, crosslinked polyacrylic acid polymer used primarily as a rheology modifier, thickening agent, and suspension stabilizer.
