The invention relates to the cosmetic field and particularly relates to a cosmetic composition containing a whitening compound. The cosmetic composition contains the following components in percentageby weight: 1%-3% of nicotinamide, 1%-4% of the whitening compound, 0.5%-1.5% of a citrus peel extract, 0.1%-0.5% of arbutin, 0.1%-5% of an artemisia umbelliformis extract and the like, wherein the whitening compound contains water, butanediol, arbutin, citric acid, sodium sulfite, acetyl tyrosine, a saxifraga sarmentosa extract, a peony root extract, aminopropanol ascorbyl phosphate, a scutellaria root extract, glutathione and hydrolyzed mirabalan. The cosmetic composition has the characteristics that by finely selecting the raw materials with a synergistic effect at each whitening node, thecomposition has a synergistic whitening effect; the composition is capable of inhibiting the activity of tyrosinase and the transfer of melanin and brightening the skin color, has a common synergisticeffect at each node in a whitening process, and finally, the safe, effective and stable whitening effect is achieved.

The invention belongs to the technical field of cell culture, and particularly relates to a knockout serum replacement for cell culture and a preparation method thereof, a knockout serum replacement composition for cell culture and a cell culture medium. The knockout serum replacement for cell culture comprises, by weight, water, 18.5-67 parts of amino acid, 200-815 parts of protein, 62.5-252 parts of inorganic salt, 1.0-3.8 parts of ethanol amine, 50-200.0 parts of sodium pyruvate, 1.25-5.0 parts of ascorbyl phosphate, 0.5-2.0 parts of glutathione and 5.0-20 parts of insulin. The knockout serum replacement for cell culture can be added into any one cell culture medium, the adding amount of serum is reduced, and therefore, the cost is saved. The knockout serum replacement for cell cultureis suitable for protein recombination, vaccine production and other kinds of cell culture, and high in universality.
