Summer is coming, everyone likes to use sunscreen. What kind of sunscreen is safe and effective? Let's look at an experiment fromBASF scientistsfirst.BASF scientists have done an interesting experiment to study how sunscreen products produce free radicals after exposure to light. One group uses light-stable sunscreens, while the other group contains light-labile sunscreens BMDBM.As a result, it was found that formulascontaining light-labile sunscreenswould produce peroxidative free radicals

Agingis a natural phenomenon in the process of life. Although it is unstoppable, people can slow down the pace of aging through some means.Anti-aging cosmeticsare such a kind of cosmetics for the purpose of delayingskin aging. This kind of cosmetics can achieve the purpose of delaying skin aging through the following types of functional raw materials.1 Raw materials with functions of moisturizing and repairing skinSuch raw materials can keep the water content in the stratum corneum of the skin i

Melanin synthesisandmetabolismare closely related to melanocytes. Whitening skin care products generally inhibit melanin production and accelerate melanin metabolism through various links of melanocyte metabolism, so as to achieve the purpose of whitening.1. The common whitening ingredients areellagic acid(Pomegranate Peel Extract),palmitoylethanolamide(PEA, 98% up)and nonapeptide-1(99% up by HPLC), which affect the formation of melanocytes;2. Kojic acid, alpha arbutin,l-glutathione reduced(GSH,

In recent years, with the rapid development of thecosmetics industryand the widespread application ofgreen conceptsin various industries, anti-aging cosmetics have also put forward requirements for pure naturalness and non-toxic side effects. This is whynatural plant extractsare used inanti-aging cosmetics. The application has created a good foundation and premise. Adding natural plant extracts to cosmetics to realize the anti-aging function of cosmetics has become the development trend of the c

L-theanine（Theanine, CAS No.: 3081-61-6）isa unique amino acid of tea. It was first isolated from green tea in 1950. It is not only the characteristic amino acid of tea, but also one of the flavor substances of tea. It has a strong positive correlation with the quality of green tea, and the correlation coefficient is 0.787 ~ 0.876. There are more than 20 kinds of amino acids in tea, theanine accounts for about 50% ~ 60% of the total amino acids in tea; It is found that trace amounts have been d

Theanine(mainlyL-Theanine, CAS No.:3081-61-6), a health food that can not only hypnotize, but also relieve fatigue, reduce blood pressure and improve learning and memory ability, is rare and eye-catching. Therefore, theanine won the research department award at the international food raw materials conference held in Germany in 1998. Theanine is the most abundant amino acid in tea, accounting for more than 50% of the total free amino acids and 1% - 2% of the dry weight of tea. Theanine is a white

Scientists have discovered 9naturally occurringceramides(CAS No. 100403-19-8, also called Sphingolipid). In addition, there arephytoceramides,psuedoceramidesandsynthetic ceramides. Most ceramides in skin care products use synthetic raw materials, while ceramides in foods are mostly plant-derived, which is more natural and safer, but they are more expensive due to their lower content.1)Ceramide from riceThe content of ceramide in rice is about 3%, and the main component is glucosylceramide. Ceram
