How to remove the odor of collagen raw materials

Collagen will produce a unique odor during the production process, but it is not impossible to solve it. At present, there are two types of collagen on the market, one is dark in color and strong in smell, mainly produced by fresh animal skins: the other is color It is light and almost odorless, mainly prepared by hydrolysis of gelatin or using animal skins to undergo a long-term high-temperature and high-pressure process in the process (the gelatinization process in the gelatin market).

    Solution: First of all, it is the problem of the manufacturer. Even the fresh animal skin raw materials can solve the odor problem without the process of extracting the glue. Of course, this does not require the work of the majority of cosmetic formulators; when you encounter odorous collagen in the production of cosmetics It is possible to use cheaper cosmetic raw materials for compounding and use.It is not good to use fragrance alone, because too much fragrance will also cause skin irritation, and the volatilization of fragrance will also irritate the eyes.

    There is also a 0.1% addition amount, even if the odorous collagen has no effect in the final product. Or directly use light-colored collagen raw materials, but the effect of products using this type of collagen is average. I have used 1 Gelatin hydrolyzed collagen, 2 pig skin collagen (high temperature and high pressure hydrolysis), 3 pig skin collagen (low temperature enzymatic shearing technology), fish skin collagen (4 high temperature and high pressure hydrolysis, 5 low temperature enzymatic shearing) and 6 fish scale collagen Prepared into an essence lotion, the feedback information after the use investigation clearly shows the effect. (The two additions in the above various collagen essence lotions are the same) The results reported by users are 3>6>5>1,2 4 The collagen prepared from pig skin through low-temperature enzymatic shearing technology has the best wrinkle-removing and moisturizing effect, because it is known that pig skin is the closest to human skin and has the best affinity! Under the statement: This test is not fictitious. It is requested by the agent of our essence. Because the odor of pig skin collagen (low temperature enzymatic shearing technology) is very big, I hope to try to see if it can be used under the premise of ensuring the effect. Replace with other collagen with little peculiar smell or smell!

    After amino acid analysis of various collagens (raw materials and processes) (in the national designated analysis unit), it is found that their amino acid composition is basically the same, and the content of each component is also similar, but the difference in efficacy is there. There is no definite explanation as to why. The absence of bovine collagen in the above list is due to the source of raw materials: cowhide basically does not have most of the excess for leather making, and the leftover scraps are not suitable. The general bovine origin refers to the preparation of bovine bone gelatin, but the price is more than 1 times more expensive than pig skin
