| Объект | Подробнее |
| Химическое название | Гидроксипропилтриметиламмонийхлорид гиалуроновая кислота |
| Номер по CAS | The CAS number may vary depending on the specific preparation and is not as commonly publicized as some more well – known compounds. It might require specific research in chemical databases for an exact number. |
| Молекулярная формула | Hyaluronic acid is a polysaccharide composed of repeating disaccharide units of D – glucuronic acid and N – acetyl – D – glucosamine. When modified with hydroxypropyltrimethylammonium chloride, the exact formula becomes more complex. The quaternary ammonium group from hydroxypropyltrimethylammonium chloride is likely to be attached to the hyaluronic acid backbone, perhaps through an ether or ester linkage. The overall formula would incorporate the elements from hyaluronic acid (C, H, O, N) along with those from the modifying group (C, H, N, Cl). However, without detailed structural analysis, a precise formula cannot be given. |
| Молекулярная масса | The molecular weight of hyaluronic acid can range from thousands to millions of daltons depending on its degree of polymerization. The addition of hydroxypropyltrimethylammonium chloride groups will increase this weight. The exact increase depends on the number of modifying groups attached and their molecular weights. So, the molecular weight of hydroxypropyltrimethylammonium chloride hyaluronic acid can be a wide range, potentially from a few thousand to much higher values. |
| Молекулярная структура | The hyaluronic acid backbone has a linear structure with alternating sugar units. The hydroxypropyltrimethylammonium chloride groups are attached to the hydroxyl groups on the sugar units of hyaluronic acid. The positively charged quaternary ammonium group ( – N(CH₃)₃⁺) imparts cationic properties to the molecule. This modification can change the overall charge distribution and the way the molecule interacts with other substances. |
| Внешний вид | It usually appears as a white to off – white powder or a viscous gel – like substance, similar to native hyaluronic acid but with potentially different physical properties due to the modification. The powder form may be more common for solid – state formulations, while the gel form can be used in topical applications. |
| Растворимость | Native hyaluronic acid is highly soluble in water. The addition of hydroxypropyltrimethylammonium chloride groups can further enhance its solubility in water due to the hydrophilic nature of the quaternary ammonium group. It may also show solubility in some polar organic solvents, depending on the degree of modification and the nature of the solvent. In general, it has good solubility in aqueous – based solutions, which is beneficial for its use in various products. |
| Функция в промышленности | Косметика: It is widely used in skincare products. The cationic nature of the modified hyaluronic acid allows it to interact strongly with the negatively charged surfaces of the skin. This leads to better skin adhesion, enhanced moisturization, and improved skin feel. It can help in reducing the appearance of fine lines and wrinkles by retaining moisture in the skin. Уход за волосами: In hair care products, it acts as a conditioning agent. It can coat the hair shaft, reducing static, improving combability, and providing a smooth and shiny appearance. The positive charge of the quaternary ammonium group can attract to the negatively charged hair surface, providing long – lasting conditioning effects. Биомедицинские приложения: It may be used in some biomedical applications, such as in drug delivery systems. The modified hyaluronic acid can be used to encapsulate drugs and target them to specific tissues or cells. Its biocompatibility and ability to interact with biological surfaces make it a promising candidate for such applications. |
| Стабильность | It is generally stable under normal storage conditions, typically at room temperature in a dry place. However, like hyaluronic acid, it may be sensitive to extreme pH values, high temperatures, and the presence of certain enzymes. The quaternary ammonium group may also be subject to chemical reactions under specific conditions, such as reaction with strong oxidizing or reducing agents. In formulations, appropriate stabilizers may be added to maintain its stability over time. |
| Вопросы безопасности | Hydroxypropyltrimethylammonium chloride hyaluronic acid is generally considered safe for use in the concentrations typically used in consumer products. In cosmetics, it has a good safety profile and is well – tolerated by most skin types. However, as with any chemical, some individuals may be sensitive or allergic to it. In industrial applications, proper handling procedures should be followed to avoid contact with eyes and skin, and adequate ventilation should be ensured during use. |
