Products Description
Esculin hydrate 98% is also known as sapogenin. Its core raw material is the dried bark of the bitter nut juniper tree (Qin Pi). It is a highly active flavonoid monomer component extracted from Qin Pi. The dried Qin Pi is purified through various modern processes such as cleaning, low-temperature alcohol extraction, multi-layer chromatography purification, membrane separation for impurity removal, and other techniques. These processes maximize the retention of the original molecular structure and activity of esculin, effectively removing excess impurities and eliminating solvent residues. The stability is high. The finished aescin powder is a uniform and fine white crystalline powder. The powder has a dry and loose texture without lumps. It has almost no odor and only an extremely faint natural plant herbal aroma. The Esculin hydrate98% powder has good water solubility and can quickly dissolve in warm water or hot water. After dissolution, the solution is clear and transparent, without turbidity, no precipitation, and no suspended impurities. It can also be compatible with organic solvents such as ethanol, and is suitable for various formulation systems such as water-based and alcohol-soluble ones. The pH tolerance range of esculin is wide. It is stable in weak acid, neutral conventional formulation systems, and is not prone to oxidation, color change, or deactivation and deterioration. The formula tolerance rate is extremely high.

Function
Esculin hydrate 98% has excellent free radical scavenging ability, with stable and mild antioxidant performance. It can effectively resist oxidative damage caused by the external environment, improve skin dullness and roughness, and delay the aging process of the skin. It can also delay the oxidation and deterioration of food raw materials, lock in the effective activity of the product, and assist in extending the stable period of the final product. Compared with ordinary antioxidant raw materials, it has a long-lasting activity and is not easily affected by slight fluctuations in the environment, resulting in a more long-lasting effect.
Esculin has its own gentle soothing and repairing properties. It can effectively alleviate redness, dryness, sensitivity and discomfort of the skin, repair the damaged skin condition, and enhance the skin's own tolerance. Long-term use can stabilize the skin condition and make the skin texture more delicate and stable.
Esculin contains natural antibacterial and anti-inflammatory properties, and has a good inhibitory effect on various common harmful microorganisms. In the formula, it can assist in antibacterial and preservative functions, reducing the addition of chemical preservatives.
Application
The beauty industry is the most important application field of Esculin. It is often added to categories such as essence water, repair essence, lotion, cream, mask, and cleansing products.
In the field of food and health supplements, Esculin is commonly used in various types of dietary supplements such as tablets, capsules and powders. The raw material is naturally safe, has no side effects and no residues, and is suitable for the research and development needs of health and wellness products.
In the field of pharmaceutical intermediates, the high-purity 98% grade Esculin is an important raw material for pharmaceutical fine intermediates. It can be used in the research and production of related drugs.
In the field of personal care products, it can also be used in functional personal care and oral care products.
