Product Specification

What Is Horse Chestnut Extract Powder?

Horse Chestnut Extract Powder is a botanical extract from the seeds of Aesculus hippocastanum L., standardised mainly for its triterpenoid saponin content, Aescin (sometimes spelt Escin).

The main active ingredient is escin. It acts by strengthening capillary walls, lowering fluid leakage and normalising membrane permeability. These activities make it a highly studied substance for management of Chronic Venous Insufficiency (CVI), post-operative oedema and haemorrhoids.

Raw horse chestnut seeds contain a poisonous glucoside, Aesculin. Only well-processed and pure extracts are safe to use. During the extraction procedure, aesculin is removed by chromatographic purification and this is validated by each CoA with a particular HPLC limit test.

Third-Party Test Report

Each production batch is analysed in-house in HPLC, UV spectrophotometer and GC. Prior to export, samples are also sent to authorised third party labs such SGS and Eurofins for:

· Pesticide residue analysis

· Heavy metals analysis

• Microbiological analysis

· Optical rotation (specific)

· Nutrition labelling (if relevant)

Each order comes with a full test package. No surprises from Customs.

Horse Chestnut Extract Powder Advantages

Standardized Aescin at 20% HPLC — not UV

HPLC testing distinguishes unique Aescin isomers for an accurate estimate of the actual bioactive content. UV testing assesses total saponins and often overestimates potency. When you specify HPLC you are guarantyd a more dependable ingredient for consistent formulation performance.

Aesculin-Free Safety Profile

Raw horse chestnuts have a natural poison called aesculin. It is removed during extraction by our patented chromatographic purification process. The CoA always has a specified Aesculin limit test – this is non-negotiable for consumer safety compliance.

Plant-Based Venotonic, Clean Label

This extract provides a plant-based alternative to synthetic venotonics, facilitating clean-label positioning in dietary supplements and cosmeceuticals without compromise in demonstrable efficacy.

Certifications multiple for global market access

It is KOSHER, HALAL, BRC, ISO9001, ISO22000 and ORGANIC certified. This favours distribution into US, European and Asian markets with minimum regulatory friction.

Horse Chestnut Extract Powder Application

You’ll find this chemical in three different product categories:

1. Tablets Pharmaceuticals & Oral Supplements

It is the active ingredient in enteric coated pills and capsules used for the treatment of symptoms of CVI such as leg swelling, itching, varicose veins and venous fatigue. The powder is stable to tablet compression without degradation of the saponin structure.

2. Cosmeceuticals & Topicals Skincare

It is found in anti-aging creams, slimming gels, and anti-couperose serums. Aescin helps to maintain the structural integrity of the skin and to prevent capillary fragility by inhibiting hyaluronidase, the enzyme that breaks down hyaluronic acid. Water soluble grade clear aqueous serums are offered with extra filtration processing to prevent sedimentation.

3. Sports Nutrition & Recovery Formulations

It is added to post-workout formulas to help control oedema and promote fluid balance. The extract is chemically stable and does not react with other active substances when mixed with electrolytes and amino acids.

Production Process

Hongda uses a multi-step extraction procedure specially designed for saponin-class compounds:

1. Raw Material Selection Seeds obtained from reputable sources of Aesculus hippocastanum and confirmed for identity and purity on receipt

2. Solvent Extraction – Extraction under controlled temperature for maintaining the triterpenoid saponin structure

3. Chromatographic purification – selective elimination of Aesculin and other unwanted glycosides

4. Concentration & Spray Drying — Results in a homogenous, free-flowing dark yellow powder

5. Standardisation & QC Testing — HPLC determination of Aescin concentration, heavy metal, microbiological & pesticide testing

6. Packages - Double layer PE bags in fibre drums, 100,000 level purification workshop

The extract has a hygroscopic nature. Desiccants are used to seal drums and prevent caking during storage and shipping.

FAQ

Q1: What is the difference between UV and HPLC testing for this extract ?

A: UV measures total saponins, which tends to produce greater results, but less accuracy. HPLC will separate the different Aescin isomers, so that you can see the true bioactive content. Always specify HPLC when buying to make sure you do not have potency differences across providers.

Q2. How is Aesculin eliminated from the extract?

A: A patented chromatographic purification step in manufacturing removes Aesculin. Each CoA has an HPLC test for Aesculin with a specified limit. This is routine practice, not an option, to comply with consumer safety laws.

Q3: Can this extract be applied in clear aqueous cosmetic serums without precipitation?

A: There may be some sedimentation of standard grade in aquatic systems. For clear serums and gel cosmetics, request the water soluble grade, which is filtered and solubilized further to keep the finished product clear.

Q4: What is the correct way to store this ingredient?

A: Store in double-lined, firmly sealed polyethylene bags with desiccants. Store in a cool, dry place away from direct sunlight. The extract is hygroscopic and caking might occur when exposed to dampness. Re-milling generally restores flowability without degradation of Aescin content in case of caking.

Q5: Is it safe for formulators to include this extract to a supplement product with blood thinners?

Q: Does this drug, especially the high-dose formulations containing residual Aesculin, interact with anticoagulants? Extracts free of Aesculin show unusual important interaction. As a common compliance precaution, formulators should put drug-interaction warnings on labels.

Q6: What documentation are accessible for regulatory filing?

A: Hongda offers complete CoA, MSDS, specification sheet, third party test reports (SGS/Eurofins), and certification copies (KOSHER, HALAL, BRC, ISO9001, ISO22000, ORGANIC). Additional documentation, such as nutrition labels, natural origin reports, or precise optical rotation data, are available upon request.
