From Licorice Source to Cosmetic Ingredient: What Traceability Adds to Glabridin Sourcing

A Glabridin sample can pass an initial evaluation without telling much about what will happen six months later.

The assay is acceptable. The appearance is within specification. The formulation trial works.

Then a new batch arrives.

If the material looks or behaves differently, the usual response is to check the finished ingredient first. Compare the COA. Repeat the analysis. Look at the approved sample.

With botanical ingredients, there is another place to look: upstream.

Glabridin starts with licorice, but the licorice used for extraction is itself part of the supply chain. Raw-material lots change. Agricultural sources can change. Harvesting, storage and processing all sit between the plant and the finished ingredient.

That history does not make the ingredient better by itself. It becomes useful when a batch needs to be understood.

From licorice to a defined ingredient

Glabridin is a characteristic flavonoid found in licorice, particularly Glycyrrhiza glabra. Its chemistry and biological properties have been extensively reviewed (Simmler et al., 2013).

For commercial use, however, “licorice-derived” is only the starting point.

Once the plant material enters production, extraction and purification determine the composition of the resulting active. The finished material is then supplied against a defined specification and analytical method.

This is one reason a glabridin supplier cannot be evaluated only by the botanical source or the first sample.

Two materials may both be described as Glabridin derived from licorice, yet differ in assay, physical form, manufacturing history and supporting documentation.

The first sample tells us whether the material can work. Long-term supply raises a different question: can the same defined material be maintained across subsequent batches?

When traceability becomes useful

Traceability does not need to be complicated to be useful.

At the practical level, the important links are between the raw material, production batch, analytical result and finished shipment.

Consider a simple situation. Two batches show different assay results.

The COA tells you what was measured in each batch. It does not necessarily tell you what changed before the material reached the laboratory.

If the finished batch can be linked to the incoming raw-material lot and production records, there is a basis for investigating the difference.

The same applies when an agricultural source changes.

A different source or raw-material lot is not automatically a quality problem. What matters is whether the change is documented and evaluated, and whether the resulting material continues to meet the agreed specification.

For botanical ingredients, this is a more practical approach to supply continuity than assuming the agricultural source will remain completely unchanged.

Purity still needs analytical context

The same thinking applies to Glabridin purity.

A specification of 98% or 99% is useful, but the number is only part of the information. The analytical method and the results from individual batches provide the context needed to interpret it.

HPLC and HPTLC methods have been reported for determining Glabridin in Glycyrrhiza glabra extracts (Viswanathan and Mukne, 2016).

An Intertek analysis of a Huatai Glabridin sample reported 99.3% Glabridin by HPLC, with a relative area of 99.71%.

That result belongs to the sample tested. It should not be treated as evidence that every future batch will produce exactly the same result.

For commercial supply, the more useful question is whether successive batches remain within the agreed specification. That is the practical side of glabridin purity. The percentage matters, but so does the ability to monitor it consistently over time.

The ingredient still has to work in the formulation

Traceability and analytical data do not remove the need to evaluate the actual commercial grade.

Glabridin can be supplied in different forms depending on the intended formulation. Huatai supplies 40%, 90%, 98% and 99% alcohol-soluble grades, a 10% water-soluble powder, a 1–5% water-soluble liquid and a 90% oil-soluble grade. The 10% water-soluble powder uses an HP-beta-CD inclusion complex.

The same active does not necessarily behave the same way in every formulation system.

A water-based formula and an oil-based formula may require different grades or different incorporation approaches. That makes glabridin solubility relevant during ingredient selection, not only after formulation problems appear.

Huatai has evaluated its 90% oil-soluble Glabridin in camellia oil. In a seven-day observation, the material remained uniformly dispersed, while the standard Glabridin used for comparison showed sedimentation.

The observation is specific to the tested material and system. It does not establish the same behavior in every cosmetic oil or finished formulation.

What the supplier needs to keep under control

Huatai sources licorice raw materials from cultivation areas in Kyrgyzstan and Uzbekistan and processes them at its production base in Yangling, China.

Knowing the source is useful. Being able to connect that source with the production batch, specification and analytical records is more useful.

This becomes increasingly important after the initial sample has been approved.

A botanical ingredient will move through different raw-material lots and production batches over its commercial life. The agricultural source may also change. The supplier’s role is not to prevent every change, but to keep those changes controlled enough that the material supplied to the customer remains defined and understandable.

For Glabridin, traceability is therefore not simply a way of documenting where the licorice came from. It is part of knowing what stands behind the batch that eventually reaches the formulation laboratory.
