Seedlac vs Shellac Flakes vs Dewaxed Shellac: Which Should You Buy?

One resin, three stages of refinement

All three products are the same natural resin — lac, secreted by the Kerria lacca insect on host trees — at different points in the refining chain. Seedlac is the washed, sieved raw material; the wash water from sticklac also yields lac dye. Shellac flakes are seedlac melted, filtered and stretched into thin sheets; shellac is also the raw material for aleuritic acid. Dewaxed shellac goes one step further, removing the natural wax by solvent processing. Each step adds purity, consistency — and cost. The buying question is never "which is best" but which refinement level your process actually needs.

The comparison at a glance

Seedlac — the base grade. Reddish-brown granules, roughly 3–5% natural wax, small residual impurities by nature. It is the cheapest per kilo and the right buy for anyone who does their own processing: shellac manufacturers, large coating houses with dissolving and filtering capability, and traditional industries. If you have filtration in-house, buying seedlac and refining yourself is the most economical route.

Shellac flakes — the workhorse. Filtered and consistent, still carrying the natural 3–5% wax, supplied in colour grades from deep orange through blonde to garnet. Right for wood finishes, polishes, general industrial coatings, inks and adhesives — anywhere a slight natural haze from wax is acceptable or even desirable (French polishers often prefer waxy grades for workability). Mid-priced, dissolves readily in alcohol, no further processing needed.

Dewaxed shellac — the precision grade. Wax below 0.2%, giving crystal-clear solutions and glossy, haze-free films. This is the specification for pharmaceutical tablet coating, E904 food glazing, clear wood lacquers on pale timbers, and cosmetics. Highest cost per kilo of the three — but if your application demands clarity or food/pharma compliance, there is no substitute, and buying a cheaper grade simply moves the cost into rejected batches.

Comparison table

Form	Seedlac: washed granules · Flakes: thin sheets · Dewaxed: thin pale sheets or powder
Wax	Seedlac: about 3–5% · Flakes: about 3–5% · Dewaxed: 0.2% or less
Colour	Seedlac: by crop (Kusmi paler, Baisakhi darker) · Flakes: lemon, orange, blonde, garnet · Dewaxed: Platina to Garnet
Solution in alcohol	Seedlac: needs filtering · Flakes: slightly hazy · Dewaxed: clear
Price level	Seedlac: lowest · Flakes: middle · Dewaxed: highest
Typical use	Seedlac: further refining, varnish, adhesives · Flakes: French polish, sealers, inks · Dewaxed: clear finishes, tablet coating, cosmetics
HS code	All three: 1301 90 99 in India, HS 1301.90 internationally

Four questions that decide it

• Do you process in-house? Yes → seedlac saves real money. No → flakes or dewaxed.
• Does the end product touch food or pharma? Yes → dewaxed, with E904-compliant documentation. This is non-negotiable for EU markets.
• Does film clarity matter? Clear finishes on light surfaces → dewaxed (or dewaxed bleached for near-white). Warm traditional finishes → standard flakes, where the wax adds character.
• What colour does the formulation need? Flakes come in orange, blonde and garnet; deeper colours cost less and suit dark woods and inks, paler grades suit light applications.

The mistakes we see buyers make

Two errors account for most wasted shipments. First, buying flakes for a food application to save cost — the wax haze and missing compliance documents surface at the customer's QC, not yours. Second, buying dewaxed for rustic wood finishing — paying a premium to remove wax the craftsman would have valued. Matching grade to use, not price to budget, is what keeps landed cost low.

The fastest way to be sure: send us your application (or your current supplier's COA) with your enquiry — we will confirm or challenge the grade before quoting. It costs nothing and has saved more than one buyer a container of the wrong material.

The short version

Process it yourself → seedlac. General coatings and traditional finishes → shellac flakes in the right colour grade. Food, pharma, or clarity-critical → dewaxed, documented. Same tree, same insect — the difference is purely how much refinement you pay for, and the right answer is written in your application, not the price list.

Quick answers

What is the difference between seedlac and shellac? Seedlac is washed, sieved lac granules, the raw material. Shellac is seedlac that has been melted and filtered into flakes or button lac, which makes it cleaner and more consistent.

Which is better for wood finishing, shellac flakes or dewaxed shellac? Waxed flakes suit traditional French polish used on its own. Dewaxed shellac is better when another finish goes on top, or when you need a clear film on pale wood.

Is dewaxed shellac food grade? Dewaxed shellac is the starting point for food grades, but in the EU only wax-free bleached shellac meets the E904 specification. Ask for E904 food-grade shellac with a batch COA.
