What Does 20 PPM Mean in Colloidal Silver? A Simple Buyer’s Guide

If you have ever compared bottles of colloidal silver, you have probably seen PPM written on the label. You may see 10 PPM, 20 PPM, 40 PPM or other concentrations — but what does that number actually mean?

This guide explains PPM in plain English, what it tells you about a colloidal product, what it does not tell you, and the other details worth checking before you buy.

What does PPM mean?

PPM stands for parts per million. It is a way of describing concentration. In a water-based colloidal mineral, the PPM figure tells you approximately how much of the mineral is present relative to the liquid.

For example, a product labelled 20 PPM colloidal silver contains approximately 20 parts of silver for every one million parts of solution.

That makes PPM useful when comparing one bottle with another — but concentration is only one part of the picture.

Is a higher PPM always better?

No. A higher number simply means a higher concentration. It does not automatically mean a better-made product.

When comparing colloidal minerals, it is more useful to look at several things together:

• the stated PPM concentration;
• the purity of the source metal;
• the type and purity of the water;
• whether salts, proteins, preservatives or stabilisers have been added;
• the production method;
• the bottle size and price per 100ml;
• and whether the manufacturer clearly explains what is actually in the bottle.

A straightforward formulation with clearly stated ingredients is often much easier to compare than a product making dramatic claims without explaining its composition.

Why Crystal uses 20 PPM for its core colloidal range

Our main colloidal silver, copper, zinc and magnesium liquids are produced as clearly labelled mineral-and-water formulations. The core range is built around a concentration that is easy for customers to understand and compare across products.

You can see the full range in our colloidal products collection.

20 PPM vs 40 PPM: what is the difference?

The difference is concentration. A 40 PPM liquid contains roughly twice the concentration of the named mineral compared with a 20 PPM liquid, assuming both measurements have been produced and stated accurately.

That is why our Colloidal Gold is labelled differently from products such as Colloidal Silver, Colloidal Copper, Colloidal Zinc and Colloidal Magnesium.

The PPM figure is therefore useful for understanding concentration, but it should not be treated as a universal measure of quality.

What else should you look for on a colloidal silver label?

A useful label should make the product easy to understand. Look for the mineral name, concentration, bottle size, ingredients and any relevant directions or cautions.

Our standard colloidal silver formulation is deliberately simple: high-purity silver and steam-distilled water. We do not need a long ingredient list to describe what is in the bottle.

Does bottle size change the PPM?

No. PPM describes concentration, not total bottle volume.

A 500ml bottle of 20 PPM colloidal silver and a 1 litre bottle of 20 PPM colloidal silver have the same stated concentration. The larger bottle simply contains more liquid.

This is an important distinction when comparing value. Two products can have the same PPM but very different bottle sizes and prices.

Why water quality matters

Water makes up almost the entire volume of a simple colloidal mineral product, so it is worth knowing what type of water is used. Crystal Health & Beauty uses steam-distilled water in its core colloidal range.

Distillation removes dissolved minerals and many impurities before the water is used in production. This provides a clean, consistent base for making the colloidal liquid.

What about particle size and ionic content?

PPM alone does not tell you the size of particles in a colloid or the proportion that may be present in ionic form. Those are separate characteristics.

This is one reason why comparing products only by asking “which one has the highest PPM?” can be misleading. Concentration is useful information, but it is not a complete technical description of the liquid.

Colloidal silver compared with other colloidal minerals

The same basic concentration principle applies across the wider colloidal range. The mineral changes, and the product specification may change, but PPM still describes concentration.

• Colloidal Silver — 20 PPM core silver liquid.
• Colloidal Copper — available in 500ml and 1 litre sizes.
• Colloidal Zinc — a simple zinc and steam-distilled water formulation.
• Colloidal Magnesium — part of the core mineral range.
• Colloidal Gold — sold at a different stated concentration, so check the individual listing.

What does 20 PPM colloidal silver mean?

It means the product has a stated silver concentration of approximately 20 parts per million.

Is 20 PPM stronger than 10 PPM?

Yes in terms of concentration: 20 PPM is twice the stated concentration of 10 PPM. That does not automatically make it a better product.

Is 40 PPM twice as concentrated as 20 PPM?

Yes, based purely on the stated concentration.

Does a bigger bottle have a higher PPM?

No. Bottle volume and concentration are separate measurements.

What should I compare besides PPM?

Check ingredients, metal purity, water quality, production information, bottle size and price alongside the stated concentration.

The simple takeaway

PPM is best thought of as a concentration number. It helps you compare how much of a mineral is present in a liquid, but it does not by itself tell you everything about quality, purity or production.

When choosing between colloidal products, look at the whole specification rather than chasing the biggest number.
