MoldGel Alginate SILFREE is considered the healthiest, safest and most environment friendly alginate formula in the market. It is silica free which makes it suitable for use on baby skin too.
Alginate is a simple dental impression material that lends itself well for making body molds. It is a natural material derived from seaweed and considered completely safe for the skin. The powder is mixed with water (in the defined proportions) and applied directly on the body to capture impressions for making life casts.

However, the alginate powder does contain some amount of crystalline silica which is considered a carcinogen. Even though the silica content is on the marginal side, EnvironMolds has developed a special silica free and dust free formula called MoldGel Alginate SILFREE.
This is made with food grade ingredients and is both environment and user friendly. To add to this, it is the only alginate that is fluoride free and lead free as well.
The powder mixes easily to give a smooth, creamy consistency which helps reduce mold voids due to air bubbles. It also yields greater coverage because of the mix ratio of 1 part powder to 7 parts water, (compared to 1:3 ratios for regular formulae). In fact, this has emerged as the highest yielding formula as it gives greatest value ounce-for-ounce.
Apart from the economical factor, the silica free Alginates provide excellent forensic detail down to the fingerprints. The delayed and gradual set time (4 to 5 minutes in MoldGel Alginate Silfree regular formula and 7 to 8 minutes in SloSet) allows a considerably longer window for working with the alginate mix. It further boasts of delayed shrinkage too and the casting time limit is extended up to 24 hours!
Finally, as MoldGel Alginate SILFREE is gentle on the skin and yields a softer set, it is ideal for casting hands and feet of babies and small children.
The formula is available in 1lb, 10lb, 20lb and 50lb packs on the EnvironMolds website, Artmolds.com. Other variants like Hollywood Impressions SILFREE and LifeMold Silica Free Alginate are also available.
