What is the chemical composition of the product (I am guessing it is not pre-used shampoo)?

Can you add water and dilute the remnant thereby creating more shower foam?

Dilution and mixing with new product may work to reduce your wastage, otherwise it looks like detergent will break down the solids.

As for disposal, well you will have to check the MSDS sheets and local regulations, but I am sure the (cosmetic) company you work for already has this sorted.

Tanks and handling systems for such product should have been fitted with internal scrapers/squeege to direct the material to the outlet point.

Seems like someone has taken on a new product line and found their first hurdle.

If you have just found this problem, then I can only guess there are others still to be discovered.

You (or someone else) may have been stirring the mix too extensive.I suppose the foam float on the product and the outlet of your tank is below?

1.You can make a new mix under the existing foam and consider it a process condition.

2.You can adapt the formula or the badge process to produce less foam.

3. Alcohol is considered a good foam dissolver and after the product is bottled or canned the foam comes back - I refer to a good bottle of beer. Prosit.

Is this why some shampoo products and/or shower foam products have SD alcohol in them?

I agree with other posters who mention that your method of agitation may be inappropriate or too vigorous. How about using a different stirrer design at a lower speed, and simply blending the batch for 10-15 minutes longer?

One possible other option is a cold blast to pop the bubbles. If that does not defoam the remnants, try a steam blast. One way or the other the bubbles will burst, and defoam.

I do not know what SD alcohol is. During our extensive coating processes when we produced conductive coating, we always had foam forming. A spray of alcohol takes care of that.

perhaps you need also to stop over agitation during product blending. Another idea would be to provide a dip tube (or other means) to introduce each product to the blend as a liquid with no entrained air bubbles, and introduce below the surface of other liquids, and not blend by rotation until all the materials are present in the specified amounts. Use only enough rotation speed and number of rotations to completely blend the ingredients (by tests) without introduction of entrained air.

This is a tried and true method for reducing large or small quantities of foam. Place a small amount of rug shampooer silicone defoamer into the mix as it is starting to foam. This works successfully every day for wives everywhere.

In the chemical industry we used it to get rid of large quantities of foam that would be generated in our waste water system. Foam was formed from cleaning reactors that contained natural oils with Sodium Hydroxide, water and heating the mix. The resultant material was similar to sodium stearate, the old soap that was made with lye and animal fats. It is similar to the old Ivory soap that made lots of bubbles. With a little experience we could knock down several hundred cubic ft of foam with an ounce or two of silicone defoamer (rug type purchased at the local hardware).

This is the same way that carpet cleaning machines prevent their vacuums from becoming clogged with foam. Next time you are in a hardware, or maybe a big grocery store, read the label on a bottle of carpet cleaner defoamer.

This method prevented potential embarrassment and possible fines when certain agencies were at the plant. We always kept a bottle handy in close proximity to the waste water plant is case it was needed.

Good Luck, Old Salt
