Ensuring Accurate Formulation of Liquinox Detergent

Q. I am a validation manager and we use Liquinox in multiple pieces of equipment across our manufacturing site. While witnessing our cleaning, I noticed the dilution instructions are not being followed. Instead, operators are adding some squirts/pumps/pours from the bottle into a bucket with purified water. Does Liquinox have a range of effective concentration?  Do you have auto-mix ideas or other dosing solutions for customers facing this issue of accurate formulation?

Ideal pH Range for Ultrasonic Cleaning with Liquinox

Q. What is the acceptable pH range of Liquinox for effective cleaning in an ultrasonic bath? Our solution hovers around 7 and I am concerned that’s not effective. Also, does the temperature of the ultrasonic cleaning solution affect the detergent pH?

A. A typical reading for Liquinox® Critical Cleaning Liquid Detergent at usage dilution is ~pH 8.5. A pH 7 reading on Liquinox detergent would indicate that a notable amount of fouling has occurred from use.

Minimum Detergent Concentration?

My question is related to a minimum detergent concentration.  We manually wash labware of all sizes in 0.3% Liquinox solution. We also pre-wash or pre-rinse the labware and control our parts load.  We rarely have failures. We want to change our protocol to extend the wash water use for one day instead of based on a numerical parts load.  Do you think a 0.3% Liquinox concentration is sufficient detergent capacity to go an entire day?

Maximum Liquinox Percentage

Q: We are having a difficult time cleaning our parts in an ultrasonic tank. What is the maximum percentage that you can have of Liquinox detergent? What hazards are there?

A: The concentration percentage of Liquinox™ Critical Cleaning Liquid Detergent can go up to a 100% in theory. There is no hazard, per say, however, the rinsing can become more difficult as you increase the concentration.
