Test Request 17-01777
LONG-TERM TESTING Cosmetics Laboratory needed for testing of multiple skin care projects in development. Quotes are needed on the following analytical services on finished released and excipient testing:
Release testing of Pramoxine Hydrochloride
Release testing of Hydrocortisone
Release testing of Zinc Oxide
Release testing of Titanium Dioxide
Release testing of Aluminum Sesquichlorohydrate
Finished good testing in a lotion and a spray
Finished good testing of in an ointment
Finished good testing of Zinc Oxide (17.0%) in a lotion
Finished good testing of Titanium Dioxide (2.3%) in a lotion
Finished good testing in a cream
Aside from release testing for the APIs listed above, do you routinely do release testing for cosmetic excipients, such as peptides, vitamins, humectants, etc...? I ask this question, because until we have a QC lab up and running, we will need to partner with outside labs to complete this testing. Would there be any savings if we were to submit multiple samples at once?

LONG-TERM TESTING Analytical Chemistry Laboratory needed for accelerated aging study with testing monthly for a year.
Tests needed (per sample, per testing interval):
1. pH by electrode (single replicate)
2. Total active chlorine by electrode (duplicate)
3. Chloride ion by ion chromatography (duplicate)
Accelerated aging for two solutions: Unbufferrd HOCl solution, approx. 500 ppm and
#2. Buffered HOCl solution, approx. 500 ppm
50-60oC, dark (no pressure specified)
Once every 4 weeks for 1 year on a schedule I establish and send to you (based on when my client sends the samples)
My client will send 1 L of each solution, divided up into two 500 mL amber bottles (exact sizes still not provided). Both should be stored in the aging chambers, but only one should be sampled when performing tests (the other is back-up).
You will send the data to me and address questions/issues to me, but my client will be responsible for payment. IMPORTANT NOTE: Please send detailed quote with response.
Test Request 17-01623
Large chemical company needed analytical chemistry laboratory for identification of sulfur species in liquid samples. Analysis of our sample by XRF shows the presence of sulfur but our GC instruments don't detect any sulfur. We use a GC equipped with a PFPD and a non-polar capillary column. We have also used a GC with FPD and non-polar capillary column. We suspect the sulfur that is present is non-detectable by GC (or at least not by our system).
