- Product Highlights
Our skin is an interface with the outside environment and, as such, is colonized by a diverse microbiota community. Certain bacterial species present in the axillary community have the capacity to transform non-odorous substances into volatile odorous substances by the action of enzymes. We can mention a very special involvement of Corynebacterium spp. and Staphylococcus spp.
The repeated use of deodorant to destroy the bacterial flora of the axillary microbiota does not appear to be the appropriate solution: bacterial abundance is decreased and led to the proliferation of inapropriate bacterial community when classical deodorant are stopped.
For this reason, GREENTECH designed a new active which limits proliferation of bad odors responsible bacteria without suppressing the other strains.- Action
- Reduces bacteria responsible for bad odors
- Maintains “good” bacteria
- Limits armpit bad odors
- Cosmetic Benefits
While preserving beneficial bacteria to respect microbiota balance, axillary bad odors disappear. LACTOPHYT® brings a sensation of comfort and freshness.

Technical Details & Test Data
- Scientific Mechanism
The objective is to limit the proliferation of species involved in the formation of malodour compounds.
Axillary microbiota Decrease of bacterial species responsible of bad odors
- Proven Efficacy
LACTOPHYT® limits growth of strains involved in the production of unpleasant odors, without disturbing “beneficial” bacteria competing with bacterial species generating bad odors.

- Clinical Study
COMPARISON WITH PLACEBO
Double blind test with 18 volunteers. One daily application on armpit during 3 days with
LACTOPHYT® 2% versus an active formula containing talc and a perfume (here named
placebo). Auto-evaluated sniff-test on a 0 to 6-scale from no odor to very strong odor
(disturbing others).DAY 1
ODOR INTENSITY
DAY 3
ODOR INTENSITY
* p<0.05 / vs placebo
LACTOPHYT® has a higher deodorant power than placebo.
COMPARISON WITH TRIETHYLCITRATE
Double blind test with 20 volunteers. One daily application on armpit during 3 days with
LACTOPHYT® 2% versus TRIETHYLCITRATE 1% (percentage usually used). Auto-evaluated sniff test on a 0 to 6-scale from no odor to very strong odor (disturbing others).DAY 1
ODOR INTENSITY
DAY 3
ODOR INTENSITY
* p<0.05 / vs Triethylcitrate
LACTOPHYT® has the same deodorant power as Triethylcitrate currently use on the market.
Lactophyt® has a high deodorant power based on its capacity to inhibit growth of bacteria involved in the production of unpleasant odors.
