Professional Chemist / FormulatorOctober 29, 2024 at 9:53 am in reply to: Free Aluminum cream deoi saw such description that says use TEC at ph <5 , however i find other paper that says the ph of TEC is between 6 and 8 … actually i got effective deo using TEC and zinc oxide may the deodorant activity is from only Zinc oxide .
About the activity of TEC i guess may by application underarm the ph changes and TEC will be actif?

Professional Chemist / FormulatorOctober 28, 2024 at 9:09 am in reply to: Viscosity problem in emulsionAs always , awsome comment from expert @ketchito. Thanks a lot for sharing your interesting knowledege , my big guess was about cooling ratio (because it is the most important difference between labo and production scale) . about ratio (turbine diamater /reactor diamater) laboratory > ratio (turbine diamater /reactor diamater) production

Professional Chemist / FormulatorOctober 28, 2024 at 8:23 am in reply to: Viscosity problem in emulsionActually it is not really problem because we got nice texture (better texture then laboratary sample) and viscosity is acceptable just i want to understand the phenomen . About the speed of turbine i guess it is not the reason because we turn off it at high temperature where the viscosity reached the maximum of viscosity so the decreasing of viscosity is in function with temperature decreasing only in that case .
just we took two samples from production one without turn on turbine after 50 °C and one with then there is not really important difference between them.

Professional Chemist / FormulatorOctober 25, 2024 at 6:22 pm in reply to: Why ppg 15 stearyl ether?Actually almost you said true about it is lighweight, emollient and solvent however i Never read That There is an evidence between Lightweight oil and anti irritation effect ، also all function said can be done by other ingredient sush as c12-15 alkylbenzoate.So my problem is wich thing has ppg 15 that others hasn’t May as you said something related of aliminum chlorohydrate.

Professional Chemist / FormulatorOctober 24, 2024 at 7:30 am in reply to: Viscosity problem in emulsionTwo productions for shared formulation , but the curve is repeated for others creams always in evry production ( at T=50 °C the viscosity drop dramatically where there is no add to any ingredient preservative , parfum..) .
And there is only production and laboratory scale .

Professional Chemist / FormulatorOctober 2, 2024 at 9:52 am in reply to: What makes emulsion loose viscosity?Thanks a lot for your comment, I wrote full lol but when cream loose viscosity I didn’t add preservative and perfume, about stirring it needs high speed stirring to get good viscosity 600 rpm is low.

Professional Chemist / FormulatorSeptember 23, 2024 at 8:16 am in reply to: What is the best actif or combination for whitening cream?I already make a lot of researchment about vitamin c and (Mpg, glycerin) will be choice.
Now the problematic is it will be better to use maximum of solvents enhancers for a synergy or it will be better to use the best (one or two) enhancer(s) alone.

When adding dimethicone 350 to cream the viscosity decrease more. Can you guess why?
