Professional Chemist / FormulatorDecember 10, 2020 at 2:46 pm in reply to: Air freshener formulation@singhc10 thanks for the feedback, so adding alcohol can solve the problem but it increases the cost and even decrease the longevity of perfume for that I gone with no alcoholic product, for solubilizer peg 40 is not the best what I use I guess is better and there is no rule for solubilizer perfume Evry perfume has specific value, so for my solubilizer in some perfume just 1:1 ratio can lead to transperent product so the perfume is totally dissolved.

Professional Chemist / FormulatorDecember 9, 2020 at 10:28 am in reply to: lotion viscosity dropping@Shams may this information will help you, so lamesoft PO65 is mild tensio actif not as you said (superfatting agent), about your problem my suspect going to Sodium PCA because it is electrolyte an may it broke the viscosity made by ultrez so here is some idea I guess your product can be fine without the Sodium PCA unless you can change the ultrez by something not electrolyte sensitive as cellulose gum, xanthan gum…
Last thing the level of use of cetearyl alcohol seems high just decrease it I guess it will give better result. -

Professional Chemist / FormulatorDecember 9, 2020 at 10:06 am in reply to: Carbomer 940 compatibility with SLS in shampoo@Hamaadali008 you can use carbomer for that but it needs expertise because carbomer is very sensitive with electrolyte so you need to know the adequat amount for each ingredient to do the job, however SLS is ingredient easy to thick with other ingredients as slat.

Professional Chemist / FormulatorDecember 9, 2020 at 9:50 am in reply to: How do you work out the amount of emusifier?@Paprik Many things to tell you may help:
The cetyl Alcohol is fatty alcohol not emulsifier.
Soaping effect is normal effect of using emulsifiers so I think many things can help to reduce it depends on the best solution for you : you can reduce the amount of emulsifier, adding amount of Ethanol, using more low hlb emulsifier.
About ratio the best thing is making some sample even in low quantity to see the result because there is no best ratio for all systems as you already said. -

Professional Chemist / FormulatorNovember 27, 2020 at 9:02 am in reply to: Best Alcohol for perfume@Benz3ne I did not believe suppliers for cosmetic Ethanol because when I ask about the other ingredients they did not know exactly and about IPM and MPG by experience they did not have significant fixative effect.
@ketchito about IPA i’don’t think that toxicity because it is used with high level 75 % (v/v) as sanitizer. -

Professional Chemist / FormulatorNovember 25, 2020 at 2:38 pm in reply to: Best Alcohol for perfume@Pharma thanks for the answer about my definition of pharmaceutical Ethanol is Ethanol found in pharmacy and perfume’s Ethanol is Ethanol found in Cosmetics suppliers which is solding with very high cost,supposed contain fixative but actually I don’t really belive that.
And why many think that using isopropanol is bad idea to make perfume as I read? -

Professional Chemist / FormulatorNovember 12, 2020 at 8:50 pm in reply to: Sodium phytate %50 solution@Abdullah I guess that is bad idea for many reasons
1)powder form is more stable
2)Diluate it will almost need preservative
3) chelating agent in powder form is really easy to work with it so there is no convincing need according to me to Diluate it. -

@filiz for sure for Steareth-2 and Steareth-20 you need to go to hot process cause both are solid emulsifiers which need heating.

Professional Chemist / FormulatorNovember 10, 2020 at 6:04 am in reply to: My once clear serum spray is now cloudy@CarrieM actually as answer for your 3 questions according to me
1) there is always an order for better process or product for your case it is not really important
2) I guess that your product from lol supposed to be clear but if there is a suspect it will be about extract may the quality change from buying to other.
3) Your formulation have good ingredients really , just two things for verifying: is the viscosity good for serum then if your product is stable (preservation is it fine?)

Professional Chemist / FormulatorNovember 9, 2020 at 5:54 pm in reply to: Best ratio for SLES, c DEA, CAPB@Kunal adding salt is not mandatory, reduce viscosity can be done with deferent way I guess the best is making sample for low quantity as example take one kilogram make dilution with stiring then stop when you reach acceptable viscosity if your product is fine then no need to add correction else add some ingredients to improve It, repeat this process until you get what you want.
