@ketchito thank for your information, but what i mentioned is floor cleaner formula, which has no LABSA, and use NaOH to adjust viscosity through increasing pH level, instead TEA. And when use pH to adjust viscosity in formula without NaCl, no matter which i use: TEA or NaOH, right?

[oldman20]

@ketchito i think it not make much different in formula i mentioned, cause NaOH ratio in that very small

[oldman20]

as the EO level increases water solubility and viscosity also increase, but salt-thickening and foam volume decrease. With increases in the alkyl chain length, salt-thickening and foam volume increase.

The difference of number of epoxyethane (EO) molecular in SLES lead to different function and application.

SLES (3EO) can create copious foam but a little more irritative, more suitable for producing dishwashing detergent.

SLES (2EO) has more delicate and fine foam, more suitable for producing shampoo and body wash products.

SLES (3EO) has better solubility, SLES (2EO) has better thickening performance.

but why use more than only preservative agent?

[oldman20]

i used LV at 2 Department of 2 Company long time without complain!

[oldman20]

Guar hydroxypropyltrimonium chloride is For low surfactant-based formulas, you mean that? Thank for information

[oldman20]

Thank your advice, i will try with phosphoric acid, but afaik it only help antirust metal? My main problem is that removing calcium deposits must be as strong as dissolving calcium deposits When dropping the solution onto the surface of stainless steel or porcelain

Should I maximize the ratio of Citric acid?

[oldman20]

what’s benefit when use TEA instead NaOH?

[oldman20]

please Citations, please. I need that information. Many thank!

[oldman20]

i agree too

[oldman20]

why pH 5 for disk washing formula? I think pH should around 8? for Fat hydrolysis?

[oldman20]

What’s about different between use NaCl vs MgSO4 as a thickener? i think only difference is cloudpoint

[oldman20]

what’s mean of sodium can interfere with the working of the carbomer? can u more clearly? i ussually use sodium hydroxide as thickener floor cleaner ( carbomer ez4) instead TEA

[oldman20]

hydroxypropyl guar is it formality of hydroxypropyl methylcellulose (hpmc)?

[oldman20]

yeah, i think this is correctly

[oldman20]

thank mate, i think reason is fragrance, like in that pdf mentioned. Have a good day to you

[oldman20]

The bottles made from HDPE, but problem occurs much more frequently with a particular product type than with the rest (they only differ in perfum)

[oldman20]

im too

[oldman20]

strange some info said SLES no sensitive in hard water, some said yes. But i think the answer is yes

[oldman20]

but you said it is “mistaken belief”?

[oldman20]

eutrophication of surface waters? what’s mean of it?
