If i apply a moisturizer to skin after applying lactic acid exfoliant, doesn’t it increase the pH and reduce the effectiveness of of exfoliator?
-
Does it do it in
SecondsMinutesOr hours? -
@Perry thanks
-
I mean less than SLS liquid 28%.

If your emulsifier support it drop the pH to below 5. It will help your preservative a lot and is better for your skin too.
You don’t need pH above 6 for niacinamide. It works fine at pH 5 and below.
Why you want to move away from phenoxyethanol? It is one of the top preservatives in terms of effectiveness and mildness.

Perry said:The primary differences are these…1. Leave-in - Contains a high level of humectants, very low level (or none) quats. Lower level of most ingredients as you don’t need as much since it doesn’t get rinsed away.2. Rinse-off - Contains a high level of Quats. Not as much humectants since they aren’t really effective from a rinse off. Higher level of silicone also.Perry, 44
@pe@Perry how much humectant like glycerin would you recommend for leave in conditioner?
What is the benefit of humectants for hair?
-
@Padmavathi yes but then Paula’s choice has 4% leave on BHA. That makes me confused ????.
By the way, these are for skin. My question is are they safe for hair and scalp?
I had seen somewhere that salicylic acid makes the hair shaft weaker. But i cant find it now.

@Perry i thought this part mean coconut oil is a bit better than mineral oil.
Subjective grading of xerosis by the investigators and visual analogue scales used by the patients showed a general trend toward better (though not statistically evident) improvement with coconut oil than with mineral oil.

vitalys said:@Abdullah I assume 20% is too much for the moisturizing product. This high glycerin content will have opposite effect and the skin will become even drier.
@vitalys it also has petrolatum to prevent the evaporation. Why do you think the skin would become Dry?
In theory More glycerin will suck more water from lower to upper layer of skin and then petrolatum will prevent the evaporation of that water. So the upper layer of skin would be more moist. Also 20% glycerin function as skin protectant too.

@singhc10 how much citric acid do you think it has?
Aqua (Water), Hamamelis Virginiana Leaf Water, Cocamidopropyl Dimethylamine, Salicylic Acid, Dimethyl Isosorbide, Trisodium Ethylenediamine Disuccinate, Citric Acid, Polysorbate 20, Hydroxyethylcellulose, Ethoxydiglycol, Potassium Sorbate, Sodium Benzoate, 1,2-hexanediol, Caprylyl Glycol.

Results: Coconut oil and mineral oil have comparable effects. Both oils showed effectivity through significant improvement in skin hydration and increase in skin surface lipid levels. Safety was demonstrated through no significant difference in TEWL and skin pH. Subjective grading of xerosis by the investigators and visual analogue scales used by the patients showed a general trend toward better (though not statistically evident) improvement with coconut oil than with mineral oil. Safety for both was further demonstrated by negative patch-test results prior to the study and by the absence of adverse reactions during the study.
Conclusion: Coconut oil is as effective and safe as mineral oil when used as a moisturizer.
5% petrolatum and 20% glycerin?
Yes.
The purpose of this product is to provide maximum benefit as a moisturizer.
It is targeted to people with very dry skin. -
@Graillotion thanks a lot
-
@luiscuevasii thanks
my mixer is 2.2 kw. It sucks the shampoo very slowly when the viscosity has increased. It may not be able to suck SLES from pipe. That is what i think.Can you send the details of your double diaphagram!
Does it only need electricity to work or something else too. -
@Perry how do you compare mineral oil vs coconut oil when there already is 5% petrolatum in the formula?
This study shows coconut oil is a bit better than mineral oil for xerosis. -
Graillotion said:How about IPM then?
I just spent the last week trying to formulate it out of a formula…and the end result was…. I now have double the amount of IPM in the formula.
@g@Graillotion three ingredients that i thought you guys may recommend was isopropyl Myristate, isopropyl palmitate and coconut oil ????. There prices are also good.
what benefits did you like about isopropyl Myristate and how do you compare it to isopropyl palmitate and coconut oil?
-
@Graillotion the main criteria is it’s value for money and how much emollience and benefit it provide for skin.
Like Petrolatum and glycerin which are best in what they are supposed to do. not the skin feel. Although a drier skin feel is preferred.I already use 5% petrolatum and 20% glycerin in this product and am using dimethicone 5cst to adjust the skin feel. I have tested may moisturizers that have glycerin and petrolatum as first 2 ingredients after water and the skin feel is not very pleasant in ether of them so that is not a priority for me too.
what is good about macadamia nut oil? You have mentioned only label name.
What would you change for face hand and body product as emollient?Here only vegetable oils like sesame oil, mustard oil, flaxseed oil is available. I purchase everything from china and India so no problem in purchasing from these two countries.
-
@MattTheChemist the main focus is on how much emollience it provide and the value. In feelings the drier the better. Other things are not important.
-
@jamesmiju that could be the case. That is why it has red color so you know where you have applied and where not.
-
@MarkBroussard the question is why they say not to?
-
@Syl that is a good thing.
I love Amodimethicone. I haven’t noticed another benefit of it but i love touching my hair when it is dry after washing with a Shampoo with Amodimethicone ????????????. -
I see isopropyl palmitate in combination with glycerin and petrolatum a lot from big companies like Aveeno. What is your thoughts about this?
-
My hopper is like this
-
@Bill_Toge thanks. That looks like a good idea.
