@ngarayeva001 do you apply anything else on top of exfoliant?
-
@chemicalmatt thanks
So does it means if i apply a moisturizer instantly after lactic acid exfoliant it will reduce the effectiveness of exfoliant because it will increase the pH?
-
@singhc10 i thought Glucoside hydrolysis in pH below 5 but this product has pH 3-4. What am i messing?
-
@Perry what was the product, percentage of phenoxyethanol and percentage of people reacting?
And what alternative did you find for phenoxyethanol?
-
@Emotelle yes it was emulsion.
Why do i need to transfer EO from aluminum jar to glass bottle?
-
If you add 0.01% Cholecalciferol to an emulsion and apply 2g of that emulsion everyday and your skin absorbed 100% of vitamin D3 from it, you get 8000 IU vitamin D from that emulsion per day. ????
Now you calculate the rest of that.

@zetein why was it banned?
It is safe to be eaten then why it may not be safe to touch the skin? -
@vitalys thanks a lot
-
@PhilGeis thanks
-
@Perry Thanks.
Looks like AHA is doing it’s job immediately. -
@PhilGeis what is PPE?
-
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
