About Technology

>The Ordinary Salicylic Acid 2% Anhydrous Solution is a water-free product formulated to exfoliate the skin and help decongest pores. Direct acids, specifically alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs), are renowned for their ability to support the natural shedding of dead skin. While AHAs aim to promote superficial exfoliation, Salicylic Acid (SA), a lipophilic BHA, is particularly effective at targeting oil within the pores that can lead to congestion. The Ordinary Salicylic Acid 2% Anhydrous Solution offers salicylic acid in a squalane base formulated with the intent of reducing concerns of skin irritation that can be associated with the use of SA.

Ingredients >Squalane, Caprylic/Capric Triglyceride, Pentylene Glycol, Salicylic Acid, Oleic/Linoleic/Linolenic Polyglycerides, 4-t-Butylcyclohexanol, Hydroxymethoxyphenyl Decanone, Phenoxyethanol, Chlorphenesin.

Instructions >Apply in the morning and evening. Apply a small dot to the target area or apply a small amount over the face for general use. Do not use on sensitive, peeling or compromised skin. Avoid the eye contour and contact with eyes. Patch testing prior to use is advised: Apply the product as directed to a small area once a day for three days to test if you are sensitive to this product. If you develop irritation, hives, swelling of eyes and mouth, blistering, or difficulty breathing, rinse off, cease use, and consult a physician right away. Keep out of reach of children.

>Sunburn Alert: This product contains a beta hydroxy acid (BHA) that may increase your skin's sensitivity to the sun and particularly the possibility of sunburn. Use a sunscreen, wear protective clothing, and limit sun exposure while using this product and for a week afterwards.

In search of a safer NPS for the final isolation in the citric acid isomerisation I'm wondering about drying the soup once the bicarb has been added and then using ethanol/acetone to extract the thc.

My chemistry knowledge is limited to high school theory, so patience and feedback (especially safety related) greatly appreciated!

Citric acid + bicarb produce Monosodium Citrate if I'm not mistaken, which is insoluable in ethanol. Citric acid is soluable, but bicarb isn't, so

1. to confirm, is it monosodium citrate that is produced?

2. would adding excess bicarb be permissible to ensure the citric acid is fully reacted?

3. is the following overall process mostly sound?

4. dH2O + citric acid + cbd, heat at 120C in reflux for desired time

5. add bicarb to neutralise, produces Monosodium citrate

6. dry the soup (on hot plate, or in drying chamber)

7. add ethanol

8. filter off citrate/bicarb

9. evap ethanol, left with isolated cannabinoids

Hello,

On many sites featuring food and drinks bad for HIT/MCAS I have seen tea and coffee as drinks that are blocking DAO. Is it just because of the caffeine content or is it about other methylxanthines besides the caffeine itself and other stuff in it? Is anhydrous caffeine better for someone with a low DAO (I had test for it myself) than those aforementioned caffeinated drinks? Personally I had the worst mood drinking pu-erh tea.

Hi guys, for the life of me I can’t figure out if I can mix my water based geek and gorgeous ascorbic acid vitamin c serum with the ordinary resveratrol & ferulic acid serum which is an anhydrous while carrying on with the rest of my routine with water based serums as I’ve always been told that anhydrous serums should be last but I wanted to mix both serums to boost efficiency and create a powerful antioxidant mix

How do I do this step? :)

Hello, I've been experimenting with supplements, lifestyle, and diet changes in order to deal with my homozygous MTHFR c677t gene mutation. This brought me to experiment with TMG however, I'm struggling to find reliable information on timing (empty stomach, before or after meal?) and dosage. Any help will be appreciated!

I remember I bought 250g off of amazon around 7 years ago, and now I've run out. But, I can't seem to find it on amazon, or on any of the usual nootropic websites, even. Is selling pure caffeine banned now, or something?

**Edit: Guarana seems to be my best option? Anyone have experience with that?

**Edit2: Does anyone know if "meets FG specifications, FEMA 2224" means what I think it means, that it's "food grade" and same to consume? I'm referring to this.

We currently process a RTD electrolyte beverage that has anhydrous dextrose. Adding the anhydrous dextrose is the most troubling ingredient, when we add the ingredient to the powder mixer we have, we have many issues with the ingredient creating big rock-like chunks and blocking the cone of the mixer, so the ingredient has to be added very slowly and this obviously impacts production efficiency a lot. Just adding 200 pounds of the ingredient takes over an hour.

Using dextrose monohydrate will help us dissolve the ingredient faster?? Please correct me if I am wrong but I am thinking since it already has some water in it, it should be a little less hygroscopic and allow us to add the ingredient faster without creating big clumps. Any one has some experience working with these ingredients?

Hi guys, I wanted to ask you about the temperature and pressure at which anhydrous ammonia is stored as a liquid, as I can't find it online. I also wanted to ask you that in case ammonia is to be turned into liquid, what unit operation would be used? vaporizer or evaporator?

If I pass a current through anhydrous acid, what would end up getting reduced? Hydrogen or phosphorus? Can this method be used to remove water from H3PO4 to form P2O5?

Because I wanna make you wet and then we can react

For quite a while I've used rosehip oil instead of moisturiser (I know facial oils are not the same as moisturisers, but this works for me and I'm not looking to change it). I hate the feeling of facial oil sitting on top of my skin, but when I apply a few drops to damp skin straight out of the shower/after warm wash cloth and rub it in, it sinks in nicely and doesn't feel heavy.

I've started to use a Vitamin C serum, so it is just serum, oil, and sometimes SPF in my routine. The one I have is a slightly thicker, anhydrous serum (this one from FaceTheory). It feels a touch heavy too, but again when applied to a damp face it sinks in and feels better.

The problem is, by the time the serum absorbs properly, my skin if course is no longer damp and warm, so now the rosehip oil isn't absorbing as well (or feels on my face like it isn't absorbing as well) compared with when I used oil alone as the first/only step.

I suppose I could mist my face before applying the oil, but I'd assume that might lift off some of the serum, plus it's still not quite the same as my skin has cooled down by that stage.

Since the serum is anhydrous, I wondered if I could mix it in with the oil without it losing its efficacy, as without containing water I would think that it would blend completely with the oil and therefore be absorbed as part of the same 'step', rather than the oil getting in the way of serum absorption like it would if you applied oil before serum. Buuut maybe this isn't how it works. Can anyone shed some light on this? And/or provide any hot tips for getting the oil to feel like it's absorbed better? It's such a sensory thing for me, I really hate the feeling of it sitting on my skin, but I love rosehip for my combination skin and don't want to switch to something lighter like a squalane.

Not a chem student just a tourist. So I’m used to seeing acids used in solutions of various concentrations and I know citric acid is crystalline (if that’s the right term) when pure but do all acids do this? Can you have 100% pure Fluoroantimonic acid for instance, and would it be crystalline?

I'd like to perform a simple caffeine extraction, I have all the glassware required to do everything up o the recrystallization as it requires a vacuum filtration apparatus, which i do not currently have the funds for. Would gravity filtration work? I assume it would take much much longer to perform, but a buchner funnel, filter flask and bucnher filter paper, just arent something i can afford at the moment as i am a student so i'm running on an extremely tight budget.

According to the manufacturer, MG Chemicals, their Isopropyl Alcohol has less than 0.001 g/100 mL non-volatile residues.

Yet, after the solvent dries, I see it leaving many streaks on glass surfaces and clear plastic surfaces.

Is there something wrong with my batch of Isopropyl Alcohol?

So, regular caffeine has absolutely no effect on me whatsoever for some reason. Never has. Tolerance isn't the issue either. So I'm looking at caffeine anhydrous and wondering, if regular caffeine does nothing for me, that probably won't either, right? Or - and I hope this is true - am I wrong?

I would love to hear opinions on how you all would proceed given these materials.

Ideally I would like to make full use of the mag stirrers for the pulls, as of right now I'm only using them to facilitate the addition of NaOH and so I don't have to stir my chocolate milk.

Does anyone know when Ulta will carry the new salicylic acid from The Ordinary in stores?
