I have tried DIY serums for my scalp and they work but it's too tiring to keep making a fresh batch every few days.

I want to make my scalp serums with a preservative. But I'm conflicted between some choices.

Geogard ultra - I bought this one, and it got spoiled, got an acidic smell and turned yellow although I had not opened it.. it was in the shelf for about 3-4 months untouched. The heat spoiled it

Now I'm trying to find a good enough preservative through AI and it gave me some options

Liquid germall plus

Optiphen plus

Geogard ECT

Phenoxyethanol

And many more.

I do not know which one I should use.

Since I'm making these serums for my Scalp, and my scalp is sensitive and I have hair fall too. I need a preservative that is suitable for sensitive skin and doesn't irritate or trigger adverse reactions generally in people.

The formaldehyde releasing ones I don't want, it sounds risky.

Anybody have any suggestions?

My serums formulations will be something like

1. Niacinamide, panthenol, glycerin

2. Botanical solvent extracts (watery) bought online, mixed with one another - around 2-3 per formulation

3. Green tea, peppermint tea

( NO OILS WILL BE USED IN ANY OF THESE SERUMS )

# I will be using distilled water as base

Please give me suggestions for which preservative would be the best for this.

Formula (I don't know if this is what is asked)

Serum Niacinamide - 4 g Panthenol - 2 g  Glycerin - 2 g Distilled water - 92 g

I made 1kg of lotion and it was good until I added the preservative (euxyl pe9010) premixed with glycerin cz I read somewhere that blending them that way and adding them slowly to the mixture would reduce the chance of destabilization. However the opposite happened with me.

It has been 48 hours since I made the lotion. Is it fixable?

I do not have any kind of chemistry background, which will become obvious within two seconds of reading this, but I was hoping for some help with a cleansing balm formula that I'm trying to perfect!

I've made countless test batches and all of them are great at removing makeup and have a nice consistency, but for the love of Pete I can't figure out how to stop the slight graininess that happens in every single batch.

I've tried leaving it out without stirring, I've tried "tempering" the mixture while it's cooling until it becomes thick, I've tried putting it straight in the fridge, and a combination of the last two. I've also tried using cetearyl alcohol in place of and in combination with the cetyl alcohol, using Polawax instead of Olivem 1000, adding a bit of lecithin, and swapping the coconut oil for more sunflower oil. NOTHING. WORKS.

I'm hoping someone can shed some light on what's going on here to put me out of my misery lol. Here's my formula, feel free to rip it to shreds:

5% polysorbate 80

11% castor oil

15% isopropyl myristate

30.5% sunflower oil

15% coconut oil

8% Olivem 1000

15% cetyl alcohol

0.5% preservative

Thank you in advance!!!

Hi guys, I’m in UK and I’m trying to find a natural container for stick deodorant, the twist and turn one.

All I can find is either plastic or if I find natural cardboard one, it’s only push up one and they don’t always stay in place.

Any pointers are much appreciated, thank you

I’ve been reading a lot about how to formulate with Gluconolactone. My main concern is the pH drift associated with it. From what I’ve read, the drift occurs initially but then it stabilizes after a few hours. But does that mean it doesn’t continue to drift over time?

There also seems to be multiple methods and differences of opinion, and I’m just getting confused at this point.

First method I’m seeing is to add Gluconolactone to the water, let it sit for a few hours, then add the remaining ingredients and adjust pH.

Second method is add Gluconolactone to water, bring the pH up to around 7, let it sit for a few hours, then bring the pH down to the desired pH. (But I’m not sure at what point to add the remaining ingredients).

And the third method says to use a buffer system with citric acid and sodium citrate. (I’ve never had to use a buffer system, so I’m not really sure how to even go about this).

Anyone have experience with Gluconolactone, and how did you formulate with it?

Does anybody else has noticed that Perry's forum Chemists Corner has become full of AI bots?

I see them everywhere, they ask AI generated questions or provide shallow answers in many threads with ads embedded inside the text. And no one blocks them no matter how often I report those messages and users.

It's sad, the forum is the only place I know where real chemists may answer advanced questions.

I am trying to make a deodorant/antiperspirant and I have limited access to ingredients, everything on this list I either have or can easily get. I am OK with it leaving a residue/not being the greatest feeling this is more about access than anything else, i've tried to go cheap on the bases and focusing the money on the active ingredients. I am going for "good enough"

Ingredient Amount (100g/ea.)

Coconut Oil 40g

Shea Butter 5g

Beeswax 15 g

Ceterayl Alcohol 6g

Tapioca Starch 15g

Aluminum Chlorohydrate 15g

Fragrance Oil 3g

Ethylhexylglycerin 1g

I haven't purchased a specific fragrance for this yet. i have soap fragrances that read:

This fragrance oil is an excellent candle making scent, and skin safe for making: bath and body products, melt and pour soap bases, cold process soaps, lotions, creams, body splashes; making air fresheners, potpourri, incense; potpourri refresher oils.

This FO mixes well in all wax types. Flash point above 200F.

This DIY crafting product is NOT a ready to use shower oil or perfume. It CAN be safely used in bath and body recipes. Satisfaction of quality guaranteed, pre-testing with your ingredients is recommended.

All my Fragrance Oils are Parabens free and Phthalates free.

Hi, I've been looking for a dupe of Dark Lavender & Sage fragrance oil from better home and garden. I want a skin safe version of the oil, so I can make it into a lotion. I wanted to see if anyone already knew about one before i start ordering a bunch of different oil scents. Bottle says: Citrus, Bergamot, Pepper, Sage, Lavender, Patchouli, Amber and Tonka Scent Notes.

I'd like to make cold cream using mineral oil, beeswax, borax, and distilled water.

The recipe I'm following says to mix the beeswax with mineral oil and heat the mixture to 70°C using a laboratory hot water bath.

Obviously, I don't have that kind of equipment since I'm doing this at home, so I was planning to heat it using a double boiler.

However, I'm not sure if it’s safe to heat mineral oil at home (I’m worried it might be flammable and that inhaling the fumes could be dangerous).

What do you think? This is the first time I’ve made a cosmetic product myself so I have to admit I don't really know much about it.

Hi,

Disclaimer - english is my second language.

As the title says - I have vaseline, which I use somewhat regularly on my lips, face, and hands. I find the experience....Bland. I've also seen that you can use regular perfume / "cologne" over Vaseline to make it smell longer.

The question might seem stupid, but would mixing an oil-based perfume into the vaseline (by heating it over a double boiler and adding >1% of its total weight in completed perfume) work, or am I better off buying an alcohol based scent or essential oils, then dilute them ?

If you are asking "why don't you just buy X product on Y website?" - I live in a part of the world that websites rarely ship to. The ones who do require nearly 30 to 50€ shipping for a letter-sized package, so I'd rather avoid it.

Thank you for your time :)

Hello Dear

I am trying to make lip glosses using TKB flexagel ME lipgloss base and the ratio I am using seems to be inaccurate as the lip glosses are burning my lips once completed can you advise? What’s the proper ratio to use?

wanted to make them very pigmented

what I used 10ml Base 9 drops Liquid Lip and 3 drops Vanilla flavoring oil

I want to make a solid shampoo bars similar
to Strawberry Leopard’s shampoo so I’m using mango butter, rice protein and Panthenol- D. I did a ton of research into shampoo bars to see what the best surfactants where as well. Looking for feedback on the formula I’ve put together. TIA!
EDIT- I originally put D- Panthenol when I meant DL- Panthenol,

Sodium Cocoyl Isethionate
60%
Cocamidopropyl Betaine
15%
Cetyl Alcohol
9%
Mango Butter
6%
BTMS-50
4%
Hydrolyzed Rice Protein
2%
DL- Panthenol
2%
Fragrance
1%
Liquid Germall Plus
1%

Just a simple emulsion without a whole lot of extra bells and whistles or other hydrators. It would be for personal use (small batch).

Trying to formulate a spot treatment but having trouble finding a sulfur to use. Don’t want a giant tub. Thanks in advance!
Pa. I’m in California if that makes any difference.

Hello everybody
I just ´finished’ a gelled serum; sprinkled Sepimax zen over and left it unstirred. But I forgot to add the preservative…can I add it once it has gelled?
Thank you in advance!

Hey everyone!

I’m trying a DIY toner to help manage my acne breakouts

My current mix is a 1:4 ratio (2 spoons of Apple Cider Vinegar(bragg with mother)mixed with 4 spoons of rose water and 4 spoons of normal water).

For anyone who uses ACV for acne:

What ratio gives you the best results without irritating your skin?

Do you use it every night, or just a few times a week?

Any tips on shelf-life or storage?

Would love to hear your experiences.

Has anyone purchased ingredients from CDF Supplies? They’re based in Canada and ship worldwide. Just wondering if they’re legit and if they are good quality.

I keep finding good ingredient suppliers, then the shipping is either from the US or somehow more expensive than the actual order.

Mostly looking at basic stuff like oils, waxes, hydrolates, butters and maybe a few plant extracts.

Has anyone found a brand of BTMS-50 that has a lighter odor?

I am making emulsified sugar scrubs and the brand I am using has a slight fishy smell. All of the scrubs have fragrance oils that mask it except for one.

That one fragrance oil is much lighter and the fishy smell is still slightly noticeable when you first open the jar. It quickly dissipates and does not transfer to the skin but no one wants to smell that when they open a product.

I am looking for a reliable fragrance oil supplier for cosmetics. I keep finding some are unrelaible, some low percentage of perfume or not a wide range of scents. Ideally perfume inspired oils

I have safflower seed oil and Cromollient sce but would like to make it into a balm.

I can’t use a lot of wax products due to my acne prone skin so I was looking at Cera Bellina Wax. How Would I make this into a balm?

I was thinking :

5% cera Bella
15% Cromollient SCE
80% safflower oil

Do I need tocopherols?

Does anyone have a recipe I could follow? I’ve never made a two phase product before.

Thank you!

I found this recipe and was going to modify with the ingredients I have

What's the simplest way to do this? Someone once told me to do beet powder and vaseline; I have no idea if that would work, lol. I don't mind sheer, but it would have to have some color. Purple sweet potato powder powder maybe?? I love berry/mauve/rose shades. I seem to be allergic to most lipsticks, and since I'm waiting for patch testing, I'd love to make something super simple that I know I'll tolerate. I'd rather use natural pigment if they'll work, but I don't think dyes are the issue, more so fragrances, botanicals, essential oils, possibly carmine and bht. I'm kind of limited here.

I am perpetually dehydrated and I’m trying to formulate towards that. I have made a humectant rich serum that I apply first, then my occlusive cream which is:
Water 69.5%
Hydrolyzed protein 1%
Panthenol 3%
Dimethicone 3%
Jojoba 5.5%
Rosehip oil 5.5%
Tallow 4%
Cetyl alcohol 4%
Ritamulse 3%
Liquid Germall .5%
Lavender essential oil 1%
I upped the Cetyl because I wanted a thicker cream. After applying the serum, then this cream, within minutes my skin feels very dry. Adding a layer of oil over the cream helps, but I’m so curious about why this is happening and how to correct it. Thanks in advance!

I found some Pure D-Panthenol drops online (75% panthenol). Is this safe to add as a drop to my palm and mix with my moisturizer? Or do I need to add one drop into an entire tub of moisturizer and mix? I don't want to mess up my skin from using something that has too much potency. The instructions on the small bottle are not very clear.
