I believe @Graillotion was dealing with this some time ago? 

- Put the lipid neat on your hand or face and see how it “shines”. And choose the less “shiny” ones.
- Check for reflective index (I believe that’s how it’s called).
- Try different emulsifiers - e.g. Montanov 202 has mattifying properties for example.

[Paprik]

You are missing stabilising agent/rheology modifier - Try hydroxypropyltrimonium chloride.
What is the final pH of the product?

Other points:
Why do you have Cocamidopropyl betaine in your formula? Should it add some foam?
You are missing antioxidant for the lipids.
Recommended input of Geogard ECT is 0.6 - 1.0%. Stick to the maximum limit please. 

[Paprik]

The formula has more issues than “condensation”.

1. Can you tell me how did you measure the pH?

2. You are using lipids that go rancid very easily, do you think 0.1% of an antioxidant will make sure the product will be fine for more then couple of months? 

3. Not sure why are you using emulsifier, if you are not creating any type of emulsion? 

Finally, what you are experiencing is (most likely) syneresis - Please check polarity of all lipids. I believe Squalane is non (or low) polar lipid, that could cause the issue. Try to remove it, update the formula and try again. 
(you are not supposed to mix polar and non-polar lipids together)

Hope that helps.

Hello,

I don’t think you understood correctly the meaning of this forum. We are helping people to sort formulation issues or discuss things. Not to really teach others. 
Many of us spent hours and thousands of dollars for your education and this seems way to easy to come and ask “How can I formulate this and that”. 
Try to do some research, try to do some products and if it doesn’t work, come back, let us know what seems to be the issue and we can try to help you solve it. 

[Paprik]

Would be maybe good to mention where are you from?

How to make my lotion less greasy

Steric acid 3.86

Vit E 0.75
Preservative 0.9

I you have any  suggestion please do message.

As Perry said, and also you can improve the feeling by using some light esters such as coco caprylate.

I also think it’s to prevent stronger irritation? Wet skin allows product to penetrate deeper. This might cause some irritation to some skins. ?

How long would you keep the iced tea in the fridge? One, two days? That’s cool. If you drink it, your stomach acids will destroy any microorganism. If you leave it for a week, I don’t think you would drink that.  

If you leave a toner for one two days in a fridge, you might not get any microbial growth, but you might. So if you want, you can use it on YOUR skin and see. 
Unfortunately on your skin there is no (hydrochloride acid) stomach acids to destroy any pathogens. 

We can’t stress enough how much preservatives are important.

[Paprik]

Have you thought about Camphor? 

Also, I think you can still incorporate some menthol into your formula. Slightly heat the water with the crystals and gel after. This should stabilize this small input.

Thank you, i asked cus we see all the time commercial moisturizing shampoos based on Shea butter for dry hair and curly hair 

That’s simple marketing mate. They basically add Shea butter in 0.1% and can claim it’s present in the product. No benefits from it tho. You can always add a bit of Polyquat and it will leave the hair with better feel after wash.  

[Paprik]

I would simply stick to Perry’s answer: No.

(Although, I’ve got one video for you

Emulsifier makes an emulsion ~ lotion, cream. 
Solubilizer - alloys you to solubilize a low input of oil in water based product  and keep it clear ~ essential oil in a toner
Cosolvent (solvent) - dissolves an ingredient ~ niacinamide in water.

If you want to do a toner, you will need a solubilizer (water is a solvent). 

Easy enough to google it. 

[Paprik]

Are you just using fragrance or essential oils? 

If you are using essential oils, you should have strong body and base notes. 

If you are using a fragrance, you need to contact your fragrance house and tell them you are looking for something that will linger after wash off. 

[Paprik]

Thanks guys. 

I thought more of tetrasodium EDTA or silimar.

Crack up guys … crack up

Emollients: All good to me.

Humectants: All good to me.

Emulsifiers: 
Coco Glucoside, to me, it’s a foaming surfactant. Doesn’t suit emulsions at all. 
Glyceryl Stearate is mainly for W/O emulsion. It can help with reducing the foaming, but you don’t have any proper emulsifier. Cetearyl alcohol by itself it not sufficient enough. Why you don’t use a high HLB waxy blend + low input of the low HLB GS?
Have you worked with Carbomers before? If you going to adjust pH at the end, no point of having Carbomer in your formula. 

Preservation:
0.1% of Tocopherol won’t be enough probably. Coconut oil has quite good oxidative stability, but still should be protected. Mango butter as well. I would go for 0.4% of the actual tocopherol. (So if you’re using 70% Toco, you would add around 0.6%)
DMDM Hydantoin is an anti-bacterial predominantly with some anti-fungal activity. It really needs to be combined with an anti-fungal to have good, strong broad spectrum activity. (From experiences)

[Paprik]

I usually use chelator everywhere (except obvious formulas such as cationic system, W/O … ).
First of all, I have it on hand (plenty of it and such a small amount is used), it’s cheap and it helps preservative and antioxidant.  

[Paprik]

But if you would ask which one I like more, No. 2 is the answer  

1. usage between 0.75 - 1.5%, pH range 4-8. heat stable “only” to 80°C
2. usage between 0.5 - 1%, pH range <12, heat stable.

[Paprik]

You can’t really tell if the preservative would be sufficient unless you conduct PET (preservative efficacy testing). I’ve never worked with Germall Plus, but did work with Liquid Germall Plus. At 0.5% [Maximum input] I’ve never experienced any growth (at least eye visible - mold, spots, etc … ). If they say Germall plus does not work well in sprayers, I would not go for it. 

If you are home maker, always go for the maximum recommended input. 

Germall Plus is heat sensitive (50°C), do not heat and hold.. If you use clean distilled water, clean equipment etc, you should be fine for cold processing. 

Humectants input - depends. You need to check supplier’s recommended input.
Glycerin - 1- 10% (over 5% will feel sticky/tacky). 
Sodium PCA - 2-5% (more expensive, but high performance, works good with Sodium Hyaluronate)
Propylene Glycol - 1 - 10% (up to 20%?)
Propanediol - 1 -10% (not tacky, I like this one)

and so on. Hope that helps.

Hello, 

please check this link.

Your question is too open, unfortunately we cannot teach you, as most of us spent thousands of hours learning and thousands of dollars for our education.

One thing tho, the purpose of shampoo is to remove oil and dirt. If you want to add oils/butters into your formula, you are basically ruining the purpose. 
Stick to 1% maximum. (That goes for everything from oil phase - antioxidant if you are using plant oils/butters, fragrance, … )

[Paprik]

@Abdullah - Phenoxyethanol’s boiling point is 247°C. So I don’t think this would evaporate (it does have really low evaporation according to google ). About essence, yes, this would probably evaporate. 
To me, even 0.1% of fragrance in my shower gel is too much.

@Perry - Yeah, I’m still naive and think that everyone is following regulations properly.  
 

[Paprik]

This is actually a good point. 

Coca-betaine is usually 30% solids, around 5% salt and water (and possibly preservative?). 
And I found that Disodium Cocoyl Glutamate is also around 30-35% solids, the rest water. 
Na PCA, Glycerin, EDTA are heat tolerant. 

As it’s water thin, is self-foaming pump used for this product?

[Paprik]

Not to question Perry’s guess (God protect me :smiley: ), but he missed the Sodium PCA. 
If Coca-betaine would be 2%, so does must be Na PCA or higher. 

Glutamates don’t foam very well and also don’t thicken with salt. 
However Taurates do foam well and thicken well with salt and as this is water thin, there must be really low input. 

Preservative is probably Biopol PB6 (Methylparaben, Ethylparaben, Propylparaben, Phenoxyethanol) - typical usage 0.5 - 1.4%. 

Disodium EDTA - 0.1?

My guess:
90% Water
3% Disodium Glutamate
2% Glycerin
1% Na PCA
1% Coca-betaine
1% SMCT
1.4% - Preservative
0.6% The rest of the formula. 

Also, only guess.   

[Paprik]

Also, your preservation is not good enough. Phenoxyethanol by itself is not sufficient enough.
