@johnb in the ASEAN market there exists liquid preparations that are used as peeling toners containing HQ and tret. These can be bought without any prescription from a medical practitioner. I was wondering if this is the same case in the US and in EU.

Hi Gooch. Can you indicate the ingredient list here?

I agree with @Bill_Toge. These two are the most common ingredients for a good water-based pomade. For best info on the restrictions about these ingredients, see links below

had the same experience with beeswax and microcrystalline wax. i’m trying to look now for a supplier of candelilla wax since from reviews this material is said to “melt at skin temperature” and produce a softer wax than beeswax.
-
This looks like a formula for skin moisturizer. Try adding ceteareth-25, PEG-7 glyceryl cocoate and PVP/PMMA crosspolymer to add hold.
-
You might want to look up water soluble silicones. CaresilSCSS 7300, 7301 or 7302 might help.
-
From your ingredients I’m not sure if this is a water based pomade. Yes it contains water but the waxes are too high for it to be considered water based. For the preservative, I swear by Dermosoft OMP for preservative-free claims.
-
Current campaigns against parabens made it harder and harder for formulators to ensure that their product will not be degraded by unseen microorganisms. Phenoxyethanol is one common replacement but this is not enough on its own. Try combined mixtures like Euxyl PE9010 or Dermosoft OMP. These two can be used in a wide pH range too.
-
I agree with you @Belassi. In addition, you have kojic acid dipalmitate which also degrades. Even thought this is a more stable form of kojic acid (which turns yellow in a week), it still turns to an off white after a while.

Try PEG-12 dimethicone, PEG/PPG – 18/18 Dimethicone (and)
Cyclopentasiloxane or PEG-10 Dimethicone. I think Nusil has these water soluble slip agents -
So what exactly are your questions?

Hi Sheng,
Soap-based products indeed have high pH, most at about 9 and above. This high pH is necessary to make the formula produce bubbles. In my country, intimate washes are mostly SLES or non-SLES based, but never soap-based since intimate areas, especially for women, are in the acidic region.
-
@Microformulation thank you for pointing that line out. I’ve been reiterating this countless times. Lots of marketing people declare “chemical-free” products, but come to think of it, even water is a chemical.
-
You might want to try CSS 7300 from Nusil. This worked for us before as water in silicone or silicone in water emulsifier.
-
Hi. Where exactly are you located? I’m from SE Asia, and a lot of manufacturing companies do hair care products here.
-
This highly depends on the pH of your hair color. I experienced using Sodium Lactate - Lactic acid system.
-
You wouldn’t really want dimethicone or other silicones inside your skin. Some silicone types contain volatile components that, when placed inside the body and reaches the bloodstream, may cause serious trouble. I think it is best to use silicones on the epidermis as a carrier for actives and as emollients.
-
Sodium lactate, when added to water, will produce a basic solution due to the formation of the lactate salt. This is different from lactic acid, since adding lactic acid into water will produce an acidic solution, which is very good for keratolytic activity. If you are using sodium lactate, your product will be more of moisturizing rather than keratolytic.
-
Another option you might want to consider is to reduce or remove Polyester-4. I had a hair mask that is almost similar to this one, without polyester-4.
-
Hi @colorier. PVP is what causes the flaking in your formulation. If you want to reduce the flaking, while maintaining the hold and styling capability of PVP, you may try PVP/PA crosspolymer.
-
Hi! You might want to try adding some Glycerox HE by Croda to improve clarity.
-
Silicones are good bubble bursters. If you have the time, you might want to increase dimethicone to improve the appearance of your emulsion.
-
Hi David. I found a definition for food products, but i think this is a good definition of a preservative. Check number 5

Hi Margreat. In my opinion, you should abide by FDA’s regulation in your country. In the ASEAN region, any % of lactic acid can be used as long as the final pH of your product is above 3.00.

Hello everyone,
I’m relatively newbie here, 7+ years doing skin care, baby care, hair care and clinical products. Graduate of BS Biochemistry, and now completing my Masters in Management degree. I may be able to help in formulation, stability, regulatory, qa, and management or marketing issues. And I hope to learn as well from our more seasoned chemists.Please feel free to contact meFollow my blog mcbaysauli.wordpress.com, where I write reviews about products I find worth the promotion.Thank you!
