It may be stable in that respect, but I am pretty sure you will see a colour and consistency change within a week or two. I believe the proteins break down once in water.
I still don’t understand why those solid surfactants are sooooo expensive. I checked prices in the US as well and still way too pricey. -
And make sure the pH is less than 5.5 or the preservative will be ineffective.
-
It might be stable now, but see how long it lasts.

I just don’t know where to start talking about this idea. It is bad. Badness, madness, incarnate, in fact. Sunscreens need proper formulation and rigorous testing.

I see little difference between these. Shea has a higher melting point and I wouldn’t want to make chocolate from it…

Well, one of them at least is causing your problem. A year is a very long time for saponified soap. Not surprising. I wouldn’t want to sell soap >3 months in age.

@Tyss: First, please ask your own question rather than using someone else’s thread.
Secondly, this phenomenon is well known to soap makers, who call it DOS (Dreaded Orange Spots) — it is caused by breakdown of the soap and usually occurs when oil with a low shelf life is used. Many oils are unsuitable for soap due to this. -
That’s an easy one for a change! This is the edible version, it’s delicious on toast:
In a small heavy saucepan over medium heat, whisk eggs, sugar and lemon juice until blended. Add butter and lemon zest; cook, whisking constantly, until mixture is thickened and coats the back of a metal spoon. Transfer to a small bowl; cool 10 minutes. Refrigerate, covered, until cold. -
Tiny grains of sand? 😮

You’ll have to increase the % of emulsifier until it works, possibly add xanthan gum (0.2%) as stabiliser.

I haven’t found a version of Texapon that has been pearled. I suspect that supplier has added their own pearl to a standard Texapon SLES (EG: N-5, N-5G, or N-70)
Quickpearl PSB3 (Lubrizol)
Another one is Hallstar EGAS.
I add pearl at the end of the mix. -
Lack of shear, I should think.
-
Save yourself a lot of grief and just use one of the standard cold-pearl blends in the manufacturer’s percentage.

Shea butter easily becomes rancid
Not in my experience. Very stable. -
The PEG-7 GC is functionally similar to the Tween-20; you already had 3% of that without causing your current problem. I would try eliminating the Tween-20 and increasing the PEG-7 GC by first 1% then 2% and see what the result is like.

Rather suprised to find a place selling SCS. However, it seems quite expensive at $20 / kg.
Price for SLSA is worse: $50 / kg. in 10Kg tubs.
Can’t imagine the finished cost of a bar at those prices! -
It occurs to me that I might be able to overcome the instability problem of spirulina by using it in a shampoo BAR instead of liquid shampoo.
However, it seems unlikely I will be able to do this; the problem being, availability of solid surfactants. The only one that C. Lar seems to stock is SLS, and I detest SLS for its lousy sensorials (horribly short-flow) and poor flash-foam and irritancy. I’ll investigate but I really doubt it.
Would anyone like to suggest some solid surfactants (not SLS nor SLES) that are among the less obscure ones? I guess I can include cocamide MEA in a recipe. -
There is a definite effect after drying the hair, with Silsense. Slip, shine, and detangling.

We only use organic sodium chloride here, derived from tiny rockpools refreshed by pristine Atlantic seawater, carefully filtered to ensure that no tiny aquatic lives can be lost when dried by the sun.
-
Well, that is a difficult sort of question. It depends how long you make it before use, and so on. Of course, the downside is that you will come to resemble Shaun of the Living Dead.

Why would you want to destroy the foaming capability by adding dimethicone?
-
@johnb - I have to agree. I don’t regard myself as a professional chemist - in cosmetic chemistry I’m self-taught - but even I, as an amateur, am getting annoyed at the constant posts about making non-cosmetic products.

The problem with just bunging in more of that type of thickener is that you’ll end up with pseudo-plastic consistency. It’s not possible to help without knowing what the formula is.

Thank you all for the useful comments.

Interesting. I will try it.
