the only time you’re likely to need an SDS is for transport purposes
there is no legal requirement for any kind of SDS for end users
the relevant legislation is REACh Regulation 1907/2006, article 2, subsection 6 (page 31 here):
“The provisions of Title IV [concerning SDSs] shall not apply to the following mixtures in the finished state, intended for the final user: […] (b) cosmetic products as defined in Directive 76/768/EEC [now superseded by the regulations]”
-
they do if they’re oil-soluble, but unless it’s a very unusual product they’re not generally necessary
-
what’s in the rest of your formula?
-
actually, thinking about it, unless it’s the standard formula for denatured alcohol as prescribed in Regulation 162/2013 (3% v/v isopropyl alcohol, 3% v/v methyl ethyl ketone, 0.001% w/v Bitrex, alcohol to 100%) it won’t be regarded as denatured alcohol, and you’ll have to pay spirit duty on it
-
in my experience many ingredients lists on this type of product are incomplete and/or just plain wrong, so I’d be tempted to disregard it and start again from first principles
if you don’t already have them, get some samples of different types of waxes, and see if you can get anything similar by combining them
I’d recommend starting with petrolatum, microcrystalline wax, lanolin wax, beeswax and carnauba wax
-
what kind of products are you testing, and what are the results you’ve got so far?
-
I’d suggest adding a hydrophobic liquid (e.g. mineral oil or IPM) to your oil phase - it’ll make the product spread more easily
-
what have you got in your formula?
-
@BeeDumpling folk can’t offer any meaningful advice if what you’re asking is essentially impossible - would you rather be lied to?
because if you do, I know of several consultants who’ll say any old rubbish in return for a sale
-
try cetearyl alcohol; you’ve already got an emulsifying wax in there so it should mix in easily
also, I’d suggest using a 35% solution of peroxide rather than a 60%, as it’s safer and easier to handle
-
what’s it being used for?
-
I’ve said this in other threads, but you cannot have a “chemical-free” product in either a legal or a scientific sense, simply because everything in the product and its packaging is a chemical of some kind; unless of course you want to try selling a vacuum
and dear me… that list is yet more proof that a little knowledge is a dangerous thing
-
@Perry there are quite a few companies out there who didn’t get that memo!
-
it’s very likely that you’re over-shearing the product when you’re add peroxide; there’s not much wax in the formula, and nothing that will help the viscosity recover quickly once it’s been sheared
-
the required HLB would be 5 if you were making a water-in-oil emulsion; what you want is an oil-in-water emulsion, which would have a higher HLB (typically on the order of 10-15)
-
besides the fact there’s no emulsifier (as @cherri said) the large amount of salt is the other cause of separation here; emulsions and salt don’t mix
if you want a water-based hair wax to have a dry texture, you need to use a combination of resins and hard waxes
-
hexylene glycol will thin formulas rather than thicken them - and as there’s no obvious thickener in there, I believe that ingredients list is incomplete
agree with @Zink‘s suggestion of HEC, and I’d add one for xanthan gum too - I’ve seen that used to thicken hydrochloric acid toilet cleaners with a pH of 0 - 1, so it shouldn’t have a problem here
-
if it’s going to have an SPF rating, you’re better off with the nano type
-
the darkening is most likely caused by thioglycolic acid attacking the aluminium, which has led to the product becoming contaminated
thioglycolic acid and metals don’t get on with each other!

@Belassi sodium C14-16 olefin sulphonate is often used as a primary anionic surfactant in US-manufactured toiletries and household cleaners, in the same way that SLES or sodium dodecylbenzene sulphonate is typically used in Europe
at my last place we made an in-house pearliser by dispersing glycol stearate in a mixture of SLES, cocamidopropyl betaine and cocamide MEA; due to limitiations of our plant equipment we couldn’t make very concentrated blends, so it was relatively dilute
I suspect there’s a similar story behind this pearliser
-
I’d use a preservative just to be on the safe side
although high acidity usually inhibits the growth of microbes, there’s no evidence as far as I can see that glyoxylic acid is in itself microbistatic or microbicidal
-
@mikethair at that pH, your customers could also use it to get their dishes sparkling clean
-
if you want to make it opaque and white, try adding an opacifier like Acusol 301/Opulyn 301; it’ll make the bulk more uniformly white than a pearliser will
-
the presence of sodium olefin sulphonate would suggest it originates somewhere in the Americas; it’s commonly used in the US but very hard to come by in Europe
