this Weekend Wonderings post, Brandi and anonymous make this plea: I also would like to know how to make the bubble baths with dls mild or bioterge if you have time.
Can you specify which Bioterge you mean? Is it my old favourite, Bioterge 804?
To be honest, I really hope that I offer enough information on this blog to help you figure out if these surfactants would work in a bubble bath, but let's walk together through the process as we take a look at these surfactants and a bubble bath recipe and see if they will work well together to create a bubbling, lathering, foaming treat! (Check out the surfactants section of the blog or use the surfactant chart as a quick reference!)
DLS MILD or disodium laureth sulfosuccinate
The monoesters of sodium salts - like our friend DLS up there - are the most common sulfosuccinates you'll find. They are considered very mild, with good foaming and detergent properties. Sulfosuccinates are recommended for oily hair as they can remove oil and sebum gently without stripping hair too much, but all hair and skin types can use them without fear of harshness.
Bioterge 804 (INCI: Sodium C14-16 Olefin Sulfonate, Sodium Laureth Sulfate, and Lauramide DEA)
What do we know about these surfactants? Sodium C14-16 olefin sulfonate is mainly used in detergents and syndet bars, as well as shampoos, bubble baths, and body washes. It has great flash foam and good cleansing. It has great flash foam, good lather, and good bubbles.
Sodium laureth sulfate has good foam stability in hard water, good skin tolerance (less irritation), and is easily thickened by salt, Crothix, or glycol distearate. It is also thickened by adding cocamidopropyl betaine. It is considered a mild cleanser (definitely milder than SLS!). It's stable in hard water, but it's not especially great as a bubbler, foamer, or latherer.
Lauramide DEA, like its relative cocamide DEA, is a non-ionic surfactant derived from coconut fatty acids (hence the coca- part) that behaves as an emulsifier, slip enhancer, and re-fattener when included in surfactant mixes. Cocamide DEA can improve the density, body, and stability of foams, so it is a great addition to a bubble bath, but it does not boost foams, and isn't a foaming or lathering surfactant. It is difficult to create a clear product using cocamide DEA, so keep this in mind if you really want a clear product.
If we look at these surfactants, my first thought is that only the C14-16 olefin sulfonate and lauramide DEA would make for a good bubble bath, but you can use any of the bubbling and foaming surfactants to make bubbling and foaming surfactants, so why not try making one with these ingredients?
HEATED WATER PHASE
COOL DOWN PHASE
0.5% to 1% preservative (Germall Plus or Germaben)
2% fragrance oil
Colouring, if desired
Up to 5% Crothix
After you've mixed all the ingredients, allow to come to room temperature, then add up to 5% Crothix or Ritathix DOE 1% at a time. Add, mix, check viscosity, add mix, check viscosity, and so on, until you get the viscosity you want.
To be honest, these aren't the first choices I'd make for a product with these surfactants as they are really lovely cleansers and detergents for normal-oily to oily skin and hair. Consider making facial cleansers or body washes with them.
