Elé Corporation was founded in 1945 near Midway airport in Chicago. We service many industries such as polyurethane (silicone surfactants & catalysts), metalworking, ag, and personal care. Elé manufactures all our products through a variety of processes. We are skilled at alkoxylation and making silicone polyethers. Elé is uniquely positioned to support our customers from inception, thru scale up to full production. A large number of varied sized reactors allow us to cost effectively make from very small MOQs all the way up to bulk. In addition, we have the ability to tailor products to meet customer needs. We are capable and agile.

3. Surfactant Selection
Surfactants vary widely in their irritation potential.
Surfactant Irritation Profile by Charge/Type
Nonionic < Amphoteric < Anionic / Cationic
However: there are mild choices in each category
Careful surfactant choice allows mild formulations without compromising performance
Surfactants vary widely in their irritation potential.
Nonionic (0) are the least irritating, then amphoteric surfactants (+/-). Anionic (-) and Cationic (+) are the most irritating.
Nonionics like the PEL-ALC line, contain:
Ethylene Oxide/EO or Polyethylene Glycol/PEGs and/or
Propylene Oxide/PO or polypropylene glycol/PPG
The more EO/PO, the more mild the surfactant.
If looking to move away from PEGs, Amphoterics are a logical mild surfactant choice

4. Amphoteric Surfactants
Types
Properties
Both positive & negative head charges
Relatively mild
Typically used as secondary surfactants

Compatible with most other PC ingredients
Amphoacetates

Sultaines
Amphopropionates<Amphoacetates<Betaines/Sultaines
Sulfosuccinates<Carboxylates<Isethionates<Taurates<Sulfates

5. PEL-AMPH ALP INCI Name: Arginine Lauraminopropionate Structure:
NEW patent pending amphoteric.
Contains 10% Arginine
Arginine is counter ion to amphoteric molecule ‘lauraminopropionate’
Arginine is 10% and acts as the counter ion to lauraminopropionate

Features/Benefits
Amphoteric
Chloride free
Compatible with wide variety of personal care ingredients

Conditioning
Arginine benefits:
Excellent wetting
Moisture retention
Good foam generation
Improved barrier capacity of outermost skin layer
Very mild

By combining the low irritation potential of an amphoteric surfactant with the soothing and conditioning properties of arginine, an exceptionally mild surfactant is created.
Its benefits include ….(see slide)
Free of claims…(see slide)
The product is about 10% arginine, which provides moisture retention, improves the barrier capacity of skin and is said to promote healing. (we don’t make that a claim)

9. PEL-AMPH ALP (Arginine Lauraminopropionate)
Irritation vs. other Amphoterics
Compared to other amphoteric surfactants at 10% active solutions and pH 7, PEL-AMPH ALP is seen to be very mild both skin and eyes – comparable to imidazoline derived amphopropionates (such as 2CSF-CG on far left) and 2C (middle).
Betaines, in comparison, are primary eye irritants at this concentration.

10. PEL-AMPH ALP (Arginine Lauraminopropionate)
Blender Foam Test
Foam Volume
Surfactant solutions were prepared at 10 ml in deionized water at 25°C. 100 mL of each solution
was placed in an Osterizer and agitated at high speed for 10 seconds.
Initial foam volumes and the level of the foam-water interfaces at 5 minutes were recorded.
The initial foam height produced by ALP was comparable to or better than other “natural” surfactants and nearly as good as cocamidopropyl betaine.
Drainage
Drainage is a measure of foam stability and density.
The number is the location of the foam/liquid interface after 5 minutes.
The lower the number the better.
Here, ALP performed equivalently or better than other tested surfactants.

11. PEL-AMPH ALP (Arginine Lauraminopropionate)
Draves Wetting
Draves Wetting Test
Measures how quickly a surfactant solution ‘wets’ a cotton skein, causing it to sink. Wetting effects how well a surfactant will displace oil from surfaces, how well of a dispersant it will be, and the spreading of formulations.
PEL-AMPH ALP, on the far right is seen to be a superior wetting agent.

12. Excellent Regulatory Profile
Listed on most national inventories

13. PEL-AMPH ALP (Arginine Lauraminopropionate)
Formulation Guidelines
General
Use as secondary surfactant in mild formulations
Add to water phase
Thickening
Like other propionates, does not thicken in response to salt addition
Use polymeric thickening agent(s) such as xanthan gum etc.
Alternatively, combine with sulfate/sulfonate, and amide to thicken by salt addition
PEL-AMPH ALP can be used much the same as other amphoteric surfactants to formulate mild foaming products. It leaves a smooth, soft feel to skin and hair.
Add to water phase with other surfactants.
Like other propionates, it does not thicken in response to salt addition.
It may be thickened using polymeric thickening systems such as cationic guar, xanthan gum, carbomer, etc.
Alternatively, it may be thickened in combination with an anionic surfactant, such as a sulfate or sulfonate, along with an alkanolamide with salt addition.
In combination with an olefin sulfonate and an amphopropionate or amphoacetate, it may be thicken simply by reducing the pH (typically to 5 – 6).

14. PEL-AMPH ALP (Arginine Lauraminopropionate)
Formulation Guidelines (con’t)
Compatible with:
Stability
Anionic surfactants
Best at pH > 5
Cationic surfactants
Protect from freezing
Nonionic surfactants
Store < 30°C
Amphoteric surfactants
Polymeric thickeners/conditioners
Incompatible with:
Oxidizing agents
PEL-AMPH ALP is compatible with most other personal care ingredients.
Avoid using it in the presence of oxidizing agents such as peroxides.
Repeated, or prolonged freezing may cause a precipitate to form.
It may be heated (up to 80⁰C/176⁰F) for limited periods. Prolonged heating will result in darkening.
