Low-Odor Emulsifier Alternatives

It's understandable that you're looking for an alternative to Polysorbate 80 due to its odor. While Polysorbate 80 can sometimes have a characteristic scent, many other emulsifiers are generally low-odor.

You asked about Laureth-23. Laureth-23 is typically odorless when fresh. However, as mentioned in the forum thread, it can develop a pungent odor and change color if it expires or is frequently exposed to sunlight or heat. So, while it's an option, proper storage is crucial.

If you prefer a Polysorbate 80 type but with potentially less odor, you might consider HiPure™ PS80 (Polysorbate 80 Super-Refined). This version undergoes a special refining process to control impurities that can contribute to odor.

Other low-odor emulsifiers suitable for creating oil-in-water emulsions like creams and lotions include:

• Olivem 1000: A natural-derived, non-ionic emulsifier that is PEG-free and generally low-odor.
• Emulsifying Wax 1000: A common non-ionic emulsifying wax (Cetearyl Alcohol (and) Ceteareth-20) that is widely used and typically has minimal odor.

For solubilizing small amounts of oil or fragrance in water, PEG-40 Hydrogenated Castor Oil (Low-Odor) is another option specifically noted for its low odor profile, though its primary function is solubilizing rather than creating stable cream emulsions.

When choosing an emulsifier, consider the type of formulation you are making (lotion, cream, serum, etc.) and the required HLB value, as different emulsifiers work best in different systems.
