Poloxamine 1307

What is Poloxamine 1307?

Poloxamine 1307 is a synthetic, non-ionic block copolymer featuring four arms of polyethylene oxide and polypropylene oxide chains linked to an ethylenediamine center, forming a star-shaped structure. Developed for pharmaceutical and cosmetic applications, it belongs to the poloxamine family, valued for its amphiphilic nature that allows interaction with both water and oil phases. In skincare products like shampoos, body washes, micellar waters, lotions, and sprays, it functions by reducing surface tension at interfaces, which disperses oils, stabilizes emulsions through interfacial film formation, and creates molecular solutions for hydrophobic ingredients in aqueous bases. This enables the production of clear, homogeneous formulations with consistent texture and performance, commonly used in rinse-off cleansers and leave-on emulsions at low levels for mild action.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.
Solubilizing agent
Helps incorporate oils and fragrance into water-based formulas by forming micro-solutions, enabling clear sprays, toners, and micellar products.

Benefits

Facilitates stable oil-in-water mixtures for smooth, non-separating lotions and creams.

Dissolves fragrances and oils into clear water-based toners and sprays.

Promotes gentle cleansing and foaming in washes without heavy residue.

Who It's For

Who May Benefit Who Should Avoid
Individuals seeking non-comedogenic formulas for acne-prone skin.
Those with known sensitivity to polyether polymers.
Users of micellar or foaming cleansers preferring mild surfactants.
Individuals experiencing reactions to similar non-ionic surfactants.
People wanting stable, clear products like toners or body mists.
People preferring entirely natural or plant-derived ingredients only.

Safety Notes

  • Considered low hazard in cosmetic use based on safety assessments.
  • Non-comedogenic, unlikely to clog pores in typical applications.
