$BELSIL<sup>®</sup> PDM 20

BELSIL® PDM 20 is a phenyl-modified polydimethylsiloxane characterized by having a higher refractive index than dimethicone fluids (1.38-1.40). It offers clear advantages over dimethicones with regard to skin feel, shine and compatibility with other cosmetic raw materials.

  • INCI Trimethylsiloxyphenyl Dimethicone

BELSIL® PDM 20 is used in all kinds of cosmetics formulations, but mostly in Hair Care compositions and Color Cosmetic due to their shine-enhancing benefits. BELSIL® PDM 20 reduces the stickiness of formulations containing acrylic acid polymers. It is an excellent emollient in skincare products, imparts a very pleasant feel to the skin, and provides water-repellency. In antiperspirant formulations, phenyl-modified silicones are employed as a refractive-index match to promote the formation of clear products.



The 'Best use before end' date of each batch is shown on the product label.

Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
