One of our favorite resources, The Long Hair Community, has posted an excellent list of silicones used in hair care products. There are a couple of technical inaccuracies here and there, but overall this is a very comprehensive list of what you’ll see on the ingredient lists of the products you buy. It’s a bit long, but we thought we’d reprint it here in it’s entirety for your reference. And it took a lot of time to compile this, so a BIG THANKS to the ladies at the Long Hair Community – it’s one of the best non toxic beauty blogs we’ve ever seen!
Silicone Ingredients Used In Hair Care Products

Cyclopentasiloxane (&) C30-45 Alkyl Cetearyl Dimethicone Crosspolymer- Provides a unique feeling during rub-in followed by a soft powdery feel for an extended period. Ideal for cream to powder formulations.
Cyclopentasiloxane (&) Cyclohexasiloxane- Available in three different proportions offering low viscosity, a relatively high volatility and a cyclic structure.
Cyclopentasiloxane (&) Dimethicone- The basis for hair serums. Conditioning without build up.
Cyclopentasiloxane (&) Dimethicone/Vinyldimethicone Crosspolymer- An elastomer dispersion resulting in a smooth, highly viscous gel with a unique silky feel on application.
Cyclopentasiloxane (&) Dimethiconol- Provides a smooth, velvety feel without greasiness. Useful for skincare and hair conditioning.
Cyclopentasiloxane (&) Trimethylsiloxysilicate- Silicone resin blended with Cyclopentasiloxane. Provides water resistance.
Cyclotetrasiloxane- Cyclomethicone D4- A volatile silicone for improving skin feel in applications such as anti-perspirants.
DEA PG-Propyl PEG/PPG-18/21 Dimethicone- Enhances the performance of shampoos and conditioners with improved gloss, manageability and moisturizing properties.
Diisostearoyl Trimethylolpropane Siloxy Silicate- Highly substantive to skin, has good lubricity and spreadability. Compatible with organic oils and waxes.
Dimethicone (&) Laureth-4 (&) Laureth-23- Non-ionic silicone emulsion for 2-in-1 shampoos.
Dimethicone (&) Trimethylsiloxysilicate- Water resistant, non-tacky film, ideal for sun screens.
Dimethicone (from 1 to 1,000,000 cs)- The original silicone ‘oil’. A complete range is available from the highly mobile 1-20 cs, the popular 50-500 cs and the heavier 1,000-1,000,000 cs.
Dimethiconol (&) Sodium Dodecylbenzenesulphonate- An anionic emulsion for leave-in hair products. Disperses well in aqueous preparations and gives the hair good texture.
Diphenyl Dimethicone- A heat-resistant silicone with good film-forming properties. Used as a skin conditioning and anti foaming agent.
Disiloxane- Volatile replacement for ethanol in APs and aerosols.
Lauryl Methicone Copolyol
PCA Dimethicone- Functional over a broad pH range and offers excellent smoothing, conditioning and emolliency properties in many different applications.
PEG/PPG-20/15 Dimethicone- Previously referred to as Dimethicone Copolyol. A very versatile, water soluble polyether modified silicone for use in skin and hair products.
PEG-12 Dimethicone- Previously referred to as Dimethicone Copolyol. A very versatile, water soluble polyether modified silicone for use in skin and hair products.
Phenyl Trimethicone- A very popular high gloss silicone for spray-on hair products. Also provides emolliency and water repellency in skin care products.
Polysilicone-18 Cetyl Phosphate- Color-retaining conditioner for hair products. Also offers thermal protection and a slick, soft after-feel. Excellent solubility and compatibility with most surfactants.
Silicone Resin Spheres (2, 5 & 6 micron)- Fine, white spherical particles give slip and lubricity in pressed and loose powders.
Simethicone- A mixture of Dimethicone and hydrated silica, used as an antifoaming agent. Available in two grades.
Trimethylsiloxysilicate- A solid silicone resin for decorative cosmetics. Provides water resistance.
