-Applications of Cyclopentasiloxane (Cylomethicone) in Personal Care:
The cyclic silicones have a dry feel when applied to the skin for two main reasons.
First, they can lower the surface tension of the formulation, containing oil and thereby leading to a drier-feeling product since they are surface active in oils.

Second, since the cyclics are so volatile, they evaporate rapidly when exposed to the skin’s temperature.
There are several cosmetic applications in which a dry skin feel is essential.
These include antiperspirants, skin serums, and sun-care products.

PRODUCTION AND POLYMERIZATION OF CYCLOPENTASILOXANE (CYLOMETHICONE):
Commercially Cyclopentasiloxane (Cylomethicone) is produced from dimethyldichlorosilane.
Hydrolysis of the dichloride produces a mixture of cyclic dimethylsiloxanes and polydimethylsiloxane.

From this mixture, the cyclic siloxanes including Cyclopentasiloxane (Cylomethicone) can be removed by distillation.
In the presence of a strong base such as KOH, the polymer/ring mixture is equilibrated, allowing complete conversion to the more volatile cyclic siloxanes:

[(CH3)2SiO]5n → n [(CH3)2SiO]5
where n is a positive integer.

D4 and Cyclopentasiloxane (Cylomethicone) are also precursors to the polymer.
The catalyst is again KOH.

However, Cyclopentasiloxane (Cylomethicone) has other properties that boost the effectiveness of formulations.

*Lightweight carrier
Cyclopentasiloxane (Cylomethicone) is an effective carrier, or solvent, due to its ability to evaporate quickly.
Cyclopentasiloxane (Cylomethicone) helps to evenly coat the skin with active ingredients without leaving a heavy, sticky, or tacky residue after application.
Cyclopentasiloxane (Cylomethicone) leaves the active ingredients to work from the skin’s surface as they evaporate.

*Cyclopentasiloxane (Cylomethicone) forms a protective barrier
Cyclopentasiloxane (Cylomethicone) also acts as an emollient that adds a protective barrier to the skin.
However, Cyclopentasiloxane (Cylomethicone) evaporates quickly and does not stay on the skin surface, so it does not leave a sticky feel.

WHY DO WE USE CYCLOPENTASILOXANE (CYLOMETHICONE) IN FORMULATIONS?
Cyclopentasiloxane (Cylomethicone) adds wonderful slip to our products and helps reduce tackiness.
Small concentrations add a really gorgeous, expensive-feeling skin feel.
Higher concentrations of Cyclopentasiloxane (Cylomethicone) help “lighten” products, speeding up dry down/absorption speeds.

Cyclopentasiloxane (Cylomethicone) is commonly used as a diluent in hair oils to create products that don’t leave the hair looking greasy.
A small amount of oil will be diluted in a larger amount of Cyclopentasiloxane (Cylomethicone); when that is applied to the hair the cyclomethicone will readily evaporate, leaving a tiny amount of well-distributed oil behind on the hair.

In cosmetics, you’ll find Cyclopentasiloxane (Cylomethicone) in all kinds of cream cosmetics, where it provides body to the cosmetic and then evaporates readily after application, leaving behind the pigment without any added oil that would compromise wear time.

DO YOU NEED CYCLOPENTASILOXANE (CYLOMETHICONE)?
No, but if you love making cosmetics and/or have hair that is not very tolerant of oils, Cyclopentasiloxane (Cylomethicone) is a wonderful ingredient to have on hand.

REFINED OR UNREFINED?
Cyclopentasiloxane (Cylomethicone) only exists as a refined product.

STRENGHTS OF CYCLOPENTASILOXANE (CYLOMETHICONE):

WEAKNESSES OF CYCLOPENTASILOXANE (CYLOMETHICONE):
The biggest weakness of Cyclopentasiloxane (Cylomethicone) (and other silicones) is all the negative myths about it.
These myths include the idea that silicones suffocate the skin, cause acne, and are bad for sensitive skin.

HOW TO WORK WITH CYCLOPENTASILOXANE (CYLOMETHICONE):
Include Cyclopentasiloxane (Cylomethicone) in the oil phase of your products; it should be cold-processed as it will readily evaporate (and possibly burst into flame) when heated (the flashpoint is 77°C [169°F]).

STORAGE AND SHELF LIFE OF CYCLOPENTASILOXANE (CYLOMETHICONE):
Stored somewhere cool, dark, and dry, cyclomethicone has an indefinite shelf life.

TIPS, TRICKS, AND QUIRKS OF CYCLOPENTASILOXANE (CYLOMETHICONE):
“Silicones… aren’t biodegradable, but they are degradable – they degrade in the environment, and turn back into silica (sand), carbon dioxide and water.”

FUNCTIONS OF CYCLOPENTASILOXANE (CYLOMETHICONE):
*Emollient
Cyclopentasiloxane (Cylomethicone) serves as a non-comedogenic emollient for skin care formulations.
The hydrating properties of Cyclopentasiloxane (Cylomethicone) are excellent for the skin as it traps moisture, making the skin smooth and soft.
Cyclopentasiloxane (Cylomethicone) is used in lightweight products as it does not penetrate the skin but evaporates quickly.

*Color Protection

Rinse-off conditioners containing different types of Cyclopentasiloxane (Cylomethicone) can show an increase in color retention for hair that has been colored.

*Heat Protectant
Protecting hair from excessive heat is a need among many consumers. Hair dryers and other heated appliances first soften the keratin of the hair.
If the devices are too hot, they can cause water in the hair to boil, forming minute bubbles of steam inside the softened hair shaft, weakening the fiber and potentially leading to total fracture.

Cyclopentasiloxane (Cylomethicone) is thermally stable and spreads easily on the hair, forming a protective film to help prevent water loss from the hair shaft caused by the heat of dryers or heated styling tools.
Thus helps guard against damage from heat styling.

*Carrier and Perfume Deliver
Cyclopentasiloxane (Cylomethicone) serves as a prominent carrier for many skin care and hair care formulations.
While being a carrier Cyclopentasiloxane (Cylomethicone) also helps deliver fragrance and gives skin a smooth, non-cooling feel.
