Technical Data Sheet on Phenyltrimethicone
Appearance of Phenyl Trimethicone
Structural formula of Phenyl Trimethicone
Phenyl trimethicone is a polymer substance, liquid silicone widely used in cosmetic industry. In
different formulations (not only cosmetic) this silicone serves as an antifoaming agent which inhibits the
formation of foam even if shaking.
On their optical properties (refractive index) is a substance similar to hair. Thanks to this phenyl
trimethicone when applied to the hair instantly increases their brilliance, gives a glossy and well-groomed
appearance. This property is widely applicable in sprays for shine. Besides phenyl trimethicone improves
the hair texture and makes it silky by touch (this effect is particularly noticeable on chemically damaged
hair).
This component additionally provides heat protection properties to cosmetic products for hair.
Phenyl trimethicone is an excellent conditioning component not only for hair, but also for skin. As
the component in cosmetic products it spreads easily over the skin and hair and forms non-greasy and nonsticky film that prevents the loss of moisture from the surface. Therefore, it is used in creams and lotions
for skin, shampoos and hair conditioners (including non-washable conditioners and thermal protection
products for hair.
We should also note that the film of phenyl trimethicone protects the hair and skin from moisture
loss the same as from moisture penetration. This ensures a waterproof effect of some products, such as
sun protection products for hair and skin. It is combined with UV-filters (even dissolves them) and increase
sun protection properties of products (SPF).
The film of phenyl trimethicone, as already mentioned, is impermeable to water, but permeable to gases, so
the skin under such film breathes.
Phenyl trimethicone is included often in composition of antiperspirants wax-, oil- and alcohol based,
where it is used to prevent the formation of white spots.
Phenyl trimethicone in local application is considered to be the safe ingredient and approved for use in
cosmetic industry. Only in very rare cases, this component can cause the allergy.
Phenyl trimethicone is water insoluble, but washed out completely with shampoos containing Lauryl
Sulfate, Laureth Sulfate or Cocamidopropil Betaine.

Brief description
Application in face and body care products
Phenyl trimethicone is used in hair care products,
emulsions and decorative cosmetics. Provides non-oily
skin softening, creates waterproof coating, increases
the SPF of sun protection products. Allows skin to
breathe. Makes hair shiny and soft, protects from heat
(hair dryers). As a component of lipstick makes lips
glossy. Inhibits perspiration.
- used as waterproof component (sun lotions)
- used as active component in sun protection
creams, increases SPF
- used to reduce the tackiness and stickiness in
creams and lotions for the skin (shaving creams
and lotions)
- facilitates a uniform distribution of active
ingredients on the skin surface
- prevents whitening effect of deodorant whitish spots on the skin and clothes
- perspiration inhibitor (reduces perspiration)
Characteristics
- easily emulsified
- good compatible with different cosmetic ingredients
- facilitates mixing silicones and organic components,
which are poorly mixable with each other.
- facilitates introducing in compositions
cyclomethicone and dimethicone to improve the
stability of the product and additional softening.
- provides softening, easily applied on skin surface, no
oil effect
- does not prevent the natural skin secretion through
the soft invisible film
- has good anti-sticking and anti-clumping
performance.
- color and smell free
Recommended concentration for use
To provide noticeable shine use 1% phenyl
trimethicone in hair serum or spray.
Antiperspirants: 5-10%
Hair sprays: 0,5-20%
Sun protection lotions: 2-8%
Hair serums: 1-20%
Creams and lotions: 2-5%

Application as a component of decorative
cosmetics

trimethicone has most glossy effect in
comparison with other silicones)
- provides glossy effect to lipsticks and lip
glosses
- as a component for powdered cosmetics
Application in shampoos, serums,
conditioners
- makes hair shine and soft, facilitates hair
styling
