This ingredient is considered safe as used in cosmetics.
Silicones, chemically more precisely poly(organo)siloxanes, is a designation for a group of synthetic polymers in which silicone atoms are connected through oxygen atoms.
The volatility and viscosity are determined by the chain length.
The silicones include various compounds which contain as a characteristic functional group a polyorganosiloxane.
Important classes are: dimethylpolysiloxanes, phenylmethyl polysiloxanes, cyclic methylsiloxanes and siloxanes modified with alkyl groups or PEG (polyethylene glycol).
Silicones are water insoluble and have a low surface tension.
The low surface tension is the reason for their good spreading quality; they constitute protective films on the skin which are vapor-permeable.
They have no comedogenic effect and are particularly well tolerated on skin. Because of their favourable technological and cosmetic properties they are used rather frequently in cosmetics and serve for the improvement of care properties in skin and haircare products.
Stearyl Dimethicone improves the texture of products, giving them a silky and non-greasy feel, which is often preferred by consumers.

Stearyl Dimethicone conditions both the skin and hair, helping them retain softness, smoothness, and manageability.
It also offers some degree of heat protection for the hair, preventing damage from high temperatures due to styling tools like straighteners, blow dryers, and curling irons.
One of the primary ways stearyl dimethicone works is by forming a protective layer on the skin or hair.
The long stearyl group (fatty alcohol chain) helps to make the silicone more compatible with skin and hair, improving its ability to adhere and create a smooth surface.
This layer acts as a moisture seal, preventing water loss (called trans-epidermal water loss) and protecting against environmental stressors such as pollution, UV rays, and harsh weather.
For hair, this means reducing frizz and locking in hydration, while for skin, it helps retain moisture and prevent dryness.
Stearyl Dimethicone is lipophilic (oil-attracting), which makes it an excellent ingredient for enhancing the spreadability of products.
Whether in lotions, serums, or hair care products, it ensures that the product glides smoothly onto the skin or hair, providing even coverage without tugging or pulling.
This feature is particularly useful in products like foundations, primers, or moisturizing creams where uniform application is key.
Despite being a silicone, stearyl dimethicone is often praised for its non-greasy and non-sticky finish.
This makes it suitable for use in products designed for those with oily or combination skin, or individuals who do not like the heavy, greasy residue that some emollients can leave behind.
In hair care, stearyl dimethicone smooths the hair cuticle and helps manage frizz by preventing moisture from entering the hair shaft in humid conditions.
