Study on moisturizing effect of silicone oil in cream With the continuous development of modern chemical technology, people's requirements for cosmetics are also increasing. Moisturizing, as one of the important functions of cosmetics, has always been a hot topic in research and development. Silicone oil, as a new type of moisturizing agent, has been widely used in the field of cosmetics due to its unique chemical structure and physical properties. This article will introduce the properties of silicone oil, the application of silicone oil in cream, and the impact of silicone oil on the moisturizing performance of cream in detail, with a view to providing reference for researchers in related fields.


1、 Properties of silicone oil
Silicone oil, also known as polydimethylsiloxane (PDMS), is an artificially synthesized organic silicon compound. Its chemical structure consists of alternating arrangement of silicon and oxygen atoms, and side chain modification through methyl groups. This special structure endows silicone oil with many unique properties, making it widely applicable in the field of cosmetics.

chemical stability
Silicone oil has high chemical stability and is not easily reacted with substances such as acids, bases, oxidants, etc. This characteristic enables silicone oil to maintain long-term stability in cosmetics and is not easily spoiled.

Low surface tension
The surface tension of silicone oil is extremely low, which allows it to quickly spread on the surface of the skin, forming a uniform thin film. This layer of film can effectively lock in moisture, prevent moisture evaporation, and achieve moisturizing effect.

Good breathability
Although silicone oil can form a thin film on the surface of the skin, it does not hinder normal breathing of the skin. This is because the gaps between silicone oil molecules are large, allowing air and water molecules to pass through. This breathability allows silicone oil to moisturize without burdening the skin.

lubricity
Silicone oil has good lubricity and can reduce the friction coefficient between objects. This enables silicone oil to be used as a lubricant in cosmetics, improving the product's user experience.


Biocompatibility
Silicone oil has good compatibility with human skin tissue and is not prone to allergic reactions. This characteristic has led to the widespread use of silicone oil in cosmetics, especially in products for sensitive skin.
