In the ingredient lists of modern skincare and makeup products, you might have come across a string of complex chemical names: "Cyclopentasiloxane & Cyclohexylsiloxane". This sounds rather obscure and difficult to understand, but in fact, it is the "invisible magician" that makes the application of cosmetics more sophisticated, also known as IOTA 345, a type of volatile silicone oil.
Its most notable feature is "refreshing and non-greasy". When you apply lotion or foundation cream onto your skin, it feels smooth like silk, with excellent extensibility. This is all thanks to it. It has excellent spreading properties, which can help the product evenly cover every inch of your skin, even assisting solid pigments in achieving a perfect dispersion in makeup, making the makeup more smooth and natural.
Even more magically, it has "volatility". Unlike ordinary oils, it slowly evaporates after application, removing excess moisture and stickiness, leaving only a dry and soft sensation, with almost no residue. This characteristic makes it a frequent presence in sunscreen, hair conditioner, and deodorant products. It not only has stable chemical properties and can perfectly blend with various components such as alcohol and waxes, but also reduces surface tension and enhances product texture. In short, it is the key ingredient that gives cosmetics a "light and airy spirit", allowing you to enjoy hydration while saying goodbye to heavy burdens.
