Why add silicone in foundation?

As cosmetic technology has advanced over time, the foundation(water-based foundation) has evolved to become an integral part of modern makeup. It not only evens out skin tone and covers imperfections, but also enhances the skin's texture for a flawless look. Silicone is used in many products, such as silicone primer, and silicone foundation. Why are silicones added to foundations?

Silicone shows significant benefits in foundations. Different from silicone-free products, their unique lubricating and softening properties make water-based foundations easier to apply and cover the skin evenly, minimizing the appearance of powdery and flaky skin. At the same time, silicone can form a protective film on the surface of the skin, locking in the color of the makeup, prolonging the durability of the makeup, and making it more vivid and long-lasting. In addition, its mild nature has low irritation to the skin and is suitable for all skin types, bringing lightweight and burden-free comfort. Therefore, the application of silicone ingredients in the foundation not only enhances the product experience but also makes the makeup more perfect and long-lasting.

The advantages of adding silicone are introduced in the following five aspects

1. What are the requirements for foundations?

In modern society, consumers' requirements for foundations are becoming more and more diversified and strict. A good foundation not only needs to have good coverage and a long-lasting makeup effect but also needs to meet the following requirements:

(1) Natural fit: The foundation should fit closely with the skin to avoid floating powder or makeup removal phenomenon so that the makeup looks natural and flawless.

(2) Lightweight and breathable: To avoid bringing a heavy feeling to the skin, to ensure that the skin can breathe freely, to prevent clogging pores.

(3) Comfortable Skin Feeling: Smooth and delicate touch, non-greasy, non-dry, bringing a pleasant experience.

(4) Long-lasting waterproof: Water-based primers can maintain the integrity and stability of the makeup under various environmental conditions and are not easily affected by sweat or moisture and fall off.

(5) Safety: All ingredients should meet safety standards, have no stimulation, and no allergy risk, which is suitable for all skin types.

2. What silicone ingredients are added to the foundation?

Typically, the combination of base materials is highly stable and rarely causes other problems. When we apply a layer of foundation to the face and then push it evenly onto the face, the water slowly evaporates, and the whole process is brief, taking about a few minutes. Then, the film-forming agent added to the foundation can start to form a film in the range of minutes to tens of minutes. Consumer's favorite silicone-based primers foundation adheres well to the toner, making it a strong mesh that prevents puffing and makeup removal.

Generally, silicone is used as a film-forming agent for foundation. The reason for this is that whether or not the "powder" has been treated well, it may move around after it is applied to the face. Different from silicone-free products, with a silicone ingredient that is a "film-forming" agent, the "powder" is held in place.

It (Silicone MQ resin) is a solid silicone resin powder with good film-forming properties, which provides excellent water resistance by forming a soft touch and can be used in a wide variety of skin care formulations. It can be applied to color cosmetics (lipsticks, lip glosses, eyeliners, BBs) and more.

By compounding Trimethylsiloxysilicate with different silicone oils, it is possible to obtain film-forming agents with different solution types.

Many people think that the mixed silicone will "smother" acne, but "silicone" materials theoretically do not smother acne, on the contrary, the skin feels should be very good - this is the reason why these products are preferred by oily skin. In fact, these products also include a large amount of "volatile silicone oils", which are also silicone but are intended to make them easier to use for newcomers.

"Volatile silicone oils are a type of silicone material that is particularly "light" on the skin. A product that contains a lot of "volatile silicone oils" is comfortable to push off. These "volatile silicone oils" provide a good "spreading sensation" when they are applied, and once they are spread, they "evaporate" and disappear into the air, which ensures the "film formation" that was just described. This can ensure the "film formation" and let the "powder" in the "film" above the "place".

3. What is the formulation of the foundation?

In order to ensure the skin-friendliness and makeup-holding effect of the foundation, most of the common foundations on the market are "oil-in-water" formulation systems.

An external phase for the "oil", the internal phase for the "water" emulsion, the formula framework system for the "W / O" emulsion system, W / O-type foundation formula framework can be divided into four parts: oil phase W/O type foundation formula framework can be divided into four parts: oil phase, powder phase, water phase, other.

Oil phase: 

Silicone oil, common oils, and fats, etc.

Powder phase: 

Color powder; silica, mica, and other fillers to help stabilize the powder class.

Water phase: 

Including water, polyol, salt, magnesium sulfate, and other low-temperature stabilizers.

Other: 

Anticorrosive phase, flavor, etc.

4. What are the advantages of silicone?

(1) Enhancement of texture and spreadability

Silicone-based primer significantly improves the texture and spreadability of foundations with their unique lubricity and softness. While conventional foundations are often difficult to apply and prone to snagging or floating, foundations with silicones are smoother and easier to apply. Silicone can form a uniform, delicate film on the skin surface, making the foundation fit the skin better, reducing resistance when applying, and realizing seamless coverage, making the makeup more natural and flattering.

(2) Enhanced durability and stability

Durability is one of the most important indicators of foundation performance. Silicones can form a protective film on the skin's surface, effectively locking in the color of makeup and prolonging its durability. This means that silicone-based foundations stay brighter and more intact for longer, and are less likely to fade or smudge. Whether in hot summer or humid environments, it ensures long-lasting makeup and keeps beauty on the line all day long.

(3) Improved skin feel and breathability

Silicone foundations have good compatibility with the skin, giving foundation products a light, unburdened skin feel. It does not clog pores, allowing the skin to breathe freely and avoiding the suffocating feeling that traditional foundations can bring. At the same time, the hydrophobicity of silicone also ensures that the foundation does not easily come off when exposed to water or sweat, keeping the makeup neat and fresh.

(4) Excellent water and sweat resistance

For consumers who need to maintain their makeup for a long time, waterproof and sweatproof performance is particularly important. Some specific types of silicones have excellent water and sweat resistance, especially for makeup products such as foundations. They can ensure that the foundation remains intact under the influence of sweat and moisture, and is less likely to smudge or fall off, making the makeup more durable and stable.

5. How to make the foundation perform better?

A silicone-based foundation is more competitive in the marketplace and meets consumer demand for high-quality, long-lasting, and safe beauty products. Silicone-based primers significantly improve the feel, spreadability, and stability of the product, making it easier to spread and absorb on the skin, and providing a more comfortable application experience.
