Special use of polyurethane non-silicon silicone oil in cosmetic container making: the scientific secret behind beauty

Introduction: From bottles to beauty, how can technology achieve art?

In today’s era of pursuing beauty, cosmetics have long become an indispensable part of people’s daily lives. Whether applying a lipstick to add confidence or spraying a perfume to show your personality, the use of cosmetics is inseparable from an important part – the container that holds them. Behind this seemingly simple container, there are many unknown high-tech materials and craftsmanship hidden. Today, we will focus on a special material, Polyurethane Non-Silicone Oil, which plays a crucial role in the manufacturing of cosmetic containers.

You may be curious, why such an inconspicuous ingredient is so important? The answer lies in its unique performance. Polyurethane non-silicon silicone oil not only gives the container surface a smooth, mirror-like touch, but also enhances its durability and anti-fouling ability. More importantly, it allows those exquisite designs to be presented perfectly, making every cosmetic container a work of art. Next, let’s uncover this “scientific secret behind beauty” together and see how it transforms ordinary plastic or glass into amazing fashion items through the power of chemistry.

Part 1: Basic knowledge of polyurethane non-silicon silicone oil

What is polyurethane non-silicon silicone oil?

Polyurethane non-silicon silicone oil is a composite material composed of a combination of polyurethane groups and non-silicon oil molecules. Although the name sounds a bit difficult to describe, it is actually a very practical and versatile material. Compared to traditional silicone oil, this material does not contain any silicone elements, thus avoiding allergic reactions that some sensitive populations may have. At the same time, it also inherits the excellent mechanical properties and chemical stability of polyurethane, making it an ideal choice for cosmetic container coatings.

To better understand this material, we can split it into two parts:

Polyurethane (Polyurethane): This is a polymer with excellent flexibility, wear resistance and adhesion. It is these characteristics that make polyurethane widely used in coatings, sealants and various industrial fields.
Non-Silicone Oil: As the name suggests, this is an oily substance that does not contain silicon and is usually made of natural plant extracts or other organic compounds. It has good lubricity and moisturizing effects, while being more environmentally friendly.

When the two are combined, a new material with both functionality and environmental protection is formed – polyurethane non-silicon siliconeOil.

What are its main characteristics?

The following are some key characteristics of polyurethane non-silicon silicone oil that determine its widespread use in cosmetic container manufacturing:

Features	Description
High gloss	can significantly increase the brightness of the container surface and present a mirror-like effect.
Fingerprint resistance	Effectively reduce fingerprint residue and keep the container clean and tidy.
Resistant to chemical corrosion	Expresses strong resistance to alcohol, fragrance and other ingredients in cosmetics.
Environmentally friendly and non-toxic	does not contain silicon, meets strict environmental protection standards, and is safe and harmless to human body.
Easy to process	can be easily mixed with other materials to meet a variety of production process needs.

Advantages of application in cosmetic containers

The reason why polyurethane non-silicon silicone oil can stand out in the field of cosmetic containers is mainly due to the following points:

Aesthetic: It can provide a silky feel to the container while making the surface look crystal clear and attractive.
Durability: Even after long-term use, the container can still maintain its original luster and texture, and is not prone to scratches or fading.
Functionality: In addition to beautifying the appearance, it can also play a certain protective role and extend the service life of the container.

Part 2: Working principle of polyurethane non-silicon silicone oil

How to achieve high gloss?

The reason why polyurethane non-silicon silicone oil can make cosmetic containers exude a charming luster is because its molecular structure contains a large number of polar functional groups. These functional groups can form a tight bond to the container surface, creating a uniformly dense film. This film can not only reflect light, but also block the invasion of external pollutants, thus achieving a dual effect.

In addition, polyurethane non-silicon silicone oil also has a unique “self-healing” capability. When the surface of the container is slightly damaged, this material can restore its original flatness by rearranging the molecular chains, further enhancing its gloss durability.

How are fingerprints removed?

We all know that grease and sweat on the fingers can easily leave traces on the surface of objects, especially on smooth surfaces. However, polyurethane non-silicon silicone oil can solve this problem cleverly. This is because its molecular surface has a special hydrophobic and oleophobic properties that can effectively repel oil and fat components in fingerprints. In other words, even if you touch the container with your hands, there will be no obvious marks left.

Specifically, this anti-fingerprint effect originates from the micro-nano-scale rough structure formed on the surface of the material. This structure is similar to the texture of the lotus leaf surface, which can prevent the liquid from spreading on it, thus achieving the function of “self-cleaning”.

Why is it so chemical resistant?

Cosmetics often contain a large number of complex chemical components, such as alcohol, flavors, pigments, etc., which may cause erosion to ordinary materials. But polyurethane non-silicon silicone oil shows extraordinary resistance. This is because the polyurethane segments inside it are highly crosslinked, forming a solid network structure. This structure is like a barrier, isolating the outside harmful substances and ensuring that the container is always in good condition.

Part 3: Detailed explanation of product parameters

In order to allow readers to understand the specific properties of polyurethane non-silicon silicone oil more intuitively, we have compiled a detailed product parameter list as follows:
