Color fading in cosmetic tubes is a problem many brands encounter — but often only after products reach the market. What looks perfect at sampling stage may fade, discolor, or transfer color during filling, transportation, or shelf display. For cosmetic brand buyers, this is not just a visual issue, but a packaging risk that affects product quality, consumer perception, and brand reputation.
Common Plastic Coloring Methods Used in Cosmetic Tubes
Plastic cosmetic tubes are usually colored during the manufacturing process. The method chosen directly affects color stability, appearance, and long-term performance.
1. Color Powder Coloring
Color powder can be divided into three main types:
- Inorganic pigments
- Organic pigments
- Dyes
This method is cost-effective but highly dependent on pigment quality and dispersion. Lower-grade pigments may look fine initially, but they often show fading, uneven color, or migration during use, storage, or transportation.
Risk for brands:
Color inconsistency between batches and poor long-term stability.

2. Masterbatch Coloring (Most Common for Cosmetic Tubes)
Color masterbatch is a concentrated pigment blended with carrier resin, then mixed into raw plastic.
This is the most widely used coloring method in cosmetic tube packaging, as it offers:
- Better color consistency
- Improved dispersion
- Easier quality control
However, not all masterbatches are equal. Pigment selection, carrier resin compatibility, and processing temperature all affect final performance.
Key takeaway for buyers:
Masterbatch quality matters more than color appearance at sampling stage.

3. Color Paste (Liquid Color) Coloring
Color paste uses pigments dispersed in liquid carriers.
Advantages:
- Accurate color matching
- Good dispersion for certain designs
Challenges:
Higher sensitivity to processing conditions
Requires experienced manufacturing control
This method is often used for special colors or custom cosmetic tube designs, but it demands a capable supplier.
4. Color Oil Coloring
Color oil is less common in cosmetic tube production and is usually applied in specific industrial plastic applications.
For cosmetic packaging, it is rarely recommended due to limited stability and higher risk of fading.
Why Do Cosmetic Tubes Fade Over Time?
Color fading in cosmetic tubes is not caused by a single factor. It is usually the result of multiple influences combined.
1. Light Resistance (UV Exposure)
Sunlight and UV exposure are major causes of fading.
Outdoor exposure or strong retail lighting accelerates color loss
Dark colors (black, red, deep blue) are more sensitive
Low light-resistance pigments fade faster
For cosmetic packaging:
- Outdoor-use products require higher light-resistance grades
- UV stabilizers can significantly improve color durability
What brands often overlook:
Tube color may pass factory inspection but fade after months on shelves.

2. Heat Resistance During Production
Cosmetic tubes are produced under high temperatures.
Some pigments cannot withstand processing heat
Organic pigments may degrade faster at high temperatures
Materials like PP, PE, and multilayer tubes require different pigment performance levels
If pigment heat resistance is insufficient, color may:
- Change shade
- Become dull
- Fade unevenly
3. Oxidation Over Time
During processing and long-term storage, pigments may react with oxygen.
This is especially common with certain organic pigments, leading to gradual fading.
Poor antioxidant systems or incompatible pigment combinations can accelerate this issue.
4. Chemical Resistance (Acid, Alkali & Formula Compatibility)
One of the most underestimated risks in cosmetic tube packaging is formula interaction.
Cosmetic formulas may contain:
- Alcohol
- Essential oils
- Acids (AHA/BHA)
- Active ingredients
These substances can:
Penetrate the plastic
React with pigments
Cause discoloration, staining, or fading from inside out
Important for brand buyers:
A tube that looks perfect empty may behave very differently once filled.

What This Means for Cosmetic Brand Buyers
From a procurement perspective, color fading is not just a technical issue — it is a brand risk.
Potential consequences include:
- Poor shelf appearance
- Consumer complaints
- Returns from retailers
- Repackaging costs
- Damage to brand credibility
This is why experienced brands increasingly look for solution-oriented cosmetic tube manufacturers, not just low-cost suppliers.
How Auber Packaging Helps Reduce Color Risk
As a professional cosmetic tube manufacturer with global brand experience, Auber Packaging addresses color stability from the start:
- Careful selection of high-grade pigments and masterbatches
- Matching coloring methods to tube material and structure
- Adding UV stabilizers and anti-aging systems when needed
- Conducting light resistance, heat resistance, and compatibility testing
- Supporting brands with application-based recommendations, not one-size-fits-all solutions
- Rather than focusing only on color appearance at sampling stage, Auber helps brands avoid long-term packaging issues throughout the product lifecycle.
