Sustainability has become a major driver of consumer behavior. In the UK alone, 75% of adults say they actively try to act in ways that are not harmful to the environment, a mindset that is strongly influencing purchasing decisions in the cosmetics sector.
As a result, natural, waterless and low-waste formulations are gaining momentum year after year. In this context, solid cosmetics are emerging as an attractive alternative, offering tangible solutions to reduce packaging waste, lower transport emissions and extend product shelf life.
Solid Cosmetics: Designed for Waste Reduction
One of the most compelling advantages of solid cosmetics lies in their minimal environmental footprint.
Because they are often anhydrous, solid products typically require little to no plastic packaging. They are frequently sold:
- Without packaging (“naked” products)
- Or with simple primary packaging made from recyclable paper or cardboard
Their high concentration of active matter significantly reduces product volume, which in turn lowers the carbon footprint associated with storage and transportation.
The absence of water also simplifies formulations. Ingredients such as:
- Preservatives
- Chelating agents
- pH regulators
- Certain texturizers
often become unnecessary, allowing formulators to reduce the total number of raw materials while maintaining product integrity.
Solid Beauty: More Than Just a Trend
The rise of solid cosmetics is not solely driven by environmental concerns. For many consumers, it reflects a return to simplicity and authenticity, echoing ancestral beauty rituals such as traditional soap use.
Solid products evoke:
- A sense of safety and minimalism
- Emotional connections to childhood and play
- A slower, more mindful skincare routine
Consumers enjoy discovering new application gestures, watching products evolve over time and actively participating in their conservation. These emotional dimensions foster stronger attachment and brand loyalty.
Few Galenics, Endless Applications
Formulating solid cosmetics relies on pure powdered ingredients or naturally anhydrous raw materials such as butters, oils and waxes. Two main galenic forms can be identified:
Powder forms
- Loose powders or compressed tablets
- Often cold-processable
- Commonly used for cleansing and absorption
- Typical applications: dry shampoos, facial cleansers
Bar forms
- The most widely used galenic
- Generally obtained through hot-process manufacturing
- Suitable for cleansing and emollient applications
- Typical products: shampoo bars, massage bars
Although these galenics may appear limited, recent years have seen a surge in innovation. Once confined to soaps and shampoo bars, solid cosmetics now include:
- Perfume
- Make-up
- Deodorants
- Toothpaste
Are Solid Cosmetics the Ultimate Solution?
Despite their many benefits, solid cosmetics do not yet meet all consumer expectations.
Growing feedback highlights challenges such as:
- Skin or scalp irritation
- Lack of long-term efficacy
- Greasy or heavy sensory profiles
Because solid products are undiluted, misuse or poor formulation can lead to localized over-application of certain ingredients, such as surfactants, potentially causing dryness or irritation.
Additionally, many humectants and anti-aging actives are water-soluble, meaning solid skincare formulations cannot easily leverage their moisturizing and age-defying benefits.
Innovation Is Key to Overcoming Challenges
Innovative formulation strategies are helping to address these limitations, as demonstrated by advanced solid concepts such as:
- Black Delight Cleansing Formula
(Clariant, Nouryon) - Gentle Shampoo Bar “Keep Calm”
(Ichimaru Pharcos, Sabo, Aprinnova, Nouryon)
These examples illustrate how ingredient selection, sensorial balance and formulation precision are essential to delivering performance comparable to traditional cosmetics.
A Promising Future for Solid Cosmetics
Solid cosmetics are still in their early stages, but their future is undeniably bright. They represent one of the most effective approaches to conserving resources and reducing environmental impact in the beauty industry.
However, their rapid and recent expansion brings challenges related to sensoriality, efficacy and consumer experience. While the formulation process may appear simple, success depends on carefully chosen, high-performance ingredients.
With the right expertise and innovation, solid cosmetics have the potential to become a permanent and trusted part of consumers’ daily routines.
