What happens if a raw material becomes unavailable?

When a raw material becomes unavailable, a contract manufacturer works to identify a suitable substitute ingredient that matches the original’s function, safety profile, and performance in the formula. In most cases, the product can be reformulated without significant disruption, though some testing and regulatory steps are required. The sections below walk through the most common questions brands ask when facing a cosmetic ingredient shortage.

How does a raw material shortage affect a cosmetic formula?

A raw material shortage directly affects a cosmetic formula by making it impossible to produce the product as originally specified. Depending on how central the missing ingredient is, the impact can range from a minor adjustment to a full reformulation. The severity depends on whether the ingredient is a primary active, a functional base component, or a secondary additive.

If the unavailable ingredient plays a structural role, such as an emulsifier, thickener, or preservative, the entire formula may need to be rebalanced. Removing or swapping out a key component can shift the texture, pH, stability, or shelf life of the finished product. In natural cosmetics, this challenge is often more pronounced because the pool of approved, naturally derived alternatives is smaller than in conventional formulation.

Even when a suitable substitute exists, the reformulated product may behave differently in manufacturing. Processing temperatures, mixing times, and equipment settings sometimes need adjustment. This is why a cosmetic ingredient shortage is rarely just a procurement issue. It touches formulation, production, and compliance all at once.

What causes a cosmetic raw material to become unavailable?

A cosmetic raw material can become unavailable for several reasons, most of which originate outside the manufacturer’s direct control. The most common causes include supply chain disruptions, crop failures, regulatory changes, and supplier discontinuations. Understanding the root cause helps determine how quickly a solution can be found.

Agricultural and environmental factors: Many natural cosmetic ingredients come from plant-based sources. Drought, flooding, pest outbreaks, or poor harvests can sharply reduce the supply of botanicals, oils, and extracts.
Geopolitical and trade disruptions: Import restrictions, sanctions, or logistical bottlenecks can cut off access to ingredients sourced from specific regions, sometimes with little warning.
Regulatory changes: An ingredient can be restricted or banned by regulatory bodies such as the EU’s Scientific Committee on Consumer Safety. When this happens, brands must reformulate regardless of supply availability.
Supplier decisions: A supplier may discontinue a raw material due to low demand, production cost pressures, or business restructuring. This is particularly common with specialty or niche natural ingredients.
Contamination or quality failures: If a batch or ongoing supply of an ingredient fails safety or purity standards, it may be withdrawn from the market until the issue is resolved.

In the natural cosmetics supply chain, ingredient availability is often more volatile than in conventional cosmetics because naturally derived materials are subject to seasonal variation and more complex sourcing requirements.

How do contract manufacturers find a suitable ingredient substitute?

Contract manufacturers find a suitable ingredient substitute by evaluating alternatives based on function, origin, safety data, and compatibility with the existing formula. The process is methodical: first identify what role the missing ingredient plays, then screen candidates that perform the same function, and finally test the reformulated version for stability, safety, and sensory performance.

For natural cosmetics, the search is guided by additional criteria. The substitute must meet natural origin standards, align with any certifications the brand holds, and be ethically sourced. This narrows the field but does not make substitution impossible. A broad raw material portfolio is a significant advantage here. We work with a portfolio of over 500 raw materials, which means we can often propose a credible alternative quickly without having to source entirely new ingredients from scratch.

The evaluation process typically includes:

Identifying the functional role of the original ingredient (emollient, surfactant, preservative, active, etc.)
Screening alternatives with a matching or comparable function and natural origin
Running preliminary lab tests to assess texture, stability, and compatibility
Adjusting concentrations and supporting ingredients as needed
Confirming the reformulated product meets the original performance brief

Ingredient substitution is a core part of how we work with brands, and we treat it as a collaborative process rather than a purely technical one.

Does reformulating with a new ingredient require new safety testing?

Yes, reformulating with a new ingredient typically requires updated safety testing. Under EU cosmetics regulations, any change to a formula that could affect the safety profile of the product must be reflected in an updated Product Information File and, in most cases, a revised safety assessment completed by a qualified cosmetic safety assessor.

The extent of additional testing depends on the nature of the change. Swapping one ingredient for a structurally similar alternative with a well-established safety profile may require only a documentation update. Introducing an ingredient with less regulatory history, or one that changes the product’s pH, preservative system, or overall composition significantly, will likely require more thorough testing.

Key areas that may need review after ingredient substitution include:

Stability testing: To confirm the reformulated product remains stable across temperature and time conditions
Preservative efficacy testing: If the preservative system has changed or been affected by the reformulation
Skin compatibility and safety assessment: To ensure the new ingredient does not introduce sensitization or irritation risks
Claim substantiation: If the original ingredient supported a specific product claim, that claim may need to be reviewed or removed

Working with an experienced contract manufacturer simplifies this process considerably, as they can advise on which changes trigger which requirements and help coordinate the necessary documentation.

How can brands reduce the risk of future ingredient disruptions?

Brands can reduce the risk of future ingredient disruptions by building supply chain resilience into their formulation strategy from the start. This means working with manufacturers who maintain diverse supplier networks, holding safety stock for critical ingredients, and designing formulas with substitution flexibility in mind.

Practical steps that make a meaningful difference include:

Dual sourcing key ingredients: Identifying at least two qualified suppliers for ingredients that are central to your formula reduces dependency on a single source.
Choosing ingredients with broad availability: Where possible, formulating with ingredients that are widely produced across multiple regions or suppliers makes the formula more resilient to localized disruptions.
Staying informed on regulatory developments: Monitoring updates from bodies like the European Commission and SCCS helps brands anticipate ingredient restrictions before they become urgent.
Building a relationship with your contract manufacturer: A manufacturer who knows your product deeply can flag supply risks early and propose alternatives before a shortage becomes a crisis.
Documenting substitution pathways in advance: For critical ingredients, it is worth identifying pre-approved alternatives during the initial formulation phase so that if a disruption occurs, the path forward is already partially mapped.

In the natural cosmetics supply chain, proactive planning is especially valuable because naturally derived ingredients are inherently more vulnerable to external pressures than synthetic ones.

Frequently Asked Questions

How long does it typically take to reformulate a cosmetic product after a raw material shortage?

The timeline depends on the complexity of the formula and the availability of suitable alternatives. For minor substitutions where a functionally similar ingredient is already in the manufacturer’s portfolio, the process can take as little as a few weeks. More significant reformulations that require extensive stability testing, preservative efficacy testing, and a full safety assessment update can take anywhere from two to six months, so early communication with your contract manufacturer is critical to minimizing production downtime.

Can a reformulated product still carry the same certifications, such as COSMOS or Ecocert?

Not automatically. If your product holds a natural or organic certification, any ingredient substitution must be reviewed by the relevant certification body to confirm the replacement ingredient meets their approved ingredients list and origin requirements. In many cases, a suitable certified alternative exists, but the approval process adds time and should be factored into your reformulation timeline. Your contract manufacturer should be able to advise on which alternatives are pre-approved under your specific certification scheme.

What should I do if my contract manufacturer cannot find a suitable substitute for a critical ingredient?

If no suitable substitute exists within your manufacturer’s current portfolio, the next step is to explore whether a new ingredient can be sourced and qualified specifically for your formula. This takes longer and involves additional supplier auditing, safety documentation, and compatibility testing. In some cases, it may be worth evaluating whether the product concept itself needs to evolve, for example by adjusting the format, delivery system, or claim set to accommodate the best available alternative.

Does changing an ingredient mean I need to update my product labeling?

Yes, in most cases. Under EU cosmetics regulations, all ingredients must be listed on the label in INCI order, so any ingredient substitution that adds, removes, or replaces a component requires a label update before the reformulated product can be legally placed on the market. If the change also affects product claims, those must be reviewed and updated accordingly. Your contract manufacturer and regulatory advisor can help identify exactly which label elements need to change and ensure the updated version is compliant before relaunch.

Is it possible to stockpile a raw material to avoid disruptions, and are there any risks to doing so?

Stockpiling is a valid short-term risk mitigation strategy, particularly for ingredients with known seasonal volatility or long lead times. However, it comes with practical considerations: natural ingredients often have limited shelf lives, specific storage requirements, and may degrade in quality over time, which can affect formula performance. A more sustainable approach is to combine strategic safety stock for your most critical ingredients with proactive dual sourcing and substitution planning, rather than relying on stockpiling alone.

How do I know which ingredients in my current formula carry the highest supply risk?

Ingredients with the highest supply risk are typically those sourced from a single geographic region, derived from agricultural crops subject to seasonal variation, produced by only one or two global suppliers, or under active regulatory scrutiny. An experienced contract manufacturer can conduct a supply risk review of your formula and flag vulnerable ingredients before a disruption occurs. This kind of proactive audit is especially valuable for natural cosmetics brands, where the ingredient supply chain is inherently more complex and volatile.

Will consumers notice the difference if a product is reformulated with a substitute ingredient?

It depends on the nature of the substitution. Minor changes to secondary additives or processing aids are typically imperceptible to end users. However, substitutions that affect texture, scent, color, or skin feel may be noticeable, particularly to loyal customers familiar with the product. If a meaningful sensory change is expected, it is worth considering proactive communication with your customer base and updating any product descriptions or claims that no longer accurately reflect the reformulated version.
