Cruelty-Free Moisturizer Certification: Active Ingredient Review

Moisturizers constitute the broadest and most widely used product category in the cosmetics industry. This range—which spans from face creams to body lotions, and from hand creams to eye care products—also represents one of the most complex areas of audit for cruelty-free certification. Due to their high water content, multi-ingredient nature, and emulsion-based structures, moisturizer formulations both expand and complicate supply chain verification. In this article, we examine the functional ingredient groups specific to moisturizer products and the certification requirements associated with each group at a technical level.

Scope of Certification and Category-Specific Position

Cruelty-free moisturizer certification is an independent endorsement that verifies that no ingredient used in a moisturizer’s formulation is of animal origin and that no animal testing was conducted at any stage of the production process. Since this certification is evaluated within the skincare products category, it falls under the general framework of cosmetic certification but includes certain additional category-specific requirements.

Moisturizer formulations contain between 60 and 90 percent water by weight. This high water content necessitates the use of preservative systems to maintain the product’s microbiological stability. Additionally, emulsifiers are required to keep the water and oil phases mixed together. These two structural requirements make moisturizer formulations multi-ingredient and expand the scope of supply chain verification. A typical moisturizer contains between 15 and 30 different ingredients, and a separate test history declaration must be collected for each of these ingredients.

Functional Ingredient Groups and Audit Requirements

The ingredients in a moisturizer formulation are divided into different groups based on their functions. Each group requires a specific audit approach within the cruelty-free certification process. Below, we discuss the most common functional ingredient groups found in moisturizers and the requirements associated with these groups.

Moisturizing Actives

Moisturizing actives are the ingredients that perform the product’s primary function. Glycerin, hyaluronic acid, panthenol, urea, and amino acids fall into this group. Some of these actives may be derived from both plant and animal sources.

Glycerin is perhaps the most common ingredient in moisturizing formulations and can be derived from both plant oils and animal fats (particularly lard and beef tallow). During the certification process, the plant-based origin of glycerin must be verified through a supplier declaration and, if necessary, isotope analysis. Hyaluronic acid is traditionally derived from rooster combs, but plant-based versions produced through microbial fermentation are now common. The manufacturer must document that the hyaluronic acid used is fermentation-derived.

Emollients and Oils

Emollients are ingredients that form a film on the skin’s surface to reduce moisture loss and soften the skin. Plant-based oils (jojoba, shea, coconut, olive oil), synthetic esters (isopropyl myristate, caprylic/capric triglyceride), and silicone derivatives fall into this category.

Within this group, the most critical ingredients in terms of cruelty-free certification are animal-derived oils. Lanolin is a natural wax derived from sheep’s wool and is used as a highly moisturizing agent in many moisturizers. Because lanolin is of animal origin, it is not accepted under cruelty-free certification. Similarly, beeswax, cholesterol, and animal-derived squalene are also evaluated under this category. Plant-derived squalane (derived from olive oil or sugarcane), however, is considered safe.

Emulsifiers

Emulsifiers are ingredients that ensure water and oil phases remain in a homogeneous mixture. Emulsifiers such as lecithin, cetyl alcohol, stearic acid, polysorbates, and glyceryl stearate are commonly used in moisturizer formulations.

Lecithin can be derived from both soy and egg yolk. The use of soy-derived lecithin in moisturizers must be documented by a supplier’s declaration. Stearic acid and cetyl alcohol, on the other hand, can be of either plant-based or animal-based origin. It must be clearly verified that these ingredients are plant-based (typically derived from palm or coconut oil).

Preservative Systems

Preservative systems are used in moisturizers with high water content to prevent microbial spoilage. Phenoxyethanol, parabens, sodium benzoate, potassium sorbate, and organic acids fall into this category.

These preservatives themselves are not of animal origin, but it must be documented that no animal testing was conducted during their production processes. Additionally, some preservative systems may be supplemented with naturally derived ingredients (such as chitosan or lysozyme). Chitosan is derived from the shells of shellfish and is of animal origin. Lysozyme, on the other hand, is derived from egg whites. The use of these ingredients in a moisturizer formulation prevents it from obtaining cruelty-free certification.

Thickening Agents and Excipients

Ingredients used to regulate the consistency, flow, and texture of moisturizers include xanthan gum, carbomer, cellulose derivatives, and polyacrylamide. The vast majority of these ingredients are synthetic or plant-based and contain no animal-derived ingredients.

However, in some cases, animal proteins such as gelatin, collagen, or elastin—used as texture modifiers—may be added to the formulation. These ingredients are commonly found in moisturizers that make claims such as “anti-aging” or “collagen-boosting.” During the certification process, such claims must be reviewed, and it must be verified that the formulation does not contain animal proteins.

Evaluation Criteria Related to the Production Process

In cruelty-free certification for moisturizers, the production process is evaluated not only based on the ingredients used but also on production methods and facility conditions.

Structure of the Certification Process

Cruelty-free moisturizer certification consists of sequential stages, each of which is evaluated independently. The process begins with the manufacturer’s application and concludes with the issuance of the certification decision.

During the application stage, the manufacturer submits its product portfolio, a list of all ingredients used, and a supply chain map to the certification body. At this stage, the product category and potential risk areas are identified. In the second stage, supplier declarations are collected and verified for each ingredient. Additional verification is conducted for dual-source ingredients such as glycerin, lecithin, stearic acid, and hyaluronic acid.

In the third stage, the collected documents are reviewed for completeness and consistency. If any missing or conflicting declarations are identified, supplementary information is requested from the manufacturer. The fourth stage involves an on-site audit of the production facility. During this audit, production lines, water treatment systems, emulsion preparation processes, and quality control records are examined. In the fifth and final stage, all findings are evaluated, and a final decision is made.

Certificate Validity and Continuity Conditions

The cruelty-free moisturizer certificate is valid for one year. The manufacturer’s compliance obligations continue throughout the certificate’s validity period. During the annual renewal process, the manufacturer is required to submit updated ingredient declarations, production records for the past year, and, if applicable, documentation regarding formulation changes.

If a new moisturizer is added to the product portfolio, it cannot be included in the scope of the certificate until its ingredient declarations are approved. If the supplier of an existing ingredient changes, the new supplier’s declaration must be submitted to the certification body. The certified manufacturer is expected to adhere to the ban on animal testing and the principle of not using animal-derived ingredients in all production activities covered by the certification.
