Refatting refers to the process of replenishing lipids in the hair or the top layers of the skin, restoring moisture and improving the skin's barrier function. According to lipid composition, refatting agents can be categorized into emollients and occlusives. According to the type of lipids replenished, refatting agents can be categorized into ceramides, fatty acids, and cholesterol. According to the skin or hair type, refatting agents can be tailored to address specific needs, such as dryness, sensitivity, or damage. "Refatting" on ECHEMl mainly supplies raw materials for refatting.

More Information

Refatting agents are components used to replenish lipids lost from the skin or hair due to washing, serving a conditioning function. Cleansing products such as facial cleansers, body washes, and shampoos, while removing oil from the skin, fragments of the stratum corneum, or residues of cosmetics, may also lead to over-cleansing, leaving the skin exposed. Over washing the hair not only dulls its shine but also leads to split ends, dryness, and potential damage to the hair follicles.

Refatting agents can provide a barrier function for the skin, helping to prevent external irritants in facial cleansers or body washes while also moisturizing and smoothing, further promoting the skin's absorption of nutrients. When used in shampoos, they can improve hair conditioning and increase its shine.

Refatting agents include:

•Highly branched saturated or unsaturated alkanes

•Fatty acid esters

•Polyol esters

•Glycerolides

Frequently Asked Questions

What is refatting in the context of industrial chemistry?

Refatting refers to the process of reintroducing fats, oils, or lipid-based compounds into a product formulation—commonly used in cosmetics, pharmaceuticals, and leather processing. This step helps restore natural moisture, improve texture, and enhance skin compatibility by replenishing essential lipids that may have been stripped during prior manufacturing or cleaning stages.

Why is refatting important in cosmetic formulations?

Refatting is crucial in cosmetic products because it helps maintain the skin’s natural barrier function. By adding emollients such as glycerides, fatty acids, or plant-based oils, refatting reduces dryness, prevents irritation, and improves the sensory feel of creams and lotions. This makes refatted products especially beneficial for sensitive or compromised skin types.

What are common refatting agents used in skincare products?

Common refatting agents include natural oils (like jojoba oil, shea butter, and coconut oil), synthetic esters (such as isopropyl myristate), and phospholipids. These ingredients mimic the skin’s sebum, support hydration, and enhance product spreadability. The choice of agent depends on the desired stability, absorption rate, and compatibility with other formulation components.

How does refatting benefit leather processing?

In leather manufacturing, refatting involves applying fatliquors or lubricating agents after tanning to restore flexibility, softness, and durability to the hide. Without proper refatting, leather can become stiff, brittle, and prone to cracking. Effective refatting ensures the final product maintains its aesthetic appeal and functional performance over time.

What should buyers consider when sourcing refatting agents?

When sourcing refatting agents, buyers should evaluate purity, origin (natural vs. synthetic), compatibility with existing formulations, regulatory compliance (e.g., REACH, FDA), and supplier reliability. Certifications like ISO or GMP indicate consistent quality control. Additionally, requesting technical data sheets and sample testing can help verify performance before large-scale procurement.
