In the development of cosmetics, formulation design is crucial, as its scientific and rational design determines product quality and is the core of cosmetic technology. Today, Guangdong Daao Cosmetics OEM Manufacturer summarizes the principles that should be followed and considered in cosmetic formulation design regarding its scientific validity and rationality.

1. Safety First

Cosmetic safety refers to the fact that cosmetics should be non-toxic, non-irritating to the skin and mucous membranes, and non-allergenic. When selecting raw materials for cosmetic formulation design, it is essential to comply with my country's cosmetic hygiene regulations, avoiding or eliminating prohibited raw materials. When using restricted raw materials, their dosage must be in accordance with regulations and must not exceed my country's limits for toxic substances. Safety is a critical quality characteristic of cosmetics.

2. Stability as a Key Focus

Currently, quality problems in cosmetic products within their shelf life mainly manifest in two aspects: firstly, hygiene and safety issues related to microbial contamination; and secondly, stability issues such as water separation, oil separation, layering, sedimentation, discoloration, off-odors, and swelling. The main reason for product instability is often an unreasonable formulation design; therefore, product stability is a key aspect of cosmetic formulation design.

3. Compatibility is Key

Cosmetics sometimes use more than 20 raw materials. Therefore, the compatibility between the components is a key factor in the selection and design of cosmetic formulations. If the components in a formulation have good compatibility, do not react chemically with each other, and even have synergistic effects, the formulation can be considered reasonable. Attention should be paid to the compatibility, incompatibilities, miscibility, and applicable pH ranges of the raw materials.
