SULFURIZED HYDROLYZED ZEIN.

Insufficient Data / HAIR CONDITIONING, SKIN CONDITIONING

Sulfurized Hydrolyzed Zein is a protein derivative sourced from corn (zein) that undergoes hydrolysis to significantly enhance its water solubility and is further modified by sulfurization, primarily valued for its conditioning properties in cosmetic applications.

Summary

Moisturizer Humectant Skin conditioning

Science

Mechanism of Action

As a hydrolyzed protein, Sulfurized Hydrolyzed Zein functions fundamentally as a moisturizer and humectant, facilitating the skin's capacity to attract and retain essential water. This enhanced hydration contributes to improved skin barrier function. The integral sulfurized aspect is hypothesized to further augment its conditioning capabilities, fostering a smoother skin texture, though detailed mechanistic pathways for this specific modification require further elucidation.

Stability

While native zein exhibits limited water solubility, its hydrolysis significantly improves this characteristic. Zein particles can experience instability and sedimentation around their isoelectric point (pI), typically observed between pH 5.5 and 6.0. Solutions can be stabilized at various pH levels; for example, particles formed at pH 4.0 are stable below pH 5.5, and those formed at pH 9.0 remain stable above pH 6.0. The specific optimal pH for the stability of sulfurized hydrolyzed zein has not been explicitly defined, but improved water solubility post-hydrolysis is a consistent observation.

Not reviewed
Sensitization risk Unknown

There are no specific safety assessments from key regulatory bodies such as the Cosmetic Ingredient Review (CIR), Scientific Committee on Consumer Safety (SCCS), or the U.S. Food and Drug Administration (FDA) for Sulfurized Hydrolyzed Zein. Although CIR has evaluated other hydrolyzed ingredients, these findings do not directly apply to this specific compound. The ingredient is generally listed for skin and hair conditioning without explicit safety references.

Verdict

Insufficient Data

Due to a marked absence of specific clinical efficacy data, comprehensive safety assessments, and detailed skin compatibility insights for Sulfurized Hydrolyzed Zein, its precise role and benefits within precision skincare formulations currently require further dedicated research for a definitive evaluation.
