神经酰胺 NS

该研究为分子模拟，未涉及眼刺激实验，仅讨论脂质结构对屏障功能的影响，无眼刺激风险数据。

This study is a molecular simulation, not involving eye irritation experiments; it only discusses lipid structure effects on barrier function, with no data on eye irritation risk.

该文献为分子模拟研究，未涉及致敏性评估，仅研究脂质结构，无致敏风险证据。

This is a molecular simulation study, not evaluating sensitization, only lipid structure, no evidence of sensitization risk.

该文献为系统综述，未专门研究CERAMIDE NS的致敏性，且提及CERAMIDE NS与皮肤干燥的关联不一致，未涉及致敏风险。

This systematic review does not specifically study the sensitization of CERAMIDE NS, and mentions inconsistent association with dry skin, no sensitization risk.

超细水滴增加神经酰胺NS水平，改善屏障功能，无经皮渗透风险

Ultrafine water droplets increased ceramide NS levels and improved barrier function, no permeation risk.

神经酰胺NS与皮肤干燥的关联不一致，证据有争议

Association of ceramide NS with dry skin is inconsistent, evidence is mixed.

仅涉及生产方法，未评估经皮渗透风险

Only production method described, no assessment of skin permeation risk.

生理性神经酰胺NS（天然长链）未增加皮肤渗透性，仅短链类似物有促渗作用，故该成分无经皮渗透风险

Physiological ceramide NS (natural long-chain) did not increase skin permeability; only short-chain analogues enhanced permeation, thus no risk for this ingredient.
