氫氧化鈉是一種PH值非常高的強腐蝕性堿，具有一定的危險性，如果不小心沾染到皮膚上，會造成紅腫、刺痛等不良的反應，但在制作固體手工皂中，氫氧化鈉的應用是非常廣泛的，那么使用強堿氫氧化鈉做肥皂，是否會對我們的皮膚造成傷害呢?

Sodium hydroxide is a highly corrosive alkali with a very high PH value, which has a certain risk. If it is accidentally contaminated with the skin, it will cause redness, swelling, tingling and other adverse reactions. However, in the production of solid hand soaps, sodium hydroxide is widely used. So whether using strong sodium hydroxide as soap will cause harm to our skin?

1、制作肥皂比較簡單的化學公式是油脂+氫氧化鈉+水生成肥皂+甘油。因此縱然氫氧化鈉是強堿，但根據計算后的配方而進行的皂化反應之后，油和堿幾乎全生成皂和甘油。

1. The relatively simple chemical formula for making soap is that oil+sodium hydroxide+water generates soap+glycerin. Therefore, even though sodium hydroxide is a strong base, after Saponification according to the calculated formula, oil and base almost all generate soap and glycerin.

2、PH值比較高的、對皮膚有刺激性的氫氧化鈉被分解成脂肪酸鈉，也就是皂，從PH值來看，大約在8到9左右，屬于弱堿性，使用后，對皮膚沒有任何的傷害。不僅如此，弱酸性的皮膚可以用弱堿性的皂調節成中性，再恢復到弱酸性，周而復始，沒有影響。

2. Sodium hydroxide, which has a high PH value and is irritating to the skin, is decomposed into fatty acid sodium, that is, soap. From the PH value, it is about 8 to 9, which is weakly alkaline. After use, it will not cause any harm to the skin. Not only that, weakly acidic skin can be adjusted to neutral with weakly alkaline soap, and then restored to weakly acidic state, repeating the process without any impact.

3、除此之外，還需要我們注意用手工皂是做減法，因為不添加有害化學添加劑，接觸不到，因此健康的皮膚會更健康，稍有問題的肌膚，長期使用手工皂會有一定的改善，但是如果是特別敏感的肌膚，或者6個月以下的嬰兒，或者是皮膚病患者等，無須用皂，用清水清潔或者遵醫囑。

3. In addition, we also need to pay attention to the use of hand soap as a subtraction method, as it does not add harmful chemical additives and cannot be touched. Therefore, healthy skin will be healthier. For slightly problematic skin, long-term use of hand soap can improve it to some extent. However, for particularly sensitive skin, infants under 6 months old, or patients with skin diseases, soap is not necessary. Clean with water or follow medical advice.

此外，為了使殘堿完全皂化，其配方需要合理，清潔力強的油應盡量按照科學的比例使用，而且還要保證皂技術要過關，讓皂化更加完全，減少未參與反應的游離氫氧化鈉的數量。另外，產品制作后晾皂應在6到8周，等待其完全成熟，這樣完全皂化的肥皂，就不會傷害皮膚，讓使用者更放心。

In addition, in order to make the residual alkali completely saponified, its formula needs to be reasonable, the oil with strong cleaning power should be used in scientific proportion as far as possible, and the soap technology should also be ensured to pass the standard, so that the saponification is more complete, and the amount of free sodium hydroxide not involved in the reaction should be reduced. In addition, the soap should be dried for 6 to 8 weeks after product production, waiting for it to fully mature. This way, the fully saponified soap will not harm the skin and make users more confident.

使用氫氧化鈉制作的肥皂是不會傷害皮膚的，但是要搞根據個人的膚質來選擇合適使用的肥皂，這樣也不會對您的皮膚產生傷害也可以達到您使用肥皂的目的。更多相關化工產品就來我們網站http://www.ileleli.cn咨詢吧！
