氢氧化钠是一种PH值非常高的强腐蚀性碱，具有一定的危险性，如果不小心沾染到皮肤上，会造成红肿、刺痛等不良的反应，但在制作固体手工皂中，氢氧化钠的应用是非常广泛的，那么使用强碱氢氧化钠做肥皂，是否会对我们的皮肤造成伤害呢?

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、制作肥皂比较简单的化学公式是油脂+氢氧化钠+水生成肥皂+甘油。因此纵然氢氧化钠是强碱，但根据计算后的配方而进行的皂化反应之后，油和碱几乎全生成皂和甘油。

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值比较高的、对皮肤有刺激性的氢氧化钠被分解成脂肪酸钠，也就是皂，从PH值来看，大约在8到9左右，属于弱碱性，使用后，对皮肤没有任何的伤害。不仅如此，弱酸性的皮肤可以用弱碱性的皂调节成中性，再恢复到弱酸性，周而复始，没有影响。

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，还需要我们注意用手工皂是做减法，因为不添加有害化学添加剂，接触不到，因此健康的皮肤会更健康，稍有问题的肌肤，长期使用手工皂会有一定的改善，但是如果是特别敏感的肌肤，或者6个月以下的婴儿，或者是皮肤病患者等，无须用皂，用清水清洁或者遵医嘱。

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，为了使残碱完全皂化，其配方需要合理，清洁力强的油应尽量按照科学的比例使用，而且还要保证皂技术要过关，让皂化更加完全，减少未参与反应的游离氢氧化钠的数量。另外，产品制作后晾皂应在6到8周，等待其完全成熟，这样完全皂化的肥皂，就不会伤害皮肤，让使用者更放心。

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.

使用氢氧化钠制作的肥皂是不会伤害皮肤的，但是要搞根据个人的肤质来选择合适使用的肥皂，这样也不会对您的皮肤产生伤害也可以达到您使用肥皂的目的。更多相关化工产品就来我们网站http://www.jinhao360.com咨询吧！
