However, our recent batches have been very disappointing. The lye seems to be off, when used in soap making, it causes the soap to crumble and doesn’t blend properly, which is a major concern. This inconsistency raises serious safety issues, as improperly reacting lye can make the final product unsafe for skin use. Unfortunately, based on our recent experience, we cannot recommend this product for soap making. ## Frequently Bought Together - AST CaUStic Soda (Sodium Hydroxide) 5Kg Bag - - BioChemixHIPURE Distilled Water 5000ml --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/253340101-ast-caustic-soda-sodium-hydroxide-5kg-bag](https://www.desertcart.pe/products/253340101-ast-caustic-soda-sodium-hydroxide-5kg-bag) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-06-17*
