Isopropyl Alcohol 70% USP Grade

Description

Product Overview

Isopropyl Alcohol 70% USP Grade is a high-purity, volatile, colorless liquid utilized extensively across commercial processing, chemical synthesis, and industrial manufacturing sectors. It is formulated with 70% isopropanol and 30% purified water — providing a specific evaporative profile that makes it highly effective for precise surface preparation and solvent applications. Alliance Chemical supplies this material to meet rigorous quality standards, ensuring consistency for facilities requiring reliable liquid carriers, extraction agents, and compounding ingredients. As an established distributor, we manage a secure supply chain of this critical material within our alcohol collection to support diverse manufacturing demands.

Our USP Grade product is manufactured under strict quality controls to maintain compliance with established monographed standards. This 70% aqueous solution is particularly valued for its balance of solvent power and controlled evaporation rate compared to anhydrous forms. Industrial facilities use it as a raw material in cosmetics manufacturing, skin and hair preparations, perfume formulation, and lacquer solutions. By sourcing from a trusted distributor, commercial buyers receive a reliable technical-grade solvent that performs predictably in automated production lines, cleaning equipment, and specialized laboratory protocols.

Why This Grade

Choosing USP Grade ensures that the material meets specific purity limits for impurities, non-volatile residue, and heavy metals. In precise compounding and chemical formulation, even minute traces of unauthorized organic contaminants can compromise the integrity of the end product or disrupt sensitive chemical reactions. Utilizing a certified USP Grade product guarantees that your production line remains free from unwanted volatile organic compounds and heavy metal contamination that are often present in lower-tier technical grades.

The choice of a 70% concentration over a 99% anhydrous option is critical for applications that require a slower evaporation rate. The 30% water content prevents rapid flashing, allowing the solvent to remain on surfaces longer to complete necessary dissolution or extraction processes. If a facility incorrectly utilizes a 99% concentration where a 70% mixture is required, the solvent may evaporate too quickly, leading to incomplete surface preparation or improper solvation of active ingredients. Alternatively, using an unmonographed industrial grade can introduce unknown impurities, potentially fouling equipment or ruining entire batch runs.

Industrial Applications

• Cosmetic and Personal Care Formulation: Serves as a reliable carrier and solvent in the production of hair preparations, skincare lotions, and specialized cosmetic bases.
• Coatings and Lacquer Solutions: Functions as a diluent and latent solvent to adjust viscosity and improve the flow properties of industrial lacquers and protective coatings.
• Specialized Cleaning Formulations: Utilized in the compounding of window cleaners, industrial cleaning formulations, and surface preparation solvents where rapid, streak-free evaporation is required.
• Extraction and Solvent Carrier: Acts as an effective solvent for extracting botanical compounds, essential oils, and organic resins in commercial processing setups.
• Dye and Ink Dissolution: Used as a low-toxicity coupling solvent to dissolve dyes and pigments in printing processes and textile coloration workflows.

Hazmat & Shipping

Isopropyl Alcohol 70% USP Grade is classified as a hazardous material for transport. It must be shipped under strict regulatory guidelines as UN1219, Hazard Class 3, Packing Group II. The proper shipping name is Isopropanol, and it carries the signal word DANGER due to its highly flammable nature. Our logistics team is fully certified in DOT hazmat protocols, ensuring that all shipments, from individual quarts to bulk pallets, comply with federal transportation laws. GHS classifications highlight its hazards as a highly flammable liquid and vapor (H225), causing serious eye irritation (H319), and potentially causing drowsiness or dizziness (H336).

Proper handling requires strict adherence to personal protective equipment (PPE) guidelines to mitigate these identified hazards. Personnel must wear appropriate eye protection, such as splash-resistant safety goggles, to prevent severe irritation from accidental exposure. Furthermore, because the vapors can cause respiratory tract irritation and drowsiness, operations should always be conducted in a well-ventilated area or under a fume hood. Flame-resistant clothing and chemical-resistant gloves are highly recommended when transferring the liquid to prevent static discharge ignition and skin contact. A comprehensive Safety Data Sheet (SDS) is provided with every order to ensure your team is trained in safe handling procedures.

Handling & Storage

Store Isopropyl Alcohol 70% USP Grade in a cool, dry, well-ventilated facility away from direct sunlight, heat, sparks, open flames, and other ignition sources. Keep containers tightly closed when not in use. This product is compatible with high-density polyethylene (HDPE), stainless steel, and glass containers; avoid storage in certain reactive plastics or unlined metals that may degrade over time. It is highly incompatible with strong oxidizing agents, acids, halogens, and aluminum, as contact can cause vigorous exothermic reactions. Ensure grounding and bonding protocols are followed during bulk liquid transfers to mitigate static discharge hazards.

Order & Documentation

Alliance Chemical simplifies the procurement of high-purity solvents for industrial manufacturing and compounding facilities. We offer flexible packaging configurations ranging from 1-quart bottles to bulk quantities to suit your facility’s operational requirements. Technical documentation, including a Certificate of Analysis (COA) to verify purity and concentration, is readily available to support your quality control compliance protocols.
