FAQ (Frequently Asked Questions)
1. What is LABSA?
LABSA (Linear Alkylbenzene Sulfonic Acid) is an anionic surfactant widely used in the personal care and household cleaning industries. It is known for its excellent foaming, emulsifying, and cleaning properties.
2. What is the CAS number and INCI name of LABSA?
CAS Number: 27176-87-0
INCI Name: Alkylbenzene Sulfonic Acid
3. What are the main uses of LABSA in the personal care industry?
LABSA is primarily used in shampoos, liquid soaps, and facial cleansers due to its strong cleansing ability and foaming properties. It helps remove dirt, oils, and impurities effectively.
4. Is LABSA safe for use in personal care products?
LABSA is considered safe for use in personal care products when properly formulated and neutralized. However, in its raw acidic form, it can be irritating to the skin and eyes, so it is usually converted into a milder salt form, such as Sodium Laurylbenzene Sulfonate, before being used in consumer products.
5. What are the benefits of using LABSA in personal care formulations?
High foaming and cleansing efficiency
Good emulsification properties
Cost-effective surfactant
Biodegradable and environmentally friendly compared to other synthetic surfactants
6. How is LABSA typically incorporated into formulations?
LABSA is usually neutralized with an alkali (such as sodium hydroxide or ammonium hydroxide) to form a sulfonate salt, which is then blended into formulations. It is commonly used in combination with other surfactants to achieve a balanced formulation.
7. Are there any precautions to consider when handling LABSA?
Yes, LABSA in its raw form is acidic and can cause irritation or burns upon contact with skin or eyes. Proper protective equipment, such as gloves and goggles, should be used when handling LABSA. Additionally, it should be stored in a well-ventilated area away from strong oxidizing agents.
8. Is LABSA environmentally friendly?
LABSA is considered biodegradable and has a lower environmental impact compared to some other synthetic surfactants. However, proper wastewater treatment is necessary to prevent any potential aquatic toxicity.
9. Can LABSA be used in sulfate-free personal care products?
No, LABSA is a sulfate-based surfactant and is not suitable for sulfate-free formulations. Alternative mild surfactants, such as glucosides or sulfosuccinates, are preferred for sulfate-free products.
10. Where can I source LABSA for my personal care formulations?
LABSA can be sourced from chemical suppliers specializing in surfactants for the personal care and detergent industries. Ensure that the supplier provides high-purity LABSA suitable for cosmetic and personal care applications.
