Here’s a detailed analysis of Squalane (INCI: Squalane) in sustainable beauty:
Introduction
Squalane is a highly versatile, lightweight, and skin-compatible emollient widely used in sustainable beauty. Known for its moisturizing properties and non-greasy finish, squalane has gained popularity as a clean beauty staple. Derived from olive squalane sourced from natural and renewable sources, it aligns with the eco-conscious values of the modern skincare industry.
1. Identification and Nomenclature
- INCI Name: Squalane
- Common Alternative Names: Hydrogenated squalene
- How to Identify on Product Labels: Look for “Squalane” in ingredient lists, often featured in moisturizers, serums, and oils.
2. Origin and Sourcing
- Natural and/or Synthetic Sources:
Squalane is the hydrogenated, stable form of squalene. Originally derived from shark liver oil, modern squalane is primarily plant-based, sourced from sugarcane, olives, or rice bran. - Geographical Origins:
Major sourcing regions include the Mediterranean for olive-based squalane and Brazil for sugarcane-derived squalane. - Sustainable Sourcing Practices:
Many manufacturers now ensure eco-friendly cultivation, such as organic farming, fair trade olive oil production, or renewable sugarcane practices.
3. Production and Processing
- Manufacturing Methods:
Hydrogenation of squalene into squalane creates a stable, non-oxidizing oil. - Sustainable Production Practices:
Renewable sources like sugarcane and olive oil help minimize the carbon footprint. Advances in green chemistry also reduce energy and water usage during production.
4. Environmental Impact
- Carbon Footprint of Production:
Plant-based squalane has a lower carbon footprint compared to animal-derived sources. - Water Usage and Waste Generation:
Sugarcane-derived squalane often uses sustainable farming techniques that recycle water and minimize agricultural waste. - Energy Consumption in Production:
Hydrogenation is energy-intensive but has been optimized in modern facilities for sustainability. - Biodegradability and Degradation Process:
Squalane is biodegradable and does not persist in the environment. - Ecological Effects:
Switching from shark-derived to plant-derived sources has significantly reduced ecological harm. - Impact on Local Ecosystems and Wildlife:
Sustainable sourcing ensures minimal impact on ecosystems while supporting biodiversity.
