Biodegradable Ether Carboxylic Acid-based Hypoallergenic Detergent Base"BEAULIGHT® LCA-25N"
What's great about ether carboxylic acid type detergent base
"BEAULIGHT® LCA-25N"
1
Hypoallergenic
-As a hypoallergenic detergent, "BEAULIGHT® LCA-25N" is suitable for sulfate-free shampoos, body soaps, etc.
-"BEAULIGHT® LCA-25N" is an ether carboxylic acid that uses a unique narrow ethoxylation technology (*) and has low skin and eye irritation.
*This technology produces ether carboxylic acids with a narrow distribution of ethylene oxide added and low unreacted higher alcohol content.
2
Biodegradable
"BEAULIGHT® LCA-25N" is an ether carboxylic acid surfactant made from naturally occurring alcohols. It is highly biodegradable.
2
Foamability
Even with its weak acidity, "BEAULIGHT® LCA-25N" exhibits good foaming properties and is characterized by a refreshing wash.
4
Hard water resistance
Good hard water resistance.

Performance of "BEAULIGHT® LCA-25N"
Performance comparison chart with CGT (TEA cocoyl glutamate) and SLES (sodium laureth sulfate)
Fig. Performance Comparison Chart
*1 CGT: Cocoyl glutamate TEA
*2 SLES: Sodium laureth sulfate
Hypoallergenic
Compared to CGT and SLES, it is hypoallergenic and gentler on the skin.
Foam height and size
Forms bubbles comparable to those of general anionic surfactants.
Foam viscosity
It shows the same foam viscosity as SLES, and forms moist and glossy foam.
Protein denaturation rate (irritation)
Fig. Protein denaturation rate in each detergent base
*1 CGT: TEA cocoyl glutamate
*2 SLES: Sodium laureth sulfate
Sanyo Chemical's proprietary "narrow ethoxylation technology" allows for use as a cleaning base for shampoos and body soaps with minimal irritation.
Test Method
Protein: 0.05% albumin solution
Active agent concentration: 1.0% aqueous solution of active ingredient
(SLES (sodium laureth sulfate) is measured as a standard)
Bath ratio: albumin aqueous solution/activator aqueous solution = 9/1
Denaturation temperature: 20-25°C x 24 hours
Quantitative method: High performance liquid chromatography (HPLC)
Formula
Protein denaturation rate (%)= {(peak height of blank after 24 hours)-(peak height of sample solution after 24 hours)} / (peak height of blank after 24 hours) × 100
Hard water resistance
"BEAULIGHT® LCA-25N" has good hard water resistance equivalent to SLES (sodium laureth sulfate).
| Surfactant | Hard water resistance (mL) |
|---|---|
| BEAULIGHT® LCA-25N | ≧ 200 |
| SLES (Sodium laureth sulfate) | ≧ 200 |
| CGT (TEA cocoyl glutamate) | 1 |
