Technical Details & Test Data
- Evaluation of Skin Irritation
- Skin irritation can be evaluated by assessing Trans-Epidermal Water Loss (TEWL) which increases when skin is damaged by physical or chemical factors
- Post Occlusion Stress Test (POST), places test material under an aluminum occlusion patch for 24 hours before measuring TEWL over 5 min
- Testing was carried out comparing nonwoven treated only with surfactant vs nonwoven treated with surfactant and skin care additives
- Alongside this testing, Laser Doppler readings were taken to measure skin irritation from blood perfusion
Irritation Mitigation Panel Study - TEWL
A 30% reduction in TEWL was measured when treating nonwoven fabric with Cirrasol Protect at 2% w/w
Irritation Mitigation Panel Study – Laser Doppler
-
48% lower inflammation was measured when treating nonwoven with Cirrasol Protect at 2% w/w compared to the control
-
77% of participants showed a lower change in inflammation using Cirrasol Protect
- The Wet Friction Problem
- Friction is a common source of irritation from fabrics in contact with the body
- Irritation is often exacerbated by the addition of moisture:
- Moisture in itself can be an irritant
- Water significantly increases the amount of skin/nonwoven friction
-
High performing hygiene finishes are one method of controlling the moisture, but this only manages part of the problem
Assessing Skin/Nonwoven Friction
- In order to asses wet and dry friction, a polyolefin based synthetic skin was pulled across a sample of treated nonwoven
- Lloyd LRX Tensile Tester was used to measure force required to move the skin across the treated nonwoven fabric
- Once dry friction was established, 0.2g of deionised water was evenly distributed across the sample to simulate very slight wetness of a hygiene product
Friction readings were then repeated on the moist fabric
Friction Results on 15 gsm PP Nonwoven
Friction Results at Different Treat Rates
- All samples were treated at 0.5% hygiene finish and 2% Cirrasol Protect
- Measurable friction reduction effect from Cirrasol Protect both dry and when wet
- Up to 70% reduction in friction on some nonwoven/finish combinations
Cirrasol Protect gives consistent performance improvements when used with Cirrasol Care or competitor hygiene finish
- 0.5% Cirrasol Care and varying quantities of friction additive, tested on 13 gsm PP nonwoven
- Treat rate of 1% or 2% Cirrasol Protect gives improved performance for friction reduction for both products when wet and when dry
- Treat rate of 0.5% gives no measurable friction reduction compared to untreated fabric
- Strike-Through Performance
- Strike-through performance assessed according to standard EDANA test methods
- Minimal impact on hygiene finish performance when included at 2% by weight
- Samples were coated using a range of nonwoven weights, treatment methods and treat rates
