We Love Foam: Mild Skin Cleansing Foam
We are probably all obsessed with SAPONIFICATION, but there are people who do not apply REAL SOAP on their face, and a mild cleansing fluffy foam based on plant surfactants is a luxury for everybody. It could be a fast present for someone while you don't have any cured soap.
In this project we have applied only natural, plant based surfactants. This foam with only about 3% active substance is much more milder than any soap and is very suitable for cleansing dry and sensitive skin. We have done without EO-containing surfactants, PEG-containing solubilizers and we applied no color at all. Of course you are free to apply a few drops of a food color or any suitable liquid color. The preservative applied is a broad spectrum preservative effective at very low concentrations.
Geranium floral water and Geranium essential oil applied in this project are well known to be skin friendly ingredients suitable for each skin kind but specially recommended for mature skin. Panthenol and glycerin provide the skin with moisture.
Before we start:
Please have a look at our previous posts about hygienic manufacturing practice in a cosmetic lab and basic equipments for a cosmetic lab.
For this project (100 gr facial cleansing foam) you need:
1,15% Sucrose Cocoate (1,15 gr)
5,0% Cocamidopropyl Betaine (5,0 gr)
2,0% Coco-glucoside (2,0 gr)
10,0% Geranium floral water (10,0 gr)
5,0% Glycerin (5,0 gr)
0,5% Panthenol (0,5 gr)
5,0% PEG-free solubilizer, Symbio® Solv XC (5,0 gr)
0,2% Essential oil of Geranium (0,2 gr)
0,10 % Medcide® KR (broad spectrum preservative) (0,1 gr)
Probably (1-2 drops) Lactic acid to adjust pH
boiled distilled water (to balance 100%, ca 72 gr) , not necessarily cooled
2 glass beakers (50 and 250 ml) or other suitable containers for mixing
pH indicator paper or a pH electrode for reading pH
disposable pipettes
Glass rods or other suitable instruments for mixing
A foam dispenser
Instruction:
One:
You may apply hot distilled water for this step. Weight Sucrose Cocoate in a 250 ml beaker and add boiled hot water to it. If your water is already cooled down, no matter. Put the beaker in a water bath. Temperature should be round 70o C. Stir now and then gently with hand or apply a magnetic stirrer at low speed.
Two: After Sucrose Cocoate is dispersed in water (it is still not a clear solution), take the beaker out of water bath, let the mixture cool down to around 30o C. Then add Cocamidopropyl Betaine, Coco glucoside, glycerin, panthenol and geranium floral water and mix gently. This would be phase A.
Three: Mix the solubilizer and Geranium essential oil in a small beaker. This is phase B.
Four: Add phase B to A and stir further.
Five: After the mixture is homogenized, check the pH with an indicator stick or a pH-electrode. In our case, the pH was around 6 and we didn't add any lactic acid. You may adjust the pH with 1-2 drops of lactic acid between 5,5-6,0 if the original pH is higher. However notice that applying lactic acid may increase the viscosity which has in its turn a negative impact on the function of the foam dispenser pump.
Six: Add the preservative.
Seven: Fill the foam in a foam dispenser bottle. Done. If the viscosity of the foam is not suitable for your specific dispenser, you may dilute the foam with distilled water to a suitable viscosity.
