Water-in-Oil EZ™

Water-in-Oil EZ ™ is Cetyl PEG / PPG-10/1 Dimethicone with medium molecular weight function. Easily binds water to water-in-oil formulas, giving the serum a soft and smooth texture. Good coating Which is the highlight of the water-in-oil serum / cream, which can be freely formulated with electrolyte. Does not weaken the formula or cause separation.

 

Difference between Water-in-Oil EXTM And Water-in-Oil EZTM

Currently, the most important influence on the efficiency of the emulsifier is the molecular weight of the linked polymers, the larger the emulsifier has the better the co-ordination efficiency.

Water-in-Oil EXTM Have larger molecular weight Water-in-Oil EZTM Not less than 2 times, making it possible to bind formulas that are difficult to bind, such as having a high percentage of oil, a small proportion of water, etc.

In general formulas, it is recommended to use Water-in-Oil EZTM Which is cheaper But if it is found that it cannot synchronize Or there is a problem with stability Therefore consider using Water-in-Oil EZTM

 

Examples of popular products using Water-in-Oil EZTM:

- Concealer / Balm / Foundation / Cushion (Oil part: Water-in-Oil EZ TM + Wax + Oil / Silicone 30-35%, water part 65-70%)

- Sun Screen (Oil part: Water-in-Oil EZ TM + Sun Screen / Oil / Silicone 30-35%, water part 65-70%)

- Cream / Serum to nourish dry skin (Oil part: Water-in-Oil EZ TM + Oil / Silicone 20-35%, water part 65-80%)

 

Water-in-oil emulsion description

Usually, skin care creams or gels are made from an oil-in-water emulsion or encapsulation of the oil with water.

 

The left picture is oil-in-water emulsion, the right picture is water-in-oil emulsion.

The highlight of the oil-in-water emulsion, which is used as a cream or gel in the skin, is more than 95% of all products, it is non-greasy, easily absorbed by the skin. Does not coat the skin well. Due to the nature of the product is coated with water When applied to the skin It gives a feeling that water is applied to the surface. It is also not waterproof. Since the formula is coated with water, it will be rinsed off immediately. It is also not suitable for make-up formulas such as BB Cream as it cannot spread powder and foundation evenly on the skin. This is because the pigment is usually oil-soluble. When present in an oil-in-water base, it does not spread well both in formulas and on the skin.

 

The advantage of water-in-oil emulsion is that it can be a good coating. Ideal for dry, severely dehydrated skin and needs a coating so that it doesn't lose water easily. They are ideal for use as a night cream, night serum, or as a moisturizer in dry weather, cool weather or in air-conditioned rooms. The key feature of this water-in-oil is its waterproof ability. And durability on the skin Because the formula is coated with oil Therefore it is durable and stays on the skin for a long time And can be waterproof It is ideal for both make-up and sunscreen formulas. Which requires durability And cover (spread easily and evenly) on the skin

 

More instructions for use:

- The thickening of the recipe depends on the amount of water in the recipe, if there is a lot of water, the thicker the formula will be.

-Should not contain more than 5% of Cyclomethicone, Dimethicone, Ethyl Alcohol, Propylene Glycol, Butylene Glycol, Glycerin in formulations using Water-in-Oil EZTM due to stratification.

 

Difference between Water-in-Oil EZTM And Water-CapsuleTM

Either Water-CapsuleTM And Water-in-Oil EZTM It is used to create a cream or serum formula that has the same water-in-oil properties, but with the following differences:

- Water-in-Oil EZTM Good workability in electrolyte formulations. Without any effect Examples of substances with high electrolyte are: DMAE , Sodium Lactate While other binders include Water-CapsuleTM Unable to form meat Or must be used in very high quantities

- Water-in-Oil EZTM Can support oil, silicone up to 35%, but Water-CapsuleTM It can support up to 20% of the oil if the formula focuses on the use of silicone or has a high oil content. Please choose to use Water-in-Oil EZTM

- Water-CapsuleTM The formula can be easily thickened with a stronger / longer blend Will get a thicker texture, but in adjusting the thickness of Water-in-Oil EZTM Must have to adjust the mixture rate or use Gel Maker / Thickener

 

Important - mixing process

Mixing must bring a portion of water. Add to the part of the oil. By adding little by little and blending or stirring continuously, if the opposite, the oil Add to the water portion It will take much longer to stir or spin. Or may not be compatible at all

Detailed steps:

1. Bring Water-in-Oil EZTM Mix it into the oil section. (Any kind of oil such as Isododecane, Mineral Oil, Jojoba Oil) Stir or blender to a homogeneous mass.

2. Prepare the water portion by mixing the water with any ingredients dissolved in the water.

3. Bring a portion of water. Add to the part of the oil. By gradually adding little by little And the poor are homogeneous And then continue to add Do not add them all at once. Because it will take a very long time to blend or the recipe is poor

 

Please see the vdo example showing you how to mix. https://www.youtube.com/watch?v=u8GGITnUqx4

 

* If the formula has a lot of water The recipe will be thick. If the formula has a lot of oil or silicone The recipe will be liquid. It is recommended that the oil + silicone ratio is 20-35% if using heavy oil. Please reduce the proportion of oil *

 

* If the formula is over 35% oil, please consider using. Oil-FixTM To help increase stability Prevent separation *

Thickening formulation using Water-in-Oil EZ ™ to blend and create texture.

It can be done in 3 ways.

1.Add the approximate proportion of water (And reduce the proportion of oil)

2. Fill Water-soluble Thickener such as Xanthan Gum In the blended part to get the gel texture first Very little As required And then follow other steps as usual The thickening of the water Will make the formula thicker Please see also an example of the thickening effect. Xanthan Gum According to the formula below

3. Fill Thickener that dissolves oil such as Hectorite Gel In the oil section Blend to combine the oil.

4. Fill Wax In the oil section

 

For Water in Oil formulations (both water and oil are available using Water-in-Oil EZ ™ as a synergistic formula) we recommend more. Magnesium Sulfate 1% to help increase the stability of the formula. Reduce the chance of stratification

 

Usage: It is a water-based binder with oil and silicone that can be used in all formulations.

Mixing method: Mix in the oil well. Then the water part of the water gradually added to the oil part Please read more details above, the formula should be used. Magnesium Sulfate 1% to help increase the stability of the Water-in-Oil Emulsion.

Rate of use: 0.1-4% (1-2% is recommended for most formulas)

Product characteristics: Light yellow clear liquid

Solubility: Can dissolve in oil

Storage: Can be stored at room temperature But close the bottle tightly And sealed from direct sunlight or heat, the product is at least 2 years old

 

INCI Name : A. Cetyl PEG / PPG-10/1 Dimethicone

Can be used instead of PEG / PPG-18/18 Dimethicone by efficiency In the higher oil compatilibty due to the cetyl pin and lower thickening Makes it possible to make liquid formulas well.
