Cosmetics Formulation Development

1. Bis-PEG/PPG-16/16 PEG/PPG16/16 Dimethicone can coordinate formulas with high electrolyte e.g. 10% Hyaluronic liquid + 5% b5 (may contain only 1-2% oil) and is it necessary to Magnesium Sulfate to increase stability? 2. If you want a light formula, such as a spray formula or a formula that requires a low concentration (may not contain any gelling agents), the team says to use it. Silk Lotion Maker 2-3% with Polysorbate 80 1%, but if changing is Silk Lotion Maker 3% with Light Lotion Maker 1- 2% can do it or not And will affect the separation or not if the formula contains 30% oil + silicon. 3. In theory, some types of silicone can be coated. Therefore, using the two formulas together (applying on top of each other), for example the first formula with Trisiloxane + aqueous solution, coat with formula. The second formula has the same ingredients as the first formula. The question is, will the silicone in the first formula interfere or hinder the absorption of the aqueous solution in the second formula or not? Trisiloxane , Dimethicone 1Secs and SiliconeGel (Ultra Clear) which is the most suitable and SiliconeGel (Ultra Clear) is a volatile silicone or not.

Hello

1.Bis-PEG/PPG-16/16 PEG/PPG16/16 Dimethicone can coordinate formulas with high electrolyte e.g. 10% Hyaluronic liquid + 5% b5 (may contain only 1-2% oil) and is it necessary to Magnesium Sulfate to increase stability?

Silk Lotion Maker doesn't tolerate electrolyte well, but Hyaluronic Acid and Vitamin B5 No problem, can be used with Silk Lotion Maker Yes Magnesium Sulfate is used to add Stability of emulsion formulas in the system Water-in-Oil But Silk Lotion Maker is an oil-in-water system, so if you want to increase stability, use ClayThick or Xanthan Gum (but if only 1-2% oil There is no reason to increase stability. because this oil Can be easily soldered already)

2. If you want a light formula, such as a spray formula or a formula that requires low concentration (may not contain any gelling agent), the team told us to use it. Silk Lotion Maker 2-3% with Polysorbate 80 1% but if changing is Silk Lotion Maker 3% with Light Lotion Maker 1- 2% can do it or not And will it affect stratification if the formulation contains 30% oil+silicone

not as suitable as adding it? Polysorbate 80 in small quantities (1%) in this formulation. The reason is because the manufacturer has already tested that. can work well together

3. In theory, some types of silicone can be coated. Therefore, using the two formulas together (applying on top of each other), for example the first formula with Trisiloxane + aqueous solution, coat with formula. The second formula contains the same ingredients as the first formula. The question is whether the silicone in the first formula interferes with or interferes with the absorption of the aqueous solution in the second formula

. hold It is heavy and non-volatile, but because Trisiloxane evaporates quickly, so no problem.

4.If you want a serum formula which is light, easy to spread and dry quickly between Trisiloxane , Dimethicone 1Secs and SiliconeGel (Ultra Clear) which is the most suitable and SiliconeGel (Ultra Clear) is silicone. Is it volatile?

Totally volatile but Silicone Gel (Ultra Clear) will have some parts in the gel texture. non-volatile (about 10%), which leaves a soft smoothness on the skin Compared to the other 2 types that members have given examples It doesn't leave anything on the skin after it's all evaporated. Therefore, you should choose according to the characteristics you want.
