The SY-DP series is a line of ether polyols obtained by the addition of the polymerization of propylene oxide to diglycerin. The SY-DP series has lipophilic properties and an oily feel, owing to the addition of propylene oxide, but it also has moisture-retention and hydrophilic properties derived from diglycerin. The SY-DP series can be used in various types of cosmetics as a moisturizer that does not cause stickiness.
Skin-care cosmetics (lotions, creams, etc.) |
Moisture retention action The SY-DP series spreads smoothly on the skin with a light feel and provides moisture retention. When formulated together with glycerin, the SY-DP series does not reduce the moisture-retention power of glycerin but reduces stickiness and improves spreading smoothness. |

The SY-DP series improves the foaming and cleansing power of body and facial cleansers. The SY-DP series can be formulated in a water-based make-up remover, as it blends easily with make-up ingredients, to greatly improve removability. The SY-DP series also leaves skin fresh and well moisturized after cleansing. |
Other applications | The SY-DP series is an amphiphilic compound, so it can be used as a solubilizer or solvent of oil ingredients. Also, SY-DP series products are non-volatile. |
