3

Formula innovation 1

Replacing cyclopentasiloxane (D5) reduces costs by 40%
Solve the problem of silicone oil residue (zero residue detection)

4

Formula innovation 2

Improve the uniform distribution of sunscreen (SPF value fluctuation is reduced by 30%)

Operation Guide

Makeup formula application:

Liquid foundation:

Addition amount 8-15% (replaces 50% silicone oil)

Needs to be premixed with a wetting agent (such as PEG-10 polydimethylsiloxane)

Mascara:

Volatile matrix accounts for 20-30%

Avoid direct heating with high wax content (>25%)

Sunscreen spray:

Mix with ethanol 3:7 to improve uniformity

Pressure canning requires sealing compatibility testing

Storage conditions:

Nitrogen-filled and sealed (residual oxygen content <0.5%)

Keep away from heat sources (storage temperature <35°C)

FAQ

Q1: Impact on SPF value?

Improve the dispersibility of titanium dioxide (SPF fluctuation ↓20%)
Q2: The ratio of replacing mineral oil?

1:0.8 equal replacement (skin feels more refreshing)
Q3: What causes crystallization?

Storage temperature <5℃ (recovery in a 40℃ water bath)
