Silasoma

Capsules containing UV absorbers

Silasoma is water dispersion of capsules, encapsulated UV absorbers.

Concern related to the safety of UV absorbers and their heavy oily feeling on the skin lead us to encapsulate the raw material, we have developed with our own original patented technology, resulting in the successful development of Silasoma, an ingredient that protects against UV rays and is gentle on the skin. In addition to being very safe, Silasoma also has a useful feature in that it provides a soft and light after-feel that is devoid of stickiness, and that it allows the formulation of surfactant-free sun protection products. It can also be incorporated into hair care products.

Its safe and reliable design prevents skin penetration!

The Silasoma series prevents the absorption of the UV absorbers into the stratum corneum (horny layer of the skin) by encapsulating the UV absorbers that cause skin irritation.

Verification

We tested the safety by encapsulation of UV absorbers.
A lotion containing Silasoma and another lotion, which was formulated with the UV absorber in the same amount as that inside the capsule, were applied to each arm, respectively. Both were left on the arm for 60 minutes. Afterwards, any formulation remaining on the skin was wiped off. The stratum corneum cells were stripped off with tape, and the amount of UV absorbers adhering to the stratum corneum was measured. The stripping with tape was repeated to examine the degree of penetration into the stratum corneum.

Please feel free to choose products that suit your needs.

Silasoma has a variety of features depending on the combination and type of UV absorbers encapsulated. The customer can select the product count depending on their needs.
